The early hang glider power units in the late 70s (like the Soarmaster) were fitted to the frame. However if you get into a negative g situation (straps go loose, so the pilot no longer has pitch control) then the high thrust line will push the glider over into a tumble. It's much safer to attach the power unit to the hanging mass, i.e the pilot. This is why they stopped making them like this and Mosquito, Wasp, Doodlebug etc, as well as every weight shift microlight trike always has the thrust on the pilot (or trike), not on the wing. The e-help is a great modern example of an electric power unit on the pilot. With low amounts of thrust and smooth coastal air then you'll get away with this like they did in the late 70s, but if you get tempted to start putting more thrust on it or flying it in spicier air then it could get dangerous.
We are aware of these old dangerous configurations with heavy powerful motors and we have tried many different configurations over many years, for example: one motor on the nose, two motors either side of the pilot, etc. but we were thrilled when we tried the motor at the current position because for the first time we found no change in pitch control, on a low performance HG, once flying. This is due to the line of thrust being opposite to the centre of drag for low performance hang gliders (look at the billow, dihedral, and angle of attack, at trim, for low performance hang gliders). Also, these units are generally very low power and just extend to abilities of a low performance hang glider to act more like a high performance hang glider in so far as its ability to jump from hill to hill along the coast, for example and also to fly in conditions that are too light for normal flight. Also, the position of the prop is very safe and the static balance is perfect. We love them and have been using them for many years now.
@@robertberndes7878 as long as you're aware then I agree that sounds reasonable. It's just that it's always tempting to add bigger motors and more power and start using in more situations! At some point that would become dangerous. Although with electric there is the possibility to have a system using accelerometers to automatically kill the power if the wing becomes unloaded, which wasn't an option for those early pioneers. Although if you start to rely on that as a safety critical feature then it would need a really high level of reliability.
@@robertberndes7878 I can see this useful in situations to get launched in areas where access to a launch has been lost , or due to terrain that makes difficulty launching. Simply launching on the beach and flying up to the lift, might be preferable to a multi person wire launch on a precarious cliff edge. I was skeptical about the high thrust line , but given low power applications , and using in smooth marine air, I think it could be used safely.
there could be a easy solutions to fix this conundrum. I have several ideas that could revolutionize hanggliding. I'm trying to contact different manufacturers for a collab.
you could simply put a motor on each side strut (instead of side wires). Side struts instead of side wires should be generalized in free flight hanggliding by now. The philosophical design approach to current HG is not the correct one. Sure light weight is important, but it needs to be put in context of other considerations.
I can’t stand being outside without sunglasses, and wear really well fitting safety glasses when I’m on my motorcycle to keep the wind out of my eyes. How you are out there flying around in the bright sky, wind blasting in your face and no eye protection baffles me. Love the concept though! I am a remote control pilot and love slope soaring , I have a few powered gliders too.
Sunlight doesn't bother most people. We actually like it. You might have a condition that prevents your irises from contracting in bright light, so you have to wear sunglasses when you're outside in the sun otherwise the bright light is painful for you. For most people it isn't a problem.
Excellent, guys! I built a working hang glider when I was going to tech school in Phoenix, AZ back in '72. Bedsheets, bamboo carpet poles, and nylon twine. Drew it on a napkin and built it once I had the materials. It got me off the ground for about a minute before a gust told it to fold on me. School got busier about then and I never did go back to it. Fond memories seeing you fly them so easily. xox Curious of the cost nowadays, especially for a powered version.
@@robertberndes7878 did the motor position pitch the glider downwards?? The mosquito motor kit puts the motor next to the feet to avoid pitching the glider but i want to know if you had any problems with this position of the motor
Did the same thing, in the same place, at about the same time! Got scrap bamboo from carpet shops, plastic sheet and reinforced strapping tape. Drove over towards Tempe and flew it off those little buttes just north of the Salt River. Our kite lasted for about one afternoon of ground skimming. Almost set my butt down on a barrel cactus. Latter I bought a old style "Lark" rogallo wing for about $500 and would drive up to fly the cinder cones east of Flag. God, even today's lowest-performance gliders would have been freakin' amazing back then!
BEEN FLYING RC OFF THE BEACH FOR 40 YEARS! SMOOTH AIR WHEN OFF THE OCEAN OR DOWN THE BEACH!, STARTING FLYING ELECTRIC IN 1988! THANKS FOR SHARING. HAD THREE HANG GLIDERS AND NEVER FLEW THEM. MY LOSS.
Thought for second you couldn't get back up wind. I fly wills wing Falcon 4 , been trying to figure out a way to do this. Off the king post... brilliant.
Maybe a metal panel under propeller rotation could be good to prevent problems in case of prop failures . Probably that brushless has low rpm but those props are big enough to penetrate the wing
I think it requires about a 12hp motor which gives about the 19kg of the first example to float about forever. What is important is that the distance from the hangpoint where all the tubes meet is as small as possible. It is at this point where crossbars keel hangpoint meet that all the aerodynamics are worked out by the glider and you keep flying or not. You are putting 100kg of weight about 2 meters hanging below so 20kg pushing 50cm above is probably just about ok. The glider dose not care where the push comes from it is up to us to keep this safe so it does not prevent your fundamental control skills being overwhelmed by the motor. I have a paramotor which gives up to 70Kg thrust but with a Propellor whose center is 50cm from my back and it works fine. Before I instructed on powered trikes with maybe 100kg thrust but then you have a fixed distace bar seperating you from the hangpoint and everything has now changed from hangliding to an aeroplane david
I think the other thing we have discovered is that the motor should be situated close to the centre of DRAG. The kingpost mount seems to be pretty close to that.
I can't suggest paragliding strongly enough! I want to fly hang gliders too one day, but I my paraglider harness serves double duty as a backpack for the wing, so I just keep the whole thing in the trunk of my car and fly after work! Seagulls are totally fine sharing the air with me over the ocean cliffs. It's the least expensive form of aviation! Just look up a school and get good training. I dreamed of flying paragliders for 20 years before I finally did it, and it's better than I imagined. I want everyone to fly!
There is so much potential on this, it's insane! Install a self stick solar film on the back of the Hangglider and you have a fully solar powered Glider. Look at the SunSeeker solar sail plane, much heavier, smaller square meter, still works. I want it so bad.
@@JT-cf7dq1m2 will bring about 20W average. With direct sun lot more. Foils bring up to 10%. How much area does a glider have? Lets say 7m2. Thats about 140W. Not much but the battery wont dry up so fast. If the solar foil doesnt bring a negative effect to areodynamics that idea could work. Over time the material will be better. Maybe in 5-10years it will be practical, maybe sooner maybe even today. Who will find out and make a cool youtube video about it?
So my take away. The 19kg is maginal for self launch on flat. The others seem like a get out jail free card if get to far from a safe landing area. Winch stuff is pretty cool, either they overloading the winch, or not getting enough AOA on launch for a big climb out.
Yeah, that's pretty accurate although we still have to test the 19lb again we don't know if we are just in ground effect in a nil lift situation. We have increased the thrust by going with slightly higher voltage and may be around the 23lb mark now. Still have to try again on level ground, no lift situation.
We think somewhere around 1500 USD but we are still working it out. In the For a more detailed description of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
I can turn on my music by myself. But sadly Ihave no E-glider to listen (let alone a bunch of them to compare). It would be helpful to hear them without music. THX
Will will try to upload a video at some point so you can hear the mtors without music. For more details of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
Very light... The batteries are the heavy bit. How ever many of them you want to carry... The motor weighs less than a kg. We have only been in ground effect continuously but have now upped the power by increasing the voltage and going for 3 props over two but we haven't yet tested the new configuration. There will be a video as soon as we do :) The next video will show the original two motor configuration which took off from the ground and climbed straight up with plenty of power. Look out for that one :)
We are thinking about it.... :) For a more detailed description of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
Have you experimented w/ mounting positions and thrust direction? I'm thinking a reversed (pusher) thrust mounted on the keel boom might be a better position. You seem to have experienced no control issues. Electric propulsion is certainly the future of motive power, we just need battery tech to up its game and we could be flying quietly into said future.
Only sustain. There is a size limitation between the wires and the sail. We really enjoy the advantage it gives us otherwise we wouldn't bother of course :)
Hi, I'm very light 56kg and I fly a Finsterwalder packable HG. This little motor could easily lift me up. I'm interested in buying please. Best wishes Lauren
We are still working it out but hope to have more info out soon. For a more details of the motors please see description in "Why do girls prefer hang-glider pilots" on the same channel
Besides that looking awesome, it looked like you were near the Rockingham grain terminal at one point. 🤷♂️ So just incase you know🤔 Can you tell me how high it is....I’ve wondered for ages as I can clearly see it from Halls Head beach?
Hmmm. Don't know but you got the location right :) Crazy that you can see it from there. Of course it could be worked out knowing the distance you are from it and the amount you can see of it. (eg. half way up) and knowing the horizon is 16nautical miles but I'm sure none of that is very helpful :) I'll ask.
My original thoughts as well! - before we made the small ones - but we think differently now. For more of our thoughts and experiences on the subject please see the description in "Why do girls prefer hang-glider pilots" on the same channel

Looking like you’re basically having a little extra flight to get out of a hard spot but nothing yet to take off from flat land and climb to thermal altitude. Very cool but I think you’re going to need closer to 40-50 kg of thrust to be a real option. Then of course the extra weight of battery and where to place it.
That's right and that is enough for most of what we do. We are more interested in a helper motor because it is easy, light and hardly noticeable when not in use. For total flight autonomy we know that with two predator motors at 19lb thrust each (17kg total) either side of the pilot - we climbed to 100ft easily from flat ground. We feel that we are almost there with that model but until we are out of ground effect we cant say for sure and yes, there is a lot more weight with the bigger motor.
Oops 19kg not lb! Sorry. So 38kg can get you up from flat ground but that was a long time ago so we are a bit fuzzy on the details. The props were much bigger - 28inch and the original one used motorbike 12v, lead acid batteries strapped to the pilots back!
Like where you’re working the lift from the building. Cool to be taking off from low hills without having to jump off of mountains,eliminating a lot of stress. How long does the battery last? What’s the price of the motor
That is one of our biggest goals with the project. A lot of hills are not accessible as you know and starting off on a low primary dune or hill is a great way to avoid a long difficult hike carrying a glider.
Battery time varies with use, and size, of battery pack and motor configuration. As a guide though, with our smaller helper motors, we can use them intermittently for hours or, with the 12Ahr pack - full revs for 12min. It really just depends on how many batteries you want to carry around. We get a lot of fun out of a small light pack and that is usually our preference. We often have another charged pack on standby but rarely end up using it.
Just that little extra lift at the right time would greatly extend most flights. A missed thermal on a cross country flight results in a lot of walking and difficulty.
Those motors look like they're right at the threshold of being enough, so I'm guessing the rest comes from slope soaring? Yet it seems enough to help keep in that pocket of upward moving air. Although it'd be funny to see this setup used at one of those Red Bull Flugtag events. (If the conditions were right. Instead of diving into the drink, actually having a real chance of flying off.)
G'day, Well then, either look at History, Or Think it through....(!). Rogallo Hang-Gliders are Controlled by WEIGHT SHIFT. The Pilot is an Intelligent Pendulum, Hanging from the Theoretical Centre of Pressure of the Aerofoil... Control in Pitch and Roll is effected by using the A-Frame as Leverage, With which to change the Wing's ATTITUDE Relative to the Pendulum's Suspension Harness - Which itself points to the Vector from which "Gravity" or Change in Angular Momentum is pulling the Pendulum. Therefore, Thus, and Because..., ANY Thrust applied to Either the King-Post (as shown here) or to the A-Frame's bottom Corners, as ye enthusiastically hypothesise WILL impart a Pitching-Moment, Proportional to Thrust and Leverage. This thing has 19 Kg of Thrust about half a metre above the Wing, with a Metre or 1.2 Metres worth of A-Frame "height" below the Wing. So the 75 Kg - 90 Kg Pilot has a 2.1 : 1 Leverage Advantage over a Pitch-Input one quarter that of how much Weight he can shift. So....., this is barely sufficiently powerful as to be safe to take of into ABSOLUTELY Still Air - but it's too gutless to be safe in Wind, Turbulence, or patches of Sink ; and adding enough Power to be safe-ish to fly would mean doubling the Thrust at minimum - tripling it would be much better - but then the Pitchdown would be impossible to correct for with Weight-Shift. So, it's a tantalysing Dud. Not worth doing. Historically, go looking for the Film Clip from the mid 1970s featuring the Lunatic who strapped a Propane Bottle to his Backpack, feeding a pair of 40-pound Thrust Gas-Jets mounted at the bottom Corners of the A-Frame of his 90-Degree Nose-Angle Rogallo...; and had the boundless Optimism required to launch himself off a Hilltop into the Wind with both Jets running at full-blast. Wearing Jeans and a T-Shirt, with an open-face motorcycle Skid-Lid for Crash-Protection...... It took off, and tried to climb-out at a 45° Angle as he desperately attempted to pull himself up level with the Bar..., Vainly struggling to lower the Nose - but of course it stalled, fell down, broke and collapsed onto him - and then the Dacron on the hot Jetpipes melted, and ignited, and shrunk down onto him as well..., burning him horribly. He was lucky indeed, the theory goes, that his Propane Backpack didn't go all B.L.E.V.E on him... So, no. Pushiness, or Pulliness, on a Rogallo... MUST be precisely Aligned THROUGH the Wing's Centre of DRAG. When Aerotowing Hangies, we used a Bridle from a Tube extending the Fin-Post of the Tug to a Release-Hook on the Tailwheel Spring with a Steel "Bull Ring" sliding freely in the Bridle tied onto the Towrope and a (2-G) Weak-Link from Bridle to Tow Release..., thus the Towrope Loads go from the "Bull-Ring" to the (Pusher) Engine's Thrust-Line which is halfway between the top and bottom of the Bridle. And the Bull Ring slides up or down to adjust for Formation-Keeping difficulties. At the other end of the Towrope another Bull Ring pulls on another Bridle, one end attached to the Apex of the A-Frame (pulling against the Wing's Weight & Drag) with a Bowden-Cable Release attaching to a 1-G Weak Link, and the other end of the Bridle joining the Pilot's Harness via a Slip-Knot, pulling against the Pilot's Weight and Drag. If you want to get deep into the subject, then feel free to backtrack me to my "Personal Aeroplanology..." Playlist, therein to find and enjoy, "Aerotow Launching Rogallo Hang-Gliders...; Development & Implementation Of The Lockout Index !" Back in the mid 1990s I had quite a bit to do with Aerotowing Rogallos, and some Ultralight Sailplanes too. Have fun, Stay safe. ;-p Ciao !
@@WarblesOnALot Man, I HATE a know-it-all! 😁 That was a great explanation, obviously you know your stuff. We have hang-gliders here on the Monterey peninsula, but I've never seen a motorized one locally. I just wonder how far one with a mid-sized motor and decent pilot could get if they were trying - use the motor to gain altitude or find a thermal and then shut it off till needed again. I envision hundreds of miles, but that's just me.. Would it be worthwhile to create such a competition? (Hint...)
@@thesoundsmith G'day, Ah, well, yeah...; I aim to function at the level of a Competant Smartarse (!), because such is tolerable - it's really only the incompetent ones that people can't stand... Well, in 1978 a Brit. named Robin Cook flew the first "Microlight", as they called them in the UK back then, across the English Channel using a 10 Hp McCulloch Chainsaw Motor atop a "Stick"projecting above the Wing...; on a VJ-23e "Swinging", a Foot-launched Aerodynamically-controlled Hang Glider with Plywood Spar and Foam Ribs in a Cantilever Wing on an Aluminium Fuselage-Tube supporting the Cruciform Tail with Fins, Rudder, Stabilisor and Elevators, at one end and the Wings and Hang-Cage at the other - featuring Parallel Bars and a Swing-Seat with a Hang-Harness...; all 3 Control Axes were managed with a single Side-Stick on the Righthand side. The VJ-23 Swingwing was Volmer Jensen's outraged response to the early Rogallos which struggled to achieve 4:1 L/D...; whereas the VJ-11, a Biplane Hang Glider Volmer had been selling Plans for since 1948 achieved 6:1..., and so the VJ-23 Swingwing beat the snot out of every Rogallo around, in '73 or so, with a L/D of 9:1. Jensen had motorised the Swingwing in 1976 - after hearing of Macready putting a Chainsaw Motor on his Icarus (Tail-less Swept-Wing Hang Glider, with Drag Rudders at the Tips, hinged on the outer rear Interplane Struts...) in 1975 - the first half of the Year, I'm guessing...; and by December 1975 Ron Wheeler at Waverley in Sydney had failed to take-off in a Victa-120 Lawnmower Motor on a Tweetie (Foot-Launched Aerodynamically-controlled Hang Glider featuring Sailboat Masts for Fuselage Tube and Leading-Edge Spars, Single-Surface Wing-Skins with a Bolt-Rope hemmed into the Luff-Edge and thus secured in the Sail-Track on the Mast..., all Cable-braced with the Skins drum-tight and Cambered Battens made of bent 1/2-inch Aluminium Tubing sewn into Pockets in the Wing-Skins..., with an A-Frame for the Pilot in a Hang-Harness using Weight-Shift for Roll Control and All-Flying Stabilators and Finless Rudder driving Pitch and Yaw from a Righthand Side-Stick...) Wheeler had added Wheels to the bottom of the A-Frame, and a Plastic Seat, with Elevator and Rudder now on a central Joystick. The 2nd Prototype "Skycraft Scout" again had a Victa 120 - tagged a "Pixie Minor" 8 Hp Motor ; but with a 3:1 Bicycle-Chain Reduction-Drive, it did fly, at Sea Level, in October or November 1975. Then when the Dep't of Transport let Wheeler know that if they heard of it flying again he would be prosecuted, he responded by inviting them to inspect his doings, observe what it could do, and then say WHY he should be prevented from playing such harmless Sillybuggars for the fun of it. So in January the DOT showed up, and, "The 8-Hp, 1975, Red Baron Skycraft Scout ;...." was duly demonstrated to the Beaurocrats, who laughed so hard they went back to Canberra and in August 1976 Air Navigation Order 95.10, which had been written around the 3rd Prototype Scout, was gazetted - exempting ALL such "Minimum Aircraft" as defined (MTOW 400 Pounds...) from ALL OTHER Air Navigation Orders - subject to provisions (Not to exceed 300 ft above Terrain, not to cross paved Roads, not to overfly Municipal Areas, Race-Meetings, Public Gatherings or Regattas, not to come within 500 ft Vertically or 1,000 ft Horizontally of any Cloud, not to approach ANY Licenced Airport or Controlled Airspace closer than 5 miles..., and Aerobatics of any kind were VERBOTEN. Which is why the rest of that Movie Title is, "...; World's 1st Legal Minimum Aircraft !" It wasn't till about 1982 that the US brought in their FAR covering Ultralights - basically a copy of ANO-95.10...; so, for a while there Oz was leading the Revolt against Lycosaurus powered Cabin Spamcans on Training-Wheels, flying on Autopilot or trying to fly like an Autopilot..., The FIRST Rogallo with an A-Frame instead of Parallel Bars was built by John Dickenson, of Grafton NSW, Oz, in 1963...; Bill Moyes was the first to fly it, but he didn't think it up, or build it (!). Anyway, because the VJ-23 was a pain in the bum to build, the tapered Wingplan meaning no two Ribs in one Wing were the same size or shape, and the 36-ft span Wing was one-piece and a pain to transport, and Aluminim/Foam/Resin/Wood was beyond a lot of Scratch-builders anyway. So Jensen started again and in '78 the VJ-24 Sunfun appeared, with the same Span, Aerofoil, and L/D - but the rectangular Wingplan meant ALL the Wingribs are identical, and the whole Airframe is pop-riveted Aluminium, fabric covered ; and the Wings are built separately and bolted to the Fuselage-Boom Tube, braced by Lift-Struts off the Hang-Cage. I was the third owner of the Red Baron Scout..., if you check out, "National Transportation Museum ; Visiting My First Aeroplane !" you can see my "pilgrimage" to visit it last year (shortly before starting treatment for Stage-4 Tonsil Cancer....; which was tough but it worked - though when I made the Video I was half expecting to be on the Daisy Up-Pushing Brigade by September.). My VJ-24w is a bit of a rarity, I meddled with the Design of the Trailing Edge and Undercarraige while a friend was scratch-building it..., then I bought the Project after he'd started on a 24, modified it to 24e (engine) standard for a 10 Hp McCulloch in the Hang Cage, then gone to a 24w (wheels) version with my idea of a (Bungee-sprung Floating-Axle) Undercarraige, and he put a 22 Hp JPX Pul-425 on it rather than a 15 hp Yamaha stipulated by Volmer. When I got it I redesigned and rebuilt the Wing Leading Edge in Sheet Aluminium replacing the original 1.5mm Foam Styrene and Dacron and Resin "1/2 Sandwich Shell"...; and then it got my idea of an actually streamlined Pod, a Spring-deployed Parachute BRS, and a panel of Instruments. Thus, when it came time to Test Fly it, nobody had any better idea than me as to what it might be likely to do, and it was my Pop-Rivetry & I designed and carved the Propeller, too. So I have actually made the First Flight on one genuine (Mystery Bag) New Prototype... And it took me 3 months to rack up 6 hours and be happy with the Flight-Test Program ; and after another half an hour in the logbook - guess which Dickhead agreed to a Downwind Take-off attempt in a 200 yd Paddock, with an Ultralight Motorglider (!) ? That was a day when my Smartarsery All came Unglued At once... lol...! So, yeah, if you can stand the Hillbilly production values (?) then you might enjoy scrolling around in my "Personal Aeroplanology" Playlist ; because the stories are pretty good, and I try very hard to not be wrong. I think my Bullshit Content hovers around 5% ; but I never know if that means I'm 5% wrong about EVERYTHING - or if 19 times out of 20 I'm totally correct an the next opinion I hold will be utter Bullshit...(?), so all I can do is to keep trying to get shit right (!). I think the most successful Powerpack conversions for Rogallos had the Motor and Fuel on the Keel, Fuel ahead and Motor behind the A-Frame, with a Propeller at the back of the Keel, shaft-driven, with 2 Skids poking down to protect the Prop.-Tips. Why not put the LiPo's Up near the Nose, Balancing a Motor Down behind your Toes... Where The Prop. won't chop 'em off When for Landing ye Flare...? To be safe you need to be able to climb at 250 Ft./Min., and the Thrust MUST be aligned with the Drag. But a Motor and Battery out of a serious Electric Chainsaw should make a Rogallo go uphill...(?) - and if not then gutting an Electric Motorcyle should go very well indeed. I hope to thus Electrificate the old Jensen, one day (!). Have a good one. Stay safe. ;-p Ciao !
Ducted fan motors are not as efficient at making thrust, so much so that to get the equivalent thrust of 19kg seen here, the battery's would be toast in half the time, not to mention the noise would be immense due to the high rpm...
@@petrokemikal G'day, You're not wrong..., but there's a LOT more than that wrong with the idea. Check my earlier reply To see why... Have a good one... Stay safe. ;-p Ciao !
We are still working it out but hope to have more info out soon. For a more detailed description of the motors please see "Why do girls prefer hang-glider pilots" on the same channel.
We are still working on getting a few extra lb thrust and we feel we are almost there but maybe we will just be stuck in ground effect. We know that two Predator motors got us straight up to 100ft from a small suburban park :)
Of course with a tiny bit of lift the 11kg motors make a huge difference. We can climb to 100 feet on a day that is too light to even sustain lift without the motors. On those, coastal, days when you are getting a measly 8kn breeze. Not quite enough to stay up otherwise.
We are still working it out but hope to have more info out soon. We think somewhere in the 1500USD range For more details of the motors please see description in "Why do girls prefer hang-glider pilots" on the same channel

YUP! 1970 baby! My feet first left the ground in the summer of love, 1969.☮ 55 years later, after a marriage, house, kid, dead kid, divorce, and I am still flying! I love every minute of airtime I can get! I have Aviation Induced Divorce Syndrome... AIDS for short.😂 A suggestion. Mount two ducted fan motors. one on each down tube. This will lower your thrust line. They are pricey. About 300. bucks apiece+ batteries etc, but each fan has an output of 8.6kg that will give you a total of 17.2kg/37.9 lbs. of thrust.
Dang - you beat me! I did my first course in the UK in 1973 but kept moving to jobs abroad - trying intermittently to fly. Always had a thing about HGing though...
Nice alternative to the IC pods . You guys in WA? Would love to look into Hang Gliding once I get sorted with gliding. Got some good spots here in Geraldton.

@@robertberndes7878 read that, makes sense. Well I hope you make details available, or sell the electronics+housing kit with suggestion of batteries and engine...
The early hang glider power units in the late 70s (like the Soarmaster) were fitted to the frame. However if you get into a negative g situation (straps go loose, so the pilot no longer has pitch control) then the high thrust line will push the glider over into a tumble. It's much safer to attach the power unit to the hanging mass, i.e the pilot. This is why they stopped making them like this and Mosquito, Wasp, Doodlebug etc, as well as every weight shift microlight trike always has the thrust on the pilot (or trike), not on the wing. The e-help is a great modern example of an electric power unit on the pilot.
With low amounts of thrust and smooth coastal air then you'll get away with this like they did in the late 70s, but if you get tempted to start putting more thrust on it or flying it in spicier air then it could get dangerous.
We are aware of these old dangerous configurations with heavy powerful motors and we have tried many different configurations over many years, for example: one motor on the nose, two motors either side of the pilot, etc. but we were thrilled when we tried the motor at the current position because for the first time we found no change in pitch control, on a low performance HG, once flying. This is due to the line of thrust being opposite to the centre of drag for low performance hang gliders (look at the billow, dihedral, and angle of attack, at trim, for low performance hang gliders). Also, these units are generally very low power and just extend to abilities of a low performance hang glider to act more like a high performance hang glider in so far as its ability to jump from hill to hill along the coast, for example and also to fly in conditions that are too light for normal flight. Also, the position of the prop is very safe and the static balance is perfect. We love them and have been using them for many years now.
@@robertberndes7878 as long as you're aware then I agree that sounds reasonable. It's just that it's always tempting to add bigger motors and more power and start using in more situations! At some point that would become dangerous. Although with electric there is the possibility to have a system using accelerometers to automatically kill the power if the wing becomes unloaded, which wasn't an option for those early pioneers. Although if you start to rely on that as a safety critical feature then it would need a really high level of reliability.
@@robertberndes7878 I can see this useful in situations to get launched in areas where access to a launch has been lost , or due to terrain that makes difficulty launching.
Simply launching on the beach and flying up to the lift, might be preferable to a multi person wire launch on a precarious cliff edge.
I was skeptical about the high thrust line , but given low power applications , and using in smooth marine air, I think it could be used safely.
there could be a easy solutions to fix this conundrum. I have several ideas that could revolutionize hanggliding. I'm trying to contact different manufacturers for a collab.
you could simply put a motor on each side strut (instead of side wires). Side struts instead of side wires should be generalized in free flight hanggliding by now. The philosophical design approach to current HG is not the correct one. Sure light weight is important, but it needs to be put in context of other considerations.
I can’t stand being outside without sunglasses, and wear really well fitting safety glasses when I’m on my motorcycle to keep the wind out of my eyes. How you are out there flying around in the bright sky, wind blasting in your face and no eye protection baffles me. Love the concept though! I am a remote control pilot and love slope soaring , I have a few powered gliders too.
Sunlight doesn't bother most people. We actually like it. You might have a condition that prevents your irises from contracting in bright light, so you have to wear sunglasses when you're outside in the sun otherwise the bright light is painful for you. For most people it isn't a problem.
Excellent, guys! I built a working hang glider when I was going to tech school in Phoenix, AZ back in '72. Bedsheets, bamboo carpet poles, and nylon twine. Drew it on a napkin and built it once I had the materials. It got me off the ground for about a minute before a gust told it to fold on me. School got busier about then and I never did go back to it. Fond memories seeing you fly them so easily. xox Curious of the cost nowadays, especially for a powered version.
That's great mate. You are a legend! It's great when people bring their dreams to life.
@@robertberndes7878 did the motor position pitch the glider downwards??
The mosquito motor kit puts the motor next to the feet to avoid pitching the glider but i want to know if you had any problems with this position of the motor
Did the same thing, in the same place, at about the same time! Got scrap bamboo from carpet shops, plastic sheet and reinforced strapping tape. Drove over towards Tempe and flew it off those little buttes just north of the Salt River. Our kite lasted for about one afternoon of ground skimming. Almost set my butt down on a barrel cactus. Latter I bought a old style "Lark" rogallo wing for about $500 and would drive up to fly the cinder cones east of Flag. God, even today's lowest-performance gliders would have been freakin' amazing back then!
Looks awesome- tons of fun and locally too, great videos!
you guys look like you are straight out of the 70's, when i used to fly....around Sydney.
Oldies but goodies :)
Very Kool Rob, love the latest design nice video mate👍
BEEN FLYING RC OFF THE BEACH FOR 40 YEARS! SMOOTH AIR WHEN OFF THE OCEAN OR DOWN THE BEACH!, STARTING FLYING ELECTRIC IN 1988! THANKS FOR SHARING. HAD THREE HANG GLIDERS AND NEVER FLEW THEM. MY LOSS.
for more thrust, fix a tapered duct on the upright around the propelers
That wa incredible...
God job...
Well done...
Thought for second you couldn't get back up wind. I fly wills wing Falcon 4 , been trying to figure out a way to do this. Off the king post... brilliant.
I used to fly a Wasp Falcon 4 in '79 :) I'm guessing yours is a newer version?
u guys make it look so easy
We love it :)
This brought back some memories, I learned to fly in WA back in the early 90's. Good times.
We truly couldn't care any less.. this isn't about when you started
Maybe a metal panel under propeller rotation could be good to prevent problems in case of prop failures . Probably that brushless has low rpm but those props are big enough to penetrate the wing
Yeah, we like the idea of a Kevlar patch glued to the top of the sail. Easy enough to do.
I think it requires about a 12hp motor which gives about the 19kg of the first example to float about forever. What is important is that the distance from the hangpoint where all the tubes meet is as small as possible. It is at this point where crossbars keel hangpoint meet that all the aerodynamics are worked out by the glider and you keep flying or not. You are putting 100kg of weight about 2 meters hanging below so 20kg pushing 50cm above is probably just about ok. The glider dose not care where the push comes from it is up to us to keep this safe so it does not prevent your fundamental control skills being overwhelmed by the motor.
I have a paramotor which gives up to 70Kg thrust but with a Propellor whose center is 50cm from my back and it works fine. Before I instructed on powered trikes with maybe 100kg thrust but then you have a fixed distace bar seperating you from the hangpoint and everything has now changed from hangliding to an aeroplane david
Thanks David, That's a nice description of forces and distances
I think the other thing we have discovered is that the motor should be situated close to the centre of DRAG. The kingpost mount seems to be pretty close to that.
I've flown in my dreams for years. But you guys fly in the daylight! Looks fun.
I can't suggest paragliding strongly enough! I want to fly hang gliders too one day, but I my paraglider harness serves double duty as a backpack for the wing, so I just keep the whole thing in the trunk of my car and fly after work! Seagulls are totally fine sharing the air with me over the ocean cliffs. It's the least expensive form of aviation! Just look up a school and get good training. I dreamed of flying paragliders for 20 years before I finally did it, and it's better than I imagined. I want everyone to fly!
Lucid dreaming unaided gliding FTW!
Brilliant idea
where do you store the batteries and what's the specs for the batteries, motor and propeller?
In a pouch on the chest or for the big motor a safety break away board mounted on the outside of the chest
There is so much potential on this, it's insane! Install a self stick solar film on the back of the Hangglider and you have a fully solar powered Glider. Look at the SunSeeker solar sail plane, much heavier, smaller square meter, still works. I want it so bad.
Cool idea :)
Watts from solar panel on wings? One would need very large wings, like 10,000 ft^2.
@@JT-cf7dq1m2 will bring about 20W average. With direct sun lot more. Foils bring up to 10%. How much area does a glider have? Lets say 7m2.
Thats about 140W. Not much but the battery wont dry up so fast.
If the solar foil doesnt bring a negative effect to areodynamics that idea could work.
Over time the material will be better. Maybe in 5-10years it will be practical, maybe sooner maybe even today.
Who will find out and make a cool youtube video about it?
I agree with Avian's comment below - this needs some kind of cutoff so that if the AoA goes below the horizontal it cuts out no matter what.
Food for thought...
You'll want a pusher prop at your feet. So the harness is like a power pod.
Love the Aussie hip-hop

Mi sono iscritto! Ciao from Sardinia! 😁👋👋👋
any thoughts about how this might be used along with a ballistic parachute? Very cool project, and the filming was great. I miss WA coastline.
Should be no problem. Leaves the parachute pouch free for batteries too.
what kind of electric motor did you. use? brand? thanks for input
So my take away.
The 19kg is maginal for self launch on flat.
The others seem like a get out jail free card if get to far from a safe landing area.
Winch stuff is pretty cool, either they overloading the winch, or not getting enough AOA on launch for a big climb out.
Yeah, that's pretty accurate although we still have to test the 19lb again we don't know if we are just in ground effect in a nil lift situation. We have increased the thrust by going with slightly higher voltage and may be around the 23lb mark now. Still have to try again on level ground, no lift situation.
19kg 23kg not lb! Sorry
Does anyone know how much something like this cost especially the one with the electric motor?
We think somewhere around 1500 USD but we are still working it out.

Very cool.
How much does the more powerful one weigh? Does it have enough power to take off on flat land?
Very light... The batteries are the heavy bit. How ever many of them you want to carry... The motor weighs less than a kg.
We have only been in ground effect continuously but have now upped the power by increasing the voltage and going for 3 props over two but we haven't yet tested the new configuration. There will be a video as soon as we do :)
The next video will show the original two motor configuration which took off from the ground and climbed straight up with plenty of power. Look out for that one :)
❤ amazing How much power does the motor on this plane have?
Any data how much it costs to fly for example 100 kms? Regarding electricity to charge battery? It would be awesome to get to work in such thing, lol
One of the best things about gliding? The QUIET.
Getting away from all the noise, from traffic, neighbours, HP ringtones and crap labelled as music

Cheers, excellent work, great flights!
Alot of potential!
Have you experimented w/ mounting positions and thrust direction? I'm thinking a reversed (pusher) thrust mounted on the keel boom might be a better position. You seem to have experienced no control issues. Electric propulsion is certainly the future of motive power, we just need battery tech to up its game and we could be flying quietly into said future.

WA?
Yep!
Thrust is lower than is necessary. You can use larger prop and get more thrust. Your goal is to get to self launch, or only as sustainer?
Only sustain. There is a size limitation between the wires and the sail. We really enjoy the advantage it gives us otherwise we wouldn't bother of course :)
Where the battery is located? What is the total weight of the power unit?
Usually on the chest for easy access. 7kg
Very creative design.

Besides that looking awesome, it looked like you were near the Rockingham grain terminal at one point. 🤷♂️
So just incase you know🤔
Can you tell me how high it is....I’ve wondered for ages as I can clearly see it from Halls Head beach?
Hmmm. Don't know but you got the location right :) Crazy that you can see it from there. Of course it could be worked out knowing the distance you are from it and the amount you can see of it. (eg. half way up) and knowing the horizon is 16nautical miles but I'm sure none of that is very helpful :) I'll ask.
If your going to put a motor on it make it big enough to take off with otherwise you get tired of messing around with it.

Of what use is a baby?
We can fly on days when we would be otherwise sitting and complaining.
@@robertberndes7878 I'm suggesting big things have small beginnings.
exceptional.
Looking like you’re basically having a little extra flight to get out of a hard spot but nothing yet to take off from flat land and climb to thermal altitude. Very cool but I think you’re going to need closer to 40-50 kg of thrust to be a real option. Then of course the extra weight of battery and where to place it.
That's right and that is enough for most of what we do. We are more interested in a helper motor because it is easy, light and hardly noticeable when not in use.
For total flight autonomy we know that with two predator motors at 19lb thrust each (17kg total) either side of the pilot - we climbed to 100ft easily from flat ground. We feel that we are almost there with that model but until we are out of ground effect we cant say for sure and yes, there is a lot more weight with the bigger motor.
Oops 19kg not lb! Sorry. So 38kg can get you up from flat ground but that was a long time ago so we are a bit fuzzy on the details. The props were much bigger - 28inch and the original one used motorbike 12v, lead acid batteries strapped to the pilots back!
Like where you’re working the lift from the building. Cool to be taking off from low hills without having to jump off of mountains,eliminating a lot of stress. How long does the battery last? What’s the price of the motor
That is one of our biggest goals with the project. A lot of hills are not accessible as you know and starting off on a low primary dune or hill is a great way to avoid a long difficult hike carrying a glider.
For a more detailed description of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
Battery time varies with use, and size, of battery pack and motor configuration. As a guide though, with our smaller helper motors, we can use them intermittently for hours or, with the 12Ahr pack - full revs for 12min. It really just depends on how many batteries you want to carry around. We get a lot of fun out of a small light pack and that is usually our preference. We often have another charged pack on standby but rarely end up using it.
looks great fun
Why did you choose hang gliding instead of paragliding?
Statistically safer and also much more versatile
New tech looking promising, not so sure about the rap misic though!
This could be the answer for Teewah!
very nice
how do you control the gas ?
Finger control - as can be seen in "Why do girls prefer hang-glider pilots" on the same channel.
amazing
4:29 umm isn't that like really unsafe?
We have a battery release/disconnect system.
Just that little extra lift at the right time would greatly extend most flights. A missed thermal on a cross country flight results in a lot of walking and difficulty.
Those motors look like they're right at the threshold of being enough, so I'm guessing the rest comes from slope soaring? Yet it seems enough to help keep in that pocket of upward moving air.
Although it'd be funny to see this setup used at one of those Red Bull Flugtag events. (If the conditions were right. Instead of diving into the drink, actually having a real chance of flying off.)
Yeah they are there to extend the usual flight envelope to be able to fly on a day that would normally be unflyable, for example.
What about modifying an electric or even gas paramotor setup to yours? Seems like that would be more in line with the amount of thrust you'll need.
We have tried lots of things. Working on a video showing that...
Would love to see ducted fan motors on the outsides of the steering bar with battery built into the steering bar..
G'day,
Well then, either look at History,
Or
Think it through....(!).
Rogallo Hang-Gliders are
Controlled by
WEIGHT SHIFT.
The Pilot is an
Intelligent
Pendulum,
Hanging from the
Theoretical Centre of Pressure of the Aerofoil...
Control in Pitch and
Roll is effected by using the
A-Frame as
Leverage,
With which to change the
Wing's
ATTITUDE
Relative to the
Pendulum's
Suspension Harness -
Which itself points to the
Vector from which
"Gravity" or Change in Angular Momentum is pulling the
Pendulum.
Therefore,
Thus, and
Because...,
ANY
Thrust applied to
Either the
King-Post (as shown here) or to the
A-Frame's bottom
Corners, as ye enthusiastically hypothesise
WILL impart a
Pitching-Moment,
Proportional to Thrust and
Leverage.
This thing has 19 Kg of Thrust about half a metre above the Wing, with a Metre or 1.2 Metres worth of A-Frame "height" below the Wing.
So the 75 Kg - 90 Kg Pilot has a 2.1 : 1 Leverage Advantage over a Pitch-Input one quarter that of how much Weight he can shift.
So....., this is barely sufficiently powerful as to be safe to take of into ABSOLUTELY Still Air - but it's too gutless to be safe in Wind, Turbulence, or patches of Sink ; and adding enough Power to be safe-ish to fly would mean doubling the Thrust at minimum - tripling it would be much better - but then the Pitchdown would be impossible to correct for with Weight-Shift.
So, it's a tantalysing
Dud.
Not worth doing.
Historically, go looking for the Film Clip from the mid 1970s featuring the Lunatic who strapped a Propane Bottle to his Backpack, feeding a pair of 40-pound Thrust Gas-Jets mounted at the bottom Corners of the A-Frame of his 90-Degree Nose-Angle Rogallo...; and had the boundless Optimism required to launch himself off a Hilltop into the Wind with both Jets running at full-blast.
Wearing Jeans and a T-Shirt, with an open-face motorcycle Skid-Lid for Crash-Protection......
It took off, and tried to climb-out at a 45° Angle as he desperately attempted to pull himself up level with the Bar..., Vainly struggling to lower the Nose - but of course it stalled, fell down, broke and collapsed onto him - and then the Dacron on the hot Jetpipes melted, and ignited, and shrunk down onto him as well..., burning him horribly.
He was lucky indeed, the theory goes, that his Propane Backpack didn't go all B.L.E.V.E on him...
So, no.
Pushiness, or Pulliness, on a Rogallo...
MUST be precisely
Aligned
THROUGH the
Wing's Centre of
DRAG.
When Aerotowing Hangies, we used a Bridle from a Tube extending the Fin-Post of the Tug to a Release-Hook on the Tailwheel Spring with a Steel "Bull Ring" sliding freely in the Bridle tied onto the Towrope and a (2-G) Weak-Link from Bridle to Tow Release..., thus the Towrope Loads go from the "Bull-Ring" to the (Pusher) Engine's Thrust-Line which is halfway between the top and bottom of the Bridle. And the Bull Ring slides up or down to adjust for Formation-Keeping difficulties.
At the other end of the Towrope another Bull Ring pulls on another Bridle, one end attached to the Apex of the A-Frame (pulling against the Wing's Weight & Drag) with a Bowden-Cable Release attaching to a 1-G Weak Link, and the other end of the Bridle joining the Pilot's Harness via a Slip-Knot, pulling against the Pilot's Weight and Drag.
If you want to get deep into the subject, then feel free to backtrack me to my
"Personal Aeroplanology..."
Playlist, therein to find and enjoy,
"Aerotow Launching Rogallo Hang-Gliders...; Development & Implementation Of The Lockout Index !"
Back in the mid 1990s I had quite a bit to do with Aerotowing Rogallos, and some Ultralight Sailplanes too.
Have fun,
Stay safe.

Ciao !
@@WarblesOnALot Man, I HATE a know-it-all! 😁
That was a great explanation, obviously you know your stuff. We have hang-gliders here on the Monterey peninsula, but I've never seen a motorized one locally. I just wonder how far one with a mid-sized motor and decent pilot could get if they were trying - use the motor to gain altitude or find a thermal and then shut it off till needed again. I envision hundreds of miles, but that's just me.. Would it be worthwhile to create such a competition? (Hint...)
@@thesoundsmith
G'day,
Ah, well, yeah...; I aim to function at the level of a Competant Smartarse (!), because such is tolerable - it's really only the incompetent ones that people can't stand...
Well, in 1978 a Brit. named Robin Cook flew the first "Microlight", as they called them in the UK back then, across the English Channel using a 10 Hp McCulloch Chainsaw Motor atop a "Stick"projecting above the Wing...; on a VJ-23e "Swinging", a Foot-launched Aerodynamically-controlled Hang Glider with Plywood Spar and Foam Ribs in a Cantilever Wing on an Aluminium Fuselage-Tube supporting the Cruciform Tail with Fins, Rudder, Stabilisor and Elevators, at one end and the Wings and Hang-Cage at the other - featuring Parallel Bars and a Swing-Seat with a Hang-Harness...; all 3 Control Axes were managed with a single Side-Stick on the Righthand side.
The VJ-23 Swingwing was Volmer Jensen's outraged response to the early Rogallos which struggled to achieve 4:1 L/D...; whereas the VJ-11, a Biplane Hang Glider Volmer had been selling Plans for since 1948 achieved 6:1..., and so the VJ-23 Swingwing beat the snot out of every Rogallo around, in '73 or so, with a L/D of 9:1.
Jensen had motorised the Swingwing in 1976 - after hearing of Macready putting a Chainsaw Motor on his Icarus (Tail-less Swept-Wing Hang Glider, with Drag Rudders at the Tips, hinged on the outer rear Interplane Struts...) in 1975 - the first half of the Year, I'm guessing...; and by December 1975 Ron Wheeler at Waverley in Sydney had failed to take-off in a Victa-120 Lawnmower Motor on a Tweetie (Foot-Launched Aerodynamically-controlled Hang Glider featuring Sailboat Masts for Fuselage Tube and Leading-Edge Spars, Single-Surface Wing-Skins with a Bolt-Rope hemmed into the Luff-Edge and thus secured in the Sail-Track on the Mast..., all Cable-braced with the Skins drum-tight and Cambered Battens made of bent 1/2-inch Aluminium Tubing sewn into Pockets in the Wing-Skins..., with an A-Frame for the Pilot in a Hang-Harness using Weight-Shift for Roll Control and All-Flying Stabilators and Finless Rudder driving Pitch and Yaw from a Righthand Side-Stick...)
Wheeler had added Wheels to the bottom of the A-Frame, and a Plastic Seat, with Elevator and Rudder now on a central Joystick.
The 2nd Prototype "Skycraft Scout" again had a Victa 120 - tagged a "Pixie Minor" 8 Hp Motor ; but with a 3:1 Bicycle-Chain Reduction-Drive, it did fly, at Sea Level, in October or November 1975.
Then when the Dep't of Transport let Wheeler know that if they heard of it flying again he would be prosecuted, he responded by inviting them to inspect his doings, observe what it could do, and then say WHY he should be prevented from playing such harmless Sillybuggars for the fun of it.
So in January the DOT showed up, and,
"The 8-Hp, 1975, Red Baron Skycraft Scout ;...."
was duly demonstrated to the Beaurocrats, who laughed so hard they went back to Canberra and in August 1976 Air Navigation Order 95.10, which had been written around the 3rd Prototype Scout, was gazetted - exempting ALL such "Minimum Aircraft" as defined (MTOW 400 Pounds...) from ALL OTHER Air Navigation Orders - subject to provisions (Not to exceed 300 ft above Terrain, not to cross paved Roads, not to overfly Municipal Areas, Race-Meetings, Public Gatherings or Regattas, not to come within 500 ft Vertically or 1,000 ft Horizontally of any Cloud, not to approach ANY Licenced Airport or Controlled Airspace closer than 5 miles..., and Aerobatics of any kind were VERBOTEN.
Which is why the rest of that Movie Title is,
"...; World's 1st Legal Minimum Aircraft !"
It wasn't till about 1982 that the US brought in their FAR covering Ultralights - basically a copy of ANO-95.10...; so, for a while there Oz was leading the Revolt against Lycosaurus powered Cabin Spamcans on Training-Wheels, flying on Autopilot or trying to fly like an Autopilot...,
The FIRST Rogallo with an A-Frame instead of Parallel Bars was built by John Dickenson, of Grafton NSW, Oz, in 1963...; Bill Moyes was the first to fly it, but he didn't think it up, or build it (!).
Anyway, because the VJ-23 was a pain in the bum to build, the tapered Wingplan meaning no two Ribs in one Wing were the same size or shape, and the 36-ft span Wing was one-piece and a pain to transport, and Aluminim/Foam/Resin/Wood was beyond a lot of Scratch-builders anyway.
So Jensen started again and in '78 the VJ-24 Sunfun appeared, with the same Span, Aerofoil, and L/D - but the rectangular Wingplan meant ALL the Wingribs are identical, and the whole Airframe is pop-riveted Aluminium, fabric covered ; and the Wings are built separately and bolted to the Fuselage-Boom Tube, braced by Lift-Struts off the Hang-Cage.
I was the third owner of the Red Baron Scout..., if you check out,
"National Transportation Museum ; Visiting My First Aeroplane !"
you can see my "pilgrimage" to visit it last year (shortly before starting treatment for Stage-4 Tonsil Cancer....; which was tough but it worked - though when I made the Video I was half expecting to be on the Daisy Up-Pushing Brigade by September.).
My VJ-24w is a bit of a rarity, I meddled with the Design of the Trailing Edge and Undercarraige while a friend was scratch-building it..., then I bought the Project after he'd started on a 24, modified it to 24e (engine) standard for a 10 Hp McCulloch in the Hang Cage, then gone to a 24w (wheels) version with my idea of a (Bungee-sprung Floating-Axle) Undercarraige, and he put a 22 Hp JPX Pul-425 on it rather than a 15 hp Yamaha stipulated by Volmer.
When I got it I redesigned and rebuilt the Wing Leading Edge in Sheet Aluminium replacing the original 1.5mm Foam Styrene and Dacron and Resin "1/2 Sandwich Shell"...; and then it got my idea of an actually streamlined Pod, a Spring-deployed Parachute BRS, and a panel of Instruments.
Thus, when it came time to Test Fly it, nobody had any better idea than me as to what it might be likely to do, and it was my Pop-Rivetry & I designed and carved the Propeller, too.
So I have actually made the First Flight on one genuine (Mystery Bag) New Prototype...
And it took me 3 months to rack up 6 hours and be happy with the Flight-Test Program ; and after another half an hour in the logbook - guess which Dickhead agreed to a Downwind Take-off attempt in a 200 yd Paddock, with an Ultralight Motorglider (!) ?
That was a day when my
Smartarsery
All came
Unglued
At once...
lol...!
So, yeah, if you can stand the Hillbilly production values (?) then you might enjoy scrolling around in my "Personal Aeroplanology" Playlist ; because the stories are pretty good, and I try very hard to not be wrong.
I think my Bullshit Content hovers around 5% ; but I never know if that means I'm 5% wrong about EVERYTHING - or if 19 times out of 20 I'm totally correct an the next opinion I hold will be utter Bullshit...(?), so all I can do is to keep trying to get shit right (!).
I think the most successful Powerpack conversions for Rogallos had the Motor and Fuel on the Keel, Fuel ahead and Motor behind the A-Frame, with a Propeller at the back of the Keel, shaft-driven, with 2 Skids poking down to protect the Prop.-Tips.
Why not put the LiPo's
Up near the Nose,
Balancing a Motor
Down behind your
Toes...
Where
The Prop. won't chop 'em off
When for Landing ye
Flare...?
To be safe you need to be able to climb at 250 Ft./Min., and the Thrust MUST be aligned with the Drag.
But a Motor and Battery out of a serious Electric Chainsaw should make a Rogallo go uphill...(?) - and if not then gutting an Electric Motorcyle should go very well indeed.
I hope to thus Electrificate the old Jensen, one day (!).
Have a good one.
Stay safe.
;-p
Ciao !
Ducted fan motors are not as efficient at making thrust, so much so that to get the equivalent thrust of 19kg seen here, the battery's would be toast in half the time, not to mention the noise would be immense due to the high rpm...

Is 19kg thrust really enough to climb with? Awesome setup guys
We are still working on getting a few extra lb thrust and we feel we are almost there but maybe we will just be stuck in ground effect. We know that two Predator motors got us straight up to 100ft from a small suburban park :)
For a more detailed description of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
Of course with a tiny bit of lift the 11kg motors make a huge difference. We can climb to 100 feet on a day that is too light to even sustain lift without the motors. On those, coastal, days when you are getting a measly 8kn breeze. Not quite enough to stay up otherwise.
What size predator motors ?
very cool, nice relaxing vibe.

These hang gliders need to be able to extend and retract the wing area depending on wind conditions...maybe winglets...
@Robert Berndes Hi. Nice setup, what is the "flight time"? How strong is the motor (kw)? and what battery are you using. Thanks.
LiPo's. Lots more info in the description of "Why do girls prefer hang glider pilots". Cheers :)
What motor, propeller and battery are you using?
too many combo's to mention but we hope to have some more info out soon.

Sorry - you ruined it with music. Any updates, though?
YUP! 1970 baby! My feet first left the ground in the summer of love, 1969.☮ 55 years later, after a marriage, house, kid, dead kid, divorce, and I am still flying! I love every minute of airtime I can get! I have Aviation Induced Divorce Syndrome...
AIDS for short.😂 A suggestion. Mount two ducted fan motors. one on each down tube. This will lower your thrust line. They are pricey. About 300. bucks apiece+ batteries etc, but each fan has an output of 8.6kg that will give you a total of 17.2kg/37.9 lbs. of thrust.
Dang - you beat me! I did my first course in the UK in 1973 but kept moving to jobs abroad - trying intermittently to fly. Always had a thing about HGing though...
Wheres the battery
For more details of the of the motors please see the description in "Why do girls prefer hang-glider pilots" on the same channel.
In one model the batteries are in the pod itself with a manual disconnect. For the others the batteries are on the chest for easy access.
@@robertberndes7878 thanks matey...
I just found out about this, why isn’t every hang glider electric?
Very cool ..!
Nice alternative to the IC pods . You guys in WA? Would love to look into Hang Gliding once I get sorted with gliding. Got some good spots here in Geraldton.
Nice one mate :) Sure are.
Bit of Gero footage in the other video. Red dirt, green grass and blue sky.

@@robertberndes7878 cheers mate, not sure if there's many flying up here anymore. Will suss out your other clips.
We usually go up one a year. By the way, there is a school here in WA run by Dave Drabble. It is in the description of the main videos. Cheers :)
The song is dope. Don't let the other commenters say different.
Thank you! We have had a lot of negative comments but looking at the number of views, it must appeal to a lot people. The song writer is a friend of ours. A young Aussie dude from the country.
Génial !!! C'est le renouveau du Vol Libre

Ok. Go ahead. Take my money ….I’m in. Where can I get one???

Donde puedo comprar uno cuanto cuesta alguien que me allude
Cool!
Спасибо. Приятно видеть. Удачи.
Let us hear the flight - the wind
Brilliant work, hope to see you on a beach some day!
Awesome! Hope to see them on the market soon.
Thank you!
This is awesome, is that some sort of drone engine and power pack? Where can I get one? Do you think that would work well with a Litesport?
We think it is more suited to "floaters" like the Fun, Malibu, Falcon etc.

@@robertberndes7878 read that, makes sense. Well I hope you make details available, or sell the electronics+housing kit with suggestion of batteries and engine...
