I love the visibility and comfort in my DG. I can even scratch my feet.
But I'm glad that there are people like Gozalo who are thinking outside the box.
What a great interview. Seems a totally nice bloke who's thought through the issues. I wish himr all the best in his venture !
🙏
I think it's brilliant. I'd happily give up a 5 or 10 points of L/D for that kind of view. One of the most dangerous aspects of conventional gliders is the blind spot under the nose with the reclined seating. I witnessed a midair between two gliders in 2004, a PW-5 and LS-1 thermaling together just outside the circuit at about 1200 ft, when, after losing track of each other, the PeeWee turned in while ahead and below the LS-1, and the LS-1 never saw PeeWee coming up under his nose until his leading edge was chopping the PeeWee's tail boom off. PW-5 pilot survived because he had no option with his glider spontaneously exploding and just released the harness holding him to part of the fuselage pod and pulled his ripcord as he dropped through the debris. The LS-1 pilot tried to save it with several feet of collapsed leading edge, and ended up diving into the ground after a number of circling/diving maneuvers, which was the end of him.
Field of view is one of my top three priorities in aeroplane and glider design. The more I can see the happier I am
Thanks for the opportunity. Great! and please comment if you see this video. Name of glider: UltraVision.
Thanks again for the interview! And don't read too much into the comments here haha
So cool that you approached the interview with a clear mind. The biggest obstacle would always be that pilots would very rarely pay for a less capable glider, unless it is far cheaper than a new glider. Pilots today get that with used gliders. Having to look down for instruments would also be an issue for most people. I would love to see the current state of the art gliders have just a few more inches of shoulder width. My DG is good in that regard, but in many other gliders I just can't fit into at 6'2" and 220 pounds, but mostly with broad shoulders. He should try flying a DG. I can see directly below in a 30 degree bank, and can usually see a hundred feet under the tow plane on aerotow.
I'm glad that there's a bit of divergent thinking going into glider innovation. It's interesting and might (in some part) lead to an idea that gains more widespread adoption. Or it might not - but I'm glad to see something different to the usual incremental improvements.
Yip, people often forget there's a huge variety of pilots and potential pilots...
Fun fact: In germany they have what's called "Akaflieg". They are groups of aeronautical engineering students from individual German Technical Universities, who design and experiment with aircrafts. Most often then not they work with gliders. That is how famous companies and Manufacturers like Glaser Dirks started.
Designing a high drag fuselage isn't divergent thinking.
I completely agree with Nathansmith7153, in glider design reducing drag is one of the main points. For this reason, the fuselages of modern gliders are as slim as possible. If Gonzale had spent more time in a glider, he would have noticed that the semi-recumbent position was less tiring than a seated position, especially for long periods of flight.
A concept design that will only ever remain thus.
I realy like that Design. Great Designer. Respect. I wish the designer much success in marketing his great idea. I think he appeals to a wide range of interested parties.
I'm intrigued by Gonzalo's design, after flying helicopters something that feels strange and confining getting back in to fixed-wing aircraft is the loss of visibility. I would be more interested in a powered or self-launching version and it appears that enough room in the upper fuselage might be available to accommodate a retractable power plant, or a couple of pusher electric motors might be worth considering. I would be interested in knowing more about rudder pedal design and what the propensity for nose-over might be? Perhaps an extendable nose skid might be possible?
It would be interesting to see a concept through to test flight stage, event a 1/2 scale model. For people with a physical handicap that can be an issue with getting in and out of a traditional glider it may be the difference between flying or not. Im sure we've all watched pilots with buggered knees/hips struggle getting in and out of cockpits. I drive long distance in the trucks as well, it's not an issue with the seating position.. A buggered seat cushion in the Puch gives me a level of discomfort that's not nice after 3 hours.. Lol.
Cheers for the clip Tim.
It seems like this would find more buyers as a twin seat version for training and scenic flights
One issue that I see rn is that the canopy is gonna have a lot of scratches and impact points if you're taking off a grass field. Interesting nonetheless.
Good point!
That is a good point. You could probably rig up some kind of disposable see-through overlays over the vulnerable areas, that could be replaced easily and cheaply. Like Formula 1 drivers use on their race helmet visors
I really like your intervies style....you let the interviewee talk . Very good.. thanks.
Thank you!
I hope they build it so that there would finally be a glider uglier than my PW5. 😅. But the PW5 sure is a joy to rig and fly.
I love how unique this design is, and I'd be really hyped to fly it if it existed.
However, I can't see there being anyone so deep into gliding as to spend hundreds of thousands on a new glider, yet also be willing to sacrifice performance on the thicc cockpit. But I hope I'm wrong because it would be fun if these existed.
Does anyone remember the 'Edgley Optica' aircraft...looks like one huge Fly's Eye
I can see it working in a sort of "fun to fly around for a few flights" sort of way, but I don't think there's enough of an audience of people that would want to own one of these for any sort of series production. Personally I've never had a moment of thinking "gee, I wish I could see more out the front" in basically any glider. Looking that far down is probably a bad idea from a nausea/airsickness point of view anyway.
I also have massive doubts about the ergonomics. Placement of the instruments seems silly at best, way too much movement required to check instruments and the seating position seems a little too upright for long term flying for my liking.
In terms of crash safety, I'm not too worried about impact safety of the glider hitting the ground, but this thing going into a hedge or a fence is a surefire way for the pilot to get gravely injured I think. A "normal" glider has the shape to naturally deflect fence wire and branches (mostly, which is why we sometimes have wire-deflector bars in the canopy). This thing would not offer any kind of protection whatsoever.
My take on this: I'd put a small instrument binacle in the front (a bit like seen on some SG-38 or Slingsby Grasshopper gliders. example ruclips.net/video/kIY8lyl0m_4/видео.html) with the main 3 (alti, ASI, VSI). Things like radio, transponder, etc can be at the sides. Have this instrument pod pedestal hide a reinforcing rib that offers some protection from frontal impact. You're not going to lose much vision from that
Well done. This is the way to have discussions on line.
Interesting video.The upright seating position seems identical to the early training Glider developed in the 1920's ( Alexander Lippisch's ZOGLING Glider 1920's - Pupil ) or RF Dagnall's DAGLING Glider 1930-32 ) This design looks exactly like a modern enclosed composite version of one of those early primary training glider designs. Exactly the same positioning of the tow hook and same C of G as well. According to my reference the Daglings required high maintenance and were not very safe for a Pupil Pilot learning to fly and many accidents occurred. The Dagling Primary Gliders were the only way to learn to fly a Glider before dual- control two-seater gliders were developed and were cheap enough for Glider Clubs to own them. Cheers Paul
Glad you thought it was interesting!
Thanks, well... I did not realised I also have that argumentation line for the hook. Great!
30 flights in, looking down is a novelty. A few hundred hours and a bunch of cross country flights later, when you're now in the market for buying gliders, the novelty has worn off in favour of performance and (hopefully!) meticulous lookout which is predominantly along the horizon.
Great to see something different on the channel. Seating position looks similar to a paraglider , so paraglider pilots converting to gliders would be good people to survey about the difference they perceive. It reminds me of the good points of paraglider visibility wise , but with better protection as compared to almost none except a lot of padding under the backside .
,Hi, The UltraVision flapped 18m flies better than a Discus CS 15m (that it is a bit old model now). With 60Kg/m2 of wingload, you get 200km/h with 2m/s of sink.
@@gonzalogarcia-atance5840Sounds amazing performance .It could catch on !
I Think that the visibility would be cool. Some Aspects that could become a disadvantage:
- With the huge compartment for the Pilot, you need to add a lot of material to have the same strenght/ crash resistance. I would design it the other way round and reduce the opaque surface (like sitting on a crash-beam) to get more stability with less material.
- it`s harder to stand the g-force if you`re in an almost upright position. Maybe the flight will stress you more.
- I cannot imagine how hard it would be to open the canopy against the force of the wind. It would need a rocket-propelled system to open it in a case of emergency.
- If you live in a country with a lot of fences, the wire will cut you to slices in an unlucky outlanding. Tree branches are also a hazard to the pilot. It won`t be easy to add a deflector to that design.
Birdstrike through the canopy, is that potentially thing with gliding?
That is an issue with all gliders, but it's very rare. Most of the time the birds can get out of the way...
You didn't ask my burning question. Is there any possibility of a prototype being built?
I asked that after, not at this stage unless a glider manufacturer takes it on
As a tall pilot, my concern is the upright seat would give even less headroom than I get in a typical glider if it's sized for the average / "one-size-fits-all" pilot. otherwise I love the idea of flying with that view!
Hi, I am 1.93 or 6foot 3inches. The design is therefore for a 2m pilot, as depicted in the renders, the renders are based on a 2m pilot. Thanks
Could always add a Sextant Bubble above the pilot ;-))
As a helicopter pilot, I really like this idea. In fixed wing aircraft the visibility is so bad, that I never wanted to become a fixed wing pilot. I would love to fly one of these gliders.
What's the glide ratio of a helicopter at idle?
@GlidingTobster 3:1 is a good approximation. This glider will have a 46+ glide ratio, according to the designer
I like this glider as it reverts to the more "sit-up and beg" pilot geometry-position of the Ka8 era gliders, which I primarily flew, which gave much better situational awareness when in a thermal with other types. I'm a bit uncertain about having instruments at the side. At the very least one should have the ASI, compass and Altimeter in front of you. Perhaps mounting these on some form of articulated swinging-arm might work? One area that might be a problem is the effects on the pilot of a ground-loop? Another issue may be crash-protection hitting a barbed-wire fence - a flying colleague of mine was pinned by the neck in just such an event and was fortunate not to be badly injured.
Compass? Never used it in a glider, sun is enough to find general direction. ASI, Altimeter and vario are way more important than a compass for a glider pilot in VFR.
@@StratiljirkaI agree - although, it's obviously more important for flying cross-country, and for helping to keep you outside of controlled airspace. Where we flew from that was a major reason for using the compass rather than "by eye" methods for establishing direction.
Brilliant. I grew up at Bowland Forest GC - on my very first flight I remember thinking that I couldn't see down as much as I was expecting or wanted (K13)
I know exactly what you are talking about... I flew in the k13 and could not see very well Parlick and the crest I walked through many times.
I really like that design. As a electro-motorized two-seater it would be a great way for clubs to make a bit of money for offering scenic flights.
Finally a glider for the armchair pilots.
I'll take mine in satin blue Lazy-Boy with the optional beer cooler armrest please.
There's something to that :)
I saw the suggested L/D 46-50.... Only in his dreams!, He would be lucky to get it to around 35-38, with a very steep performance fall at just slightly higher speeds.
46-50, assuming 56 in 18m is true for the current models.
,Hi, The UltraVision flapped 18m flies better than a Discus CS 15m (that it is a bit old model now). With 60Kg/m2 of wingload, you get 200km/h with 2m/s of sink.
@@gonzalogarcia-atance5840The entire polar is much more important than best L/D.
Frankly, I can not believe it (200 km/h 2m/s or LD 50 at slow speeds). However, if you say it is 60 kg/m2, then its like water-ballasted brick. The stall speed of such thing would be around 100 km/h!!! I feel that you miss the point a little bit of what makes a good glider. I am not sure what airfoil you would be using, but the more advanced, competitionlike foils do not have very high Cl, and the stall speed would be even higher, may be 105-110?; a beginner glider airfoil might have a Cl of1.3 and that would give you 100km/h stall. But almost no sane glider pilot would fly such a glider. You would be approaching at 130 km/h, faster than airplanes! Also, the sink rate would be incredible, probably at least 80 cm/sec. Now, if you plan this glider for sight-seeing, it must be easy to fly (=slow, benign ), and with such wing loadings it is only for experts, who would not care much about sight-seeing.@@gonzalogarcia-atance5840
If crash protection is of primary concern, i believe an airbag system would be a far better solution.
Interesting.
I could see ingress/egress being easier for the less athletic.
And the more upright seating position would reduce the CG change.
So great for those overweight elderly glider pilots.
Yeah after hauling some older people in and out of the DG1001 recently, that has some merit!
thinking of weight… why is the seat limit 110kg or less in gliders (at least in the UK)? can we change this
It looks like a famous RC model slope glider called "Le Fish"
it does...
I think the tail-boom would have to be much heavier/stiffer than shown or typical as the lower stabilizer would be subject to high landing loads, particularly in a yaw/groundloop situation. Good job thinking outside the box 👍
Would be a cool design for a foot launch micro lift ultra light glider 🤔
Perhaps, but you loose the cross country performance. It weight 600kg, it has electric selflaunching.
Already done, it is called "Ruppert Archaeopteryx".
Same seating position as the instructor in the Doppelraab glider!
Interesting idea. I like the idea of better forward and down visibility for collision avoidance.
3 points occur immediately:
1. Much easier to enter/leave on ground, and potentially in the air, very desirable for those my age, but canopy ejection?
2. Seems likely to be difficult to prevent premature rotation during winch launch due to cable well below cg.
3, Upright position - glider unlike most aircraft spends long periods at elevated g forces. Effect on pilot?
Not a dissimilar position to an airline pilots seat. They tend to sit there flying for hours on end.
I was used to landing in My Pik 20 b as though standing up when approaching with full 90 degree brake/flap!
Yea I'd worry about dying in a crash. I think the addition of a HUD would make this design pretty cool.
I started to watch Balleka channel this made me want to take up gliding, will try it next year.
Awesome to hear :)
Great interview, and love that Gonzalo is willing to think a bit differently 👍 Never underestimate the attraction of a great view for the pilot - I fly a flexwing microlight, and it's an open cockpit with an unrestricted view - compared to that, the traditional 3 axis planes feel restrictive, and looking through plexiglass windows just doesn't cut it!
Thanks. Main two reasons to fly, to compete or to enjoy the view.
@@gonzalogarcia-atance5840
iff=
-install WHISPER AERO ultrasilent fan...
-involve "weake immersed thrust" ?
-fully transparent fuselage +safety cage.
I don't think you need a radical design like that to improve visibility. For example, the ASK13 has a better view than the ASK21 without being that different. The problem is that performance will always remain a big concern for gliders, and even if you are not a competition pilot, you always want to maximize the chance of not being back on the ground after 5'.
However, I am not saying it wouldn't be fun to fly something like that.
Still you can see a lot of issues there, some of them seriously affecting the safety of the flight... Like not having your analog instruments in front of you! I don't think FAA or EASA will like that. So no, I don't believe it will be a success 😅
Like a Bell 47 G. Good for vision and fun.
Of course you could also design one where the pilot lays on his belly with a clear (reenforced) nose... in a semi-reclined head up position...
Never die in an fugly glider
Interesting design. Probably not for competition pilots, but more for the “Fun-To-Fly” pilots.
Ex Paraglider pilots will feel at home in the sitting position and also the good visibility, and with 5 times better L/D than a Paraglider, what’s not to like! 😁
I am a former paraglider pilot with lots of experience, switched to gliding a decade back. You get used very quickly to the new position, after a few hours you don't miss the low performance of a paraglider. From time to time I go for a paragliding flight, it is nice but I know where I am at home.
I just don’t see this concept working because I don’t know any glider pilot who has the priority to be able to see forward. To really appreciate the view, one would have to spend their time low down polishing a ridge because as soon as you get over 2,000’ above the ground, there’s not much to appreciate unless in the high mountains. Maybe this is the sort of glider to borrow for a day of low flying fun in the mountains? However, for a glider pilot to spend £100,000 or so to replace their aging Ventus, ASW20, or ASG27, I don’t think so…
Being a realistic optomist the first thing I was concerned with was bailing out in an unrecoverable situation.That is a very large lump of perspex to shove out of the way,unless there is a method that enables the pilot to drop through the floor of the glider seat and all and be secure enough for normal flight..................................
But when that happens by accident.... :(
Wish you asked about his next steps in realizing this design.
He did... too long interview already... blame RUclips algorithm.... The answer was a bit evasive...
Very interesting and he has potential. I have two distracting comments regarding the design. 1) the cockpit with the excessive drop will not help the pilot in a stall spin accident. 2) I would be concerned with control in a sideslip situation from the sudden increase of extra drag from the nose. Now if this would be a two seater design, this might have potential for high performance training and sight seeing.
Thanks, perhaps a detachable cockpit in case of spin crash... so if the cockpit is subjected to lets say 20g in a 45 pitch down... it detaches from the rest of the aircraft, at the same time the seat deforms to absorve the energy of the impact, while the legs are not so important. Just ideas at this stage.
OMG!!! that guy is a genius!! ....and he is so handsome.... lol😂
😂
Hi Tim, you have great videos and I have watched all of them, though this is not one of those ;) This concept has several flaws. Sorry for contacting you this way but I didn’t find an email or any other channel to contact you. I want to buy a glider and I would like to have more information before taking the decision. Information is not readily available on the internet, so maybe a RUclipsr has more chances to give me an informed opinion. My ideal glider is a electric TMG, that doesn’t need a wing runner, it has at least 1h autonomy after launching, it’s certified and it’s easy to rig and put in a trailer. I know that it doesn’t exist, so my question is what’s in the market that it’s a close match to my needs? My priorities are self launcher without wing runner, glide ratio, low cost of maintenance and autonomy. Being electric in a TMG is a nice to have, but mandatory in a “normal” glider. 2 seater is a nice to have, but not mandatory. The certification is very important, because many airfields in my area don’t allow ULMs. My 3 top options are a Stemme S10 VT, a Dimona and a Phoenix U15, but a spark of hope hit me yesterday when I saw a video of an electric Antares to launch without a wing runner.
Hi thanks for watching! Unfortunately electric self launching is very new, so there aren't many options. Have you looked at the Pipstrel? They now have an electric self launching Taurus glider: www.pipistrel-aircraft.com/products/taurus-electro/
@@PureGlide I know Taurus, but there are too many in the used market with low hours and not so many years. Which makes me think that there must be some serious issue if owners are willing to sell it not long after buying it. The Phoenix, for instance, you cannot find any in the second hand market and when they show up are usually sold very quickly.
Looking at this in a completely different way, quiet observation platforms could make very good use of this type of glider. "Drones" of all types make a lot of noise and are easily detectable from their noisy propulsion systems. This would be silent by comparison.
And it may have stall issues due to the position of the horizontal empennage. Eyeballing it, it looks like it will be just in the shadow of turbulent flow at close to critical angles of attack. This is not something we like in gliders, because we often fly very close to stall speed. So unstable behaviour at these speeds is not welcomed at all. I would put the stabilizer much lower, around the fuse; this was quite a common design feature of older gliders before T-tail came en vogue
Yes, this is something to be checked, but it is so easy to solve as moving the horizontal tail position. The Perlan glider that flies continously at almost stall speed has the horizontal tail in a similar position as the UltraVision. Probably it helps to identify stall for bufetting, making it safer.
@@gonzalogarcia-atance5840 If you correctly select the position, then yes, if it buffets all the time way before the stall, then that is very tiresome. But yes, you could probqbly move it without majour hassle, I probably owuld think to put it at the fuse level. Just looked at the Perlan glider; no, the stabilizer is much lower and it would not be affected by the wing wash at stall angles.
The only advantage I see in the concept is that you can probably pee better than in a lying position.
if you are going to sacrifice the design for visibility, just have a normal layout but more canopy or even porthole windows. A little more nose height and length and width and you can lower the canopy rails, lower the control panel, and put the pilot a bit farther forward under the canopy, and boom way more visibility without a huge droopy nose
Perhaps, but my point is that you have a 40 degrees down visibility, you see what you fly over. Also, I wanted to make clear the concept, a cockpit that looks not well developed or optimised does not bring the point I wanted to make. My point is a change of paradigm, maximise visibility, maximise flying experience, do not compromise these points for performance.
To paraphrase Marcel Dassault, a beautiful glider is a glider that flies well. Before watching the video I thought it was an April Fool's joke or a cartoon glider. But to be honest I started flying in the 80s, among others on the Falconet. It wasn't the most beautiful glider but I've never been better known for spiraling in poor weather conditions...
Danger ! Your bumper is you face !
I have lower back issues. I have a 2hr limit in a Ka6 but 6hrs in an ASW 20 was not a problem. The upright position would not work well for me. Interesting design though and looks like it would be fun to fly.
I think there is some bad things about the design.
Tow point is much below center of gravity and center of lift. It will always pitch up during tow.
Would be difficult to hold the wing straight by hand for the take off, because it would be higher.
How do you eject the canopy if the relative wind is pushing it into the glider. If you need to jump out. I know it doesn't happen often but it is a safety feature.
Front crash protection is really bad, if you crash in trees or fence...
I think it would have been better to just make the front of a normal glider a bit more transparent.
Or make a glider with the pilot position of a hang glider.
little guppy glider
Maybe a little extreme, but somewhere in between would be great for me.
I set my case.
The lack of pitch reference and the upright seating position would make PIOs very eady to get into.
Pitch reference can be added with a bit of tape in the canopy. Thanks.
I think one will get used to it.... Unless it wer the first and last flight
This is a great idea, if you are not interested in competition, performance is not the only important thing. If you want to maximize your flying experience and don't care about performance (compared to a sailplane) try paragliding.
10:27 ... interesting ideea...🍺🍺🍺🍺🍺🙄
I figured you would talk about this one lol. It does seem like fun but it wouldn’t be very good at all for soaring.
,Hi, The UltraVision flapped 18m flies better than a Discus CS 15m (that it is a bit old model now). With 60Kg/m2 of wingload, you get 200km/h with 2m/s of sink.
Wish you all the best with your unconventional design.
He may get a high LD ratio for slow flight, but at higher speeds the performance would be abysmal due to fuse drag, (Fuse drag behaves more like speed squared). Second problem could be the hook-up point which is way down, so there would be a pitching moment during tow. I have some 200 hours on LS4, but I must say that the down-front visibility really bothers me. I flew a few timeson SF 25, and I loved the much better view during landings. Also, I do find semi-upright seating much better. But there is no way this design will fly well. It will be something of an ASK-13
,Hi, The UltraVision flapped 18m flies better than a Discus CS 15m (that it is a bit old model now with shorter span and no flaps). With 60Kg/m2 of wingload, you get 200km/h with 2m/s of sink.
All drag is speed squared.
@@nathansmith7153 and height lose is cubic speed... like in any other glider.
This is intended to be a high performance single seater, but wouldn’t this make more sense as a mid performance two seater that clubs can use for experience flights? The kind of private owner who might want this enhanced visibility might be more inclined to fly with a friend, and I’m honestly not convinced there’s a large market for private ownership of a glider like this.
Definitely get a better view and easier to get in and out of.
Not sure about it though , as always radical change is hard to swallow and unless you build it and sell some to let people experience it properly so they can judge for themselves you will never know if it will catch on.
good luck to him
5:58 ...🍺🍺🍺🍺🍺👍
Looks like paraglider pilots would like the seating position
Not really...Pod harnessed pilots are in the reclined position like the your gliders
I can just imagine the replacement canopy cost !
They are all expensive, so insurance normally takes care of it if you break one!
Good to see some interesting thinking, gliders are all identical, and repetative. Its a backwater.
Imagine using a pee bag or pee tube with this setup. Someone could get a proper eyeful! :) I'm unsure on the seating position too. My initial thoughts are the more upright position wouldn't be as comfortable on longer flights. Whilst I know we don't pull high G's in general the more upright a person sits the quicker the onset of black out / red out would occur. Probably a mute point though that.
actually wouldn't peeing be easier in this position?! a lot of people have trouble peeing while reclined...
@@PureGlide true about the position to pee in yes. However I still think a more reclined position would be more comfortable for me on longer duration flights.
At the end of my one flight in a FA-18F Super Hornet, my buddy "Dorf" took the controls and came into the break at NAS Lemoore. At 500 knots. We went by the control tower, and they were looking down into our cockpit. He wrapped it up seemingly at 90 degrees AOB, and pulled the nose around to the downwind.
We pulled 7.5 Gs for 180 degrees. I was grunting and straining for all I was worth, but my whole world shrunk to about the diameter of a coffee-stirrer straw. Also, I remembered everything I did when I was three. Pretty sure my spine is in a farmer's field about a mile upwind from the runway. At any rate, the pilot's seat in a Hornet is not reclined, but Dorf had absolutely no problem keeping himself from GLOC, thank goodness!
To be fair, the F16 has a pilot's seat that is reclined nearly as much as a typical modern sailplane, and those pilots regularly sustain up to 9 Gs.
P.S.
We were still too fast to put the landing gear down at the 180 (start of base leg for civilian patterns), so he wrapped it up again just as I had come back to full consciousness. 6.5 Gs around the turn to final. The three green lights (gear down and locked) didn't come on until about 2 seconds before we touched down. I was physically wrecked when we pulled up to the hangar, and clumsily got out of the jet while Dorf gleefully asked if I had a good time. I remember dizzily replying "oh, that was great!" and then I went back to my BOQ room to fall asleep in my flight boots. That was at 1500 (3 p.m.). I didn't wake up until 0900 the next morning...
And Dorf had two more flights that he flew that day.
Soy fanático de aviones rc y este glider es fantástico para el entretenimiento. ¿Quieres ir rapido? Formula 1 . ¿Quieres sentir que vuelas ? Este es un buen ejemplo. Me gusta.. se necesita un prototipo y un video de vuelo desde le cabina.
This is the design submitted by my Town Council's Finance committee.
Might attract some of the motorized pilots.
Could do!
Early gliders and many modern ultralights fly in a similar configuration, only with no actual cockpit or bodywork whatsoever.
I don't really think the merit of this design is visibility.. It doesn't strike me as much benefit to do such a big redesign for that purpose.
But I can see some benefit, for people who are perhaps less flexible and have problems getting in and out of a regular glider (people with mobility problems, disabled or older folks)?
not sure how you kept a straight face
Hope it remains on the drawing board an interisting concept with many conceptual flaws. With very little gliding experience time might change his priorities. The cost of a flying prototype might be a sobering devolepment. It has got to look good to attract buyers.
Very strange placement of the instrument panel, I am very unsure how that would be comfortable or practical to use.
Helicopters and bush planes have this instrument panels.
Can I leave an email address and get a reply when this is in stock?
Haha i can offer a t-shirt
It''s a model
Designing gliders is like flying MAT tasks: 0 points for creativity.
apparently thinking he wants the pilots to die if they crash into much of anything lol yeah its got great visibility... but almost zero protection from frontal impact.. and looks easy to somersault on accident also...
Those instruments cant be read easily can they? Maybe its just the image but that setup doesnt look practical
It’s in portrait format, not landscape, for the TikTok users.
It's an electric sustainer concept? Does the propeller fold down from the back of the fuselage?
Yip sure does, just like a typical self launcher.
great visibility long lost since primary gliders
This designer has lost sight of the two most important concepts in aerodynamics, which are coolness and dignity.
At least long-distance racing pilots now have room for a portable toilet.
Who wants to go first????
What is this
The frontal area is massive and the high speed performance would really suffer.
So, I'm guessing he's looking for investors?
Thanks for this video - I would not buy this.... I think safety is a real problem for this design.
