Please, for those of us who L-O-V-E specifications, and would lime to k ow what the harness, battery, motor setup would cost, what its power is, discharge time, etc, - would you please list those things, sobthat a curious bloke could go look ant them like a child with their nose pressed against a candy store window? Thanks. And thank you for posting the video. Looks like that was fun flying. The only critique I would offer, though, is that you put your feet intonthw boot of the harness pretty early after takeoff. Had a fuse blown, or other sudden power of situation occurred, would you have time to get your feet out to land standing up? Peace and good landings to you!
The Last European 15-20 minutes depend on your flying style. However, it is a tool for hunting thermals from flats or hill, not an ultralight. For endurance flights on pure motor then gas is better.
@@AcrodesignerLNSNI better for range, but not for safety, unfortunately. I care a lot about safety and such things as low maintenance need as well as no need to start and kill the engine, so that you get instant throttle or instant full stop, make electric motors just better. I wish they had the same range though.
Super SWEET setup. Super garbage propeller though - my mates paramotor is so quiet you cannot hear it at all above the sound of the waves lapping the beach. Was the prop damaged or something? You can literally hear it ripping the wind apart and wasting energy like crazy.
Well well. The tip speeds are pretty high and it doesent help that turbulence from the pilot hits the propeller. The choice of that small prop is to keep it practical and small but still at an sensibel efficiency. If u look at my channel I have many versions with bigger diameter props and low sound. However, they are a bit big and cumbersome. Keep it small.
Well, E-Help is not an commercial available product. Homebuilders can make cooies as much as they want. Free engineering and tutorial videos on my channel. Cost for all parts is about 2000 - 2500 eur I think.
Well, problem with LiIon is hopeless low C rating. LiPoly is much better on C. For doing a flatland launch u need a reliable 135-140 ampere supply at 52 volts that does not reduce under load. Doing the math there regarding C rating only LithiumPolymer do that reasonable well. If using LithiumIone problem is that to extract 135 ampere from a battery that only can do 3C will take a big and heavy battery, huge Ah required if LiIo. The LiPo u see on this video is rated 65C an gives explosive thrust and power for a takeoff on a 8 kg and 1 kWh battery.
@@mohammadhallajian1 Glider is the Icaro Laminar, it is 18 m2 and can carry about 120 kg total. Take off weight on this rig is glider 23kg, pilot 85kg, harness and parachute 8kg and E-help 16kg.
@@AcrodesignerLNSNI Thanks! So: A 34 kg thrust E-motor + 18 m2 glider's wing can lift off, total of 132kg load, right? Based on your experience is it possible to lift off the total weight of 250 kg? what is the required thrust and wing(m2) ?
Reidar Berntsen mmm, my doubt is the curved wingtips , the mellow stall/ fly in pre-stall should be different for example for dune gooning. I really love this new floaters vs my comp t2s. They are a breeze in everything. I can even say easier then paragliding in almost all aspects. And with power, a great safe combo. Cheers
The curved tips with the raked tip thing makes it the sweetest pussycat ever. Great softness and forgivness. We push this glider in hard turns maybe closer to ground than is healthy for us bcs it feels very confident.
Looking forward to see that video 😊👍 Make sure to test a good positive climbrate from mountain before flatland. And do the flatland thing with a good headwind. Zero wind is risky and hard usually.
@@AcrodesignerLNSNI it would still reduce power drain and extend your flight time (flexible panels are extremely light) and can give you a bit of power for a go around if you have been flying for a while unpowered
@@AcrodesignerLNSNI 18 meters is great actually, half the power can be provided by solar panels. It's decent. Plus you are recharging while on the ground.
In motoring this prop has an efficiency of about 65% and in generatoring about 15% due to the camber is wrong way then. It then means that energy coming back to battery is very small compared to the drag from windmilling that impairs the gliders performance vastly. A windmilling prop is like flying with a dragchute. We use electric brake to avoid windmilling.
i dont mean to be so off topic but does any of you know a tool to log back into an instagram account..? I somehow lost the account password. I appreciate any tips you can give me.
i think the world is ready for some engineer with a better understanding of aerodynamics to design a personal flying device that uses the same principle that a manual hydrofoil uses, but for air instead of water. I can see it in my mind. i just need to become an engineer.
Well. The hangglider has been developed over a periode of 50 years since beginning of 70'ies and is a quite mature and nice aircraft for its niche use. Aircrafts are always a compromise of a lot of demands and needs. So heading an electrical aircraft design with priority ONLY in performance will for sure sacrifice a lot of other nice features. Like ease of logistics, ease of safe launch and landing characteristics etc. I have flown E-Help a lot with very high performance fixed carbon wings, see my channel previous E-Help versions, and performance was a lot better than what u see on this fun beach video with the Piuma. However, ground handling and logistics with the fixed wing was very much heavier. So it could in practical not be flown from other place than airport.
@@AcrodesignerLNSNI Really looks like it hasnt evolved much since its original design. Just different variations of the first design that worked. Im imagining taking off from a stationary position and creating propulsion with your vertical shifting body weight and aerodynamics, exactly like a non-electric hydrofoil surfboard, or a large heavy bird.
Amazing man !!! That " Seagull" landing technique made my day !!!! Ha Ha Ha !!!!
Worked long time on that technique :-)

What's the motor and prop? Manufacturer and model?
This is very neat, surely a must try!!! How much does one of these things set you back?
15 grand
How much does the entire kit cost? I'm truly intrigued!..
Probably a lot more than it should
Hi Boris, that looks like so much fun. Can you or anyone else tell me where to get the gear. Regards Phil
I am not Boris. The E-Help is not an commercial product, it is only experimental
Nice flight! How do they compare to paramotors ? And how long can you stay up with one charge ?

Hi again, i just noticed this is using LiPo battery. I assume Lithium ion can be used too or would the controller need to be changed?

I think lithiumione has too low C value for flatland takeoff. The lipo’s used on the video is 65C
great job Reidar. what is the minimum power of motor to lift the glider off the ground?
7 kW and about 34 kg thrust

hi Reidar,this video is still using the rewinded motor with lower KV?
Lei Yu Yes it is the 105KV rewound motor. I don’t think it would have been possible to do this with the original 150KV
Hey Reidar, looks like you don't have a grip of the upright in the takeoff run while hanging on to the remote throttle?
Myabe one hand at some point
Lovely. How do you feel the flat takeoff Piuma vs the Fun? I've notice the windy day.
Both ar quite easy starters. The Piuma is a bit easier to control pitch in the run

where can I buy this?
Landing like a man on the moon 🏆
I think I'd want that propellor a little further away from my feet. =O Pretty cool, though!
Actually done that on the 2021 version, check video of foldable propeller
Where could a person buy this setup?
It is not for sale due to HES reasons. Never been certified for commercial sale. Only for limited use in Norway
Stunning power...¡¡¡ YEAH...
I love it!!! Clearly you do too.
Please tell me the name of engine and where I can buy it?
It is the Turnigy Rotormax 150 from Hobbyking. However, stator winding is rewound from 150KV to 105KV.
where can i get one ?
Flexible fuselage
Very flexible :-)
hello, which GoPro are you using?
Gopro 5 Session
Flexible solar panels on the wings to extend the flight time
1 m2 solar cell produce 0,1-0,2 kW and this thing need about 4-5 kW to zero sink. The glider is 18 m2.

This is the REAL DEAL.!
It actually works and is in regular se as thermal hunter. However, works best from small hill.
Dude how much coast ur mosquito? 🤔🥺
What’s the tech spec on the motor and battery
Motor is the Rotormax 150 rewound to 105KV. Battery is 52 volts about 1 kWh, 65C, weight 8 kg
WHAT will they think of next? Maybe a flying suit in case your parachute gets tangled?
Awesome!
Living the dream
Probably likes the vibrations.......
Any vibrations are aerodynamics. Propeller work in air not laminar, airflow disturbed by pilot harness.
That's abit cleaver!!.😎
AWESOME
what motor use?
Rotormax 150 rewound to 105KV
Looks like fun! ;)
How fast ?
Como eu faço para adquirir um desse
Very good
Bravo slovenac 💨

My wife don't think so :-)

He he. I know what u mean. I do 90% of my flying old school and is a dog for XC. However, this motor thing is a fun sidekick. And gives airtime.
