E-Help tutorial how to fly electric hangglider

[@initialo2054]

The yellow text could use a black outline to keep it readable throughout the video.

[@billcallahan9303]

That's wonderful but where can I buy one? I've looked all over the net.

[@ericoschmitt]

Bill Callahan I even tried emailing the creator but got no response...

[@whisperingeagle]

@@ericoschmitt erico theres more info on other vids but i do believe you have to build it yourself . I think there is some instructional videos available

[@AcrodesignerLNSNI]

No, the E-Help is not an commercial available product. It is a free engineering homebuilder product. Anyone can copy the design and many homebuilders do.

[@freshnelly]

That's the way to do it, bravo!

[@4aleksei2]

Great video! Thank you, Reidar. is it planned to release 3 parts "How it is made" - Installation on harness? (on Myth?)

[@AcrodesignerLNSNI]

4aleksei2 That’s a good idea. Will do 👍

[@MegaWurzelpeter]

Nice video. Is there any place where I can buy this system and does it have an official admission/license for Germany?

[@AcrodesignerLNSNI]

Only available for home builders. In Norway it is legal as launch help/ sustainer as long as total weight of glider, harness and E-Help is less than 70 kg. And pilots hold a FLPHG checkout and SP4 licence. In Germany a type approval would be too much cost and effort for me to go down that road. The german E-Lift is approved but quite expencive and a lot of works gone into that.

[@ecoturismovalle1570]

Awesome. Is the motor + battery pack for sale yet? thanks

[@AcrodesignerLNSNI]

Hello, no the E-Help is not for sale. Battery pack is not type approved.

[@ecoturismovalle1570]

@@AcrodesignerLNSNI Hello Reidar and thank you for responding. If it gets approved some day or if you develop a different kind of battery pack, would you please let me know? Thanks.

[@brendan8978]

A very helpful guide, many thanks for posting Reidar :). Couple of questions, you refer to "big prop", have you moved up from 34"x14"? Also, do you top-up charge your lipos with your vehicle at launch, or only at home-base? And is that shiny new aluminium on the end of the motor-boom ;)

[@AcrodesignerLNSNI]

Big prop is 34x14. Actually the video is 24x12 which for mountain launch is more than enough push. The shiny thing on the keel support is a lexan wheel diameter about 100 millimeter. Need for some good rolling on the ramp especially if need for take a step backwards to position better for launch. Batteries I never charge on launch, only do at home with balancer charger.

[@AcrodesignerLNSNI]

I only charge at home

[@MrElectricglider]

It should be exactly like this! e-help

[@cloudsculptor1]

Is it powerful enough to foot launch from flat field ?

[@AcrodesignerLNSNI]

Not this one. Battery is 0,5kWh and prop is 34x12. For comfortable flatland launch we prefare 1 kWh and 34x14 prop

[@cloudsculptor1]

@@AcrodesignerLNSNI thank you for info . I used to fly a mosquito but electric looks sooooo much easier. Are there any forums covering self build ?

[@Jutte777]

Hey Reidar, What are your thoughts on the Airborne Fun ?

[@AcrodesignerLNSNI]

I love the Fun 190 for electrics. It is an old design though so comparing it to my modern floater the Icaro Piuma 186 it is not as good as the Piuma. Top speed, sail cleanliness, turning coordination, ease of takeoff, static balance and looks are better on the modern floater. Mind that I have flown the longest XC flights in the sportsclass in our country this year. Beating the U2’s, Geckos and Sports with this two floaters, the Fun and the Piuma. Love to fly them both.

[@superbeetlejosh]

Have you considered lithium-ion batteries?

[@AcrodesignerLNSNI]

To low C rating on Lithium Ione for our use

[@dogbone369]

Can you jettison the battery if it starts on fire?

[@AcrodesignerLNSNI]

No, it is absolute illegal to jettison anything from an airplane. For CAA experimental approval we had to prove that the battery can be dealed with in the air. Since 2013 to 2019 we have had no serious incidents with batteries. I had a short circuit in a wire harness in 2014 that blew up one of 4 the 52 volt packs. This happened in about 900 meter agl. Firewalls worked as planned and battery burned out in about 60 seconds trailing smoke. Just continoued flying.

[@NicholasSladenDew]

Very inspiring Video!

[@aeasus]

I understand windmilling will cause drag but will it recharge the batteries?

[@AcrodesignerLNSNI]

Yes, it will recharge the batteries in avkind of uncontrolled and not very efficient way. It happened once accidentically some years ago before we learned to activate brake. A topless pilot speed glided from high altitude and thermalled up again. Prop windmilled for long time and over charged the battery. Permanent magnet motir produce a BEM voltage when windmilled. This voltage drives a current back to the batteries via the freewheeling diodes over the mosfets. It can sound like a good thing but it is not. If overcharging the batteries they are damaged. And the drag from the windmilling can be very high, not justifying the free re charge

Hola . Me dirias q motor . Q variado y q baterias usas . Me interesa comprar uno

[@nimint3400]

Why motor on the human?

[@AcrodesignerLNSNI]

For positive pitch stability the thrust line must be at or below mass center

mark r Scranton pa thx so much u make me fly my very best
