Unbelievable fun machine!
You can see the landing is going thru turbulence!
Decided to go public on 26 Jan 2021

Amazing little aeroplane.
Very impressive performance of that plane
It's so cool to glide, land, wings level & then taxi. Nicely done !
It's awesome electric glider nice landing lovely
thanks!
Towplane? I don't need no stinking towplane 👍
Silly...I AM the tow plane...
This thing and Swifts use to own this space; but a lot of cool F103/DHV120Kg soaring electro-wings appearing on market. Atos Wing, Birdy, GP10, this space getting real interesting real fast.
don't forget 1comet! www.1comet.com/
@@ronaldgliderholy moly, it's pretty!
@@MrPilotStunts It is an incredible flying machine.
cooli Maschine, das würd i au mol gern fliege
Nice. Where was this flight from?
Mollis airport, (LSZM), in Canton Glarus, Switzerland
Would be interesting to see if you could get some regen of the prop say slowing your speed for landing and dropping alavation
The prop folds away (backwards) when the engine is not running to reduce drag - hence regen is not possible
Wow l like it very much
That rattling sound worries me a bit. Is the prop well balanced?
it's also loud. I fly with earprotectors.. The sound is caused by limited clearance between tail-boom and ground (don't forget during take of with nose up, this becomes even smaller). Hence a small fast-turning prop is needed. It is a compromise. Yes, the prop is balanced, and we clean it before each take-off to ensure best possible aerodynamics.
Very nice especially if you have to land in a field out in the boondocks until the storm passes. I wonder if you can use an APO to charge up the batteries while soaring around.
APO=??? If you mean Photovoltaics: we've looked into this - they are heavy, and would need to flex onto the wing without changing the aerodynamics. Up to now, we have no solution
@@ronaldgadget Flexible solar panels exist. Ebay: £100/130W. Weight approx 5lbs. This doesn't include the charge controller.
@@onepalproductions yes, we just need better ones than those
@@ronaldgadgetthere are fitting solutions. Such as the ones used on the sunseeker duo, solar challenger, solar impulse etc. Many companies were onto this. I suppose, the problem is the target audience. You need a lot of enthusiasm and a lot of money to want to buy such aircraft, and archaeopteryx is expensive as it is.
@@MrPilotStunts I have flown the Sunseeker Dou with Raymond... I know the plane. The reason this plane works is because it flies very slowly, which only needs a 'simple' airfoil, and therefor allows to put solar panels on. It cannot sustain flight on the panels alone: it does need the battery. The idea is to charge battery before flight, take off, stop engine, fly using thermals and charge the battery, which you can then use again for a few minutes.
Yes, the Archaeopteryx is expensive, but worth it!
The best of both worlds. The best of every world.
When I first saw the add for it, I thought it was impossible and just a joke. I attended the demo day and signed an order at the end of that day. Then I had to wait... A very long time - but absolutely worth it! This plane is a marvelous compromise between gliders such as DG's, and AS's and paragliders. Great glide ratio, easy to fly (no medical needed in CH!) and very quick to assemble: 15 minutes and you are ready to fly. The Swift for instance needs more than one hour, and careful attachments of flight controls is needed. For the Archaeopteryx, all controls attach automatically and no mistakes can be made. It was built by a perfectionist, for instance there is mechanical mixing of flaps and ailerons..
Did you have a wingman holding, out of sight for take-off and the landing or how did it stay upright on what looks like a mono undercart? Lovely plane.
There is a wingman at take-off, but not at landing. Tomorrow I'll publish a video of a field landing, where thru a combination of wind and inertia we can keep the wing level until we come to a complete stop
@@ronaldglider Thank you for the answer. Been working all day on our Spitfire, hopefully soon to being finished.
@@dave20thmay Sounds exiting!
it is *more* than exciting...!
That waning beep is a bit unnerving 😳
audio vario, not a warning
There is a warning beep when the motor is 'armed' so the pilot know it can start the propeller and make sure no one is hurt... So it is unnerving for a reason
1:59 Look Ma ,...No Hands.....LOL........God.........I wish I had one like yours...........
The hand or the plane?
@@ronaldgadget LOL...the Plane...of course..
lovely, soaring the sky above, among majestic mountain..... What a wonderful world... and so here in Indonesia.... I wish at least I have a paragliding parachute... I lived surrounded by mountain as well
I see the stick on the right, what's the stick on the left for ??
That is for the flaps - along the trailing edge of the entire wing. The flaps are also used for airbraking when deployed more than 30 degrees (all the way to 70)
So its similar to the spoiler activation on gliders ?
@@Techy111 Well, only when more positive than 30 degrees - otherwise it's more like glider flaps...
Have they thought of putting solar panels on it?
yes - so far we have not found panels that are a) thin foil so they can flex over wing b) affordable and c) with sufficient yield. We would not be able to maintain altitude with panels, but can charge battery (1 hour charge for 6 min run time)
They thought of putting a water tank and a steamer, a box for the logs and maybe pedals to move the propeller.
@@aquigley8114 Yes, just after the Flintstones era
Far fricking out ... are these things available?
Yes, you can order them from www.ruppert-composite.ch/en/
@@ronaldglider
Thanks for the link.
That is a impressive piece of kit
how much cost ?
www.ruppert-composite.ch/en/ shows 89'500 Eur
Elektro model -> EU89K+
This is another proof that Elon dream about electric - flight is not fantasy.
Here is another one: www.lange-aviation.com/en/produkte/antares-20e/
Ruppert Composites sells this machine, see www.ruppert-composite.ch/home-2#tm-top-a for pricing
What is the glide ratio for the electric version?
unchanged: As the propeller folds backwards, the glide ratio remains at 1:28
das Landerad eiert...😆
genau!!!
How much power?
it's a 10kW engine, see en.wikipedia.org/wiki/Ruppert_Archaeopteryx
@@ronaldgliderdo you happen to know how much power it needs to maintain level flight? I'm guessing 5-6kW.
@@MrPilotStunts The propeller is really small, and only has efficiency at max power. I do not know how much amps it uses to stay level, but it is more than 50%. To make distance, do a dolphin technique: Max power for a while, turn off engine, glide at best rate and repeat.
@@ronaldglider interesting! Thank you for the insight. Makes sense that the prop is optimised for max power, it's meant for gaining altitude after all, not crusing.
