120 kg Electric Glider BIRDY - AFFORDABLE Future of Gliding? | AERO 2022

dude, why did you make a video of a partially assembled glider?

I want one

how much does the motor + batteries weight? a twostroke + few liters of gas is smaller, lighter and has better mpg

Absolutely very interested.. would be nice to see you test flying it.

open cockpit : how much extra drag?

does the prop as brake.. also regen the battery?

I don't believe its only 120kg unless that's it's empty weight without the battery pack.

Seems dangerous to have a shaft that long .. if it break .. what happend to the structure ?

What are the specs! The surface area ! The aspect ratio,!
Stall speed!

103 legal requirements are to have it with less than 24 kn stall speed and that will dictate what will be the surface area size and total wing load..

Cool project but I don't like tail. It adds a lot of difficulties for take off and landing! Solution without spoilers is interesting but what if you don't have any power in the batteries? Glide performance is impressive!

Nice work Stefan, love the content

where can i find a link to these folding props for sale? do more than one company make them? thanks stefan.

wow

It's amazing work

Wow👏👏👏👏👏

Nice

Nice one

thank you stefan i enjoy it

good view

Nice

Nice

You call it affordable, but you don't say how much.

keep safe❤❤

Great

Nice...

Would be great to see more about this glider...

Nice

Nice

👍👍

Yes! Enjoying your channel Stefan and would love to hear more about the Birdy EMG

How much weight would a parachute add for the glider?Seems like it should be mandatory. Would give great peace of mind.

Schönes Video über ein gutes Flugzeugkonzept. Was ist die Gleitzahl vom Birdy?

So, how much in USD? lol

It's missing solar.

Progress everywhere. I like their approach. The parachute to save both human and machine should be mandatory on all gliders according to me (I get that overall weight problem is a thing but priority to safety).

Yeah let me fly it to work

How much?$$$

Thanks Stefan. This was what I waited for. Minimalistic and simple. Only issue now is how much does it cost.

Yes please wow, also if they would produce a side by side 2 seater would be something super special

Why build a mere flight extender when you can build a self launcher?

Ultra light.. no CS22 burden.

I'd like to see an FMEA for using the electric drive as the speed brake, it requires the complex system to function vs the simple mechanical spoiler. The spoiler function, if not available, can be compensated for by flying uncoordinated at the cost of higher pilot workload, so it may be acceptable.

Why is he talking about meters and kilometers per hour, climb rates of meters per second?
These aren't aviation units of measurement.

Altitude is in feet, climb rates are feet per minute, distance is in nautical miles while speed is measured in knots.

The numbers he's quoting mean nothing to an aviator without a calculator.
Covering up bad performance with changed numbers?

Dankeschön, Stefan! Deutsch engineering at work again! Cheers to you from the States.

Nice looking glider. Electric motors for airplane is a mute point: it looks simple but it is not. You need a heavy inefficient battery (very polluting) an DC/AC converter, an expensive permanent magnet (from China) motor and the dreadful limited range.
For the same weight and less money you can get a gasoline (petrol) engine that can go 10 times longer.

I love the utility of the pusher prop in the tail, doubling and replacing the spoilers!

Finally an ev that not only is sensible but it really does fly well done

Isn't an electric glider an oxymoron?
