...at 162 mph!

EADS Cri Cri
2 x 15 HP electric engines
375 lbs of aircraft
Endurance: 30 min of autonomous flight, 15 min for aerobatic flight. Heck 15 min is all that's needed for base defense stall fighting :D!

I want one...

OMG Sylar is flying it!

It looks like one of those little clown cars.

You may be awesome pile-its, but your name is ridiculous. Therefore, I will use any excuse to show that clip. :neener:

Edit: Neat plane by the way.

I a few years the entire top skin will be solar cells, or battery cells and in daylight will fly for hours. :airplane:

I don't think so - 30Hp = about 22Kw of electrical power - solar cells for 22Kw would cover a large portion of the roof of a building. The surface area of that little plane just won't cut it. It's been a little while since I needed to buy panels, but the commercial panels were running about 15w / square foot (although the super expensive panels would do about twice that).

That's why it's gonna take a few years ;)

There certainly are limitations. However this electric aircraft powered by solar cells was aloft for 26 hours :).

i think the weight to lift ratio would be a big prob, solar panels are heavy. but anyways what happens when you run outta BATTERIES!!

Yes I know. Our Ham radio repeater up at 8400ft here in Idaho have very large solar cells, which cover with snow then the wind turbine kicks in and all this only powers a 100 watt repeater with a couple smaller link radios and an aprs digipeater, But intent was as fast as things are improving & new discoveries theirs no telling what we'll have in a few years. Our solar cells today are far more efficient then the ones in the 70's, thinner, lighter, etc. Would be cool if it could recharge or just maintain current for a longer flight.

Thanks...I should read all before commenting. :salute

I knew I had seen this. But the motors are very low wattage and it definitely a low powered glider, but very cool anyway.

Actually the now make solar panels that roll up like a poster and are very thin and intended for portable us. Some Ham radio operators like to do what we call QRP (Low Power) work. They'll take a compact radio, a small gel cell battery, throw a wire up in the tree and talk around the world. These thin lightweight solar panels fit in a back pack very well.

The Solar Impulse has 4 x 10 HP electric motors for a total of 40 HP, 10 more than the Cri Cri I posted. As a comparison for how many solar cells you might need, the Solar Impulse has a wing area for 2,200 ft^2 with 11,628 photovoltaic cells. Of course the Solar Impulse is designed to stay aloft 36 hours too (9 hours of it in the dark!) :) so you probably would need considerably less for something like the Cri Cri.

The Cri Cri has been around for a while.
They've used chain saw engines (oops I mean Rotax's :D ) for a while.
I saw this coming for a while now as it has been the buzz in the EAA magazines that I receive.
Unless they perfect this in a larger HP before I am ready for an engine, I'll just stick with a Lycoming, Subaru, or Mazda rotary for now :)

What are you building?

Very nice--keep us posted!

As soon as I can stop making crap for the Wrangler :)
The Cri Cri was actually on my list of why I was considering but the wife didn't want something she couldn't fit into (ie had to be at least 2-place)
Also it seemed like one has to be shoe-horned out of those things :)

Before I decided on the Bearhawk, it was a toss-up between the Rand KR2 or the Sonex. I went with the Bearhawk because of the cargo capacity and I wanted a decent and comfy cross-country a/c.

It must be odd for a pilot, going from gas to electric, in gas as you fly your plane, it gets lighter and performs better, i imagine not ever loosing any weight over time,but loss of power* "like all battery's do" would be a major setback to any truly long flights.
Still cool tho.

Hybrid would be cool. Kinda like the ME 163's had that little spinner in the front that spins the generator for the electrical system :aok
