This seems pretty freaking awesome or maybe it will lead to a bunch of fatalities. Either way, I want one!

I am very curious to see if that thing flies or not. "waiting for their lakes to thaw..." hmmm.

I want one of these: http://www.jetlev-flyer.com/

I like this one....

FlyNano ultralight looks pretty cool . all except eating all that Prop. blast .

It hasn't been test flown yet. Supposedly that will happen some time in May. One big problem I see is a complete lack of wing tip sponsons. That's going to be a bit of an issue especially in a cross wind.

I'm no aeronautical engineer, but I have built a few aircraft, and I think they forgot a few things. takeoff on water, hell, MOVING on water takes a fair bit of power. Even the 35hp dragging 190kg of water is going to be tough. The "box wing" design is very stable and strong, but very inefficient as far as aerodynamics go. ESPECIALLY slow speed aerodynamics.

Essentially ALL other "ultralight" aircraft barely make the US weight limit of 254lbs, A lot merely claim 254lb but allow for spec weights to slightly increase from model to model. The fact this company claims it is getting FAR better performance out of half the weight of existing models is suspicious.

Finally, flying at even the low speed they specified in something with such short span and small aspect ratio is going to take a bit of skill. Not a ton, but I doubt anyone without enough flight training just have a pilot certificate would be able to even take off. Much less survive a flight.

I very well may eat my words here, but that is OK. It just means how impressed I will be if this ends up working the way they are advertising it to.

Does it even fly or is it just a ground effect vehical?

"Service ceiling 4 km" Im not an aeronautical engineer, but it seems to me the vehical flies

not sure about Euro standards, but that sounds like an altitude selected to avoid the need for an O2 system.

So it basically can still be ground effect only, but it won't take off from a lake situated higher than 4km I guess.

It also lists a spec climb rate in m/sec. (3-5m/sec)


It is advertised as an aircraft. I doubt they would make a fuss about the legal aspects if it was ground effect only.


The more I think about it, the more it seems like it could work. Still not sold though. 35hp could give you easily 120kg of thrust with a good prop and tune at sea level, but 70km/hr is pretty slow. we will see.
