Those close-set main wheels aren't going to keep it level on rough ground.

Electric powered wheels to help get to flying speed is a very good idea though. Acceleration is not jets strong point.

3D modeling makes for such pretty paper airplanes!

I didn't see an intake for that jet...

It's there, it just isn't big enough.

"Turning the engine on (and off) is a simple automated procedure. A small airscoop is all that opens (and closes), the engine itself remains inside the fuselage, so in flight the turbine can be turned on and off easily with glide performance little affeced."

It is kinda cute.

"...kinda cute" - It is!

Bob K. says the intake is too small and, from the looks of it, I'd
agree. Maybe they'll incorporate spring loaded plenum doors which suck
in at low airspeed to provided the necessary air for the engine. As
airspeed and plenum pressure increase the doors close and ram pressure
provides all the needed air. I am a bit concerned, however, at having a
jet engine with as much as 1,000 deg C tail pipe temperature imbedded in
a FRP structure. Or is it a turbofan with a lot of bypass air to keep
things moderately cool?

CGI makes for a pretty airplane, but I'm not convinced of its viability.

"ProAirsport is currently building two demonstration aircraft (one each for the UK and US markets) with inaugural flights expected in September/October of 2015."

They're also talking about a soaring engine-off UAV version. Investors must like idea.

Other planes/developers have previously demonstratred XC soaring with autopilots in model size gliders.

They say that the wings are proven components off-the-shelf (COTS). Might that be the PW_5 wing? Best L/D is similar.

Curious what wings it's using. From the "airframe section" on their webpage, sorta sounds like they're using wings that are already "JAR certified", thus on an existing aircraft......

Oh, goodie!

I can buy one and sit at home while it flies and streams video to my
smart TV. Shucks, it'll probably post better cross country flights than
I've been doing...
