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.

Since most of the energy for the launch (until you break ground, anyhow)
would be coming from the wheels, would this qualify as a ground launch?

Inquiring minds want to know...

Sorry, Vaughn. It would be considered a self launch. But, just for special effect, it would be cool to put clorox on the tires, so you could do a burnout as you are taking off!

I wonder about the tire footprint on grass fields. We might be seeing the
tires digging little trenches.

I'm looking forward to the burnouts on asphalt! This is a silly idea. You're better off with a bungee cord to get to take-off speed.

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.
