My spaceplane Idea!

I want to make a small scale space-plane that can fly normally with propellers, and when I command it, to ignite the engine inside of it.

There will be a tonne of avionics inside of the plane, with lots of sensors, and maneuverability.

I want it to be able to fly at, a minimal of 200meters high, and be able to stay above the ground for at least 1 Hour! To do this, the propellers will be powered by solar panels.

What do you all think?
