They are easy to fly.
Its my electric powered Plyon racers that really move!!! And they are smaller. See here.

Most of the flight, (turns, rolls, etc) is in your head. You KNOW how to turn it, you know how it sounds, so you just "do it". One wreong move though and its very very broken! This is why I love thithium batteries! Lead batteries cannot actually be mode to fly without a huge fight. These have no such trouble.
This a a miniature pylon race class. We cant fit more power, use thinner wings, etc as its all regulated and you cannot break the rules... So faster is quite possible.
Could you fly this? The turbines, and pulse jets are easy, because they are bigger. So stay in sight longer.
