This video was posted as an answer to another question:
The plane is quite hard to even see due to traveling at a high speed in a tight loop. Is it actually being actively controlled around that loop, or is it just a question of getting the control surfaces to the right attitude then watching the wind accelerate it it round and round the loop?
I can see the wings have been painted in contrasting black and white against a bright orange body, but are there any other techniques or "tricks" to giving the pilot feedback from the plane's position and attitude?
(I'm aware that FPV exists, but it doesn't seem to be used for planes very much compared to drones, is that correct?)
