Hi there,
i have seen that video and im asking myself how could this plane control its flightdirection so exactly.


View this video on YouTube

As u can see it tumbles a bit, then its taking direction.
Only small moving of the aileron takes the plane up to flight straight ahead,
1. it must be very fast as u can see on the vibrations
2. the airpressure on the flaps of the aileron must be like the same on the ground.

Why can i control with the given airpressure and speed my direction in 100.000 feet, but cant control the speed with propellers at this altitude. Same principle i think.
I have heard that u cant take your plane above 30.000 feet because the air is too thin and props dont work.

How high can i go with a hexacopter?
one year ago i wanted to start a project, but i was stopped by that information.

anybody an idea why i can use the "airthickness" for controlling my plane. its against science, or is there any mistake in my logic or information?
