is it possible to fly 3d WITHOUT collective pitch?
if it is, how do I get it upside down?
also, how does collective pitch work, and what does it let you do?
when flying upside down, are the blades spinning backwards, or forwards as you would if hovering the right way up. I don't see how a helicopter can be upside down with the blades spinning clockwise (forwards). how come it doesn't give thrust UPWARDS and send the helicopter downwards?
