Does anyone know how those people on YouTube and such do 3D inches off the ground? Is it a matter of experience or are they doing something I am not doing? I'm able to flip and roll and fly inverted, but I have to be way up in the sky to do it.. Do I need to give the heli a quick positive pitch pump to first bring the heli up, then roll backwards, then give the heli a quick negative pitch pump to bring it right side up?
