I've flown the V911 and the V912 almost exclusively. I own a Wasp X3V (It's collective pitch). Today I flew the Wasp for the second time, instead of just hovering it. First flight I crashed it into a wall. Minor damage. Flew figure eights and circuits. The 911 and 912 prepared me for that.I haven't used a simulator up to this point for the helicopters. Mind you, I have Fixed wing experience, and can fly some 3D with same. A Lot of sim time with planes.
Get a Heli sim and the V911, and you're golden.
