I just bought this thing from a friend and don't know weather I am gonna keep it. He needed to get rid of it and I bought it. Quite frankly I am intimidated by this thing. I have never flown a heli and probably wont. I have taken it out of the box to check it out and thats it. One of my questions is what is the "norm/3d " switch do? does it make it easier to fly in normal rather than 3d? He is gonna give me his sim tomorrow and I am gonna give that a whirl but If I can't pick up on that I will sell this machine. Thanks for the help!
