Facing the right side of the heli looking at the retainer that holds the tail rotor...the rotor as stock rotates anti-clockwise....pushes air in your face. So tail in, the stock tail rotor forces air to the right...pushing LEFT. No matter which way you mount...the tail rotor has to push the tail to the left when more thrust is applied to the tail rotor.
yeah, you took the words right out of my mouth =)
One other thing is that if you make it so it is spinning so the bottom of the tail rotor comes at you from behind the heli, you can get a roll over situation and bury your heli =( Make sure that the top side comes at you, and the bottom side of the rotor goes away from you. That will make the rotor forces cancel out and get you away from that rollover condition =)
Also with these DD blades there is a leading edge and a trailing edge, and it's good to get those right, even though they do not have to be in order to fly. Maybe someone else can post pics before I get to it, but if not I'll post some pics soon =)
