| Actually, there is more movement for 120 degree than 90 degree. With 3 servo 90, only one servo moves for elevator, while in 120, all three servos move. If the pitch or aileron servo is a little faster or slower than the other, you stand the chance of going forward and to the right or left slightly when you give forward elevator. With the 3 servo 90, you only have the elevator servo in the back, or front working to move the heli forward or back, and the swash pivots on the two side servos. Four servo 90 is harder to setup and acquire a setup with no binding through out the pitch range with a cyclic movement. Some people tell me that they like the four servo 90 so if they loose a servo, they can still land. That really is a false sense of security, since if one of the servos locks in a particular spot, you are going in.Quite frankly for scale and medium flying, you will never know the difference. Even Curtis has said that the 140 degree eliminates alot of the interaction, but not all of it. Only a handfull of pilots can feel it anyway.
