I have to agree. Large throws effect it more. Since you are on the sticks hard with 3D, I would say not to worry about it. If it becomes a issue, get a hitec digital, adjust the servo speed to compensate and you should be in business. I still say to adjust your ATV and subtrims and you should be able to minimize the effect.

Geistware-I always setup max ATV going for best resolution, zero subtrim (never had before), best mechnical advantage. It is noticeable now that I am trying to learn 3D at large surface throws. I never before had owned a top of the line transmitter or tried 3D, so I never noticed it. It does not seem to affect any of the best pilots, but it is there so it has to have some influence.
Just my 2 cents. RALPH
