RE: Parkzone North American T-28 Trojan
To get a greater roll rate, you have to increase the throws, to do that you need to either increase the throw distance of the servo arm which is probable already at it greatest point, or increase the throw of the aileron control horn. You do this by moving it closer to the aileron. With the rod connected to a hole closer in you get move movement in the aileron for a given movement of the servo. Hope that makes sense. Heres a photo to help.
