I bought an after market gimbal tilt control lever for the back of the transmitter on ebay. It fits perfectly and turns the yellow square potentiometer quite well. Only problem is, the camera doesn't move. The instructions say to check functioning in Assistant software: Basic --> RC --> Sticks Monitor. It doesn't move these; in fact the sticks monitor moves when S1 moves. Is there something funky about the Phantom Vision that it doesn't have this feature enabled? Can someone tell me how to get this to work. BTW - I fiddled with the two yellow potentiometers. Is that a problem? What do they control?
