I need some help with a Freefly 360 modified servo for the tilt axis that I use with an external pot. I'm using the Rusty's gimbal with the 5k external pot (PEC pot) on the tilt axis. From the servo, I got 2x3 wires coming out. One of the wire is connected to the APM (RC8 : digital signal + positive + ground) and the other 3 wires are connected to the external pot. But I cannot get it to work. The tilt axis is just shaking like crazy and does not respond to the stabilization signal from the APM. Below is a video that shows the shaking :
Any help would be greatly appreciated ! Thanks in advance.
