I am working on a project to limit the inputs on a joystick on a RC quadcopter transmitter.
Simple enough to add a 10k linear dual gang rotary potentiometer inline with the wires coming off of the joystick pot.
It works fairly well, except for one small issue that I've not figured a way to solve yet.
When my limiter pot is at about 50% travel the joystick pot gets thrown off center by a very small amount but only in one direction. . I can see it in the application that calibrates the joystick and when the quadcopter is flying it'll start a very slow turn. The limiter is on the yaw.
Does anyone have any thoughts about how I might be able to elimitate what I think might be a bit of feedback in my circuit?
