Turnigy 9X not working?
I have a Mode 2 Turnigy 9X transmitter for my quad-copter (3DRobotics APM 2.6) and it worked almost perfectly at first for a $90 controller. After not using it for a while, I tried using my quad-copter and it wouldn't arm (start). I plugged it into my PC to check the transmitter settings in the APM program and the sticks do not work anymore. The left stick does not show movement values at all and the right stick (throttle) does not go to the lowest value (~900) anymore, only to the highest. The left stick is what is used to start the quad, which is why it wouldn't start in the first place. Why would the sticks suddenly stop working? Also, about a week earlier, a screw fell out of the inside of the transmitter (heard it rattling inside). Would this have anything to do with it?
