This is just a heads up for people still using the stock Tx/Rx gear and have put a lot of hours on the Tx. (ie. 1+ yrs old)
I noticed some erratic turning on my SC while flying recently. The rudder servo appeared to be jumping around and not responding well to the Tx stick commands. It almost seemed like a bad servo. However I traced it back to the joystick rudder (left/right) pot inside the transmitter. The potentiometers in these Tx's are not the best quality I assume and are fairly open to dust and dirt from the top of them. I shot a few sprays of contact cleaner into them and worked it in using the stick. It seems to have solved the problem.
