It really does seem like a serious CQ problem that it is ALWAYS the red wire on the aileron gimbal. That's not random.

I guess it won't hurt to try to repair it. It will certainly test my soldering skills. If it works, it works. If not, then I was going to have to get a new radio anyway. I do like the simplicity of the RDS8000 (otherwise I wouldn't have bought 3 of them over the years) and since my WWI models doesn't need fancy 10+ channels, it does almost everything I need it to. It doesn't however offer throttle curves and with the Seidel/UMS that would be a big plug.
