JR XS3 aux channel not working correctly

[kb.bear]

the servo works the radio works the "A" button does nothing. I am using the aux channel in 2 position mode to control the forward and reverse on a LST. If I reverse the servo in the radio the servo swings the other way

Any ideas?

Mine did this on my LST not too long ago, Servo was fried. Not bad just some burn marks when I opened up the case. I guess not bad enough to cause the servo to stop completly, but enough to only allow it to work one way. Don't know if your in the same boat as me but it sure sounds the same...
