I need some help:

I had a problem with servo bouncing (3004) on one of my planes. This servo was one of the elevator servos ( UCD3D). After replacing it, I noticed the problem on one of the ailerons (Ailerons are on different channels 2 and 6 ). I checked everything I can and still can not find the cause.

Here is the shocker. Yesterday I was getting my other plane ready for the first flight of the season ( GP Space Walker ), the left aileron was bouncing around the center when released. What is going on here???

The only common thing between the two planes is the TX and my basement where I keep them.

Any suggestions on what to check next. Please note that when I ended the season last year everything was working more than well.

Amer.
