Servos not centering

[Mad Baron]

I hope someone might give me some ideas on this problem I am having. The aileron servos on my BUSA Bristol hunt for center after returning the stick to neutral. I am running a R2006GS Futaba receiver and a 1300 LiPo 7.4. I would post a video of it in operation but I don't know how to upload videos.

Just curious - what happens if you center the servo with a servo tester. Does it still hunt? If it does, you know it is the servo itself.

I put my servo tester on the ailerons and they worked fine.

If you apply aileron trim while they are in the "hunting" position, do they continue to move?
