Guys,
I noticed that on my .60 Extra 300S that uses dual aileron servos, I noticed a few issues :
-one of the aileron seemed to work a little slow and lag behind.
-Then it started to hunt the center  - ie when i neutrilized the input, it moved up and down before settling down.
- Also it did not seem to have proper holding power - ie I was able to move the aileron with little force.

I replaced the servo with another Futaba 3004 and took the plane to the field today.  However, much to my surprise, I noticed the same problems again ! with the new servo !
This seems to have stumped me. I know the problem could be with the RX or with the extension lead, but has anyone faced a similar issue before ?

Thanks !
