I had a problem with several of my control surfaces fluttering when the antennae was down. I replaced the receiver and it seemed to take care of it. However, I still have some intermittant flutter in the ailerons when I first turn the plane on.
Any ideas?

There might not be anything wrong here. If you have the antenna collapsed and it is a few feet from the receiver you shouldn't get random servo movements but if you are too close to the receiver with the antenna down you can get some jittery servo movement. How far apart are the TX and RX when you test this? How far away can you walk with the antenna down and still get commanded servo movement?
One more thing; the batteries are fully charged, right?

That sure is a different definition of flutter,,,,

I am within a couple of feet when it occurs. I don't have a problem when walking away and checking the controls. The batteries were fully charged. Maybe just being too close is the problem.
Thanks.

Servos "chatter" in this situation.
Surfaces flutter under airloads.
It's just to clarify the situation.
