You are the second person that has suggested this to me. When the other person suggested it, someone who was with me told me that it was an old wife's tale and that there was no validity to it -- someone whose opinion I respect.
I believe in this wife's tale! My Funtana was doing the same thing you are describing. My fix was to use heavy duty servo Extensions. I also twisted the extension. I had picked up some JR servo extensions at a swap meet cheep! I got the good ones at RadicalRC!
