Just a thought. If you look into the Hitec's be sure and search both here and over on the F-Giants site for HS-79XX jittering and jumping issues. Hitec is now beginning to recognize they have problems (The FG site has about 145 pages of comment). I have some HS-7955TG and 7985MG Hitec's that are jittering pretty bad so I've been following the issue. Hitec is now saying it can be resolved with a firmware update but I'm not sure if that requires sending them in. I suspect it does mean as much. Just wanted to make everyone aware of that little issue.
