Hi all,

First let me say a huge THANK YOU to everyone for your help. You have all been extremely helpful.[sm=thumbup.gif]

I did several things to the plane this week. I moved the battery pack and receiver further back which enabled me to install two shorter extensions on the rudder and elevator servos. I moved shortened the throttle pushrod as there was a 1/2" overhang near the throttle servo lead so I wanted to make sure that was not aggravating the situation. I did some more research and found that we have cell phone tower nearby the field which may or may not account for the fact that this interference is happening at the field and not at home.

I went to the field this morning and tried the plane and although the flutter was not so bad, there was still flutter there. So I finally did the twist thing, not so much as a last resort, as that I wanted to isolate whether this actually fixed the problem.

Guess what???!!! It did. After twisting aileron, rudder and elevator servo extensions in a reasonably tight twist, none of them ore even buzzing. So I guess the twist thing did it.

A friend of mine (one of the instructors at the field the guy who solo'd me) is an electrical engineer and he explained why this works. It makes sense. He also explained that the cell phone tower may actually affect the signal on the lines between the receiver and the servo and that this could explain the problem.

Anyway, my plane can now fly!!!![sm=biggrin.gif][sm=biggrin.gif][sm=biggrin.gif]. Tomorrow I'll be getting the chief instructor to take it up (it's a policy we have at the field) and hopefully the plane will fly like a dream.

Thank you all for your help. You guys have been terrific.

regards,
Bruce
