<x-html><html><div>Rick,</div>
<div><x-tab> </x-tab>I
didn't want to say it before, but since Jeff raised the issue... There
has been some discussion that the counter balance beam is not stiff
enough and is actually vibrating in bending or shear. IF this is actually
happening then YOU ARE IN FULL AERODYNAMIC FLUTTER and may be living with
a very dangerous situation. I don't know how to approach the solution
other than to say that I hope that: 1) you're flying with a parachute, or
2) you have an auxiliary roll control device hooked up, or 3) you can fly
without that aileron. I tend to doubt the bending theory because I think
the vibration would then have been endemic to the class, but it's well
worth investigating.</div>
