REFLECTOR: RE: HIGH SPEED FLUTTER

[Alex Balic]

Tom-
Did you add weight to the aileron that you added the tab to  in order to
balance it after the tab was installed?

I recently added a ground adjustable trim tab to the right aileron.  I is 10
inches long and 2 inches wide.
 
After that the aileron started fluttering at around 150 KIAS.
 
I timed it down by on-half inch ... then got flutter at 180 KIAS.
 
I am going to trim it more ... does anyone have a trim tab on their aileron?
Have they experienced this phenomenon?
 
Should I have added a little weight to the other aileron to "balance them
out"? 
 
Prior to this I have tested my plane up to 195 KIAS and did not get any
vibration or flutter.  So I suspect it IS the trim tab.
 
Any thoughts?
 
Tom
