Dear RV Friends,
As the new owners (not the original builders) of a beautiful RV4 my partner and I are sorting out a few issues. Specifically...
The left aileron suffered some hanger door damage with the previous owner and that damage resulted in a very heavy wing we can not trim out with the installed manual trim.
We intend to build a new aileron once the Northeast USA "nice flying weather" season ends in late December so this is a temporary fix.
I have read the Van's document "How To Diagnose And Fix A Heavy Wing".
But at this point we want to fly, not experiment with a permanent fix to the damaged aileron which will be eventually replaced.
A ground adjustable (bendable) aileron trim tab seems to be the quickest and easiest temporary fix.
So My Questions:
1) What thickness of aluminum to use for the trim tab;
2) The best location on the aileron for the tab;
3) What initial dimensions (length/width) to use as a starting point.
(We would initially secure the trim tab with Mach 1 tape for flight testing, then reduce the size of the tab to the minimum required through flight testing before permanent installation with cherry max rivets.
Your answers to the three specific questions above are greatly appreciated.
