For Greyhawk:

Although my ailerons move freely on the ground, the  in-flight force required in my 4P is greater than I would hope for.  I was considering gap seals as a possible remedy.  Since I understand that you have installed gap seals on your machine, could we have your before and after experience with respect to aileron force and/or any other secrets you might like to share.

BTW, does any other L-IV have this problem?

Thanks, Bill Hogarty
