I am going to have to put a trim tab on my aileron, just wonder who else has done this and how big of trim tab is needed..
I also need to know if any one that has done this has any drawing or dims of the trim tab and how much it needs to be bent.
Thanks
Mike

I would bend it more or less after my test flights, until I found the right amount. Then I riveted it in place. It's underneath the flap with the trailing edge of the trim tab aligned with the trailing edge of the flap, so you hardly see it when you walk past it.
