i have read the threads about this and i have a few questions before i fix it. my first build had a heavy wing and it was very easy to fix it with a wedge, so i am inclined to do that with my rv12 rather than bending the trailing edge. i have questions about using a wedge. is there a reason to put it on heavy or light wing? it would seem less noticeable to put it on the underside of the flaperon but i see a lot of wedges on top of an aileron. it would also seem better to put it at mid wing. then less likely to hit the hor. stab if it leaves and also not ''torquing'' the entire length of the flaperon. soooooooo... put it on light or heavy wing and is it best on top or bottom.
