Flap Seal

Mounted my flaps last night while doing final things that need doing before I mount my wings to the fuse, I found that the curved part of the leading edge of my flaps do not contact the upper wing skin at the trailing edge.

My friends RV6 always rubs in this area and makes a good seal.

Do I need to bend the leading edge of the flap to pull it up till it contacts the wing skin or bend the wing skin down to meet the flap or do nothing?

I have one side that is nearly perfect, and the other side has a decent gap. I plan to tweak the "ski jump" on the wing side to close it up, but I left mine to fix another day. I wouldn't mess with the leading edge of the flap...the wing side is where you want to make the adjustment.

remember you will likely put the uhmw 3" wide tape on there. and that stuff is .032 IIRC thick. you can flex the curved protion up a timy bit also. but i say let it lay for now.

I am pretty sure that my wing skin is in trail and follows the airfoil. I will check again tonight with a ruler.

When I pull the flap all the way up till it stops, the top skin of the flap where it curls is contacting the flap brace closer to the center of the radius than what is shown on the plans. This makes me think that the flap skin was over curled at the factory leading to the gap.
