I am seeing the rudder skin oil canning problem on the RV-7A rudder I am building. I just started riveting the skins on when I saw it so I stopped and checked the forums. I saw some posts from years ago indicating that this is not uncommon. It's in four spots on each side of my rudder. Has anybody found a good way to deal with this in the last couple of years? I spoke to Vans Builder Support this morning and they said it's not an aerodynamic issue and is inevitable to some degree but it still makes me a bit uncomfortable. I still have access to the inside of the skins and could possibly do something about it if there is a good approach.
