Bubba, I have put two washers under the bottom and it cured mine from going to the belly on uplines. The problem is i have put about 4 on the left side, the engine looks insanely crooked to the right, but it still heels left pretty good in an upline. I flew it this afternoon and noticed also in a harrier it wants to drop the left wing first every time. Is it possible that it is a lateral balance problem? When checking it do i use the centerline of the fuse or the centerline of the engine?
