RE: Venture 60 wing
I think you are okay, also. When you mount the wing in the fuse you will adjust for the funny sweep in the wing. You'll set the wingtip-to-nose and wingtip-to-tail distances the same for both sides. It will be like you have a little bit of a trapezoidal wing planform instead of a pristine rectangle.
You probably will never notice. If you had an identical one built correctly with the same hardware and CG, then you'd probably notice some minor differences like staying trimmed over a wider range of trottle settings etc.
