RE: I busted my Avistar
You'll need to carefully check the wing's structure. If the leading edge was damaged, it's possible that there's some damage in the spar joiner area. You'll likely have to strip the covering and look carefully. You don't want to find out at a later date that the center joint was damaged and then have the wing fold in flight.
A 4-inch strip of glass cloth on the bottom of the joint from leading edge to trailing edge would be good insurance after such damage to the wing.
