Dam SSGT I Know how much you love flying that one!
Its already repaired. All the damage that happened is what you saw. It is a tough plane.
I am adding doublers to the front and I will be painting the bottom a lighter solid color with a roundel on the left wing. So when my daughter spins it from 100 feet high, and I let her go too long without taking back control I will be at least able to get better orientation, or if I'm not, it will survive the crash better. At dusk a black plane with a solid black bottom is hard to keep orientation of.
White gorilla glue in your wings and bbq skewers reinforcing the undercamber wingtips is cheap easy insurance.
