Here's some before and after pics of my “handy work”.
I haven't tried flying it after I repaired it (I'm a little gun shy) so I can't say it's flyable but it does feel solid and, hopefully, is not too heavy now.
Fortunately, my wings were pretty much intact but I had read that polyurethane (Gorilla Glue) and toothpicks or, better yet, bamboo barbeque skewers can give quite a strong joint. I've used that combination on my fuselage. The only new purchased part is the motor.
The new landing gear is homemade...brazed welding rod.
Good Luck on your repairs.
