I've used medium strength thread locker with flat washers with some success on the canopy that has cracked, but I think I will try putting the small blasa squares and see what happens or make it permanent and figure out how to get it in the truck. I've use flat washer, lock washers, and thread locker on the cowl and that has worked great for that. One wheel pant keeps vibrating loose. Got to keep the truck its payed for and use the money on a new plane its cheaper.
