With tails though a good strong joint will help with hangar rash. The stab on my Kaos popped loosed a few months ago because the Chinese ARF builders just hot glued it onto the edge of balsa at the tail with little support to keep it there. It was plenty strong enough for flight loads, but not strong enough to handle the bumps getting to and from the airfield. When I rebuilt it, I added some thin vertical grained balsa inside to keep the sides from splitting again, and made tri stock fillets on the outside to spread out twisting loads. The vertical wood was glued in with CA, and everything else was epoxy. All that added maybe a 1/4 ounce to the tail, not enough to make a noticeable CG change. But the tail is considerably stronger now, not for crashing, but to keep me from getting to the airfield and not being able to fly my favorite plane because the tail popped loose again.
