Just by wayu of further endorsment of my high tech aproach. My Gee Bee Y model profile was damaged by a freak encounter with the very strong blades of grass at a contest recently, It broke the Rabe rudder off, sheared thehinges. It shattered the prop and sent shrapnel through the monokote covering opening up several 2 inch slashes in the covering. I still had 3 flights go to for the contest. Luckily a combat guy was close by and I stole a roll of 2" packing tape from him. I used the tape to seal the covering holes in the wing, cover the exposed balsa in the nose, and made hinges for the Rabe Rudder all from the two inch tape. Uh I am still flying it with the same repairs,, cant justify recovering the whole wing at this point in the season so it is what it is,, so far no problems at all
