I lost y .60 stick when I hit a garbage dumbster on approach. Lost the engine and all of the airplane.
They sure are a fun plane.
From .25 up I am using 2 arrow shafts that tie to the center spar and leading edge and then into holes int he bulkhead in front of the wing. I make sure that I reinforce the part of the bulkead were the shafts go into and extend the reinforcement all the way to the bottom or the top if a low wing. On some installations I epoxy a close fitting Hard wood dowl inside of the arrow shaft. Overkill? Sure is, but it sure works. And the nylon bolt blocks are always FLUSH with the wing.
I have had the same expearance as AA5BYabove.
Added more rubber bands.
Now none of my planes use rubber bands. Look ugly.
Good luck on getting the bird back in the air.
Show us the pictures when she is back togeather again.
