A new set of rubber bands to hold your wing on is the cheapest insurance you can buy. These rubber bands are made of the finest latex and are fuel resistant. Rubber bands are a common method of wing attachment because, in the event of a crash, the wing can separate from the fuselage, thus saving it from the main impact. Packed in convenient 1/4 lb boxes, approx 100 per box. #32 bands are 3" x 1/8"
