Take some hight test wax string, or fishing line and attach one side to a wing dowel, and the other side to the wing. coil up about 10 feet of it and tuck it inside the fuselage or neatly under the wing rubber bands...next time your wing gets ripped off...the fuse and wing will stay together and tumbe down harmlessly. May even save the prop and you won't have to clean the carb!!!
