rubber stretched same length shorter 1oop applies force glider shorter time force/time impulse Ive few chances try Category catapult interesting results new glider weighs about 35 g too heavy Category can flown 40 feet using 1oop 029 rubber 208 rly rubber too strong Category Using short 1oop stretched less high impulse overpowered gliders structure Nothing broke trajectory hump like car crossing speed bump longer 1oop length higher launch angle gave far launch consistency Next time Ill start much longer loop shorten until launch angle highest glider can use peak altitude just below ceiling
