ABSTRACT:
A device for winding a rubber band motor has a very light weight so that it may be carried by a model airplane, almost without any weight penalty. A pulley with a recoil spring has a string wound thereon so that the release of a pulled string rewinds it onto the pulley. A clutch mechanism engages the pulley and rubber band when the string is pulled and disengages when the string rewinds. This way, the string may be pulled repeatedly in order to store more energy in the rubber band.
