Indoor rubber powered model airplanes typically use a rubber motor made of a single loop of stripped rubber whose ends have been tied together with a pair of knots. In this video I show the process of tying two reverse overhand knots in the ends of a segment of Tan Super Sport (TSS) rubber and cinching them down to minimize waste and get close to a target weight, e.g., 2-grams. This process is valuable in indoor duration flying events such as F1D, F1L, Limited Penny Plane, A-6, as well as the Science Olympiad Wright Stuff and Flight events. It is not necessary to apply CA to the knots.
