The competition optimized hand-made folding prop spinners come from the manufacturer Freudenthaler Modellbau in Austria. The caps are laminated from carbon in the molds and the propeller driver is made by CNC technology from aluminium. Both parts are completed manually by using carbon rovings. The spinner and driver without offset are offered white painted. The spinners with offset have a carbon surface. Both kinds can be custom ordered in white, black and carbon design. For the custom orders, we need about 3-4 weeks delivery time.
