The VM Pro Spinner for folding propellers was developed for electric gliders to optimize the drag and also the optics on the model. The VM Pro Spinner has been optimized with the VM Pro Propeller, but other propellers can also be mounted on the 8mm blade mount. Even with other propellers, a much better result is achieved than with conventional spinners. Competition pilots in particular report noticeably lower air resistance at higher speeds. The VM Pro Spinner comes with a matching Allen wrench and three caps in white, black and neon yellow.
