Editorial Review Our FMS 4250 series propeller adapters are CNC machined from billet aluminum. They are designed to be used with the FMS 1400mm and 1450mm models which use the FMS 4250 - 500KV, 540KV, and 580KV series motors. These propeller adapters have been designed with an extended propeller shaft to allow for a large variety of propellers and hubs. The propeller shaft is 52mm long from top of base to end of shaft. They have the proper hex nut machined right into the shaft for a perfect fit. We have also added a 10-32 tapped hole on the end of the shaft to work with a variety of aftermarket spinners. Will also work as a stock replacement with the original hub.
