About this Product
Water propeller for use with waterproofed brushless quadcopter motors (right handed spin direction with typical backward facing propeller cone pushes forward). I have tested this with a small ~900kv Turnigy brushless outrunner that I waterproofed by epoxy coating the internal windings. It works great! given the high RPM, it does produce significant back torque, so its not the most efficient, but it makes for a good model submarine thruster because no moving seals are needed.
