so im new to making rc boats and need to know how a prop shaft would connect up to the motor. ive been looking around and i dont understand how the two would connect up

[EDIT] after some thought i have considered making the prop shaft out of a wooden dowel. i could just drill a hole in one end to fit the motor and then use some kind of waterproof glue to glue a propeller to the other end. can anyone think of problems this may have? i have thought about the vibration upon the propeller and shaft connection but i think a poxy glue would hold.<br type="_moz" />
