    When fitting a fan to the engine do i need a woodruf key?
    Its just i bought the engine but it doesnt have one, just the space for one.
    It may be a mistake as ive lost many of them on the shed floor with my plank OS engines

        No they screw on or are fitted with collets .... Check the manual for the heli see if you need the washer or not and where it is supposed to be fitted ... if its not fitted on some helis it will foul the starter shaft..
