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 you dont need it, just put the fan on, then locktite the nut on to it no woodruff key needed

Thats it woodruff
Cheers mate, thought i'd lost another one then

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..

You dont need the washer for the shaft to the fan in the Titan
