Parts Wanted L/F OS Max EX- M Crankshaft

[Wasted wages]

Just came into a stash of older OS Max .21 engines,, 1 of them only needs a crank to be complete..

Not sure about the different OS models,
but the two types of motors are EX and RX.

Any OS guru's out there that can shed some light about these motors?

If anyone has an old Crank stashed away they would part with, please let me know..

Frank, the crank you are looking for is an inboard??? Could you post a picture of the crankcase??

Yes it is for an inboard....I saw that one on eBay, but it will come from Columbia...

If I can get confirmation that the EX and the RX use the same crank, I might take a chance and buy all three...

This is the RX...

Both motors appear to be the same thing as far as the crankcases....

I guess I can break down one of the RX motors
and see if the crank will fit in the EX.... duh..
