As far as I know, OS105 use a R6ZZ bearing. So, the output crankshaft diameter is 3/8" or 9.525 mm.

Do you need a smaller diameter? Why?

Adam, its Alan from the Taunton Airport so many moons ago! The OS 105 is too new to ever have had a Heim crank. The biggest motor I know of to have one is the webra 75 P5. There was also a Webra 91 P5. Not sure if it ever had a hiem crank or not. These engines are quite rare now. What are you building?

YS .91 four stroke has a 8 X 1.0mm main shaft.The older I get, the fewer things seem worth waiting in line for.

Hi Alan. It’s has been many moons ago! Thank you for the info. I actually have both webras you mention. Just found them the other day. Was going to build a pod and boom but may just get one of my scales going instead.
