David,
Wonder if you can do me a small favour... Can you check the distance from the prop driver face back to some reference point on the mounting lugs? I want to design a mount for the front intake version for the Demon but I have the rear exhaust version to go by only. I don't know if that measurement is the same, although I'd guess it may be and the crank is either cut for front intake or not.

That would be cool... I'm trying to build a library of mounting plates in CAD for the Demon. For the K&B the crankcase is identical for FI and RI, so I just need those dims. For the .46, the beam template and the distance to prop driver would be needed. I'll check the OS website, there are a few resources there.

Got it - that was too easy.
After rpm it is A thru J, H, S
Higher pitched QM40 props look about right in terms of load. But APC has discontinued the 8 and above pitch, with the rpm climbing I suppose in the QM40 events. Eliminator has a wide range of candidates too.
