Hi
I would also remember that although the OS 91fx is more powerful on paper 2.4 hp to 2.8 hp. The OS max figures are at an unworkable 15K rpm where as the MVVS develops it max power at a much more useful 11K

Bingo. The OS is rated at 2.8 HP at 15K (who uses props that small?). The MVVS .91 is rated at 2.41 HP at 11k.
Which HP/RPM range is more useful?
It's torque that turns the prop, not horsepower. The MVVS clearly makes it's (comparable) power at a more reasonable RPM than the OS.
I have a MVVS .91 that is going into a SA Excelleron. Looking forward to it's power.
