Craig:
I have a three scimitar blade MT-12
constant speed prop on my LNC2. The entire propeller and extension only
weighs 45 lbs. Since I have an IO-390 engine which is a little heavier
than the IO-360's the W&B worked out perfectly. The blades on
MT's are repairable and the wood internal structure will be easy on the engine
in the event of a prop strike. At 25 squared I get a solid 200 KTAS.
From an efficiency standpoint a 2 blade will always do a few knots better
than a 3 blade but will not be as smooth running.
Cheers,

Hi Guys,
Does anyone have
any feedback on different props for the Lancair 320/360?
Has anyone
tried a Hartzel Scimitar? MT? Any performance differences
over
the standard Hartzel 2 blade?
Thank
you,
Craig Schulze
