RE: modifying props ???
I have -for a looooong time used th next size up prop -then modified the blades to similiar of the size wanted.
Why?
rigidity
many cheap props -made in US had mismatched wood grain or depitched tips which frankly revved but did not pull well and or they flexed in operation.
But -there are now some very good import props (why in the hell do we always need import props to do the job right?)
Sh-t!
The new Bambulas, etc, made from beechwood are terrific props -tough , rigid -great performance .
Friend Ed Skorpa (ESComposites)has a line of props (imported) which are very similar to Mejzlic shapes These have the excellent clear straight grain characteristic I like.
