I think we'll put both a three-blade and a two-blade prop on for good

measure, on concentric counter-rotating shafts (a la Fairy Gannett or

Soviet Bear).  That ought to be good for some attention at OSH!   ; )

Down boy!  : )



Hey, doesn't Van's sell the MT prop, now, too?  Why don't we talk Van's

into doing a comparison between the props on one of the factory planes?

Makes sense to me . . .

Hi Paul,

  

 MT Propeller will design a two blade, or four blade, or whatever you feel  you want that is reasonable.

 They can even provide an aluminum 2 blade or 3 blade propeller.

  

 They designed a 3 blade "natural composite" propeller for the RV-10,  because their engineering analysis showed this provided the  best performance and overall characteristics.  Especially being 18  pounds lighter than the 2 blade Hartzell.

  

 A 2 blade "natural composite" MT propeller would weigh about 1 pound  lighted than the 3 blade propeller.  The 2 blade hub is much bigger to  handle bigger blades required, and the 2nd order harmonic vibration present  with a 2 blade propeller.

  

 Regards,

 Jim Ayers
