				Hello Gaggle:
  
 I am looking for some information on CATTCO PROPS.
  
 This is their web site:
  
 http://www.cattoprops.com/index.html 
  
 Is anyone using their props?
   
 Info needed is:
 Three Blade Prop Vs Two Blade Prop.
 Is a 54" Pitch CATTCO equivalent to a 62" Pitch Sensinich?
 Why is there so much of a difference in pitch call-out between the two?
 I say this because a 54" is what was recommended / suggested Vs a 62".
  I did some basic calculations and for the same engine and going from a two blade to a three blade the pitch should be closer to a 60".
 I do not want a climb prop - I want a cruse prop.
  
 Does anyone have a spread sheet program or a web site for doing calculations?
   
  
 ANY IDEAS?
  
 Thanks Gaggle-
