REFLECTOR: Take-off rpm

[davedent at comcast.net]

Mine was a 67X78. It should have been 67X80.  I'm sure it would have done better.  Paul Calhoun had the 67X80 and it did better. Catto told me later that mine did need the 80.  Paul's did something like 2300 static but on take off it didn't do as well as mine. I got a good 1000 plus but on the upper end mine didn't do as well. Paul's was seeing a good 190kts.  Mine only saw a little over 180kts. Some where I have this all written down. But by memory this is all that comes up.  I'm back to the MT right now and I was suppose to have gotten my new Vesta blades this week but it didn't happen.

  Dave, I have a 66" X 82" Catto three blade on a 260HP IO540.    @ 900 msl std day, get 2340 static, rising to 2450 ato.   G. Putney

          Anyone one out there running an IO-540 with a fixed pitch Catto three bladed prop, what rpm are you getting on take-off?  Just normal conditions not high altitude or extreme temps.
