Title: PA 65 RE with Muffler
Post by: Fernando on August 26, 2007, 08:11:52 PM

 
 I mounted my Pa 65 RE with Muffler in a Strega ARF, made some flights this weekend. The engine is running very well, but I did not find a good a prop.  I tried a Bolly 3 blade 13x4,5 and one 13x4,5 2 blade that I bought from the Randy and was not good none of the two, I has to close to much the needle and the engine  got to poor. I also tested one 13x5 but wooden Rev Up, was the one that was a little better. Which prop I must use?
  Which size and pitch?

HI Fernando

I am glad to see you here, The plane you are using will need more pitch, I would suggest asking if your flying buddies know how to pitch up carbon props, if they do try  a 4 .75 to 5 pitch, The Strega has a very very thick wing which has a lot of drag, so you will need a prop to match that airframe

Regards
Randy

Fernando,

You might try to Google the Prather pitch gauge and see what pops up.

I bought my latest one from Darryl Cady, but I have since seen them in a few shops around the country.

If you are really brave, you could go ask my ex-wife if you could have my old one. It's sitting in the basement of our old house in Beltsville, Maryland along with some other choice CLPA goodies. Best of luck if you try this option - please notify us so we can alert your next of kin.   mw~ mw~
