Prop choices for OS 91FX

[Rcmaster199 at aol.com]

OK I wasn't sure about  the pipe you used. Thot it was 60 size. A pump  also 
right? Were you ever able to get it to run reliably without a pump?

Matt to swing the 17x10n cut to 16 with authority a person will need a  15cc 
pipe @ 25", plus or minus. Nothing beats the ES pipe. I don't  remember the 
number but it is 1 9/16 od x 26in  OAL.                         Nat

Piped correctly, this engine has enough grunt to turn much larger  props. 
I've seen it turn a 17x10 cut back to 16" on a 81/2 pound model. Nat  Penton had 
it on his VooDoo Xpress with a stretched pipe (60 sized), and it  ran around 
7600 rpm. Very nice performance; would hover at half  throttle.
