REFLECTOR: O-540 Propeller

[Brett Ferrell]

Steve,


We started with a Catto prop on our XL (with IO540), and we flew briefly
with a Prince, and the airplane flew very nicely with both.


We have since upgraded to an MT.  You do need to be aware that it's a
totally different airplane with a fixed pitch prop.  It may not trouble you
much since you should have a fair amount more power than you did
previously, but it will not accelerate they way it did with the MT, and it
will not want to slow down and will not descend as steeply with a fixed
pitch, so just be prepared for that.

  I have replaced the Franklin in my Elite (longwing) RG, with an O-540.
  Expect about 250HP.

  On the Franklin, I had an MT prop - great performance, but the blades
  were fragile.
  Anyway the MT had a different bolt pattern for the Franklin so won't fit
  the 540.

  So now I'm looking for a new prop:
  Given the additional weight of the 540 over the Franklin, prop weight is
  important;
  The 540 gives an extra ~30HP over the Franklin so maybe a fixed pitch
prop?
  I'd like something a bit more robust (and less expensive) than the MT.
  2 blade Vs 3 blade?

  Anyone flying with an O-540 ?

  Catto? Prince? etc.....

  Recommendations / suggestions / experience all welcome please.

  Steve
