'Dan:
I don't know what my prop pitch currently is. It was repitched from a 200hp ranger prop, or at least it had 200hp stamped on the face of the flange. They took three degrees out of it and said that they couldn't go any more. It ended up working real well. I'll look at the paper work and see if the pitch numbers are documented. I only have about 35 hours on an overhaul and the climb seems to be improving as things seat in a little better. As far as the brakes go, it seems to stop really well. I have never noticed it pulling to one side or the other but we have a lot of concrete and I don't get on them real hard unless I need to. I think the 37s and 38s were a little light in the tail anyway so I don't tempt fate unless necessary. The few times that I have stood on them pretty hard everything went straight down the runway.

Mark, John,
Thanks for your comments.
John, I don't think I'll be needing your prop.
Mark, my 24G was seeing about 90 mph cruise at 1825 rpm using the 63"
pitch wood prop. Climbs great at sea level, but it's a dog at altitude.
Do you know what your Curtis Reed was pitched at?
I'm starting to think harder about aeromatic props. Consensus seems to
be that it is the optimal performance solution. Is Ken Traver actually
shipping anything? Does anyone out there run an aeromatic on their 145
Warner powered Fairchild?
Also, I appreciate your comments regarding the mechanical brakes. I do
enjoy the simplicity of them, but gotta get that grabbing out. I gather
you are able to stop in a straight line?
