Hi Paul-

I'm still looking for a prop to use when first testing/tuning the
engine.  My thought was to get a prop -- any prop -- that would at least
prevent the engine from over-speeding, but not necessarily be one I
could fly.

Well, I've just tripped across a prop that might do both, and at a very
modest price (compared to the $2500 I was looking at with performance
props).

Anyway -- my question is whether this is a flight candidate.  I know
there are a couple of folks on here with magic prop software, perhaps
they could run the numbers & tell me if this would work for me.

Attached is a photo of the prop data plate.  Airplane is Mustang II. VNe
is 235mph.  Desired cruise is anything north of 200MPH. 13B at 230HP.
Tracy's rd-1c redrive.  Typical prop on a M2 is 68" 2-blade.  I *really*
want good climb performance, since my field is at 6873' and summer DA is
typically 9000' - 10000'.  6000' long runway.

I don't think that 60 inch prop is going to give you good take off performance.
Should or could be stalled for a long time on the runway. I think you need
a much longer prop. Perhaps 3 blade. Around 70 inches. Maybe 72 inches.
With less pitch.

That prop might be OK for Dave's turbo engine.
