Group,
            looking to fit a prop to my P ported renesis and need to
know what actual HP it will generate and not an enthusiastic guess.
Would I be safe in aiming for 230 HP?  Apparently if the prop is too big
nothing works, so smaller seems to be the aim.  Any suggestions ??  It
will be a fixed catto prop, and as usual craig Catto has been caught
many times before with HP in engines.  Actual HP not guesses required.

What gear ratio is your gear box?

If it is a 2.85 the prop will turn about 2600 and the engine
will turn about 7400 and make 250 HP plus or minus 10.

We need to get a group buy together and find somebody to make ground
adjustable blades for a Warp Drive type hub. That way you can fine tune
the pitch without buying a new prop.
