Hello Paul,

Is there a formula even approximate that would
equate prop RPM, Diameter and pitch to HP?

I know HP increases with the square of prop RPM
but it must be possible to get a better relationship,
or am I dreaming?

Thanks,

JP

Vance on here has some prop software written in BASIC.
Last I heard he was in the hosipital.
But here are a few of his programs you can expierment with.
And some others I think.

Thanks Paul,
It is great and
I have something to play with for a while
JP
