Hi David,
I agree 100% with you about the effect of high twist blades on ground cooling
and
the possible improvement of the cruise performances, but I am puzzled by your
figures.
Your figures for the Woodcomp low twist prop suggest these blades are very far
---From being suitable for this engine (914) as they need to be set at an
incredibly
high angle to transmit the power. It is very likely that the blades are fully
stalled during the early take off phase, therefore reducing the take off
performance.
It is even possible that they are partially stalled (at the tip) at
cruise.
My point is: if you start from a very bad prop, almost any other prop you try
will show a significant performance improvement. It would be very interested to
find out how the performances of your Woodcomp high twist prop compare with
those of the Airmaster/Warp Drive.
Remi
