Hi Paul,

I did some static tests on my Warp Drive prop.  I wasn't sure which
prop I had but after talking to the factory I found that it is he HP
3 blade version so it's good to fly.  So far I have two data points,
20 deg - 5250 static
18 deg - 5500 static

Readings were at 6200 ft and about 30F.

I'm going to test fly the 18 deg setting as soon as I can get to the
airport on a good day.  Yesterday was perfect conditions, cold and
calm.  Unfortunately the plane wasn't ready.

I take it that was a 2.17:1 PSRU.
I assume this jpg attachment is still the intake manifold.

It's a 2.85:1 PSRU.  I found Bill Eslick's data at
http://www.weslick.com/Prop%20Charts.htm  He's was seeing 4900 rpm
with an 18 deg setting and I think it's the same prop although he must
have left hand blades.  The RPM's look like they were a little lower at
80 mph, so the prop must be stalling a bit at static.  I assume he has a
2.17:1. Also it looks like his airport is at 710 ft. That is the intake
manifold but it has a cone filter on it now.  I'm not running the
engine without a filter in New Mexico. :)
