Thanks to all for the responses.
And re: rain, the plane is hangered.
The thing that gets me is that I dont recall it ever being a problem
until recently (over the last year maybe).
I am going to do a few test flights and apply Gary's check and move the
flaps small increments to see if that has an effect.

So I gather from your response, the Project X plane will be using this prop?
What were you seeing (numbers please!) on cruise and fuel burn as compared to your
AA-5 rocket?

Ned picked up his plane today. We flew for about 30 minutes side-by-side.
The CS MT PRop makes a big difference on cruise and fuel burn. I want
one.

Sounds great. I'm reading through 7 months worth of teamgrumman digests an
d eagerly awaiting my first flight in more than 8 months=2C the longest str
etch I've gone since 1998.

Subject: N119ST Jaguar
From: teamgrumman(at)aol.com
I've been working on installing the Jaguar cowling on 119ST for a week now.
Other than the owner=2C no one else knows that 119ST was the plane I used
for all of my original company testing. 119ST has had 6 different prototy
pe cowlings=2C 3 different kinds of exit ramps=2C and 2 different versions
of air intakes tested on it. I used 119ST for a year way-back-when to test
a bunch of ideas. Check out pict 030.jpg.
I also had the cowling that is now on N1976T on 119ST about 3 years ago.
Maybe it's my familiarity with the plane or maybe that after installing 3 c
owlings in as many months=2C but=2C this one is going really smooth. The t
rim lines on this cowling are very close to the planes mounting flange. Th
is plane has one shim (I got two responses from you guys on shims and dista
nces to the spinner=2C thanks) on each of the top mounts and the distance t
o the spinner is just a shade under 40 inches. It's got to be differences
in bushings and mounts . . . . but=2C I digress.
The cowling should be all trimmed up by tomorrow. The missing baffles shou
ld be here this week also. Then=2C all the rest of the details.

I guess that IS the question isn't it.
Straight and level at 4000 feet, we were truing out at 152 knots. He was
running 2700 rpm, I was running 2830.
I could climb with him, but just barely.
Project X plane is next. I have a torque tube I'm stripping and getting
ready for paint. It'll be Red.
I've also ordered a windshield for Project X plane. The one that is in it
is too bastardized to make fit right.
As soon as 119ST is finished, I'll get started on it.

Constant speed it is
Pitch is from 11 - 35 deg
Scimitar shaped design
Weight with spinner 54.7 pounds
Difference between MT and other 2 fixed pitch is that it provides more thrust on less fuel.
Numbers will come after the turbulance and wind dies down and a good flight test can be conducted.
A thorough flight test comparison was done on the earlier MT STC that had the -17 blades and is available here:

All for now.....
Well I did fly 1240 miles to return home yesterday from the prop shop in California. I flew at 11,500msl burning 7.9gph. First part of trip here:

Yes, the MT prop is a constant speed prop.
