ing the rpm to about 5200 rpm with prop pitch. (Anything below about 5200 I b
egin seeing a slower speed.) I see about 3.7-3.8 gph in this setting for abo
ut a true airspeed of 115 mph.( A friend that has flown with me thinks I get
closer to 120 mph at this setting.) If I want to burn 4 gph I can get about
120 mph. Not bad on 80 hp.

I wonder if this would be a good idea without a manifold pressure gauge.
It sort of sounds like the no nos about lugging an automobile engine.

I either read or heard somewhere that with the IFA prop you can fire
wall the engine and trim the prop to 5500 RPM for your max cruise speed,
any experience with that theory of operation?

I get about 5400 rpm static run-up with my 70" IVO prop in full
take-off/climb pitch. It can easily redline during takeoff, since I do
not have any stop washers on the prop. I would not let anyone else fly
the aircraft, since it could be easy to over-rev during takeoff. Not
sure if I would recommend this situation to anyone else, but I have lots
of hours on the a/c and am very used to its abilities. I usually climb
out at 60-65 mph ias and 10 deg. flaps with great success. In cruise I
set the throttle at about 5500 rpm and bring the rpm to about 5200 rpm

I installed the same prop with a 812ul behind it on my model 5, I only
have about 60 hours on it and am very pleased with the performance, was
wondering if you would be willing to share how you trim your prop for
takeoff, cruise, etc, also did you set the stop nuts on the screw travel

wouldn't fly behind anything else, even though it takes a bit of
maintenance once and awhile. I cruise around 52-5300 rpm at 115 mph,
burn under 4 gph and can get 120 mph if I goose it up to about 4 gph. My
climb out, even here in the Mile High City, is real positive. I wouldn't
be able to get this performance without this prop. Also, I fly a lot of
cross country and really like this prop for this purpose.

Sacha,
Most of my numbers are very preliminary. And after flying the actual
test phases, it was mostly to put the required 40 hours on it and I
throttled back because distance was not as important as time and I
didn't want to burn more gas than was necessary. So numbers are not
finalized.
I was getting about 100 mph at 5000 RPM. During the test phase in
probably 85-90 degree days, climb was very close to 1000 fpm. The 1300
I mentioned was at a temp in the high 50s to low 60s. As I do the
longer cross country flights fuel burn will be more apparent. I chose
the 68" prop because that is what was recommended by the guys I knew
that have been running the Warp prop.
One issue I did have with the Warp Prop is that one blade would change
pitch one degree after running for a short while. I would re-pitch it
and it would change the one degree again. I contacted Warp and this is
there explanation. The aluminum collar is placed in the mold and the
resin and fabric are the inserted and cured under pressure.
Occasionally the resin will shrink away from the aluminum collar. He
explained that is the reason for the holes drilled through the collar at
180=C2=B0. The resin is supposed to run into the holes and act as a
pinning mechanism. Apparently this was not working on my prop and he
suggested I pin with aluminum pins.
I drilled two 3/16" holes through the collar and into the hub about
3/8" deep. and about an inch from the hub end. I cut two pins of 3/16"
aluminum and glued them in the holes with a structural adhesive. I
have to say here that this is what I did as I forgot to ask him for the
factory recommended procedure. If anyone else is having this problem, I
would suggest calling for the exact recommendations.

I am actually looking for a prop for a Kitfox IV - 80hp. Thinking Warp

Yeah one of the issues I still have about installing an IFA is
that there is no more space on my panel to install the extra instrument
for reading the MAP as far as I understand (which may not be
very much!) it=99s not really wise to be without one.

Stan, All,
I either read or heard somewhere that with the IFA prop you can fire
wall the engine and trim the prop to 5500 RPM for your max cruise speed,
any experience with that theory of operation?

LLoyd-
I get about 5400 rpm static run-up with my 70" IVO prop in full
take-off/climb pitch. It can easily redline during takeoff, since I do
not have any stop washers on the prop. I would not let anyone else fly
the aircraft, since it could be easy to over-rev during takeoff. Not
sure if I would recommend this situation to anyone else, but I have lots
of hours on the a/c and am very used to its abilities. I usually climb
out at 60-65 mph ias and 10 deg. flaps with great success. In cruise I
set the throttle at about 5500 rpm and bring the rpm to about 5200 rpm
with prop pitch. (Anything below about 5200 I begin seeing a slower
speed.) I see about 3.7-3.8 gph in this setting for about a true
airspeed of 115 mph.( A friend that has flown with me thinks I get
closer to 120 mph at this setting.) If I want to burn 4 gph I can get
about 120 mph. Not bad on 80 hp.

Stan,
I installed the same prop with a 812ul behind it on my model 5, I only
have about 60 hours on it and am very pleased with the performance, was
wondering if you would be willing to share how you trim your prop for
takeoff, cruise, etc, also did you set the stop nuts on the screw travel
to limit the high and low ends of your pitch adjustment?
