> Wow, I must not have enough pitch or something is bad wrong. 5000 only gets me
90mph IAS and GPS. I do not have wheel pants or lift strut fairing or the radiator
speed fairing on yet but I cannot imagine it will make 30MPH, assuming
you are calling 120mph VNE
VNE on the model IV 1200 is 125. Even in dead calm weather, I'm not comfortable
flying any closer than 115. If it's even a little little bumpy, I bring that
down to 110. That's usually around 26 in Hg of manifold pressure for me. As you
pointed out, you're probably pitched a little flatter then I am in this configuration.
Without being able to adjust your pitch in flight, you have to make
compromises between climb and cruise. With an 'in flight' adjustable prop, I
can have my cake and eat it too :-).

I'm getting ready to finish and install the instrument panel fiberglass dash board
supplied by Skystar for my modified model IV. Anybody out there have any suggestions
for finshing the dash, eg leather, vinyl, carpet, painted etc. I'm
leaning towards some kind of thin carpet, but not sure where to get some or how
to install.
Thanks in advance for any suggestions

Mine has some kind of thin carpet like material that was glued in place. Over time,
the glue has failed in spots causing wrinkles and bubbles. It gives the whole

I was asked over the weekend why my fox goes so fast, my reply was, as I was grabbing
the wing struts (plastic) must be because they are not glued, as I twisted
them up. I said that when in flight they adjust to the center on their own.

WOT = Wide Open Throttle. Meaning your throttle is pushed all the way in. Actual
RPM will depend on air speed, prop pitch, density altitude, etc. Relevant to
this discussion is the fact that an in flight adjustable prop lets you control
your RPM without changing the throttle.

WOT isn't an rpm. It means the throttle is all the way in and the manifold
pressure is close to 14 in Hg. Rpm will depend on how much bite you have
your prop set for.

Noel, shouldn't that actually be up around 28 or 29 inches MP (depending on
variables) when at full throttle? Perhaps we're talking about different
measurements?

Only a suggestion but I would never use hardware store hardware on any
aircraft. You do not know what you are getting. I have seen to many
airplanes crashed because parts were not as strong as they should have been.
It may be legal on a homebuilt but there is a reason it is not on a cert
airplane.

The strut fairings are the biggest and best mod you can make. I tried 4
different fairings until I found the best. That is the stuff that kitfox now
sales ( I think) from no fairings to the new is about 9 mph. The wood
fairing that was used behind the strut is about 3.5 mph. I was scared the
first time I flew with them, the plane used to hit a wall like yours and it
flew past that and changed her sound, weird, but very cool. You now have to
think about how to slow the thing down. My speedster is 720 lbs. And I
licensed it for 1320.

| Subject: | Re: What are the differences between a Model IV 1050 and |
Model 1200 Kitfox ? Increasing groos wt from 1050 to 1200.
Lowell,
This very subject was one of my first discussions with Frank Miller when I
began repairing N316R. Your take on the subject is correct except for the
missing rod diameter. I was told by Frank that replacing the older 7/8"
lift struts with the new 1" lifts and adding a 1/4" 4130 carry through rod
inserted into the carry through tube would provide the increased strength
for 1200 lb gross. The 4130 rod I acquired from AircraftSpruce and then I
threaded each end for 1/4-28 to recieve a washer and Nyloc nut. I'm not an
aeronautical engineer so I cannot verify the benefit of this enhancement.
However I just wanted to confirm your comments.

| Subject: | Re: 912UL max and cruise RPM |
Did a little flying ad testing this afternoon. 5000RPM get me 3.7gph burn and 90mph
indicated which is very close to ground speed with 0 wind. I had not tried
WOT in straight and level. I am able to over rev the motor. I hit 5800 and about
110 mph. I say about because I had to back off to keep from over revving
the engine. I think I need to add at least a degree of pitch. I read somewhere
that to prolong the engine life of a 912ul one should not rev higher than 5500
even on climb out. I will add the pitch and see what happens.
I am looking at a set of the PVC strut fairing now.
Keep the good info coming.
Thanks
