At 876 lbs empty I'd be looking for a bigger engine than a VW - especially at
that altitude and with those temps. Also, I'm pretty sure 3,000 rpm is a bit
low - most of the VW guys seem to go for around 3,400 - 3,600.

I have a 54/48 on the front of a 2100 Revmaster in my 2S. I originally had a
54/50 but wanted a better climb so I had it repitched. I'm 3000 static and was
just slightly less before the repitch. Cruise speed (135 mph ) at 3300 didn't
really seem to change much.

Just bought a Sporty's SP400 for $315 and am playing with it. Seems well
made. Has all the Nav/Com features plus ILS, VOR, and OBS capability along
with CDI. Doesn't list any of the restrictions you guys are talking about,
including the ability to transmit and receive when plugged in / charging?

What do you want for that engine? What does the cowl fit?

Pierre,
Your first prop was closer to what you need, but quite honestly, you just don't
have enough engine to turn the prop at that density altitude. People get all
wrapped around the axle about pitch, but tip drag is also a big issue. You
don't say what the displacement of your VW engine mig

Wow. I never read the directions to my ICOM A24 handhelds. They both have been
plugged into the chargers in the hangars for at least 5 years. If I need to
talk to someone, I pick them up and transmit while still plugged in. If I need
to go mobile, I unplug them and go. The units and the batte
Trutrak is doing something completely different with this model autopilot.
Instead of having a servo attached to your control rods or cables, it uses a
tiny tab with a fast acting RC servo hung off one aileron and the elevator. Of
course one could skip using their add on tabs and build a smal
General rule, a reduction in diameter of 1" (1/2" taken from each blade)
will yield an increase in rpm of 100 rpm. So take that original prop down
to 50" diameter and you will have your 2900 rpm. That's an easy mod to do,
just re balance it and you're done.

All,
Thanks for your responce, I opened a question with my request at the woodcomp
factory, hope they can help me to make the decision. The 3 blade is nicer but
probbably not the one for my kr-2s
Have a good cristmas to you all.

Hi Guys,
It feels as if I've hit a brick wall. I had a 48(pitch) X 52 prop on my KR2S
(haven't flown yet). The max revs I got was 2,760rpm static.
I then bought a 45(pitch) X 54 prop to see if I can get to 3,000rpm, but I
only got to 1,850rpm. Stripped the 2 Stromberg 175 cd carburetors and h
I never had a problem cooling my Type 1, once I put on the Revmaster oil
cooler. The oil cooler on top, is not enough for a 2180+ VW. Works great
on the 1835 and such, but not on the larger displacement engines.

Pierre,
Hate to say this, but I don't think this plane is going to be safe to fly as
is. If you are truly at 5500 ft, and empty weight is 876, the VW is probably
not going to be enough engine. Specially at the temperatures (89 -108) you are
stating.
Your 1st prop was closer to what you nee

Obviously, top RPM is 3450 or so, not 2450 or so. Also, I should
mention that I'm now flying a "52x54" Sterba pro

Depending on the displacement of the VW engine, you likely need less
pitch (as others were quick to point out). The way the prop maker

If you want a good engine for that heavy KR, I have a Roy Szarafinski
Corvair complete except for the exhaust. I mean complete with Ellison, prop
and spinner. I will throw in the slightly damaged cowling as well. I want
a bigger engine for my Panther.

What engine do you have?
It seems you decreased pitched and at the same time increased length.
Increasing length, decreases RPM with the same rated horsepower.
Similarly decreasing pitch, increases RPM.
Shorten the either of the props and you will see a significan
