Hi all, does any one have any advise on props, my kr2 has now had its second
test flight on it, The prop is a Tonini gt, its a 56*44 and i am only getting
2800 rpm on climb and 2900 at 140 Kts. (160 mph) Revmaster claims full power is
85 hp. @ 3200 rpm. the climb also appears to be lacking. engi

my KR will have a revmaster 2100D.
I have a Avid mark IV now with a revmaster 2100D with a 60x28 and will
turn 3000 static. I was told the prop would be 400.00 plus shipping. that's
what I paid

Each inch of diameter you take off will gain you 100 RPM. Minimum static
RPM on the ground, for a VW, is 2900.

52" is not too short for a VW - KR combination and much more simple than
re-pitching.

Boy, time flies. Looking in my logbook I see it was October 2010 that I
flew up to see Paul Lipps - not "a couple years ago" as I said previous
post.
Paul mentioned that Roy Marsh, over 90 years old, was still showing up
for the local chapter EAA meetings and still prowling around the airport.

That R-2300 sure seems like an ideal engine for a KR - designed to get
it's power at lower RPM. This is ideal for a number of reasons. The
higher the RPM the more heat is generated from friction and heat, besides
being totally wasted energy, is the VW's worst enemy. I have a friend
who went thro
Wooden props can be de-pitched. I would do this first before shortening. Peter
You do seem to have too much prop. 56" seems a bit long to me on a KR
with a VW, but I have no idea what your gear setup is and how much prop
clearance you have. 52-54 is in the more normal range for a VW powered
KR.
I would get with the maker of your prop for a recommendation as to what
should

160 mph isn't bad at low RPM, but with a CG that far forward, yes, you'll
need
