<DIV>In my book the Dave Lockhart 3 blade at either the 11 or 10 pitch is the
way to go. Very constant speed, uphill tractor like pull, very slow down line
braking and extremely quiet. Right now I prefer the 11 pitch on my EMC2
and Focus 2. With 20% I see 7600 ~ 7700 on the ground with an ES 2C140S90
pipe. If you want to try a Dave Lockhart 10 pitch 3 blade I have a
new one that was mounted but not run. </DIV>

<DIV>Just did some checking - baffle is at 27inches. I ran the airplane today
in 32deg C and windy conditions. The 15.5x12 4B was way too much load (at
least at that pipe lenght). The plane practically stops on the top corners.
I'm looking for 15x11 4B but can't find any...I don't think they are still
made.</DIV>
<DIV> </DIV>
<DIV>How does the re-pitched 3 blade compare? Overall speed, upline
performance and downline braking.</DIV>
<DIV> </DIV>
<DIV>Where can I get one?</DIV>
<DIV> </DIV>
<DIV>Has anyone tried re-pitching 15.5x12 4B to 15.5x10?</DIV>

<DIV><FONT face=Arial size=2>What is the length of you setup from the plug
to the baffle inside? If I remember right the baflle is 15" from the
inlet.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Mine is at 26" from the plug and I finaLy was
able to get a real good down line braking and richen the low end
out. The Aeroslave pipe will make a ton of power in a
shorter length but the engine gets peaky and will come on the pipe or
really unload. One thing about this pipe. If it is
burbly rich in the midrange the length is too short.</FONT></DIV>

<DIV>Worked like a charm!!</DIV>
<DIV> </DIV>
<DIV>The engine ran flawlessly on the first flight after the run-in. I'm
using the Aeroslave pipe and 15.5x12 4 blade. I'm about 1 3/4 out with
the high end and parallel with the cylinder for the low end screw. All
seems OK.... good/slightly rich top end, reliable idle, rich in the
middle but accelerates with no problem, good downline braking. When
should I start moving the low end screw and where will the final
position be ...typically?</DIV>

<DIV><FONT face=Arial size=2>I am going to write a full "care and
feeding" article for the OS 140 for the July K-Factor, but here's a
good start.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>First, set your low end screw parallel
to the cylinder. 12 o'clock, straight up and down. leave it there
for the duration of the break in.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Use an APC 17x10N prop. use an OS F
plug.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>back the high end needle out 2 full
turns. if you plane has a chin cowl, remove it. This engine gets hot
for the first run or 2 on the ground.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Crank the engine with a very high idle.
Remove the igniter and then advance the throttle to full power after
about a minute. It should be spitting rich.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Turn the high end needle until it gets
some good RPM but still very rich. You should be putting out some
serious smoke. let it run this way for about 5 minutes, no
more.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Shut the engine off, and let it cool
for about 1/2 hour. the more, the better.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Fill the tank, crank it again, run it
to full. This time go in on the needle about 2 clicks and use that
for the reference. About every 30-45 seconds, lean it until it goes
to max RPM, and not ANY further. Let it run this way for about 5
seconds, and richen it back up. Cycle it this way for about 7
minutes. Shut down the engine, let it cool again.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Crank the 3rd time, and run it at the
same setting for about 2 minutes. Now lean it a couple of more
clicks, and it should be still putting out some serious smoke, but a
little closer to full. Step back, and let it run wide open for a
minute, then begin throttling it back and forth every minute or so.
Run the tank out like this.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>put it together and go fly it. Don't
touch the needle. When you get to the bottom of the 1st gallon, go
in with the needle ONE click every flight until you get max power.
When your low end changes, set the low end (always more lean, but
not a whole lot. When you play with that bottom end, a little goes a
long way. Like 1/8 of a turn or so.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There are a lot of diffferent ways to
do it; some people just set it rich and fly. This way works every
time though, and the engines last longer.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>have fun,</FONT></DIV>
<DIV><FONT face=Arial size=2>-Mike</FONT></DIV>
