<DIV><FONT face=Arial size=2>I had it on my Aries till it met an untimely death
by collison with the swamp in Nedeland.</FONT></DIV>
<DIV><FONT face=Arial size=2>If was kind of errie to say the least. Much
like and electric setup. It did not spool up or unload like the
smaller props.</FONT></DIV>
<DIV><FONT face=Arial size=2>On the verticals at 5/8 to 3/4 throttle and then
advancing to full throttle to did not accelerate but the extra 1/4 throttle
helped like in the avalanche or taller manuevers. Downlines were much,much
better then a 17x12 and landings are a piece of cake. I often found myself
advancing the throttle a tick just before the pull out of a downline. The
Mejlik is lighter the an APC prop so I didnt notice a lot of spool up
difference. Only drw back is the price of the prop and it takes the
right bushing to fit on the OS crankshaft. TRY it and I think you will
like it. When it gets warmer out I noticed it getting a little
warmer then usual so I opened th top end a click or two to richen it and that
seemd to help keep it cooler.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think as Mike Harrison has found with the 18.1
x10 apc wide blade that going to these larger props really helps with speed
control. He is I believe experimenting with a 18.5x9 wide blade APC.

<DIV>I've got a couple gallons through the new engine and I think
it's now properly broken in. The mid-range got a bit rich and clears
abrutply with a jump in rpm. I leaned the low end a little (from 12 to 1
o'clock position) and the downline braking disappeared. Speed control with
this set-up is difficult. With the low end a bit rich speed is
inconsistent on the horizontal lines but downlines are good. With the low
end a bit lean downlines are too fast but the horizontal lines are good.
</DIV>
<DIV> </DIV>
<DIV>I'm at 26.25" from the plug and turning the 15x11x4 at 8100rpm.
</DIV>
<DIV> </DIV>
<DIV>Is there any benift to lengthening the pipe further? </DIV>

<DIV><FONT face=Arial size=2>What is the length of you setup from the

<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>
