<DIV>In a 10.5lb EMC2 flying Masters, I seem to get a little more
than ounce a minute consumption. I am using the ES 2C140S90 pipe and a
APC/DL 3 blade 15.75x11 prop turning between 7600 and 7800 rpm on the ground
depending on heat and humidity. The sequence takes between 8 and 9 minutes and I
use between 9 and 10 ounces of fuel depending on how windy it is and how
often I need to use full throttle. I would say your fuel consumption is a bit
high but it may be due to the engine not being fully broken in yet. </DIV>

consumption, OS 140.</DIV>
<DIV><BR></DIV>
<DIV>Just getting past the break-in period for an OS140 and find the fuel
consumption a bit high...8-9 min on 16oz(in windy conditions). I'm using 15%
Cool Power, 15x11x4 APC, Aeroslave pipe at about 28". The high end needle
is 11/2 turns out. My older 140 runs closer to 3/4 turns out and will
give 11-12mins on the same set-up(except the pipe was 1"
longer) with no noticeable difference in performance.</DIV>
<DIV> </DIV>
<DIV>Is this normal for the newer engines or will the "mileage" improve
as I continue to run? </DIV>
<DIV> </DIV>
<DIV>Does the pipe length significantly impact the fuel usage?</DIV>
<DIV> </DIV>
