<DIV><BR></DIV>I really hate to do this to myself but I think that I owe it to
all the people that offered an opinion to me about my engine. The engine
has been idling at 2150-2200 all along. The tach that I was using was
taking a really long time to settle down. It had been a while since I
had used it. I had a friend help me at the field before I went drilling
hole and what not. When he put the tach on the engine he waited a little
bit longer than I was apparently and the engine or actually the display on the
tach dropped right into line. Come to find out the battery in the tach
was very very low. I replaced it and now the tach reads pretty
quick. So I guess all that to say I am a big DUMMY.<BR><BR>I thought
that I would share this as a little humor. Again thanks to all that gave
there input.<BR><BR>See you all at the next contest.<BR><BR>Dan<BR><BR>John

<DIV><FONT face=Arial color=#000000 size=2>That is the first time I have
heard of that much prop on a Sport 140. It is way too much prop for
break in of a new engine. I don't know if there is any damage due to
that load. I use about 40 ounces of fuel on tat engine to break it in
with a 15-10 prop at about 8200 rpm. </FONT></DIV>

<DIV><FONT face=Arial color=#000000 size=2>I feel the bigger prop
will generate more heat and will need more latitude for

color=#000000 size=2>(not DZ!) more nitro is needed. There is more
oxygen available in the higher nitro fuel so you have a wider needle
available.</FONT></DIV>

get out of a 17-10 with 20% fuel?</FONT></DIV>
