<DIV>Unfortunately, had no header on this setup, so I can't answer. There
are others who have, bet they will. I pulled the 91 when I went nuts with
the ST2300.</DIV>

<DIV>Bob,</DIV>
<DIV>I'd be interested to know what pipe, header, lengths, props etc on the 90
two stroke. I'm building a CA models Zafiro with a 90 (Tower had a $25 off so
I bought a super tiger 90 for basically $95!). And am thinking of piping
it.</DIV>

<DIV>Forgot to add that I have # 2 here, and it is being configured with the
91 two stroke on a tuned system. It will be interesting to be able to
compare the two.</DIV>

<DIV>The 1.20 class two-strokes in this airplane will probably provide the
best power at the lightest overall weight. The ST is overkill, and
added about 8-9 oz overall more than should have been there, because it
starts out at 31 oz, then add the exhaust system. Most of the
1.20's, I think, are coming in at 31-33 oz WITH exhaust systems, and that
reduces wing loading about 2 oz/sq.ft.</DIV>
<DIV> </DIV>
<DIV>I'm ready to test hop, awaiting the header, which is in
process. It is surprising to see this one design catch on so
rapidly. Was it price? Performance?</DIV>

<DIV>Bruce,</DIV>
<DIV> Thanks, that's what I am concerned
about. The OS 91 FX most likely will require a pipe to do the
job and the Excelleron</DIV>
<DIV>is not set up for a pipe. I may have to resort to a larger
2 stroke engine. Bob Pastorello is using a Super Tiger
2300.</DIV>
<DIV>Not sure I wish to go that big !</DIV>
<DIV>Thanks,</DIV>
<DIV>Paul</DIV>

<DIV>I have a scratch built Typhoon 909 that weighs around 8 to 8.5
pounds. The "Littlephoon" has 909 square inches of wing, about
a 70 inch wing span. I fly intermediate at 5500 feet
MSL. The YS91 did not have enough to fly the Int pattern,
because of the two maneuvers you mentioned. I put a YS 110 in
the Littlephoon, and now I have plenty of power swinging a
15X8. I have no experience with the OS, but I would think the
YS would be a little lacking. </DIV>
