<DIV><FONT face=Arial size=2>Brett,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Assuming you like the AC and it is running well, I
would leave it alone as Ed says. If you swap to a 2C, you may have some CG
issues to work out - especially depending on what exhaust system you are using
now with the 4C and which one you choose for the 2C.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For 2C choice, in the northeast, we've not seen
many of the Mintors, but we've seen them run well at the NATs. I'd not go
with the OS160 because is heavy (but cheapest and plenty of power and
reliability). To me, the choice is really between the 140RX and the
Webra160. And the bottom line is that you be able to pretty easily setup
an OS140RX to give good power, good throttle response, and excellent
reliability. With the Webra, it will take some setup time and more
attention is needed to keep the Webra in the "sweet" spot and then it makes tons
of torque and power more efficiently (less fuel) than the OS.</FONT></DIV>

<DIV>Leave the AC in there. With a few tricks and 25 to 30% nitro you can
swing a big prop in the high 7's to low 8's quietly and have more than enough
power. </DIV>

<DIV><BR></DIV>Dave,<BR><BR>I have a YS 1.20AC (I think) with a Hatori pipe
in my 2m plane. If I were to upgrade to a new motor I would strongly
consider 2-stroke for the price factor alone. I think the YS 1.60
looks like a tremendous motor, but it is a lot of money in upfront cost as
well as fuel. <BR><BR>What would you recommend? The plane weighs
10#4oz now. Should I look at the OS, Mintor, or Webra?<BR><BR>Just
curious,<BR><BR>Brett<BR><BR>
