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><div><span class="gmail_quote">On 3/2/06, <b class="gmail_sendername">David Lockhart

<br>the folks at YS Performance provide great service to the YS faithful. And<br>to get solid performance, you need only to slap on any one of a number of<br>headers and mufflers at pretty much any length, dump lots of 30% nitro low
<br>viz oil fuel, bolt on a prop that will hit sufficient RPM to bust the<br>noisemeter at 80% stick, and set the needle. Good power, good torque, and<br>nice throttle curve are the likely result - along with plenty of noise and
<br>vibration (relative to a 2C).</blockquote></div><br>
