<DIV><FONT face="MS Sans Serif">I currently use this engine in my quarter scale G.P. Patty Wagstaff. Plane is about 15-16 pounds and will hover at less than 1/2 throttle with unlimited vertical with a 22x10 prop. Very happy with this setup. Can't imagine trying to cram all the stuff that goes along with this engine in the current pattern aircraft. And I think you would have just too much power up front. Vibration could be an issue. Also clearance for the 22" prop. The Patty has plenty of room in the cowl for the engine, battery, ignition and all of the associated plumbing. </FONT></DIV>
<DIV><FONT face="MS Sans Serif"> Also have the same engine in a 1/3 scale G.P. Pitts. Again plenty of room under the hood for everything. </FONT></DIV>
<DIV><FONT face="MS Sans Serif"></FONT> </DIV>
<DIV><FONT face="MS Sans Serif">On both aircraft the head sticks out of the cowl a good bit. Plus the plug and ignition wire are exposed as well. </FONT></DIV>
<DIV><FONT face="MS Sans Serif"></FONT> </DIV>
<DIV><FONT face="MS Sans Serif">Good luck. </FONT></DIV>

<DIV>The weight with ignition of 3.37 lbs looks really good for a 2C gas engine. That's without a battery ofcourse, but it's still pretty good. It's a 48.5cc design, with recommended prop sizes (non-pattern use of course) in the 2B 20x12 range and an RPM upper range of 7800. Those are for stock muffler setups no doubt.</DIV>
