RE: sig somthin' extra
It may "fit", but I think you'd be setting yourself up for trouble. it's most likely going to be nose heavy, need taller gear for prop clearance, and (when balanced) going to need some VERY dilligent throttle management. Most people find them nicely powered with a .46 - .53 2 stroke or a .70 - .82 4 stroke. You may be able to make it fit, but I wouldn't advise using it.
