All,
update to my Husquvarna 88cc ,5.3 cu in conversion. I have successfully flown my first 33%, gas powered H9 Extra 330L powered with this engine! swinging a (for now) zinger 26x10 prop at roughly 6200 rpms, it hauls this 27lb (roughly) bird into the air. performs nicely! not unlimited by no means, but hauls it enough to do imac. Im amazed at how it runs now! 3 flips with choke, then about 5 flips just about every time so far and she is running!

thanks to Ken Lambert for the muffler, Mark Levings for the Husky, and CH for a very well running ignition system!
