WhOO hOOO!.............put a new tank on, new lines, new filter, added a couple ounces of klotz syn. 2-cycle oil to my gallon of cool-power 15%, and this ys engine is running like a scaret cat-burgaler!!!!!!!!!!!!!!!!!! It's supposed to be a balmy 37 degrees here in MI sat., thinking about flying for the first ( or maybe it's the 2nd) time this year. I don't know if I'll try to hover, maybe just get the thumbs loosened up again, and the engine/plane tweaked in (no, I'm not going to lean the ys too much till I at least get a gallon through her, then still, not TOO much). But I AM looking forward to this season more than I ever have, since 1999, the year I soloed with my sig kadet lt-40 (r.i.p.).................I need to order my feul for the year the 1st of march, anyone recomendations? I was either going to get wildcat ys 20/20, or some wildcat 30% syn. heli feul, or a combination of both, depending on $
