Hi Guys,

I'm a relatively new flyer (about 9 months). I've flown my trainer with a 2 stroke, Four Star with a OS 91 FS and my Somethin Extra with a OS 70 FS. On the table now is a CG Ultimate. I've been trying for a month to decide which engine to get for it. All I know is that if WILL be a 4 stroke. I've heard good things about the 120's (OS, Saito etc) but the engine rumored to give all out performance is the YS 120. Even the plans show a YS 120 in the nose. So here's my question, is the YS too much trouble for the average sport flyer? I fly a day or two a week usually. I enjoy the hobby but am not competition oriented at all. I just have fun. With all the tinkering I hear YS's need, and the pressurized fuel tanks potentially giving some trouble, is it a wise choice for an average flyer? Would I be better off with a "normal" 120 - OS or Saito?

Sorry for the long post, I just wanted to give you all the background for the question and why I'm asking.

Who's flying the CG Ultimate and what engine are you using? What performace are you getting?

Best,
Harold
