Jim,

A 25cc gasser is not going to allow the Super Stinker to perform up to its full aerobatic potential. However, for general flying around and basic manuvers it would probably work. At 14 lbs of thrust you would be right at 1:1. Personally, I would shoot for 1.5:1 or 2:1...(21 to 28 lbs static thrust) but that's my style. Does Brillelli offer a gasser in the 40cc range?
