wow...thanks for the insight. i have been going by mostly other peoples word on that and a few poeple with experience. i guess i wasnt considering the 36-40cc range and more of the 20cc-26cc range for a 90 size plane which i have heard are heavy for the power they put out. i have flown a members funtana 100 with zenoah 20...great plane but not the punch it needs....i guess its more that there might not be a good gas engine for a 90 sized 3d plane and i wasn't taking into consideration the planes between 90 size and 50cc ( which i know there are a bunch it was just a bit neglectful ) thank you for mentioning this because i did not by any means want to steer him in the wrong direction.

my opinion still stands about a saito 220 being better tho for this sized plane.
