I am thinking about switching to gas a engine. I fly mostly 90 to 120 4c engines now. Is there a reasonable gas engine in that size range you experts can recommend?

This question would be better in the giant engines forum. I am looking for the same type of thing, and there is a thread in there. The rcs 140 seems to come up as a good engine for a 120 sized plane, but since I don't even own a gas engine, post in the giant engines section, they will be alot more help. Good luck

Will do.
