There are two very long threads on both the kit and ARF version of the Sukhoi. All are very good with a lot of information on this model.
A 1.20 four stroke is the minimum suggested engine, or about 20cc.
Yeah, i've got em in my fav. list. read pretty much every post and a lot of guys say 1.20 4 isn't enough. 1.5 is nice. you not think so?
anyway, i appreciate all input because, well, i've never flown this plane, never seen one fly, etc. just trying to get a good idea of what will be a nice setup!
