I'm looking for an engine for a 120 size 3d plane. I'm thinking of buying used and it seems like there are a lot of Saito 180 engines out there that are used, More then other engine brands. Is this good or bad? I have never owned Saito engines but most people I talk to like them. I own OS and YS engine (both I like very much) how will the Saito compare? The people I know with Saito engines only have them on scale war birds and trainers, so I never get to see them in true 3d action. I love my YS 110 it has so much power with a great throttle response! Will the same be true with the Saito?
