Saito FA-120R3 Radial

Description

Saito continue to expand their radial engine line with the addition of the FA-120 3-Cylinder Radial. Ideal for 60-90 sized models, (you always loose a little power with a multi-cylinder; whilst gaining huge amounts of kudos). The FA-120R3 is an upgrade from the FA-90R3 engine, featuring 33% larger displacement and more power; all at a lighter weight for a higher power-to-weight ratio. The FA-120R3 also comes with a 3-piece flex exhaust system, making for an all-inclusive package.
