Saito FA-120R3 Radial Four-Stroke Glow Engine

Saito continue to expand their radial engine line with the addition of the FA-120 3-Cylinder Radial. Ideal for 60~90 sized models, 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.

Like all Saito engines, this powerhouse is engineered with that same Saito quality and reliability you have come to know and trust.
