Saito 91S / 4 Stroke

Built for horsepower, the .91 still uses the same case as the FA-65/80 but puts out a whopping 1.7 hp. Famed Radio Controlled Modeler columnist and engine guru Clarence Lee calls the .91S "a real stump puller...". Compared to popular competitors, the lightweight AAC 91S wins the power-to-weight ratio contest hands down. You will be astonished at the power, reliability and smoothness of this engine when you see it for yourself.

If you want blazing performance and that 4-stroke purr for your model, you need the Saito FA-91S.
