Introduction

Congratulations on purchasing this

fine engine.

It has been over 20 years since Saito

introduced their first 4-stroke glow

engine, the FA-30. Since that time Saito

has led the way in the development of

powerful 4-stroke glow engines, from

the small FA-30 to the large FA-325

5-cylinder radial engine. Leading the

way in innovations, we have seen the

V-twins, and now Saito is proud to

introduce the 4-stroke gasoline-powered

engine.

Saito 4-stroke gasoline engines are

developed exclusively for model

airplanes. They are designed with

an emphasis on high performance,

durability and weight savings. Their

components are modified to adapt

to the gasoline version of existing

glow engines and are equipped with a

4-stroke gasoline engine carburetor and

ignition systems.

Remember, a properly cared for

engine will offer many years of

modeling enjoyment.
