FA-40A 4-Stroke Engine (SAIE040A)

The FA-40A 4-Stroke Model Engine is a compact, high-performance powerplant designed for RC aircraft. This four-stroke engine can drive a 10x4 prop at 10,500 rpm, delivering the distinctive four-stroke sound and smooth torque that modelers expect from a modern, small-scale engine.

With a smaller case design for lighter weight, it sits in a size close to a .30 but delivers more punch. Built with Saito craftsmanship and backed by a standard 3-year warranty, the FA-40A is a reliable, power-packed option for pilots seeking efficient, scale-true performance. A Golden Knight edition is available, featuring a gloss black case and gold-plated rocker covers.
