GF-9 (9cc/.55c.i.)

Glow Ignition Gasoline Engine

In 2019, the SH R&D team began developing the 9cc gasoline engine as a drop-in replacement for the typical .46ci size engine, designed to give superior reliability while using more affordable and commonly available gasoline.

To deliver consistent fuel flow in all flight attitudes, the SH team developed an easy-to-operate constant pressure pump fuel circuit designed around a crankcase-pressure driven adjustable fuel pump.

Today, we offer you our first pulse-type constant pressure pump system. Each 9cc gasoline engine includes this constant pressure pump system as standard feature.

  • Suitable for all 2-stroke .40-.55 size model aircrafts on the market.

The GF9 uses the SH Engines Glow Plug GT04 (#SEG040)
