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)

Required: 12x6 or 11x7 propeller (use with ALL safety precautions, propellers are dangerous), gasoline and enough synthetic two-stroke oil to create a 24:1 mix, glowplug connector (note 1/4-turn lock connectors will not fit) with power source (1.5v), gasoline compatible fuel line, 6oz fuel tank that is gasoline compatible.

Recommended: We tune the gasoline engines to specific rpm, thus we highly recommend a tachometer, Electric starter. It makes starting much easier and faster.
