GF-6 2-Stroke Electric Ignition Gasoline Engine Manual
(for .30 size Aircraft)
The SH R&D team started developing the mini gasoline engine back in 2009. The purpose was to respond to
the challengebetween high nitro fuel costs and the difficulty of obtaining it in the market. The goal was also to
improve the inconvenience of carrying bigger size engines for car, aircraft and boat applications. SH finally
launched the world’s first 5.1cc (GC31) high performance gasoline engine for 1/8 scale use in 2015, after
years of experience and major breakthroughs.
The SH Team overcame the common problems plaguing existing gasoline engine in the RC market; including
high temperature, low speed and so on, during the research and development period. Not only were exclusive
designs from world patents applied, but SH also combined CNC high-tech processing. Here SH has
successfully produced a small displacement CDI ignition gasoline engine with their persistent efforts and
continuous improvements.
Although the GC31 CDI ignition gasoline engine series achieves the performances and effects as expected,
it still couldn’t get rid of the defects from the CDI igniter; such as increasing weight, space limitations during
installation and high voltage interference, with some other trouble challenges. Therefore, SH continuously
tested and finally made a breakthrough, officially releasing the electric ignition gasoline engine (GC31 SPEC2)
in 2017. According to the demand of the aircraft market, the world’s first 6cc 2-stroke electric ignition gasoline
engine (GF-6) was produced in the same year, at the end of 2017.
GF-6 gasoline engine comes with great power, high speed, lasting life, operational stability, easy
adjustment, excellent cooling and economic fuel consumption! That’s why we strongly believe it will be the best
choice for all the aircraft pilots.
●
Suitable for all 2-stroke .25-.40 size model aircrafts on the market
●
Proper run-in (break-in) of the engine is a very important step in ensuring that you get the
highest performance and lifetime of your engine.

The igniter spec as same as the standard
nitro engine
Propeller size of
10”x6” as
suggestion

above picture showed
(spin the engine shaft counter
clockwise direction to the piston
compression angle, and fixed the
propeller angle at 45 degree)
ATTENTION
●
An inappropriate (too big) propeller may cause the engine to become overloading, and
potentially shorten its life.
●
Please make sure the propeller is tightly locked in case of any issues occurred by an
accident.
250ml engine oil can be mixed with 5
liters of gasoline or 80ml engine oil mixed
with 1.6 liters of gasoline. (1600/80=20)
1. Please make sure the engine is mounted to your model securely and that the fixed screw is locked
tightly to the carburetor in case of any issues causing unsmooth performance.
2. Use a mixture of 92 Octane gasoline and SH
specified 2-cycle oil.
Suggestion: the best gasoline and engine
oil is 20:1, roughly around 4.76%
3. Plug: The engine is equipped with an SH factory
specified manufacture plug, with a 1.5A voltage
applied.
(the plug spec as same as the standard nitro engine).
4. Propeller: We suggest a propeller size of 10"x6" and
the installation angle recommend as the below
