Features
Almost total freedom from vibration
Relatively low noise level Pleasant sound
specific to a rotary engine
Compact shape which enables easier
installation in most models
Commercially available top-quality model
engine fuel containing 15% oil, either
synthetic or castor, can be used.
Note
Do not use commercially available low oil
content fuel.
Start the engine by an electric starter. Hand
starting is very difficult as the mixture does
not access to the glowplug easily because
the glowplug exists in the housing, not
protruding into the combustion chamber.
Starting is difficult when the atmospheric
temperature is below 10 C.In this case,
warm the engine to approx. 20 C.
Since this is a rotary engine designed for
model application, there are some notes to
be followed in order to run it well for a long
time. Also, handling of this engine is some-
what different from that of two-stroke and
four-stroke engines.

When the engine is enclosed in a cowl, be
sure to make ventilation holes (outlet hole
Should be lager than inlet hole.), or the
engine will overheat, which results in poor
engine running or seizing in worst case.
Prime the engine fairly liberally with fuel and
turn the propeller more than 3 turns so that
all three chambers are primed. Start the
engine in a short time (1~2 seconds).
Prolonged application of an electric starter
(more than 4 seconds) without engine firing
will cause seizing between the side housing
and the rotor due to insufficient lubrication.
(Without firing, the fuel does not have
sufficient lubricating as the oil in the fuel is
diluted with methanol and additives.)

Try to set the needle-valve with one trial.
Setting on the ground lacks sufficient
cooling, and the engine easily overheats.
Do not remove the carburetor air funnel, or
the engine setting may vary, which results in
poor running.
