frequent reason of engine damage or erratic
function.
Avoid contact between battery or radio wires and
•
rotating parts.
To stop the engine, close the throttle and stop the
•
fuel flow by squeezing the fuel pipe while the engine
is idling.
When starting the engine, avoid flooding the engine
•
with too much fuel, as it can damage the engine
with hydraulic locking. If the engine is flooded,
remove the glow plug, interrupt the fuel flow and
spin the engine by hand to eliminate the excess fuel.
Cover the engine head with a cloth to avoid fuel
from spraying out into your eyes.
When the piston is near to top dead center
(TDC) and in cold conditions, it can be
difficult to spin the engine. This is normal;
the liner has a slightly conical shape which
attains perfect geometry when the engine is
running at optimal temperature.

GENERAL INFORMATION

FUEL
Only use fuel specifically formulated for RC car engines. This
type of fuel is generally available in model shops and contains
a nitromethane percentage ranging from 10% to 25%.
During engine break-in, use fuel with 16% nitromethane
content. Once the break-in procedure is completed (and only
if needed) you can use fuel with higher nitromethane
content.
Be aware that high nitromethane content improves engine
performance but also affects the glow plug and engine
longevity.
Warning! Typical model car fuels are
toxic; avoid ingestion and contact with
the eyes.
