Warning!
ALWAYS WEAR EYE AND HEARING PROTECTION.
Model engines throw out
oil droplets when running. It is nearly impossible to avoid getting oil on you while
starting the engine.
12. Move the transmitter throttle stick (left stick) to about ½ throttle, and the throttle
trim lever to full. Hold the rotor head with one hand, and tilt your helicopter on its
side with the right skid on the ground as shown in Fig. 4-1 and Fig. 4-2.
13. Spin the engine with the electric starter. Push firmly, but not excessively on the
starter cone as shown in Fig. 4-1.
14. The fuel line from the tank must be full of fuel before the engine will start. While
you spin the engine with the starter, ask your helper to hold a finger over the
carburetor inlet for one second. This will draw fuel from the tank into the engine.
You may need to repeat this procedure several times before the engine will fire.
Hint:
If your engine is new it may not turn easily against compression. It will turn more
easily after running for about 30 minutes.
15. If the starter slips on the starter cone, the piston may be hydraulically locked. Do
not force it to turn or you could damage the engine. Remove the heat sink and
glow plug and spin the engine with the electric starter for one second to clear the
excess fuel from the cylinder and crankcase. Replace the glow plug and heat
sink, and clean the oil off the starter cone and the rubber insert on the starter with
a paper towel.
16. If the engine refuses to pop, remove the heat sink and glow plug, and connect the
glow plug to the glow plug clip (be careful, it gets very hot). The entire coil should
glow bright orange (not visible in direct sunlight). If it does not, the glow plug or
glow plug clip may be bad, or the glow plug battery may need charging.
Hint:
All glow plugs have a limited useful life. When you suspect that a glow plug is
going bad, replace it with a new one. If engine performance improves, the old
glow plug was bad.
17. When the engine starts, immediately lower the throttle so that the clutch shoes do
not wear against the clutch bell. Be careful, if the throttle is set too high the clutch
will engage and rotate the whole fuselage (and tail rotor) toward you.
18. Remove the glow plug clip, and place your helicopter on its skids on the ground
so that the main rotor can rotate freely.
