Robinison 22HP Manual

Fuel 15-30% Helicopter fuel is recom-
mended containing more oil. Use a fuel filter
between the fuel gallon and the heli to remove
any dirt that could stall the engine. Fuel the
helicopter by removing the fuel line from the
carburator and replace when finished.
Needle Valve
Following the engine
manufacturers instructions, turn the main
needle valve until closed and open to the
setting the instructions call for. Different
engines will have different settings.
Radio
Always turn the transmitter on
first, then the helicopter & gyro and reverse
when finished, turn off the heli & gyro first
then the transmitter. If the radio acts errati-
cally or intermittent, find the problem before
starting the engine.
Glow Plugs
Using a glow plug connector,
remove the canopy or optionally use a remote
glow plug connector to heat the glow plug.
Warning!! glow plugs operate at 1.5V **not
12V.**
Engine
Before starting the engine, check the
correct direction of rotation and make sure the
electric starter is turning the same direction.
Starting
Start the engine from low throttle with
the trim centered. Holding the rotor head in one
hand, angle the starter and press down slightly to
engage the starting shaft into the fan. Start the
electric starter until the engine starts. If the engine
does not start recheck all previous points. The
main blades will not turn until the engine RPM is
above idle.
Stopping To stop the engine, with the throttle
stick in the low position, move the trim all the way
to the low position.
Starting Your Engine
First Flights
For the beginner pilot, a training pod is strongly recommended to assist in learining
to hover the helicopter with substantially reduced risk of crashing. These systems provide an on
ground training capability to allow pilots to become familiar with the helicopter before actually leaving
the ground.
Pitch
Once the helicopter is flying the pitch
settings have to be fine tuned. Using appropriate
training gear, increase the throttle until just before
the helicopter lifts off and sight the rotor disk from
15' back. If there appears to be 2 rotor disks then
adjust Pushrod J until only one disk appears. Using
colored tape mark one blade so you can adjust the
correct blade.
Adjusting the Blade Tracking
Q. The engine does not turn easily with the starter.
A. The starter battery may be too weak or the
engine is flooded. For flooding, remove the glow
plug and turn the engine over several times to clear
the combustion chamber of fuel and retry.
Q. The engine rotates and tries to start but doesn't.
A. The glow plug may be getting old. The glow plug
batteries are weak. The starter may be turning the
wrong direction.
If the Engine Does Not Start
Q. The engine just does not start.
A. The glow plug may be burned out. Fuel may
not be getting to the engine, check for a clogged fuel
line, dirt in the carburator or the main needle needs
to be opened out slightly.
Q. The engine starts but immediately stops.
A. There is a clog in the fuel line, the carburator is
not open enough at idle- open the throttle trim by
1-2 clicks. Helicopter engines have a low speed
needle which is factury set, beginners should not
adjust it!!
Before each flight, check that all bolts and screws are tight. Simply flying your helicopter, will loosen any
screws which are not threadlocked or secured with a lock nut.
