Fuel Requirements
93 octane (or higher) automotive gasoline with 2 cycle oil added (7oz. to 1gallon
of gasoline).
2 Cycle Oil Requirements
Klotz 2 cycle oil: (7 oz. to 1 gallon of gasoline)
Klotz 2 cycle oil (or equivalent) can be found at most motorcycle specialty
shops/dealerships.
RPP 2 cycle high performance oil: (7 oz. to 1 gallon of gasoline).
Robertson Performance Products (RPP) 2 cycle oil is designed specifically for
use with gasoline-powered RC helicopters to provide the best
performance/thermal protection for your engine. RPP oil is available your local
hobby dealers or through:
Robertson Performance Products
Clairemore, OK
(918) 342-1133
It is not recommended that standard “lawn and garden” type 2 cycle oil be used as
this oil is designed for use at operating temperatures below that of the Zenoah
G23 in a helicopter application.
IMPORTANT FIRE AND FUEL SAFETY RULES
This model uses combustible and highly flammable mixed oil and
gasoline. Gasoline can explode and burn causing serious injury to you
and others. Be extremely careful and use common sense at all times.
• Never expose fuel to open flame.
• Do not smoke when fueling or operating model.
• Wipe up spills or excess fuel from model.
• Fuel only with a suitable gasoline manual fuel pump. Do not
attempt to fuel directly from gas container.
• Fuel only in well ventilated areas.
If an accidental fire does occur, use extinguisher or smother with a
heavy cloth. DO NOT use your cleaning cloth as it may be contaminated
with gasoline. If fire continues, call for help.
Pre-start Engine Carburetor Tuning
Your Zenoah G23 engine is equipped with a Walbro carburetor with primer bulb.
This carburetor has both a high and low speed needle valve for engine tuning.
Before initial engine start-up, adjust the needle valves as follows:
Low speed needle valve: Close and open to 1-1/4 turns
High speed needle valve: Close and open to 1-1/2 turns
Although these settings may need to be re-adjusted during test flights, they will
provide an acceptable setting for initial starting.
Please also note the range in which each needle valve is active as compared to the
throttle position:
Low speed needle valve: Idle through hover
High speed needle valve: Above hover to full throttle
Initial Engine Start Up
It is recommended that on initial engine starts that the main and tail rotor blades
be removed until it is established that the radio system range tests properly.
Start Up Procedure
1.
Locate fire extinguisher and have available at all times.
2.
Fill fuel tank with gasoline.
3.
Push primer bulb on carburetor to prime engine.
4.
Turn on radio system and verify that the throttle is in the low (idle) position
and that all controls function properly. Move throttle trim to 1/2 (center)
position. Next, close the choke lever located on the carburetor air cleaner.
5.
While holding the main rotor head securely and stepping on the landing
skid with your foot, pull the pull starter until the engine starts. As soon as
the engine starts it will be necessary to open the choke slowly or the engine
will stall. Re-start the engine if necessary until a reliable idle is achieved.
6.
To stop the engine, either move the radio throttle/trim lever to the off
position, or close the choke.
Before further engine tuning or initial test flights are completed, it is suggested
that engine off and engine on range tests be performed to insure proper radio
operation and safety.
Range Testing/Engine Off/Engine On
Range Testing
Due to the additional RF interference generated by the Zenoah G23 gas engine, it
is strongly recommended that range testing of your radio system be performed
with the engine first off, and then with the G23 engine running prior to initial test
flights. The following range testing procedure is designed for use with the
recommended PCM radio systems. As previously mentioned, due to the
additional RF interference generated by the Zenoah G23 engine, it is highly
recommended that only a PCM (Pulse Code Modulation) radio system be used
with the Ergo Z230.
Range Testing: Engine Off
Initial range testing should be performed per the radio manufacturers suggested
antenna down range requirements. For JR radio owners, the acceptable range test
distance (antenna down) should be approximately 100 feet.
Before initial range testing, it is suggested that the helicopter be placed on the
ground in an acceptable area for initial engine test starts. During the Engine Off
Range Tests, it is suggested that the maximum antenna down range be established
(the point when the radio system stops operation), and that position be marked so
that a comparison of Engine Off, Engine On Range Testing is possible. If your
radio system passes this Engine Off Range Test, proceed to the Engine On Range
Testing below. If your system does not achieve the specific manufacturer test
results, please contact your radio manufacturer before proceeding.
