Safety Notes
Please remember the turbine engine is not a toy and has the potential to
cause bodily harm to you and others if misused.
The following guidelines should be read carefully and adhered to.
1. Always keep a CO2 or similar fire extinguisher close when starting
and operating the engine
2. Always protect eyes and ears during the starting procedure.
3. Be aware of the extreme intake suction hazard, we advise the use
of a suitable commercial wire mesh Foreign Object Damage guard to
protect the engine intake. Ensure you have no loose items of clothing
(ties, etc.) or equipment which can readily be sucked into the engine
intake, even from adjacent to the engine.
4. Always operate your engine in open air away from confined spaces
as the engine exhaust contains gases which can cause asphyxiation
and nuisance smells.
5. Do not touch the engine whilst it is running. Turbines rotate at a very
high rpm and the engine casing and exhaust can reach very high
temperatures. Ensure anything affected by heat is kept well clear of
the engine and exhaust during operation.
6. Never use the engine near to sources of flammable gases, liquids or
materials.
7. Keep unauthorized persons, spectators, children and animals well
away from the starting area (at least 30ft or 10 metre away).
8. Always handle turbine fuel and oil with care as they are highly
flammable. Store them in appropriate label containers. Never dispose
inappropriately. We recommend the use of suitable disposable
protective gloves for the mixing of turbine oil/fuel.

Warning
Higher loads occur when driving an R/C aircraft model with a turbine engines
compared to equally powerful drives like propellers or impellers.
This is a result of considerably higher air speeds caused by jet propulsion.
Maximum speeds under jet propulsion can exceed 200 mph, depending on
the model. We would like to remind you that the AMA has issued strict rules
regarding maximum speed for operating turbine powered RC models.
Please refer to the AMA regulations from the link posted above.
During installation, seal the intake and nozzle, as well as kerosene joints to
keep dust and debris out of the engine.

LEADING JET TURBINE Co., Ltd. ATJ TURBINES 8
Before starting the engine
1. Fuel and fuel tank, pump, shut-off kerosene valves , all cables and
turbine engine must be checked for correct.
2. All loose parts in the intake area must be fixed in a way they can never
be sucked in. Loose parts or dirt can damage the turbine engine. We
recommend use of a FOD screen.
3. Have a fire extinguisher (CO2) within reach!
4. Use only Jet A-1 or kerosene or Diesel with a 5% ratio of oil ( fully
Synthetic turbine oil). We recommend “Mobil Jet Oil II “
5. The Fuel system must not be leaking.
6. Start engine must be into the wind.
always keep the turbine with the nozzle facing downwards right before
starting.
7. Charge engine battery.
After shutting down the engine
Move jet model with the nose facing the wind. Wait until the cooling down
process is completed, it will take few minutes depending on the outside air
temperature.
The cooling process after engine shut down. During this process, the
electric power supply of the receiver and the ECU must not be turned off.
Do not touch the turbine during the cool-down because the danger of burning
still exists.
All tube connections must be inspected for leakage after each flight. The
fuel tanks must be emptied in case of extreme outside air temperatures or
when there is no further operations planned for the day (danger of
explosion!).

LEADING JET TURBINE Co., Ltd. ATJ TURBINES 9
Installation turbine engine
1. The engine should be mounted using the ATJ engine mount or an
approved equivalent. The securing strap should be tightened gently so
as not to mark the engine casing.
2. Fuel FASTO fitting should be routed similarly clear of the intake.
3. The fuel pump should be mounted at least 300mm away from the front
of the engine. The pump can emit electrical pulses that cause the speed
sensor to transmit incorrect rpm information to the ECU. The fuel pump
should be mounted with the spindle in the vertical position with the
motor uppermost. In the event of any fuel seeping from the pump this
will not pass through the electric motor. Note the pump is supplied
fitted with built in suppression to reduce radio frequency noise.
4. The centre of the fuel tank should be mounted laterally, as near to the
centre of gravity (CG) of the model as possible. This will minimize the
CG shift as the fuel is used during flight.
5. Any air ducting to the inlet of the engine must have a minimum area of
95mm square.
6. If an extended exhaust duct is required, it should be approved by ATJ
turbine. We have found that an exhaust over 90 mm diameter gives
optimum engine performance, base on turbine engine thrust and size.
7. Extreme care should be exercised to ensure that no foreign object,
loose parts of the model. Or debris is allowed to enter the compartment
where the engine is installed.
We recommend testing the engine on a test stand prior airframe
installation. You should have a clear idea of how to arrange the
components needed to run the engine. The main issue is the fuel tank,
you will need to arrange the CG in the centre of the tank and adjust the
receiver and ECU batteries to achieve the correct location.

Lower your throttle trim and the green LED will go out indicating correct
reading of
The transmitter engine shut off signal by the ECU.
On rare occasions, usually when using a Futaba transmitter, it has been
found that the
throttle channel sense of movement may require reversing (Servo reverse)
and repeat the transmitter alignment.
Correct reading of throttle % by the ECU can be verified in the second
screen,
percentage of the throttle position is shown on, 0% in the position of
engine stop (trim and stick down), 100% with stick/trim full up and
between 10% and 30% at idle.
This now completes your radio setup and should only need doing again if
the radio settings
in the TX are changed.

First Turbine Operations (starting engine)
Initial steps
1. Fill the fuel tank with jet turbine fuel, include 5% turbine oil mix.
2. Make sure the tank breather is open, no bubbles in fuel system.
3. Filter your fuel when filling up using a line filter on your carry fuel tank.
4. Make sure that both the ECU battery and the receiver battery are
charged and in good conditions.
5. Test your remote control range with and without the ECU turned on.
6. Always place the jet aircraft with the nose into the wind and make sure
that the jet blast will not be set in the direction of persons or equipment.
Prime the Fuel Pump feed the fuel into engine first time.( page 21 )
Turn the transmitter and the receiver ON.
Turn the engine main power ON
Set the throttle stick down and the
trim up. “Idle” - Confirm that the
LED in the ECU is illuminated and
the screen shows "Ready" - !
Move the stick to 100% and then
back to idle again. Do not leave the
stick at 100% more than 3 seconds.
The ECU will automatically check
the glow plug circuit and if OK
energize it, wait 10 second then
apply power to the starter and open
the gas solenoid. In the screen of
the ECU it will show the word "Ignition"
The gas will ignite. You will hear a "flame sound" confirming this, the
temperature indicator in the screen of the ECU will begin to up.
When the ECU detects an increase in temperature of 80~100ºC from the
temperature read at the moment the start is initiated, the screen will
change to "preheating". The fuel pump will begin to operate and power to
the glow plug will be disconnected.
Next the screen will change to "Fuel ramp". In this phase the ECU will
be gradually increasing the starter power and fuel flow. When 18.000 RPM is
reached the ECU will automatically disconnect power to both the starter and
gas solenoid valve. When the rotor speed reaches idle, the screen will
change to "running" and the engine speed stabilized.
