carefully and push the off button to stop as soon as fuel reaches close to the engine. Best too short than risk flood the
engine.
IMPORTANT: The prime procedure should be done only to fill the fuel tube and filter in the case of a first
installation or in case of disassembling of the tubes. It does not need repeating. Pushing fuel directly into the
engine will cause an uncontrolled fire at next start-up.
Starting the engine
Set the throttle stick down and the trim up (“Idle”). Confirm that the screen shows "Ready" ie Ready to start! In the
case that the exhaust temperature is over 100º, the ECU will power the starter to cool down the engine. Wait until the
cooling sequence finish.
Move the stick to full throttle and immediately back to idle again within 2 seconds. The ECU will begin the start-up
sequence as described below:
First the internal glow plug will be energized. Soon after, the starter will be powered up to have the rotor turning at
slow speed (3000- 5000 RPM).
Once the rotor is at correct speed, the fuel pump and solenoid valves will be energized. A few seconds later
(depending if the fuel is already at the engine or not) the fuel will ignite and the exhaust temperature will begin to
increase. The rpm and pump power will increase automatically. During this phase the display will display “IGNITION”.
When the ignition is detected, the display will change to “SwitchOver”, during this phase fuel is also routed to main
injectors and speed of the rotor will be progressively increased to about 8,000RPM.
Once this phase is finished, the RPM rises to 10,000RPM and the reading will be “FUEL RAMP”. In this phase the
ignition system is switched off.
The fuel flow and starter power will be increased automatically to increase the RPM quickly up to idle at 60,000RPM.
Before arriving to idle the ECU will automatically disconnect power to the starter. When the rotor speed reaches idle,
the screen will change to “Run IDLE” and the engine speed is adjusted to the idle RPM.
The engine is running!
Control of engine power/rpm is now handed back to the transmitter and controlled by the position of the throttle
stick. Initially Increase/decrease the throttle slowly, verifying that the engine accelerates/decelerates following the
throttle command. Take special care around the engine intake; keep your hands at a safe distance along with any
objects as they can be easily ingested.
Engine shut down procedure
To shut down the engine lower the trim and the stick. It is recommendable that before shutting down the engine to
restrain the model and then raise the throttle stick to approximately 25%, allowing temperatures to stabilize for
around 5 seconds before carrying out the shutdown procedure. After the shutdown the ECU will keep the starting
motor running to cool the engine under 100ºc. A special feature on this system is that the power of the receiver can be
switched off before the cooling procedure is complete. The ECU will shut down itself when the procedure is complete.
