6:TEST-DEVICES – Überprüfung der Systemkomponenten
The parameters printed in blue are important tests that should be done before the first
operation of the jet engine!
60:E-STARTER
Manual operation of the electric starter with the Up/Down keys
The starter motor should accelerate the turbine to 2000 rpm for at least 3 seconds.
Standard value: OFF
61:FUELPUMP
Manual operation of the fuel pump with the Up/Down keys
The STARTvalve and the FUELvalve remain closed for this test.
Standard value: OFF
62:FUELVALVE
Manual opening of the FUELvalve with the Up/Down keys
Check the valve with your finger to identify the correct one (two QS-4 connectors). Check the red
ring on the plug of the valve! It must be connected to the left jack at the JETRONIC (FUELvalve).
Standard value: CLOSED
63:STARTVALVE
Manual opening (pulsing) of the STARTfuel valve with the Up/Down keys
Check the valve with your finger to identify the correct one (one QS-4 and one QS-3 connector).
Standard value: CLOSED
64:DRAIN-FUEL
Use this function to pump the fuel back from the engine into the fuel cells. For this purpose, the fuel
pump is running backwards and both fuel valves are activated. This function is useful if you want to
store your model for a longer period or make modifications to it.
Standard value: OFF
65:ENGINE-RUN
Starting and testing the jet engine without the remote control
Activate the test run with the Up key (ON) and press the SET key to switch to the operating status
display:
The throttle/thrust display now shows -rel (release) and waits for your clearance with the Down
key: The fully automatic starting prodecure is activated.
Operation: You can stop the test run at any time with the SET key (like an emergency switch).
With the Up/Down keys, you can adjust the thrust between IDLE and 100 % (similar
to the R/C throttle).
CAUTION: Please keep in mind that a stationary test run of the jet engine can lead to
very high temperaures in the aircraft model (exhaust duct) due to the reduced airflow.
