Description of the FADEC.
Full auto
The FADEC (Full Auto Digital Engine Control) is a system of control for model gas turbine engine. Its
main function is to control the fuel pump, providing to the motor the necessary amount of fuel for its
operation considering the temperature of the exhaust gas, the position of the throttle stick and the rpm
of the rotor. Also it incorporates all of the protections necessary to guarantee that the engine stays
between its parameters of operation, arriving to stop the engine when detecting itself an important
anomaly. In order to make their assignment, the FADEC has a rpm sensor, a thermocouple input, a
servo type throttle input, a digital link to program and read the data, the connection of power towards
the fuel pump and the battery.
All of the measures that the FADEC makes can be read in a hand terminal, that is connected to the
FADEC by a special connector. The FADEC is totally programmable by the user to adapt the margins
of operation of each concrete motor. The configuration parameters are written in the FADEC by the
hand terminal. The programmable parameters by the user are:
Full power rpm
Idle rpm
Stop rpm
Maximum Temperature

  • Page 1 All of the measures that the FADEC makes can be read in a hand terminal, that is connected to the FADEC by a special connector. The FADEC is totally programmable by the user to adapt the margins of operation of each concrete motor.
  • Page 2 First, the FADEC verifies that the pulse of control of the transmitter is correct, that is to say, is between the limits fit by the user. If the impulse is not correct, or if impulses are not received during 0,5 seconds, the system assumes that there is a trouble with the radio and stop the engine.
  • Page 3 2. Hand data terminal . (HDT) The HDT is the tool specifically designed to program the FADEC, with a liquid crystal display of 16 characters by 2 rows and four buttons. The power supply is take from the FADEC, not being necessary batteries.
  • Page 4 4. Programming of the FADEC. The programming of the FADEC can be done from the terminal of hand or the PC. In any case the parameters to program are such and with such values.
  • Page 5 In case of doubt it is recommended to connect a servo to verify that the movement is correct from end to end and fast. Once the transmitter is OK, connect the FADEC and by means of the key " Menu Up " change to screen 2. With the trim and stick of the transmitter raised (Full power) the reading of "Pulse = xxxx"...
  • Page 6 (LED) that incorporates the FADEC. With the FADEC in start mode, that is to say, just started, locating the trim and the stick at lower side the LED must be off. When raising the trim slowly, the LED must ignite approximately to half of the throw of the trim.
  • Page 7 Habitually these values do not need adjustment and the recommended values are useful to most of the engines, but with the purpose of being able to use the FADEC with any type of turbine and pump combination they are included in the menu of adjustment of the user.
