fuel to the motor, raising it of power until the idle speed is reached. This final condition is signalized 
extinguishing the LED. The minimum power of the pump and the speed of acceleration in the start 
phase are programmable parameters by the user 

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. Aside from the circuits of visualization and control.

 

3. Installation of the FADEC

.

  

When being an electronic equipment, the installation of the FADEC in the model aircraft is similar to the 
one of the radio receiver. It has to be in an accessible site, with few vibrations and far from the heat of 
the engine.

  

3.1 Battery 

  

The battery that supply starter and pump can work with voltages of the battery from 6 V to 12 V. for 
each successful run of turbine need fully charge battery always. 

3.2 Receiver of radio

  

The FADEC is connected to the radio receiver like a standard servo in the channel of the throttle, 
receiving from this one the information of the throttle and the supply.

  

3.3 Thermocouple

  

The FADEC works with a thermocouple of type " K ", apt until 1100ºC. The provided standard 
thermocouple consists of a wire of Inconel of 1.5mm of diameter and 0.5m of length finished in a

  

connector who fits directly on the FADEC. The recommended installation consists of practicing a drill of 
1,5 mm in the exhaust nozzle of the engine and inserting the end of the thermocouple so that it be 
2mm within the flow of exhaust gases. In case that the motor have zones hotter than others in the 
exhaust (hot spots), the thermocouple must be installed in the medium temperature zone.

  

Because the sensible zone to the temperature is the end of the thermocouple, in any case cut the 
thermocouple, since it will be destroyed . Also, do not bend it with pliers or other utensils that cause 
very acute angles of curvature. The installation is due by hand and the different curves must have the 
greater radius possible. We have thermocouples of until 1m of length and cables to extend it.

  

In principle any type of thermocouple " k " can be installed, but it is necessary to consider the thermal 
inertia of it, since the temperature of the engine can raise much quickly that the one of the 
thermocouple and cause not controlled situations of overheating.

  

3.4 RPM sensor 

It’s a “Hall” type of sensor to count the rpm of the engine rotor the reading of the rpm will instructing 
ECU of maximum speed, idle speed, or stop engine. 

3.5 Fuel pump

  

It is necessary to watch that the pump does not have too much friction and the starting is smooth. 

3.6 Starter (full auto) 

Using the recommended starter motor by engine maker, if bigger voltages are used, then the high 
current from the motor can damage the ECU, if you feel ecu becomes warm, you should stop and 
check if anything wrong or wait for a while to give another try. 

3.7 Glow plug (full auto)
