The NF-Jet4 module serves to simulate flame on the output of the jet engine unsing red and yellow ulttra bright LEDs (Light-Emitting Diodes) 3 or 5 mm. The input of te module has to be connected in paralell with the engine controller. The intensity of the flame follows the power of engine. First color starts to light in the beginning of "gas" range. The second color starts on the middle fo the range. To increase the reality of the flame the light intensity chages in pseudo-rabndom period. The frequence of changes speeds up when increasing the engine power.

The module is connected to receiver by Graupner, Hitec type connector. The module can also be connected as an uncontrolled unit when disconnecting the cable to a receiver. In this case the light intensity is 100% (full gas).

The module has two outputs for light rings. Each output drives two colors. Usually the first color is red and the second one is yellow. The wires use the same colors system. The brown wire in the middle is ground. This is a common negative pole of LEDs (cathodes) for both colors. The system was designed to work with BEC recivers. Maximum voltaje is 6,0V.

The NF-Jet2 units are optimized to work with LEDs circuites; they both have a lenght of 258 mm and has 30 yellow LEDs.
The maximun consumption is 1,7 mA
