The NF-Jet3 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 NF-Jet3 units are optimized to work with LEDs circles with a diameter of 105 mm and has 72 LEDs. The unit has two concentric circles. both circles can work from 7 to 12 V (10 to 12 is optimum). The modules has an over-current protection. The NF-Jet3 has a current limitation at 200 mA. Pretection circuits needs approx. 2V reverse, so the optimal conditions for unit are from 12 to 14 V (10xMiNH or 3xLiPo).
It implements Yellow-Sunny White-White colors.
