Candle [PF2] FIRE POWER F2

Warmth: extra cold

• Candle recommended for high-speed aircraft engines with high nitromethane content

Definition of candle warmth:

If the engine is working properly on the A plug, and after replacing it with the B plug, the needle needs to be screwed in to achieve full - equal revolutions (the mixture is lean), it means that the A plug is warmer than the B plug. The B plug requires additional heat from combustion. lean mixture to obtain the optimum operating temperature.

Correct selection of the spark plug's heat allows you to increase the speed by up to 2000 rpm, the correct adjustment of the mixture composition, which guarantees high power and durability of the engine, and allows you to improve the so-called "transition" when changing revolutions. Too cold a candle causes a drop in power and a bad "transition". A spark plug that is too hot causes pre-ignition, engine heating and detonation combustion, which can damage the spark plug.

ATTENTION!!! The candle supply voltage should not be higher than 1.4V. Otherwise, the candle will be destroyed (burned). In the case of powering the candle from a battery with a higher voltage (e.g. 2V), an additional resistor or resistance wires should be used to lower the voltage.
