More info

Polarstar Gearbox type for Airsoft replicas.

Electropneumatic system in the design of a gearbox.

Fusion Engine is the pneumatic system that has revolutionized HPA in airsoft.

It works with compressed air (similar to paintball), with an air bottle of 200 or 300Bar (3000psi ~ 4500psi).

This system completely replaces your geabox and also removes the motor.

The Fusion Engine system is regulated by an electronic card (FCU) which is often placed in the stock tube and which will be powered by a 7.4V Lipo battery.

This mini electronic system allows you to adjust a whole bunch of settings like the following:

  1. Selection of the firing mode (full auto - burst going from 2 to 9 balls - Semi only)
  2. retention of the nozzle in the rear position (allowing it to let the bb's pass depending on whether your magazine goes up quickly or not the bb's): Can reduce the rate of fire.
  3. Adjusting the nozzle time in the front position (chambered bb's before returning to the rear position): May reduce the rate of fire.
  4. Air valve opening time adjustment (Adjusts the air pressure delivered): This changes on your FPS and the consumption of your bottle.
  5. Adjustment of the nozzle position before each shot (closed or open mode).
  6. Adjustment of the rate of fire; also called ROF in addition to other adjustments, it will be possible for you to climb beyond 35 seconds bb's.
  7. Adjustment of the delay between each shot (sniper mode) between each press of the trigger.
  8. Integration of a low battery warning according to the battery voltage.

The Fusion Engine system works with a pressure ranging from 80 to 120psi, this requires a second regulator on your bottle, the first regulator is called (PRESET), this first offers a pressure ranging from 200 to 1000psi.

On the second regulator you will come to place your air line called (MAMBA) to supply your replica.
