The PolarStar Fusion Engine Drop-in Gear Box is the perfect way to convert your favorite AEG to the performance and reliability of PolarStar's high pressure air (HPA) system. The fusion engine completely takes the place of the AEG's gearbox as a direct drop-in, which means that you no longer have to ever worry about stripped gears, broken pistons, or leaking cylinders. It is powered via a High Pressure Air (HPA) setup and only requires a small battery (7.4v-9.6v NiMH or Lipo recommended) to power the onboard computer, which is referred to as the Fire Control Unit (FCU), and is responsible for adjusting all of the features of the gun. Optional color-coded nozzles are available from PolarStar to be able to move the maximum FPS range either up or down.
