- Built-in Motor Control Unit
- Programmable fire modes
- For JACK™, F2™, F1™ & Fusion™ HPA engines
If you're running an older FCU and want to update, the PolarStar Fire Control Unit for HPA Engine; Rev 3.3 is a superb option. Compatible with the PolarStar JACK™, F1™, F2™, Fusion Engine™, this is the latest iteration of the PolarStar FCU.
This digital FCU can be programmed for various fire mode settings and tuning options, including burst modes, anti-stiction mode, rate of fire adjustment and semi-auto limiter, to name but a few. Programming is super easy thanks to the built-in LCD screen and joystick, allowing you to adjust on the fly in seconds, should the need arise. The tuning options available depend on the HPA engine that will be used; check the user manual for more information.
The FCU is pre-wired to a mini-JST connector and requires a battery to function. We recommend an ASG 7.4V 250mAh LiPo, although the size of the battery you choose depends on the available space on your donor platform.

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
