FCU Options

Have a Question?

When looking for electronics to power one of our airsoft engines in an AEG to HPA conversion, there are two main components: The trigger board and the FCU (Fire Control Unit). We offer two options: The Spartan Electronics board is a trigger board and FCU all-in-one design. While limited to only V2 gear boxes, the design enables the Spartan to take up less space and makes the system more cost effective and easier to set up. Our Gen 2 Premium FCU is a standalone FCU that connects to a separate trigger board. The Premium FCU allows for more options in fitment, tuning, and fire modes. Check out the information below to see which is right for your needs.

The Spartan Electronics board is a trigger board and FCU all-in-one. The key advantage of the Spartan Electronics board is it’s simple and robust design and lower price point. Settings are primarily manipulated with use of the trigger.
