Wolverine Airsoft's Bluetooth FCU is compatible with both sister lines of Wolverine's SMP engines, the INFERNO and HYDRA. This FCU allows all the tweaking and tuning for Dwell, Rate of Fire, and Burst functionality via bluetooth all from a compatible Android phone. Additional features are also available via the companion App and Wolverine airsoft is constantly adding more. The app also features twin tournament locks for use in events and milsim. The lock features an uninterruptible timer as well as a game-master enabled cancellation password.
