V3 Electronic Trigger Unit (ETU) for RK74 Elite E.T.U.
The V3 Electronic Trigger Unit is a drop-in upgrade for the RK74 Elite E.T.U. gearbox, engineered to deliver lightning-fast response, improved firing consistency, and programmable control modes. CNC-machined from aerospace-grade aluminum, the V3 ETU houses high-precision electronics that monitor trigger pull and cycle timing with microsecond accuracy. This ensures virtually zero trigger lag, remarkably crisp shot release, and a significant boost in rate-of-fire stability across single, burst, and full-auto modes.
Installation is straightforward: remove the stock switch assembly, slide the V3 module into the gearbox shell, and reconnect power leads. The on-board microcontroller supports multiple firing profiles—semi-auto with optional burst, full-auto cutoff after 1–3 rounds, and safe/semi/full configurations—selectable via a minimalist programming interface. Integrated MOSFET circuitry handles up to 30 A of continuous current while protecting your battery and wiring from voltage drop, ensuring each shot fires at peak voltage for consistent FPS performance.
Upgrade your RK74 Elite with the V3 ETU to experience unprecedented control, speed, and reliability in every engagement.
