Advanced Technology

• Can handle power surges up to 9000 watts and even run on car batteries!
• Fully computerized and driven by a high speed PIC18F14K22 microprocessor.
• Multiple internal layers of heavy copper traces for greater current capacity.
• Short circuit detection and voltage spike suppression circuits to protect the controller.
• Smart thermal management allows the controller to remain cool under sustained firing.

MOSFET Trigger

• Eliminates damaging electrical arcing of the trigger switch contacts.
• Lower resistance compared to mechanical switching, increasing motor current.
• Driven by dual IRF671812PBF, a compact yet powerful next-gen MOSFET!

Dynamic Braking

• Eliminates the motor spin-down time to prevent the piston from over-traveling.
• Assists in keeping the piston properly reset to reduce stress on the gearbox.
• Prevents double firing on semi-fire in extremely high RoF setups.
• Also driven by dual IRF671812PBF MOSFETs!

Cycle Completion

• Gearbox always completes the last cycle regardless of when the trigger is released.
• Assists in keeping the piston properly reset to reduce stress on the gearbox.
• The motor will always have the smoothest and most consistent startup.
• Allows the anti-reversal latch to be removed.

Fully Configurable Fire Select

• Both selector positions can be individually configured.
• Available options for each selector position:
  
  • Semi fire
  • Auto fire
  • 2 round burst
  • 3 round burst
  • 4 round burst
  • 5 round burst
  • Semi with ramping
  • Burst-auto hybrid
  
  
• "Semi w/ Ramping" fires in semi and switches to full auto if the trigger is rapidly tapped.
• "Burst-auto hybrid" fires in burst and switches to full auto if the trigger remains held down.
• Can convert any AEG to semi-only by having both selector positions set to semi fire.

Adjustable Precocking

• Precocking stops the piston in a compressed state so the next shot is near-instantaneous.
• The precocking is fully adjustable and thus also compatible with short-stroked pistons.
• Offers improved realism and trigger response for sniper or low RoF builds.

Delay-based RoF Control

• Every cycle runs at full speed and pauses between each shot to reduce the RoF.
• More power efficient, less heat, more realistic, and better sounding than typical PWM-based RoF control.

LiPo / LiFePO₄ Monitoring

• Monitors LiPo and LiFePO₄ batteries to cutoff power before overdischarge occurs.
• Simply set the number of cells and the controller will use the proper cutoff voltage.

Programmable Digital Fuse

• Sensor-based current monitoring negates the need for a physical fuse.
• Cutoff threshold fully adjustable to help protect low-output batteries from over-current damage.

Gearbox Reliability

• Eliminates the trigger jam normally caused by the cutoff lever stopping at a certain position.
• The cutoff lever mechanism is no longer needed, greatly reducing the chances of semi-fire related issues.
• The anti-reversal latch can also be removed to make gearbox reassembly much easier.

Hopup Sensor Compatible

• Fully compatible with Airsoft System's hopup sensor unit to prevent firing when the mag is empty.
