BTC Chimera MK.II for PTS Masada ACR

  • £155.00

The BlackTalon Concepts Chimera is a highly advanced user programmable compterized AEG MOSFET. Designed to provide highly advanced electronic fire control, extreme power handling and simple, drop-in installation.

It consists of two units: The main MOSFET computer board, and a trigger board. The main board contains most of the electronics; powerful solid-state switches, microprocessor, protection components etc. The trigger board contains the trigger switch, cut-off lever sensor and fire selector sensor, and replaces most of the stock trigger assembly.

This two-board arrangement brings many advantages over other drop-in MOSFETs because the main board can be bigger and therefore contain larger, more powerful components, increasing power handling and reliability. The trigger board now needs far fewer components, so the switches can be placed in the perfect positions without having to fit around other parts. It also means that the Chimera can be made compatible with many different guns by only changing the trigger board design; expect to see versions of the Chimera for guns other than just the V2 and V3.

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 a IRLS3034-7PPBF, the world's most powerful D2PAK-style 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 the powerful IRLS3034-7PPBF MOSFET!

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 (under certain circumstances) to make gearbox reassembly much easier.
