BTC Chimera Mk3
For ACR Gearbox

An external variant of the Spectre Mk2 with the added versatility of interchangeable trigger boards and wirings with no soldering required.

Highly configurable controller provides hundreds of possible select‑fire combinations. All three selector positions can also be individually programmed to have a different burst count, RoF, precocking, etc, for each position.

Utilizes dual IRL3034 MOSFETs and triple surge suppression diodes to handle the most demanding builds, and protected with low-voltage, overcurrent, and temperature monitoring.

Bluetooth‑enabled to provide quick and convenient adjustment of settings with your smartphone.

Advanced Technology
  • Fully computerized with dual hi-speed ARM & PIC microprocessors to support high fire rates.
  • Overcurrent, low-voltage, and temperature monitoring protects the controller and connected battery.
  • Massive TVS diodes suppress up to 9000W of inductive motor spikes which typically destroys other FETs.
  • Uses 16-AWG mPPE wires for thinner size and superior abrasion resistance compared to typical PVC wires.
  • Ultra-low battery drain during sleep mode preserves battery charge if left connected during storage.

Wireless Bluetooth Interface
  • Quickest and most convenient method of programming, requiring just a smartphone and the BTC app.
  • Reprogram AEGs on the field in seconds, no need for complex trigger inputs or attaching other devices.
  • Password lock and shortened signal range helps deter unauthorized access attempts to the controller.
  • No pairing necessary between the device and smartphone, can be accessed instantly from within the app.
  • Fully certified by the FCC (USA), IC (Canada), CE (Europe), and 日本電波法 (Japan).

Essential App for Tuning
  • App can serve as a "wireless multimeter" to display battery voltage, current draw, and FET temperature.
  • Displays timing of shot cycles and RoF to assist with fine-tuning AEGs to desired performance.
  • Records number of shots on each trigger pull and the total number of shots since battery connection.
  • Diagnostic functions display in real-time which sensors are engaged and a log of previous errors.

MOSFET Trigger
  • Solid-state motor switching eliminates the damaging electrical arcs associated with contact switches.
  • Lower resistance compared to the default contact switch, thereby increasing electrical efficiency.
  • Driven by a powerful N-MOSFET with a rating of 240A startup current and 1.7mΩ resistance.

Motor Active Braking
  • Reduces the motor spin-down time during cutoff to help minimize over-traveling of the piston.
  • Prevents double-firing issues that may occur due to excessive over-travel on high speed setups.
  • Smart thermal throttling helps control heat buildup during quick sustained bursts of fire.
  • Driven by a powerful N-MOSFET with a rating of 240A startup current and 1.7mΩ resistance.

LiPo / LiFePO4 Protection
  • Monitors LiPo and LiFePO4 batteries to cut off power when nearing the overdischarge threshold.
  • Simply set the number of cells and the controller will automatically use the proper cutoff voltage.

Programmable Digital Fuse
  • Current monitoring with overcurrent cutoff (self-resetting) renders physical fuses unnecessary.
  • Adjustable cutoff threshold from 20-60A to prevent the battery from exceeding its rated output.

Cycle Completion
  • Gearbox will always complete the current shot cycle regardless of when the trigger is released.
  • Keeps the piston properly reset to minimize gearbox stress and provide more consistent startup cycles.
  • Replaces the cutoff lever mechanism entirely, eliminating the biggest source of trigger jams in AEGs.

Full-Config Fire Select
  • All 3 selector positions can be individually configured to provide 700+ unique combinations.
  • 9 available fire modes for each selector position:
    • Safe
    • Semi fire
    • Auto fire
    • Burst fire (full)
    • Burst fire (interrupt)
    • Burst / auto hybrid (full)
    • Burst / auto hybrid (interrupt)
    • Semi / auto hybrid
    • Semi / auto ramping
  • Burst mode supports 2-10rnd bursts and can be individually configured for each selector position.
  • Burst (full) will continue firing remaining rounds regardless if the trigger is released early.
  • Burst (interrupt) will immediately cease firing remaining rounds if the trigger is released early.
  • Hybrid mode fires in burst (or semi) then transitions to full auto if the trigger remains held down.
  • Hybrid mode transition delay is adjustable, ranging from immediate up to a one second delay.
  • Ramping fires in semi and transitions to full auto on rapid trigger taps (5 taps/sec activation).

Hardwire Semi-Only Lock
  • Semi-only can be hardwired via a solder jumper on the board to provide a semi-permanent lock.
  • Conforms to laws or field rules that forbid AEGs with readily accessible means of bypassing semi-only.

Rate-of-Fire Control
  • All three selector positions can be individually configured for different fire rates.
  • Each cycle runs at full speed but adds a user-defined pause between shots to reduce RoF.
  • This delay-based method preserves the original feel and sound of the gearbox cycles.

Piston Precocking
  • All three selector positions can be individually configured for different precock timings.
  • Precocking stops the piston in a compressed state so the next shot can be fired more instantaneously.
  • Adjustable precock duration of 5-70ms to precisely control the holding position of the piston.
  • Improves trigger responsiveness for DMR and low RoF builds. Compatible with short-stroked pistons.

Sniper Trigger Delay
  • All three selector positions can be individually configured for different delay durations.
  • When firing ceases or the trigger is released, further trigger pulls are ignored for a short duration.
  • Adjustable duration up to 1 second to limit firing rate for gameplay scenarios or sniper builds.
  • Low durations (milliseconds) can help prevent accidental bump-firing when using a feather trigger.

Frequently Asked Questions


Is the Chimera intended to be front‑wired of rear‑wired?

The Chimera is designed to support any wiring direction so long as there is enough room for the controller itself. The included battery wires (40cm) and motor wires (30cm) can be trimmed to any length prior to insertion into the Chimera's wire terminals.


Why use mPPE insulated wires instead of PVC, silicone, or teflon?

Silicone PVC Teflon mPPE
 Durability LOW LOW HIGH MED
 Diameter LARGE MED SMALL SMALL
 Flexibility HIGH MED LOW MED

Durability: mPPE insulation provides greater abrasion resistance than PVC and silicone, and are therefore less likely to be accidentally torn during installation.

Diameter: mPPE wires are as thin as teflon wires, which allows the included 16‑AWG mPPE wires to fit in gearboxes designed for the lower capacity 18‑AWG PVC wires.

Flexibility: Teflon wires are extremely stiff which can be inconvenient when attaching or removing batteries, whereas mPPE wires retain the same flexibility of PVC wires and thus remain easy to work with.
