BTC Spectre FET for V2 Gearboxes (Mk.II)

  • £120.00

3 Year Limited Warranty

A compact version of the Chimera Mk.II FET and utilizes FOUR powerful next-gen MOSFETs. Includes ALL the features the Chimera and fits completely inside the gearbox, making it ideal for AEGs with no room for an external FET. No soldering required.

The Spectre Mk.II is the most advanced FET yet with double the features of its predecessor including nearly every feature requested by the airsoft community. And for the first time in non-proprietary V2 gearboxes - Bluetooth!

New additions in the Spectre Mk.II:

Innovative Bluetooth interface with Android & iPhone devices
- Quickest and most versatile method of programming AEGs. No more complex trigger inputs or accessing the battery compartment.
- Program your AEG mid-skirmish in literally seconds with no need to bring additional tools or the manual, just a smartphone.
- User-programmable passcode and a shortened signal range prevents any unauthorized setting changes.
- No need to "pre-connect" to the Spectre in the smartphone's settings. Is 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 utilities for both users AND professional techs
- Smartphone app reports battery voltage, current draw, and FET temperature. Turn smartphones into a "wireless multimeter" for your AEG.
- Reports timing of shot cycles and RoF to assist technicians in fine-tuning AEGs (eg: motor height) to achieve the best possible cycle rate.
- Diagnostic functions that display which microswitches are pressed in real-time and also what error (low volt, fuse tripped, etc) has occurred.
- Records total number of shots fired since the battery was connected and also for each trigger pull.

Triple fire-mode selector - SAFE fully programmable
- Similar to the previous Spectre each selector positions can be programmed individually, allowing more than just SEMI-BURST-AUTO.
- Maximum programming flexibility where all three selector positions can have its own fire mode, RoF, precocking, and more.

Largest selection of fire modes for each selector
- Safe
- Semi
- Auto
- Burst [non-interruptible]
- Burst [interruptible] NEW
- Burst/Auto hybrid [burst non-interruptible]
- Burst/Auto hybrid [burst interruptible] NEW
- Semi/Auto hybrid NEW
- Semi/Auto ramping

Both non-interruptable and interruptable burst fire
- Non-interruptable completes a burst even if the trigger is released, whereas interruptable stops mid-burst upon trigger release.
- Until now FETs had only offered one or the other but now you can have both. Also applies to the burst portion of burst/auto hybrid.

Programmable transition delay of all hybrid fire modes
- You can now adjust how long the trigger needs to be held before hybrid mode transitions into full auto.
- Until now FETs only offered fixed delays that did not suit everyone but now you can choose between zero delay or up to 1s delay.

Programmable firing/trigger interval
- Ignores trigger inputs for up to 1s (adjustable) after a semi or burst fire. Helps restrict rapid firing in specialized builds.
- Lower intervals can also help prevent accidental "bump firing" on semi when using a feather trigger.

Hardware-level semi-only lock for regional laws
- Can only be enabled/disabled by using a soldering iron to remove/bridge a solder jumper.
- Conforms to semi-only laws that forbid AEGs with readily accessible means of bypassing semi-only.

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.

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.

Hopup Sensor Compatible

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