Five optical trigger sensors allow you to control trigger sensitivity. You don't have to disassemble your AEG. Just connect to the GATE Control Station App to adjust the trigger to your preferences and skill level. 


Two selector sensors allow you to take advantage of hundreds of selector mode variations, depending on firmware edition. The following modes are available for selection*:

SAFE – prevents your gun from firing, even if the safety lever is removed

SEMI – allows you to fire one shot per one trigger pull

BINARY – allows for firing one shot on the trigger pull and another shot upon release 

BURST – enables you to shoot a predetermined number of BBs, which is very useful in MilSims and when using low-caps; there are 2 BURST Modes available: 

  • Full – a burst is shot in full, even if the trigger is released early
  • Interruptible – the burst can be interrupted by releasing the trigger early

BURST/AUTO – available in Full BURST Mode only; allows for extending a burst by any number of shots – if you hold the trigger after the burst is shot, it switches to AUTO Mode 

AUTO – shots are fired as long as the trigger is pulled

SEMI RAMPING – if you pull the trigger very fast, it switches to AUTO Mode

*You can check selector configuration possibilities provided by particular Firmware Editions here.

Please note: In the case of Regional Lock, only SEMI Mode is available. Check law restrictions in your country.


Victory in the game is often a matter of fractions of seconds. The new advanced cycle detection algorithm, thanks to a dual gear sensor, allows for smooth and precise pre-cocking adjustments in even the most exigent configurations increasing trigger response. Thanks to pre-cocking, you gain a trigger reaction similar to a real replica. This allows for initial spring compression, which speeds up trigger response significantly.

There are two Pre-Cocking Modes:

  1. AUTO Mode – the spring is automatically compressed after each shot—you choose the level of pre-cocking from the list (percentages or levels)
  2. MANUAL Mode – set the pre-cocking values yourself—instead of percentages there are time settings, you have to choose the time for yourself by trial and error

*Now Pre-Cocking is fully operational in SEMI, BURST, and AUTO Modes

Please note: using Pre-Cocking increases wear and tear on the gearbox.


Pre-Cocking is fully operational in SEMI, BURST, and AUTO modes and there's no need to set the Pre-Cocking boost manually; you can simply set Pre-Cocking as high, mid or low
Full Cycle—when Pre-Cocking is off, TITAN II Bluetooth® ensures that the gearbox completes a full cycle and you gain more reliability


This feature allows for simulating magazines of lower capacity than actually used. Depending on Firmware Edition, allows you to set a simulation of magazine capacity from 1 BB up to 250 BBs. Even if you have a high-capacity magazine, this function lets you truly increase the realism of your game by imitating that your magazine is real-cap. Then, after apredetermined number of BBs is shot, you will have to wait for a previously defined amount of time before the next shot can be fired as if you were really replacing an empty magazine with a full one. In the case of ADVANCED and EXPERT Firmware, you can also set Low Ammo Warning.


Enables the reduction of a gun's rate of fire. You can use stronger batteries and still have a ROF exactly as you like. Depending on firmware edition, you can choose between Adaptive, Manual PWM, Manual Delay, and Manual Delay + PWM

Adaptive – set your desired rate of fire; the brake and delay will be automatically adjusted to achieve this value.

Manual PWM – set braking power in percentages between shots

Manual Delay – set exact delay between shots in milliseconds

Manual Delay + PWM – set braking power and delay manually



We know how vital fast trigger response during combat is. That's why we've developed the Smart Trigger function, which enables you to achieve faster trigger response. It works with the ROF Control System. During the first shot, the microprocessor sets the ROF control to 100%. After the first shot, it switches to a previously programmed value (e.g. 50%). As a consequence, the first shot is fired at a full ROF and subsequent shots at a reduced ROF. The best results can be achieved when using a battery with above standard voltage. For example, if you’re using a 7.4 V battery, you can replace it with a 11.1 V one. This way, you will achieve faster trigger response with the same rate of fire than with a standard battery. 

*Works only if ROF is decreased using the power settings of ROF control.


Protection against battery over-discharge. Modern LiPo and LiFe batteries are very sensitive to over-discharge. If you do not want to damage the battery and you care about its service life, this protection is indispensable. The microprocessor is constantly monitoring battery voltage. When voltage drops to a critical level, it will not allow firing. The number of battery cells can be detected automatically.

When battery voltage drops to a predefined level, the motor will vibrate at regular intervals. The user is warned 5 times before the battery is discharged. Each warning is communicated by 3 vibrations: HIGH → MID → HIGH. 


Adjust the motor’s braking power according to your needs. Choose breaking value manually or set the Adaptive Active Brake. It will stop the piston in the front position, which eliminates unnecessary stresses, increasing the service life of the gearbox and its parts.

Adaptive Active Brake – Automatically adjusts the motor’s braking power according to the setup of your replica. Prolongs the lifespan of the motor and reduces the heat by adjusting the motor’s braking power.

Manual Active Brake – Choose your own value of active brake depending on your needs.


Thanks to the gear sensor, TITAN precisely detects where the cycle should finish. Therefore, even the shortest trigger action produces at least one full cycle. The optical sector gear sensor counts each tooth of the gear, so it's possible to use all types of gears: Infinite Torque-up, DSG, SSG, 19-tooth, and standard ones. In EXPERT Firmware, you can select the cycle manually.

Thanks to the cycle detection function you get:

  • Automatic BURST– there's no need to set the burst time. You can set the burst between 2 and 10 shots
  • Automatic Pre-Cocking– Pre-Cocking is fully operational in SEMI, BURST, and AUTO Modes and there's no need to set the Pre-Cocking boost manually; you can simply set Pre-Cocking as high, mid or low
  • Full Cycle– when Pre-Cocking is off, TITAN ensures that the gearbox completes a full cycle and you gain more reliability


This feature allows you to troubleshoot your AEG in case of any issue. Errors are communicated once they occur, and their description can be found in the GCS App.
GCS allows for making firmware updates via the internet, which enables you to quickly apply changes, improvements, and bugfixes. 


The Smart Fuse protects your AEG’s battery, motor, and controller, even in case of reverse battery connection. A combination of current, voltage, and temperature measurements makes your AEG installation highly reliable. It protects the MOSFET against overheating, overloading, and short-circuiting. If your airsoft gun gets jammed, this function protects the motor and battery against damage. 

    • Mind-blowing trigger sensor, with the advantages of the TITAN sensor but with the ability to set hair trigger with ludicrous precision: even 50 sensitivity levels for the first millimeter of trigger movement
    • Brand-new patented gear sensor detects each tooth and the direction of gear movement allowing for the world’s most precise cycle control
    • Mechanical protection of trigger sensors increase reliability—trigger sensors damage is now covered by warranty
