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 replica 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 before the preset number of BBs has been shot
• Interruptible – the burst can be interrupted by releasing the trigger earlier - when the trigger is released, the shooting stops even if not all the BBs from the burst have been shot

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.

Enables you to set two different trigger sensitivities. Pulling the trigger slightly produces SEMI or BURST fire. Pulling it further produces BURST or AUTO fire. Select your sensitivity preferences for each stage.

Victory in the game is often a matter of fractions of seconds. Thanks to pre-cocking, you gain 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.

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 a predetermined 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. You can also set Low Ammo Warning.

Enables to set a predefined number of BBs fired in a single series. It can be used as protection against trigger jams. In case of emergency, you can stop the series by switching the selector position.

It lets you set the delay between shots or series to simulate the delay from reload or recoil. You can setthe delay to 0.2 s, 0.5 s, 1 s, 2 s or 3 s for ADVANCED firmware and 0.01-5 s for EXPERT firmware.

ROF Control enables the reduction of a replica’s rate of fire. You can use stronger batteries and still have the 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 the motor power throughout the duration of the shot

Manual Delay – set the 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.

LOW BATTERY WARNING
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 braking power of the engine to suit your needs. Choose the braking value manually or set the Adaptive Active Brake. It will stop the piston in the front position, which eliminates unnecessary stress, increasing the life of the gearbox and its parts.

Adaptive Active Brake – automatically adjusts the braking force of the engine depending on the configuration of the replica. Extends the life of the motor and reduces heat by adjusting the motor's braking force.

Manual Active Brake – choose your own active brake value according to your needs.

You don't need to fully release the trigger to fire the next shot. This option is really useful when the trigger sensitivity level is very high. Choose between two types of equalizer.

• OFF - to fire the next shot, you need to release the trigger until it reaches the selected trigger sensitivity level.
• 2LVL - to fire the next shot, just release the trigger until it moves over two adjoining sensors.
• 1LVL - to fire the next shot, just release the trigger until it moves over an adjoining sensor.

Thanks to the gear sensor, ASTER SE precisely detects where the cycle finishes. So, even the shortest trigger action produces at least one full cycle. The optical sector gear sensor counts each tooth of the gear, making it possible to use a broad range of gears: 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

You don't 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, ASTER SE 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.

Available in EXPERT firmware.

Do you want to achieve a higher ROF and faster trigger response? Are you planning a power upgrade of your gun? In this case, you need a MOSFET.

It targets the energy from the battery directly to the motor, bypassing the mechanical trigger contacts. As a result, you gain a higher ROF of the gun and faster trigger response.

This allows you to quickly check whether the drop-in module is working properly. It helps to locate where the problem lies when anything goes wrong.

Thanks to its special conformal coating, our product is resistant to atmospheric conditions (Military Specification MIL-V-173C).
