aster v3 3

Optical sensors

ASTER V3 is equipped with well-known and tested optical trigger sensor, the same as in TITAN V3, optical sensors detecting gear cam and selector positions. With the GCS App, you can easily calibrate, test and adjust all sensors.

 

Selector switching point adjustment

The selector sensor gives you an option for fine calibration of selector switching point.

Trigger sensitivity adjustment

The trigger sensor offers you even 315 possible sensitivity settings. You do not have to disassemble your replica. Just use GCS App to adjust the trigger to your preferences and level of skills. You can even activate 2-stage trigger and set two different trigger sensitivities. Pulling the trigger slightly produces Semi or Burst fire and pulling the trigger further produces Burst, Burst / Auto or Auto fire. Additionally, by upgrading firmware to ADVANCED or EXPERT version, you can even use equalizer mode. Thanks to this option, 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. The gen. 2 proximity trigger sensor offers the following sensitivity ranges, depending on trigger construction:

 

In total: 103–315 levels

 

In the first millimeter of trigger movement: 1–38 levels

Please note:

  • Trigger sensitivity and selector switching point cannot be set while programming via trigger.
  • USB-Link and Blu-Link are not included in basic ASTER sets
  • To upgrade your ETU, please go to our store and choose between ADVANCED (for 34,9 €) or EXPERT (49,9 €) firmware.

 

Features

ASTER gives you the option to adjust:

fire selector modes

FIRE SELECTOR MODES (gen. 2)

Two selector sensors allow you to take advantage of up to 343 fire selector modes variations, depending on the device firmware edition. The following modes are avaialble for selection*:

Safe – it prevents your gun from firing, even if 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 pre-determined number of BBs, which is very useful in MILSIMs and when using low-caps. There are 2 Burst modes available: 

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

Burst / Auto – available for Full burst mode only; it 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 fire selector configuration possibilites provided by particular firmware editions here.

Please note: In case of Regional lock, only Semi mode is available. Check the law in your country.

 pre cocking

PRE-COCKING (gen. 1.5)

Victory in the game is often a matter of fractions of seconds. Thanks to Pre-cocking, you gain trigger reaction similar to a real gun. It allows for initial spring compression, which significantly speeds up the trigger response. The spring is automatically compressed after each shot. 

Manual mode – it allows you to set pre-cocking boost time between 1–250 ms with 1 ms precision and provides automatic voltage drop compensation. Pre-cocking is fully operational regardless of fire selector mode.

Please note: Using Pre-cocking increases wear and tear on the gearbox.

magazine

MAGAZINE

This feature allows for simulating magazines of lower capacity than actually used. Even if you have a high capacity magazine, this function lets you truly increase realism of your game by imitating that your magazine is real-cap. Then, after pre-determined number of BBs is shot, you will have to wait for previously defined amount of time before a next shot can be fired, as if you were really replacing empty magazine with a full one. In case of ADVANCED and EXPERT firmware, you can also set Low ammo warning

series safety limit

SERIES SAFETY LIMIT

An AEG can continuously fire a predefined number of BBs in a single series. This can be used as protection against trigger jam. Important notice: In case of an emergency, you can always stop firing by switching the fire selector position.

sniper delay

SNIPER DELAY

It lets you set delay between shots or series to simulate the delay from reload or recoil. You can set 0.2 s0.5 s,1 s,2 s or 3 s delay for ADVANCED firmware and 0.01–5 s for EXPERT firmware.

rof control

ROF CONTROL

ROF control enables 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, Manual Delay + PWM.

Adaptive - set your desired rate of fire. 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.

smart trigger

SMART TRIGGER

We know how vital the fast trigger response is during combat. This is why we have developed the Smart Trigger function. It 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 voltage higher than standard. For example, if you use a 7.4 V battery, you can replace it with 11.1 V. In 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 by using Power settings of ROF control.

battery protection

BATTERY PROTECTION (gen. 2)

Protection against over-discharge of the battery. 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 monitors the battery voltage constantly. When the voltage drops down to a critical level, it will not allow firing. The number of battery cells can be detected automatically.

low battery warning

LOW BATTERY WARNING

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

adaptive active brake

ACTIVE BRAKE

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.

equalizer

EQUALIZER

It enables a dynamic trigger point, which allows you to shoot even faster. Available in ADVANCED and EXPERT firmware editions.

Off – to fire a next shot, you need to release the trigger until it reaches the selected trigger sensitivity level

• 2LVL – to fire a next shot, it is enough to release the trigger by ~40% of trigger movement
• 1LVL – to fire a next shot, it is enough to release the trigger by ~20% of trigger movement

cycle detetion

CYCLE DETECTION (gen. 1.5)

Thanks to the gear cam sensor, drop-in unit precisely detects in which position the cycle should finish. Therefore, even the shortest trigger action produces at least one full cycle. The sensor detects the gear cam instead of teeth, so it is possible to use all types of gears: Infinite Torque-up, DSG, SSG, 19-tooth and standard. 

Thanks to the cycle detection function you get:

  • Automatic Burst – there is no need to manually set the burst time. You can simply set the number of rounds shot in a burst (available options depend on the firmware edition).
  • Full cycle – when pre-cocking is off, the drop-in unit ensures that the gearbox completes a full cycle. This way you gain higher reliability.
   
notifications settings

NOTIFICATIONS SETTINGS

You can enable or disable information and warning vibrations, and make your gun stealth.

user profiles

PROFILES OF SETTINGS

Allows to access and switch between 3 different profiles customized for different preferences on the battlefield. Available in EXPERT firmware.

firmware update

FIRMWARE UPDATE

GCS allows for making firmware updates via the internet, which enables you to quickly apply changes, improvements and bug fixes. 

smart fuse

SMART FUSE (gen. 2)

Smart fuse protects your AEG’s battery, motor and the 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 becomes jammed, this function protects the motor and battery against damage. To reset the fuse, you just need to release the trigger.

mosfet

MOSFET

Do you want to achieve a higher ROF and faster trigger response? Are you planning a power upgrade of your gun? In that 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 a faster trigger response.
