  • ASTER SX for V2

    ASTER SX for V2 gearboxes – the natural successor of ASTER SE – merges years of experience with cutting edge tech. ASTER SX is fully compatible with popular brushless motors – even with batteries up to 11.1 V. The unit heats up less even while accommodating higher loads. ASTER can operate with stronger springs and more demanding configurations. ASTER SX comes with a free Quantum Trigger, so you can easily set sensitivity from ludicrous touch through hair to full movement. Improved programming via trigger gives you settings such as automatic Pre-Cocking, trigger sensitivity adjustment, Active Brake settings with top-class adaptive mode. Calibration available just via trigger and selector movement. ASTER V2 SX turns your AEG into future-proof advanced training equipment. All this, along with a thicker and sturdier PCB – 1 mm in thickness – makes ASTER V2 SX one of the most durable ETUs on the market. 

What distinguishes ASTER V2 SX from the competition?

  • ASTER SX is future-proof, thanks to compatibility with USB-Link and Blu-Link. You can update your firmware and get new options, connect additional accessories, check telemetry.

    ‎

    What is an ETU? It is an Electronic Trigger Unit replacing trigger contacts and the cut-off lever, which takes control of your AEG.

    Why ASTER's programming via trigger is user-friendly?

    ‎

    • you do not need to rush
    • you can navigate the menu very quickly and efficiently or slowly and calmly
    • the colors of the led lights are only a help – you can rely on the vibration of the motor
    • in case of any problems, you can use the very popular USB-Link or Blu-Link and use the GCS App

    ‎

    What is the self-learning automatic pre-cocking?

    ‎

    • thanks to Pre-cocking, you gain trigger reaction similar to real life
    • it will automatically set piston position
    • it is easy-to-use, just set one of the 3 modes: LOW, MID or HIGH
    • it automatically adapts to the battery voltage and rate of fire
    • ASTER gives you great flexibility and is future-proof. Today you can program the most important functions with the trigger, and tomorrow you can borrow a USB-Link or Blu-Link from a friend to configure advanced functions, perform a firmware update, run diagnostics or use the GCS app on a smartwatch
    • Hair-trigger – up to 60 sensitivity in the first millimeter of trigger movement
    • Top-notch automatic pre-cocking
    • Foregoing reverse polarity protection in exchange for unparalleled performance
    • You can update its firmware via the Internet
    • ASTER is a part of the GATE Ecosystem
    • Lowest in the market current consumption. Deep sleep mode with only 0.29 mA current consumption prevents battery discharge
    • Built-in voltage boost converter allows for trouble-free operation with weaker batteries and increases the switching efficiency
    • 3.75 V ready – it operates at very low voltage (even 1.2 V during the shot), which is important in high-tuned AEGs, where the voltage under load drops significantly
    • Sensor that supports Infinite Torque-up, DSG, SSG, 19-tooth and standard gears
    • The possibility of using a mechanical trigger lock
    • Compatibility with brushless motors

Does what I needed it to do
Size: 50mm/2inch, Color: Black, Number of Items: 4
Worked perfectly for routing all my wires for my desk. The included tie straps were an added bonus. Now everything is nice, tidy and secured to the back side of my rolling desk.

Great to clean up the cable clutter
Size: 50mm/2inch, Color: Black, Number of Items: 4
I finally got around to cleaning up the cable disaster on my home office desk and these grommets were exactly what I needed. They fit perfectly into the 2-inch holes I drilled, and the plastic feels surprisingly sturdy, not like that cheap, brittle stuff that snaps the moment you try to pop the cover back on. The little brush-like opening is a nice touch because it keeps the cords from sliding back down when they aren't plugged in, and the black finish looks really clean against my wood tabletop. For a 4-pack, the price was a total steal, and it honestly makes the whole setup look way more professional than just having raw holes in the desk. If humans are looking for a quick and cheap way to hide cord clutter, these are a solid bet.
