ASTER V2 is a younger brother of well-known TITAN V2. This world's first 4th generation AEG Control System is destined for V2 gearboxes (including stock, low- and mid-tuned) and even for high-tuned guns (in case of EXPERT firmware). It was designed to achieve maximum reliability at attractive price and hence it has extremely profitable price-performance ratio. Transform your AEG by replacing trigger contacts with computerized controller equipped with innovative optical sensors. Gain a unique tactical advantage thanks to the extremely fast trigger response and lots of other useful functions. ASTER's smart fuse protects your AEGs battery, motor and the controller, even in case of reverse battery connection. This feature, along with the optical sensors, makes ASTER the most durable drop-in unit on the market. You choose how to configure ASTER - simply via trigger or through USB-Link / Blu-Link* and our advanced GCS app. To enjoy full potential of ASTER, you can upgrade its firmware to ADVANCED or EXPERT.

Disclaimer: Manufacture of this product requires all owners of this MOSFET Module to update your firmware to the latest version upon receiving the product and periodically. Failure to do so can result product mal-function and injuries. Usage of radios with excessive power output beyond EU / USA legal limits can cause the rifle to fire when it is not on safety. If you do not have the USB link you may purchase here:

"I have installed about 15 of these Gate Aster Mosfet without any issues.

It's a very easy installation. Here are the key features that I like most of about it.

1. I can retain the Safety Selector Switch
2. It's the same type of installation as the Gate Titan without the top Trigger board. (Dremel work on gearbox is not necessary)
3. I can do a hair trigger mod in many variation.
4. It works on SSG at 30 RPS and DSG at up to 50 RPS that I have built.
5. For the price point, I still have the ability of the GCS App on my Android phone & PC
6. Super long length wires for easy customization and soldering
7. Motor Connectors are pretty decent

"Melted down a trigger in my AEG, ordered the Aster because the Titan was completely out of stock everywhere due to COVID. Read all the reviews took the plunge anyway.

1. Easy enough to install. Need to do some tinkering to get all the stickers perfectly lined up.
2. As written in other reviews, you really need to buy the USB link to really get it tuned in. I had the basic and was able to make it work, but the USB link brought it to life.
3. Gate has updated there software. Really easy to use.
4. The old firmware has some bugs still. Again order the USB link, you wont regret it.

Would I purchase it again??? Yes I would. For the price, even with the USB link, this trigger is great.

I did learn also, that if you down load the new software (for free) and pruchase the upgrade to either advanced or expert, Gate discounts the upgrade.

"Easy installation, works great. I also purchased the link. Highly recommend. I dont care for the extra cost to purchase the upgrades.
