LCT Airsoft got this short video showing their AEG gearboxes being equipped with electronic trigger units or ETUs which are becoming standard in AEGs these days. They show four leading makers of ETUs with one being AceTech from East Asia whilst the three, Gate Electronics, Perun Airsoft, and Airsoft Systems are based in Europe.

LCT Airsoft has announced their Evolution, AEGs with built-in E.T.U. systems. This system was developed in collaboration with leading MOSFET manufacturers in the airsoft market, including GATE Electronics, Perun Airsoft, Airsoft Systems, and AceTech. The new system offers a more stable and responsive field and gaming experience while also protecting your airsoft gun. For more information about this product, please visit the LCT official website.

4UAD Smart Airsoft's latest ASMR sessions covers the Arcturus AK-12 With Jefftron ETU & ADV brushless motor. The AK12 is taken apart to remove the gearbox. and gets fitted with the Jefftron ETU and follow the Jefftron Sticker Tips. Next, a test of the sensors and shim the gears before installing the piston and closing the box followed by the installation of the ADV Brushless Motor and pair the selector. From there, it's the assembly of the rail and barrel before conducting a final test and mag dump.

Time for another ASMR session with 4UAD Smart Airsoft as they put together an upgraded SIG 552 AEG from ICS Airsoft by equipping with a DV Brushless AEG  motor and adding a Jefftron ETU. As for the suppressor mounted, it is the RGW suppressor. Watch carefully the installation which includes a mag dump to check how it performs. Just try to stay awake as ASMRs usually lull us to sleep.

West Coast Airsoft Servis (WCAS) from Slovakia reviews Delta Armory ETU series if he can recommend this series to his viewers... "WCAS review of the Delta Armory ETU series, where I dissected the weapon in every detail and pointed out the things I like and don't like. Then a minor upgrade and tuning that every weapon needs."

L'antre Du Dingo tries the Eshooter Kestrel V2 ETU bluetooth if it is something that he wants installed on his AEGs. Made for the standard Tokyo Marui V2 Gearbox, it is feature packed with pre-cocking, adjustable trigger sensitivity, battery protection, active breaking, ROF control, and more. It comes with an app to do the setttings via bluetooth.

L'antre Du Dingo checks out the recently released ETU from Perun Airsoft designed for the Tokyo Marui P90.  It is also compatible with other Tokyo Marui P90 clones such as the ACMs, Asia Tactical, Classic Army, Cybergun, CYMA, J Tactical, and JG. It is incompatible with G&G and Krytac P90s perhaps due to their having their ETUs/MOSFETs.

Maydaysan Airsoft finds a feature of the eShooter Kestrel Airsoft ETU V2 MOSFET to be insane... "Is the Kestrel Airsoft ETU better than a GATE TITAN? Many Airsoft ETU's try to topple the king, but this one takes the cake with one particular ETU feature I enjoy."

Rock Bottom Airsoft gets to test the Eshooter Kestrel V2 Airsoft AEG ETU together with is accompanying app... "In this video we dive into the Eshooter Kestrel V2 again. This electronic optical trigger unit and MOSFET is Bluetooth controlled via an app and has a wealth of features.

Adzzzys Armoury shows how to install the Kestrel V2 Wireless ETU using sample sent to him... "Video for the installation and testing of one of the New Kestrel V2 Wireless Electronic Trigger units from Eshooter. Eshooter provided me with one of their new Kestrel V2's to install and test. I have used my Classic Army G3A3 for this video as I was experiencing problems with the standard mosfet, where the gearbox would just lock up and refuse to fire."
