Part of the review do the Gate Electronics Titan V3 ETU for version 3 gearboxes by Antre du Dingo Dingchavez is showing you how to install it. Non-French speakers can follow the English subs... "Let's install the Titan V3 together! Don't worry, it's easy, just take your time. Thanks a lot to GATE and Airsoft Entrepot, without them I would probably not have done this video."
