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."
