Description G&G ETU Electronic Trigger and Mosfet Unit (V3). Specifically the selector is made for the AK series of airsoft guns. This is not a drop-in for G36 gearboxes. This is a replacement part for your G&G gun. This is for Version 3 guns. Two options: Front (short wires) or rear wiring (rear version has longer wires). We cannot guarantee compatibility with other brands. G&Gs new ETU includes technology that will automatically stop the gun from operating if it detects the battery voltage is too low. Once you disconnect the battery it will likely still operate in guns without this technology, as those products will allow the battery to drain completely flat. This means when using a G&G gun with ETU, your battery must be fully charged or the automatic cut off feature will kick in. This feature is designed to protect your battery as well as the advanced control board inside. To avoid disappointment ensure your batteries are discharged and freshly charged before use. This is known as ‘cycling’ your batteries. This technique also improves battery performance by promoting battery life and memory. * This product requires a 9.6v battery to operate. Lower voltage batteries will not be recognised by the ETU. Note: This is for Version 3 AK gearboxes with either front or rear wiring. If you need one for a M4 style, use the V2 ETU unit.
