Perun ETU++ Airsoft MOSFET for G&G ETU Gearboxes

The Perun MOSFET upgrade kit is one of the smallest MOSFET devices on the market. There is a specialized, ultra-low resistance transistor used in Perun channels that power from the battery directly to motor, while the mechanical contacts only have to handle small amounts of current to turn the MOSFET on and off. Thus, this greatly extends the service life and lowers overall resistance resulting in a more dependable airsoft gun with higher rate of fire.   The following settings are possible to set any combination on the firing modes under "SEMI" and "AUTO" selector positions independently:SafeSemi-automatic2 to 5 round burstFull-automatic   Program all of the settings by using the memorable sequences of fire selector switching and trigger pulls. This is used for not only firing modes, but also switching active brake, precocking, and battery protection on / off. Altogether, this allows the user to change the settings at any moment in a matter of seconds, even under the pressure of e
