New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Ultimate Performance is at Your Fingertips

The powerful Zion Arms Programmable ETU is here and ready to drop into your favorite Version 2 M4 style AEGs! This top of the line upgrade component offers incredible performance and customization without nuking your wallet from orbit!

The Zion Arms Nebula works by utilizing a magnet embedded in one of the gears. This gear is included in the package, and it synergizes with the ETU's sensors to give you ultimate control over your gearbox. By knowing exactly how many rotations the gear has made thanks to that magnet, this chip allows you to program your select-fire controls for things like burst fire, semi-only, or binary trigger options. Programming your mosfet is incredibly easy by following the instructions included in the box.

This ETU is easy to install in guns from brands like G&G, KWA, VFC, E&L, Lancer Tactical and Arcturus, while other brands may require professional installation or modification to the gearbox. It is designed to drop into most standard V2 gearboxes with minimal work. It's recommended to use an 11.1v 25c LiPo battery for the best performance. The Nebula will help increase trigger response and rate of fire, by maintaining the electrical current in your airsoft gun, to give you new levels of performance you wouldn't have otherwise.

Product Information:
Excellent MOSFET unit

simple and easy to program. very reliable and for the money it delivers. deans connectors pre installed are a plus. If you are still using Tamiya type connectors cut them and burn them all. move to deans

installing it in the gearbox is a bit of a hassle but all things considered, most jobs that require opening the gearbox are a hassle. watch for flying springs...LOL
