This upgrade kit gives you the option to adjust your AEG for specific preference, while also providing Statistics which can be checked using the USB-Link and GATE Control Station App for PC, smartphones, and tablets. With this, you can check your weapons rate of fire, trigger response, modules temperature, motor current, battery voltage, and number of BBs fired. it enables you to adjust the trigger sensitivity between 250 possible settings ( sourse : TITAN GATE website ) to get the perfect feel and greatly improves overall realism. TITAN gives you the option to adjust the fire selector mode, burst mode, burst, ROF Stabilization, ROF Control, battery protection, low battery warning, 30-round limit, cycle detection, equalizer, active brake and more. The eight integrated sensors ensure you are given the most accurate and useful information available. This module is the first and only MOSFET that can get the newest firmware updates via the internet, which means your one time purchase will be regularly updated with upgrades. I think its the best MOSFET.
