Give your AEG an upgrade with the Fire Control MOSFET Unit. This device delivers power directly to the motor, with the trigger only acting as a switch. Not only does this lower the resistance and the overall performance of the motor, a MOSFET will also prevent the premature wearing away of trigger contacts. MOSFETs are recommended for AEGs running on high-voltage LiPo batteries. This device includes a programmable burst function and is compatible with 7.2 - 11.1V airsoft batteries that have mini Tamiya style plugs.
