Airsoft MOSFET is an electrical system that reduces the resistance that arises in a system which causes a current to flow between the battery and the motor. With the use of a MOSFET you can effectively increase the functionality of the replica and improve its performance. What is, how to do it and how does the MOSFET work? If you decide to use the MOSFET control system, the current that drives the motor will flow directly from the battery and bypass the contacts. They in turn will only be responsible for opening and closing the current flow. This ensures that the contacts do not wear out and the ROF of the replica increases. The MOSFET with the wiring is ready to go and you have to do is solder it, which requires no special skills.
