The NanoSSR is the highest quality basic MOSFET with Deans-t connectors. It is resistant to bad weather conditions. The use of new technology has allowed us for the maximum miniaturization. The NanoSSR is compatible with all the replicas, also the tuned ones. It works with any battery from 7.2V to 12.8V. MOSFET Do you want to achieve a higher rate of fire and faster trigger response? Are you planning a power upgrade of your rifle? In that case, you need a MOSFET. It targets the energy from the battery directly to the motor, bypassing the mechanical trigger contacts. As a result, you will gain higher rate of fire of the rifle and a faster trigger response, and the contacts will be protected against burn out.
