Build your own recoil
Follow along in the video to learn how to build you own recoil modification. The electrical hook up is the same as a Tamiya recoil or a Heng Long recoil. Two wires feeding the motor with the negative being routed though a micro switch on the gun. The third wire is a trigger wire and bypasses the micro switch by being wired directly to the negative pole on the motor. This is fed from a negative trigger source. This could be the airsoft wire on an RX 18 ( Yellow wire), or the Benedini Trigger point
