CAW M134 MOSFET Trigger

CAW Minigun has one BIG disadvantage - can shoots only for 5 seconds burts. Why? It's factory limitation. So let's make this minigun The Real Minigun.
My desing uses two standard mosfet transistors, which are able to gives over 400A of continuous current. YES! That's very high power.
You can connect a remote controled unit into the SW1 switch. It will eliminate second wire to original trigger.
