my 2 cents what about the h/l system by far the cheapes many of use that dont go to danville all the time dont see the reson to spend big buck one a i/r system that we might use once a year how ever if we do go some place like that we cant PLAY WITH THE BIG BOYS.as long as the tank can take and recive hits well run what you brung.i just cant see spending as much as a new tank on a control board. the h/l works just fine for us in the back yard.. may be the maco unite will work ? and oooo 9sec for a reload youve got to be kidding you could reload a 16 in. navel gun that fast or dam close.
