RE: ESC Programming
OK, start with which model.
the ezrun 35amp ESC in the caldera can be programed with ease via a $10 program card(if it even costs that much)
the ezrun 80amp in the 8e's can be programed as well with a program card. closer to $20 for the card tho. i believe that rufaster.com and urchobby.com have them.
the novatech ESC in the epx pros does not need any programing. it auto detects end points, nimh and lipo packs ect.
those are the ESCs i know about. the others i have yet to use.
