I've been looking and there is so many out there i dont know where to begin. i will be starting a .21-.28 engine in my truck. i heard that the 12v motor is the best but not sure. what is the 550 750 770 motors about. also i will probably be getting the losi 8ight buggy soon so i want a box that will be compatible that also. i know for sure i will have 12v battery in it. i was thinking about ofna 10253
