Good choice on the HST pro. it's a great truck, but on the heavy side. With a 6s lipo mine weighs in at 12lb 5oz. It is extremely durable, only thing I've broken is a front body mount. IMO get the 10s lutach esc or the mmm. It's not worth the extra size of the esc unless you're going HV. If you do go HV, pick up some RCM 2500 5s packs and run them in series for 10s 2500mah, and get a neu 1515 2y.
