Go for the losi combo, much better value plus sintered rotor, ive had the earlier automatic set up stuff from LRP and its terrible, i turned it on and the speedo got all confused with itself, then it went up in smoke and melted

got a free replacement and it did the same

thats personal experiences though not sure about the newer ones. have also had bad experiences with bonded rotors, so go for the losi set up! oh 10.5 turns should be plenty fast enough. Hope this helps
