ive had it for afew weeks now superb bit of kit . bought two hpi plazma 5300mah lipos togo with it and have been driving back to the car still working on most occasions. both the motor and speedo get quite hot so i would recommend 10min breaks between batteries. after about 15/20 packs had been trough it the motor/speedo burnt out hpi replaced both, just send in the old ones replacements were with me in a couple of days no questions asked. great two year warranty that comes with it but why not have a reliable motor/ speedo in the first place?must be costing them a fortune! think im gonna upgrade next time it happens! not much else has broke on it bad driving not included=)
