My granddaughter and I put this together, put in the batteries and switched it on…and nothing. Changed the batteries (just in case), checked All of the connections….and nothing. Tried another motor from one of the other kits. It ran for ten seconds…. then nothing. Did it again with another motor…ten seconds, then nothing. Seems all of the motors burn out quickly under any load (like wheels). I am surprised there were no other complaints about the poor quality of the motors. Maybe the company is sourcing them differently now.
