hmmm well, i dun think it's the spring TOO bad, cuz i DID flip it over several times, as well as lose one and try a different one... so yeah, i think it's actually the drive axle..

BUT... after crazyglueing it a few months ago, the bit still isnt perfectly balanced. im almost certain it has to do with the weight distribution... the wires and all, as well as the motor and the gears are not going to give very even distrubution on either side
