Yep same problem everyone else has had. I would have had less gear noise if I made one out of wittlin a wooden gear. Imediatly changed to slotit gears, runs better , had alot of loose parts also, trued the tires and did a mag mod. They better up their quality control or they will not get anymore of my money. Like the saying goes beauty is only skin deep and thats about as far as it goes with this piece.
