Spur Gear Mesh

If you run your RTR vehicle and notice the motor feeling overly hot, or the car sounds like the gears are whining, it may possibly be your motor pinion and spur gear mesh is too tight. To adjust this, you should first remove the spur gear cover so you can access the gears. There should be a small screw holding the motor into place and a small pivot channel. Loosen that screw until the motor pivots freely. Pivot the motor until the pinion fully contacts the spur gear.
