SX2 Spur gear

[Rob_B]

Managed to go threw two spurs in two races, I havnt melted them just completly grinded the teeth off them. Could it be because its meshed to tightly? I have noticed that when you look down at the car the motor seems slightly offset to the spur so if one part of the pinion was meshed correctly the other side wouldnt be could this be a problem. Help needed thanks
