anyone know of a aluminum spur gear i can throw in my x-cellerator? tired of shredding and replacing the plastic ones.

i wouldnt go with an aluminum one. you just need to set the mesh between the clutch bell and spur gear right and you should be fine. if you get an aluminum one youll probably break some other part of the transmision since you will have way more rotating mass with aluminum.

a good way to set the mesh is to loosen the engine, stick a folded strip of paper between the spur and clutch bell, move the engine so the paper is tight between the gears, tighten the engine down, and take the paper out.

thanks ill try that

Make sure your slipper clutch is adjusted properly as well.
With the body off, hold both back tires and try to spin the spur gear with your thumb. While you are pushing on the spur it helps if you roll the tires backward a bit at the same time.
You should be able to slip the spur gear when you apply a moderate amount of force.
This allows it to slip a little bit when you come down from jumps and bumps when the rears are spinning wide open and then come back into contact with traction.
