Default need advice: spur & pinion gears

Losi mini baja:

Sand got under the gear cover and chowed the plastic spur and pinion gears. Still functional, but will need replacing soon. Should I look for aluminum or steel ones to replace them, or will that just push the wear and tear onto the motor? Stock plastic parts are cheap, but I don't see why they won't just get chowed again soon as I go back into the sand. Need advice.

always stick with the plastic spur. it would probably be beter to go to a metal pinion, since a setscrew holds them down instead of a press fit, making them easier to change and more reliable. i believe the robinson pinions are the correct pitch, some please correct me if i am wrong. just be careful when setting the mesh on a metal pinion, the gear is definately not as forgiving as a plastic one would be.

Cool, thanks for the reply. I will replace them soon as I get some parts ordered. I wondered about running RCs in the sand. Seemed like sand would tear things up and it did. Its still fun to watch the mini-baja spit monster roosts though

Does anyone know the pitch they do use on the 1/18th scale vehicles. And who all makes these pinions w/ set screws?
