No not at all .Actually other way around. I run metal 12T pinion with plastic 87 spur. I used to have a metal spur and it was noisy and wore quick. To me running metal on metal without any sort of lubrication just doesn't make much sence. With the plastic on metal it's quiet and the gears last way longer. By the way, Axial's come with a plastic spur and aluminum pinion from the factory.

Plastic spur is fine, the important thing is to set the mesh properly, as close as can be without binding. Use a magnifying glass, not a piece of paper!

Usually the metal pinion will wear out before the plastic spur. The plastic allows fine grit to be embedded making it like sandpaper, which abrades the metal pinion. Also each tooth on the pinion gear sees a lot more contact than the teeth on the spur. End result - pinions wear out first.

I use steel pinions on mine, wear much better than aluminium.

Cheers.
