Wrench library

The know-how behind the diagnoses. Short, no-fluff guides for the jobs every basher hits sooner or later.

Heads upThese guides cover general principles that apply to most hobby-grade electric RC cars. Specific figures, like diff oil weights and gearing, are starting points from the wider hobby, not fixed values for every car, and some steps only apply if your car has that feature (oil-filled diffs, a steering damper, a tunable pinion). Always check your own model's manual for exact specs.

Gearing & speed

Before you fit a bigger pinion, check what it does to your top speed and heat. Drag the slider — the gauge sweeps from safe into meltdown in real time.
