This spare part is an RC-scale spur gear cover made to fit Auper D6 kit owners who need a direct-fit replacement or a cosmetic refresh. The cover shields the spur gear from dirt and provides an accessible opening for checking the gearbox and performing small adjustments.
Fitting is straightforward: remove the original cover screws, swap in the replacement, and tighten at the existing mounting points. Verify screw torque to avoid stripping older plastic threads and recheck gear mesh before running the model.
As a tuning aid this piece is focused on maintenance rather than power changes. It keeps contaminants away from the spur assembly and speeds common tasks like checking spur/pinion engagement or inspecting gearbox bearings.
