XRAY RX8 17T Pinion Replacement for Tuning - Arrowmax AM-RX8-348517  [AM-RX8-348517]

17T motor pinion for XRAY RX8 setups

The Arrowmax AM-RX8-348517 17T pinion gear is supplied as a motor pinion compatible with the XRAY RX8 chassis, machined from 7075 aluminium and treated with a hard coating to help reduce wear under standard on-road conditions.

As a 17-tooth option within a broader series, this pinion allows simple gear ratio adjustments; pairing different pinion tooth counts with the spur gear changes the drivetrain ratio and shifts the trade-off between acceleration and top speed. The lineup includes multiple tooth counts so model builders can experiment with gearing without altering other parts.

Practical notes: confirm correct mesh to the RX8 spur gear, set backlash to standard on-road settings, check alignment after initial runs, and replace the pinion if you notice visible tooth wear. The hard-coated 7075 material seeks to offer a compromise between light weight and enhanced wear resistance for routine motor gearing duties.
