Hello, I have a Traxxas XMaxx, I keep stripping the pinion gear. I am using a 15 tooth gear at the moment, I am wondering if a gear with more or less teeth would be more robust, can you give me any info you might have re this please? Thanks, Pete

The x maxx uses mod 1 gearing so this will not work , if you look under the x maxx spares you can buy hardened steel gears which are the strongest like this TRX6491R and buy a steel spur too like this FTTX400
