Hello could you educate me in what pinion gear would be best for speed runs on the arrma typhon tlr 6s. It has spektrum firma 150A smart ESC Spektrum firma 4074 2050 Kv brushless motor. Also has a 16T pinion and 50T spur gear with DBoots Hoons 42/100 2.9 belted speed tyres. Thank you

Mark / 27th March 2023

The maximum pinion that is recommended for on road high speed runs is the 20T ARA310967

Will this fit the kraton 8s?

Pete Holt / 31st December 2021

Yes if you have the standard motor with the 5mm shaft
