Has anyone changed up the regular gearing on arrma granite. Any good results? Im thinking about going down a pinion gear because of the weight of a new bumper and wheelie bar plus a new .6 body. I lost about 5 min off an hour run because of it. No heat issues still around 130~140. I will try a 5000mah instead of the 2000 before i do mess with the gears. i have had only one issue with the gears and that is my transmission became sloppy after my first few mud runs. Sent it back to arrma and they fixed it within 3 days. very nice! Has anyone played with granite gearing. Im sure the 15t cant take much more but a brushless could.
