was able to make the gearing work 54/18 but speed was only 25mph i have new hyperion batts, its got racing tires maybe a hair taller than stock, i recalibrated the esc to tx, , i contacted the seller to see if he changed any tranny gear , the truck was acting as a summit when he had it not the case. then i thought my motor is not a 2000kv but it rips in my 3906 e-maxx with 70/18 geared i dont think the motor is less than 2000kv, somrthing is not adding up
