Hey there, I was wondering if anyone knows what are some of the best upgrades for the DHK Maximus. It’s coming in the mail in a few days and I have issues with leaving things stock. I’ve been reading a lot about the truck and haven’t really pinned down too many upgrades like tires, gear oil for the diffs., what gearing to run and where to buy them. A metal spur gear. Better suspension tuning etc... I ordered better batteries and a Servo... any tips would be gladly appreciated.
