My son has (2) DEX210's and he's always had good luck running RM. I've got his other one setup with MM4 with the stock kit chassis. Anyone with any recommendations on a setup for a track that has a gear ratio of 69/32 and we run Panther Slicks. I'd like to provide a good setup so he can actually feel good about the setup. Most I have found are for sugar tracks. PetitRC seems a little dated on setups too. Thanks
