As long as you downgrade to the older style 14mm Hexes yes they will work no problems. I prefer 17mm over the 14mm personally but if you have a bunch of wheels/tires that need ran, there is nothing wrong with it for bashing.
All Revo models and the EMaxx do come with 17mm, The T still comes with plastic 14mm. I never could understand why the new 4908/7 models didn’t come with the 17mm, they were available at the time they were released. I guess its just another way for them to sell upgrades.:thumbdown:
