Yes there are some upgrades out there, but not nearly the same as traxxas and arrma. Prices are higher as well. I just ordered 3s batterys and rpm control arms so i had them on hand
So just getting back into the hobbie after many years. After research i narrowed down to the mt10 or the granite. Ended up with the rival mt10 due to it being about 50 bucks less and the good reviews it had. So far i love it its been below freezing every time i have run it, and nothing has broke...
