pretty fast for a straight out of the box rc, make sure you get that extra battery to get the full 50mph speed that is advertised. only negative thing i can think of is that traxxas needs to start making replacement bodies for this mustang boss. And im talking about all ready painted and stickers applied bodies. i dont want to settle for a ford fiesta body. Overall I give it a 10/10! love it and its lots of fun! great for a starter rc as well
