Top speed on the box for the RTR says 50+. I dont have an actual radar gun to give you a top speed but it is very quick with the stock XTM .18. I have bashed it very hard, and it is pretty sturdy with a few upgrades. Aluminum hubs front and rear and RPM ballcups are the only "upgrades" I have made. I have broken the one front and one rear arm, but that was from horrible landings.
