To be honest with you, i don't have try it yet, because here in Quebec, we have about 4 feet of snow
And more, i've remove all the brushless of my MBX5 and re-install it in my revo.
My MBX5 is for sell, because i just bought a Baja 5B SS. I'll keep the révo to play with my kid when we go on campground (he have an electric Stampede).
