I never believed how strong a B4 is until I saw my brother bash his yesterday......flat out amazing that nothing broke. I think my favorite was when he came up short on a jump big time, and not only "lawn darted" into the face of the landing, but managed to kind of pogo off it and drive away. There were also many many upside down landings and hard chassis slaps, as well as even more hard bounces off the landing ramps.......sucker's truly built like a tank, amazing for a light and super performing race buggy too.
