Yup, TC gots a bit of work to do yet before they're a threat to an Arrma IMO. I definitely like my Kronos, but it ain't Arrma tough..Oh yeah. I already put Typhon 6s upper control arms on my Sketer (I broke the stock one) . I also put a rear rod end from a 6s Arma (rod end and ball joint) to replace the rod end that I broke on my Sketer
