It can't be happened..
I bought it because my sabertooth has been damaged in shock shaft so i bought it.
But it's not suitable my saber. so i complained about this problems they didn't agreed about this problems.
old ver. okay. but 4mm ver. sabertooth is not suitable.Very soft, will bend even medium jumps. I tried the optional hardened shaft but even they are not hard enough (bent 2pcs after 1h on a race track without any crashes).This Shock shaft always bent easily after jump :) need more strong one
