thanks guys...i am going for rtr just because of its ease...though i will loc-tite EVERYTHING. the hyper does seem like a better racer. i already have an xs3 and a 9645 in my savage so, i'll buy a new receiver for it too. if i'm not minstaken...the difference between the pbs and pcr are the laydown servos...are laydown servos better? lower cg, but wooop, servos aren't very heavy, nor tall. pcr or pbs and whats bad about this buggy?
