You cannot use yout 5R set-up on the 6 & expect it to be the same, it's not. That's just like saying I used my RC8 set-up on the 6 & it did'nt work. If you think the 6 does not handle as well as the 5R you just need to spend more time on the set-up. I seem to hit it almost perfect when I built it(no I did not use the kit set-up, I used a set-up based on an average of what all the world guys used). The only things I changed at the track was the droop & the ride height. Our track is way blown out by the end of every Sunday & I still feel it handles better than the RC8 I have had for a year.
