Do you mean the centre dogbones Shaun? I've got two sets of those, one stainless steel from RCAlloys, and one hardened steel from Mike
I was running 30k before, it tamed the power down nicely, but im aiming for a little more crazy this time. I was expecting little hiccups here and there, another couple of runs though, and everything should be sorted. I also think that the batteries will gain some performance when i put a couple of charge cycles through them, still on their first at the moment.
