Ok I am now a believer in the RCShox CDiff, night and day difference at the track last night.
The car was way more consistent that it had been with the VTS, I was making jumps with just a little blip of the throttle that I used to have so much trouble with, just because of the inconsistency of the power.
I am basically running Sharks "Lite" setup at 4.6 lbs with a 8.5T LRP 540 motor "picked it up used for $20", Hobbywing SCT and Reedy 3800 Shorty packs, 6 pins in the diff, plenty of power and punch, actually did a couple of drag races with my buddy who has a Losi with Tekin pro4 4600 and it was almost a dead heat. Loving the truck now I was very frustrated before and actually have a Tekno on order but after the CDiff I might send it back.

My only complaint is the fuzz on the gear from the drilling is there an easy way to clean that up? Not dissing your product, it is what it is, but spent a lot of time getting it ready to run, but it was worth the wait.
