claudacio...
Well... the guy I got it from put 7k/10k/3k in it, but I can't say for sure. I checked the rear/center and they were filled with something (not sure though). I did however put 3K in the rear when I rebuilt it last weekend. I need to refill the center diff though... I am running 7k/10k/7k in my Hyper... the rear was a mistake, but for the (BYB) track we are running it works out pretty good. It pushes a little in the corner, but that's probably cause I put the 7k in the rear. The next rebuild I will probably drop it down to 5k...

As for the feeling... It felt like it was running only FWD at the end of our day. It was making that sound like a thrashing diff... but I have not opened it up yet. It's getting late now, so I guess opening it up will pushed off until tomorrow. The front wheels were turning no problems...

GNX5T...
I know Axial has something to do with Robitronics... not sure about the HPI thing though, but it seems HPI is trying to put their hands in everyone cookie jar. Not that I am upset or anything as I am fan of HPI products

I haven't had any issues with the steering as I replaced my servo with a Hitec 5645MG... I will have to check servo saver though to see how tight it really is.
