do you by any chance go to west coast rc? I'd like to see that truck run looks sweet

That's a little bit of a drive for me, so for now I run at Hot Rods.

Update
 

Ok, I was able to get out on the track this weekend (no racing, open practice) and test the Jammin SCTRC10 vs the Slash 4x4. There was also an Ofna Hyper SC out on the track as well. The Traxxas is a great truck and a lot of fun but for me the Jammin is a better racer (on the track). It handles a little better, is easier to drive fast, etc. One thing about the Traxxas truck if you race you need the center diff, it is night and day regarding the handling with the diff installed. The Ofna truck is very nice as well and between the two (Jammin/Ofna) they were pretty evenly matched. I saw no advantage with either truck when I was out on the track with the Ofna truck. These things are a blast, my poor 1/8's pretty much sat on the table.

cool pics I sometimes go to hot rod maybe I'll catch you out there one of these days

Could you tell me what the actual tire diameter mounted to the wheel is? Wanting to figure out speed and gearing with the speed calculator.

Thank you.

I think the outer diameter is 3.9".
