Big e- Thanks for the reply. Now that you mention it, that does make sense

. I had the rear diff accessible tonight and I didn't even think of adjusting it. From just looking at the diff it seems adjustment will not be too difficult, but if you have any tips you could share that would be great.
I can't wait to get this car running as I have a feeling I'm going to love it. I used to own a xx-4 some 6 years ago and am just now getting back into the hobby. Am glad I found X-factory before I jumped into another losi.
Also, I have a brand new 104(black) tooth spur gear that I was thinking about installing when I put the new drive gear on. Would you still recommend the 17t pinion or would you run a larger pinion, say 18-19t with the 104t spur. Mind you this is with a NOVAK 6.5t GTB velociti system.
Thanks again.
