Sc10 gets it done again !!!

I helped build his truck but Scott may had made changes when he got there .

Will post the set-up after I talk to him later today

Race was at Intermountain raceway in Utah , its indoor clay with med to high traction conditions ..

Shark , maybe a lock up Cdiff ?

Will strip rear diff & spurs .
Check the adjustment ...

WC, I will thanks. Possibly too much brake, high traction, loose mesh contributed to the stripped spur. Truck sure was sweet prior to the spur issue.

check Cdiff by holding all 4 wheels and push the spur by hand . If you cannot make the Cdiff slip ?

That could be the problem ...

Again those who say the truck has issues proves to everyone they are inexperienced and only have a big keyboard .... :nod:

The truck running great on the conditions you mentioned are not the conditions that people have been having issues on WC ...

Great result though, truck does have the chops especially indoors.

A locked up Cdif would be just like a slipper......
How many ball difs have you seen lock up?

WRONG AGAIN, I know you are trying to be helpful but giving information on something that you have no knowledge of helps no one and only causes frustration and confusion.

Shark, proper way to set the center dif is to tighten all the way down so that the spring is fully collapsed and then back off 1/4 turn. If for some reason you get some kind of slip then simply replace the spring, they get hot and weak over time. The only possible way the Cdif could lock up is if when assembling it one of the dif washers slid down and you didnt notice it. If it worked from the beginning its not going to "lock up" out of the blue. IMO your mesh was either too tight or the center hole on the spur is wore out ( unlikely but possible)

Shark, is it possible that your motor mount itself may have been flexing? Different vehicle type, but I remember that caused us some spur gear headaches with my Academy 2wd cars till PSI Racing made a thicker motor mount plate.

could be way off here though, just thought maybe it something to look at as well for replacement in case.

Marcus, thanks for the feedback. Yeah I don't think it is an issue with the cDiff (great product by the way). I have been using it for several months (maybe half a year) and no issues. I still think it was a combination of a slightly loose mesh, maybe some flex, too much brake and too much traction (slicks and sticky clay). I just took a quick look at the track, I will tear it down this week and take a closer look (especially the mesh).

Cain, I got my first SC10 4x4 back in May 2011 and a second one (FT) in June 2012. I never had an issue with the spur. It has to be a mesh issue, where I just had too much play.

simple question, shock setup:
bladder or emulsion?

when to choose which setup and why?

any thoughts out there?

sounds good! When you do your tear down if you can post pics of your findings that would be great, may help someone else with a similar issue.

Bladder's add pack which helps on the landings off the jumps .

Emulsion adds traction compared to the bladders improving grip .

Anybody try raising the front camber links like max's setup sheet?

Cain 04-08-2013 04:39 PM

I did that on my carpet setup from the 3mm I was running outdoors to take away a bit of the front bite.
