Ah ok. So it's always the smaller diff pulley that takes precedence. Thanks.

Default Fisrt track appearances

I am looking at spending sometime traveling this summer, and bringing my xxxs with me.

What I want to discuss with you guys is what do you do when you walk into a forign track. I am new the TC scene, but have raced Losi (in the dirt) since the jrx2. I know the race basics, but I was looking to find out what you guys do when you roll into a new place (or even the old place with a new track).

Specifically:
How do you determine tire combos?
Motors? Gears? Shocks Springs?

In dirt, I usually start by guessing the tire combo, and work on the shock package. I usually will have my "pit boss" (good friend), with a handfull of springs/shocks(varied oil/pistions), in case I am way off or really close and want to dial in. In dirt I usually have 1 or 2 setup(s) per vehicle (plus shock/spring combo) depending on surface.

But TC there seem to be a huge disparity of surface conditions and what works well. I have seen over 30wt in oil and several spring / piston combos that are on the fastest cars (even on this board...) I know its feel, but from the newbies eyes this can be daunting...

For the record, I plan on running at tracks in NJ, NY (eastern), CT - rc madness, and big boys in mass, so I will take any setup ideas you have to pass around for them. I don't plan on racing at big boys this weekend, though I will try and stop by.

thanks.

I'm not sure if anybody has posted one before, but is there an easily accessible set up for foam mod?

I ran it for the first time last night, the car was not terrible with a blue/silver 60/60 setup, low roll center, no swaybars, longest camber links, 4 degree front caster and 1 1/12 degree rear toe-in (total). Plaid up front and purple rear.

I know it can be better though. I will probably try stiffening things up a bunch for starters. Anything else I might try?

Thumbs up Milled XXXs

Anyone interested in a milled XXXs car please IM me for details and pictures. The car is very similar to that of Kinwalds. It has Lunsford titanium hinge pins and turnbuckles, Losi titanium ball studs and threaded shocks, Dynamite graphite front and rear shock towers, Speed Tech aluminum front and rear low roll center blocks, pivot blocks, and steering linkage.

Default part number for cvd bone?

I just managed to break a front steel cvd. I need to replace the bone only, can't find the partnumber for the bone. Is there an alu replacement bone? I would like to put it in the back to save some weight.

I had the same problem with the steel dogbone part number. My local hobbyshop had to call Losi for the part number (it's not on the website). You might drop them an email. they know about the parts database being out of sync.

Default "Slim" Diff??

I was reading about a diff mod on the Trinity forum, the guys there called it the "Slim Diff" supposedly named for a guy named "Slim" at Socal. They said that building the diffs this way would be better than the kit specification.

Anyone using this mod, There seemed to be several variants on how to do it on Trinity's site, I'd like to get the lowdown if possible...

Thanks,

Trips
