2 race nights? thats crazy. Frank Root claimed he doesn't rebuild a diff w/ the tungsten diff balls until the outdrives wear out, and thats a lot of time on a diff.

What setup did you run on the XXX-SCT. Just curious what you like as far as setups.

I would go with some extra toe in for a loose track like that. Stock the truck comes with 3 deg I would go 3.5-4 deg of rear toe in. What compound tires are you running and are you using gladiators front and rear? For loose conditions especially I always try and run a harder tire up front then the rear. Not knowing how loose the dirt is but may want to try something in a M4 in the rear and M3 in the front if you like pro-line tires or Panther makes some great treads and a SS in the rear and a S in the front. Either a Raptor for med dust and hard base or a boa for deep loam.

I was optimistic with the Losi screw and thrust washers thinking I could get a lot more out of them than those "complainers". I was wrong, I do know a lot of 22b/t drivers who use AE diff parts and spurs.

I guess I just joined the "crowd".

I heard the same thing... Don't touch it till it goes bad or you wear out the outdrives!!! How do you guys break in a ball diff??? I used a drill.

Ran the new truck last week for its first race...

We run 17.5 blinky on astro turf. There where still a few guy out with 13.5 running some boost. So I tried not to pay to much attention those trucks. I had electronic gremlins all through qualifying but manages to Q-3 in the A-main. 13.5 ahead of me. I ran very close to box stock with 35 caster and schumacher mini pins. Everyone is still trying to get used to the new astro turf and the truck felt very edgy in the corners...

Truck jumped like a trooper. even with the 17.5 it was a pleasure to drive. So relaxed compared to my 22buggy LOL The A main started off great 3 of use took off in a line and battled closesly for a few laps... then it happened! BODY TUCK!! WTF???? Im not racing touring cars am i? Well i lost a few laps to it as none of the marchals i stopped infront of saw the tucked body! LOL Oh well i finished 4th but had a blast..

Tomorrow nite ill have the velcro on the nerf bars and body to hopefully stop that from happening... I suppose ill toss the nerf bars if this happens again though.. I may try to reduce the caster as well, but I will be trying out some Dboots multibites first.

Anyway love the truck way better then i recall my SC10 i ran a few years ago..

Ball diff is feeling great. I guess 17.5 will do that...

I would try 0 hubs and run the 30 kick. It makes it less aggressive but it still has a ton of steering..

I have chopped all the nerf bars off my trucks. I did that on all my Slashes, (yes, plural) it was the first thing I did on my XXX-SCT was chop them off (eventually went to SCB chassis) and it will be the part I leave out on my 22 when i get it.

of the two times I've built a ball diff, I have broke it in via the method stickied in this forum.
the method is the one where you go one tire to the other tire slowly building rpm and tightening the diff as you go.

I use a fast drill and/or the regular method. If the diff is directly going in the truck, I'll use the truck/buggy to do it.

I use my Hitachi cordless drill with a drill chuck installed. Hi speed setting is 600 rpm's, about the perfect speed. I can feel as the diff breaks in. Works great for me.

I just put my 1.5mm in the left outdrive and turn my throttle trim up to the slowest cog free speed I can get, for about 3 minutes, tighten and repeat until I hit my setting. I'll do something like mount tires or build shocks while it runs.

AndrewTom

so, you basically have the truck/buggy fully assembled (tires off?) with a 1.5mm allen drive in one outdrive holding it still while the other side spins slowly.

would it be necessary to switch the allen drive from one side to the other???

I do it with the tires on but not required. I run my diff both ways when breaking-in like Frank described.

i'm getting close to a rebuild on my XXX, so I will have to try that.
IMO, "there are many ways to skin a cat".
I have heard of numerous methods to break in.
