Use 2.5 mm balls in CRC spur gears (#1227), they "pop" in and stay in. The diff builds excellent and is WAY lighter than 1/8" balls. Spinning weight reduction... always good.

Are you sure it's a 1/12 axle and not a 1/10? The shaft looks too long to me. Might just be the picture, though.

Why are your axle spacers sitting between the axle bearings and not the hubs and bearings? That could be what's up with the diff not tightening. Spacers being used in the wrong locations.

So this is where i am now. The diff will tighten but I'm going to replace the flanged bearing in the hub, because it feels like crap.

This pic is what took me down this road. Its how the car was delivered. If i could just find a online manual i would tear the car down complexly and rebuild it myself.

Pod/Rear axle assembly are basically the same between the WC and standard XTi-

I have the slapmaster kit with all three spacers so that shouldn't be the problem as I used the one that was closest to just cover the graphite end. I just read later in the thread that they have changed the axle and it doesn't get enough thread engagement using the thrust bearings. I think they have suggested using an older axle. I will look into this and see what I can find out. I really liked how the slapmaster bearing made the diff smooth on my 12r5.2.

Do you happen to know the part number?

Got a new bearing coming and got a new cone washer. Just how tight should the diff be? Should i be able to move the spur or should it be locked down? The only other pan car i had was a RC10L, yes that long ago. By the way i got tired of trying to remember how to calculate roll out and just built a calculator. Let me know if anyone wants a copy

Jon, about a year ago CRC made a running change to their 12th scale axle. The axle from F-1 and 12th are the same and use a shorter 4mm thread stud. There is not enough thread stud to install my thrust bearing and to get enough into the nylock of the nut. In short, there is no way to install my Slapmaster thrust kit on the 4mm stud axle.

If you have the older 8-32 stud axle, you can install a thrust kit. If you use 1/8" diff balls, use the #101 kit. If you use 3/32" or 2.5mm diff balls, use the #120 kit.

Dude, I was not aware of that. Thank you very much for that... I was so disappointed about running my car without your thrust kit...

I'm gonna recycle my XL axle :-)

Not sure why CRC would even need to release a new version car considering that Andrew Knapp just swept all of the 1/12th scale classes in Vegas with their existing platform. This with many of the most talented drivers from all around the globe in attendance, so his dominance was certainly no fluke. Oddly, I've not yet seen the usual victory photos and/or setups posted from Andrew's winning ride(s), but I do recall reading somewhere that he was actually running standard graphite chassis plates and not the optional alloy that many consider so advantageous for running on the new black carpet.

There was a prototype ran at the worlds and they were working with it in Vegas as well. No real word of when it will be released though. The current platform is still very competitive.
