PV- any reason why only the 18 XT2 has the new larger O-rings and not the 18's XB2 or XB4? I was going to run the bigger O-Rings on the 17 XB4 unless I am missing something? Thanks again.

I can only guess that they were having more issues with XT2.

Been running the xt2 o-rings on my xb2 18 and am loving it.

Pretty sure the 2018 Xb2 comes with the larger o-rings, at least that's what I was told by an Xray representative.

I'm sure it's been discussed before, but I've done a little searching and haven't been able to find anything. Can someone make a recommendation for a good starting point for center diff fluid for the '18 XB4? Indoor dirt, low grip. The track is hard packed but will almost always have a thin layer of fluff/dust on top. While we're on the subject, does anyone have a good baseline setup for such conditions? I'm wondering if the standard setup in the manual isn't geared toward more high grip applications. Thanks in advance!

This weekend im going to do my first rebuilt run with mine in similar conditions (though outdoor). Tracks here are also generally also rutted and bumpy. Out of the box my other cars were much better suited to the conditions.

Things ive changed:

550 shock oil front
500 rear
500k centre diff, 7k front, 5k rear. I wouldnt run 500k in mod though.
Medium chassis side guards
Shocks rear of tower
Thinner sway bars
Aluminium diff pins

Ive also got a couple more things to experiment with - the more reward motor mount, medium arms, 12 degree caster blocks and ball diffs.

This car should be great once i tweak it. I hope..

Go light in the center like 15k or 20k, Tires wear evenly using m4 hole shots/blockades, it has been proven to be our starting fluid for when it is loose. I thought you had to use at least 100k in the center because of this thread but that's not the case. It only takes 15 mins to change it if you don't like it. Try slightly thicker in the rear then the front to help prevent the rear end from over rotating. These buggies have plenty of steering so the slower rotating rear end helps if your a little too heavy on the trigger finger coming out of the corner. If you try it let me know what you thought

Hmmm interesting. Will definitely give it a try. As you said, this is rather against the wisdom of the thread.

Can you use the slipper instead? It would be much better on that type of surface.....

Another thing to note, especially on low-ish grip, is that with the updated 2018 shock internals you probably would want to run lighter oils than what is included for the '18 kit. Something more like 425 or 400 in the front, 350 or so in the rear. And definitely a slipper.

Thanks for the info guys. Iíll try some of those suggestions. On a side note, does anyone happen to know how the front and rear wheel offsets compare to Losi 22-4 wheels? Would like to run yellow wheels.

The XB2 18 came upgraded shock o-rings from the 17. But the XT2 comes with a slightly larger o-ring 3x2.1. This is the newest o-ring out and works better then the XB2 18 rings.

and the 3x2.1mm oring is impossible to find in the US. I haven't tried rcamerica yet tho. I wish they would get the e-shop running.
