Anyone else experience the extremely short lifespan of the EB48.4's 13x19x4mm inner hub bearings? Seldom, if ever, can you get more than 1 or 2 races without this bearing feeling very notchy and unsmooth. I kept a tube of replacement bearings, with a regiment of checking them often. Failure to do so would inevitably lead to an ill-behaving car or a melted plastic hub due to bearing failure (lockup).

Thank you my friend. I have always been a 10th scaler, thus really will be my first true 8th scale. I guess you could call 4wd SCT 8th scale. Anyhow will be exciting as I really will be able to take advantage of our local 8th scale track.

what means ROLL?
Please help. I am trying to learn more about set up. In the TLR 8ight 3.0 Tuning Tips, it says in the section front camber link: "the longer front link will keep the buggy flatter, with less ROLL...Short camber link will ROLL more.
What do they mean by the word ROLL?

Seriously though, I've for some reason liked shorter link up front, and longer in rear, or shorter all around.

What do they mean by the word ROLL?
1.) seat of the pants, opinions of what "ROLL" is (will greatly vary from racer to racer and chassis to chassis)
2.) information on suspension theory that requires a little more education to further understand what is called the "Roll Center" and how the adjustments (camber link locations, hinge pin locations and center of gravity) affect it.
For number 2, here are a few links worth looking at for a start:

Picture an antenna tube sticking up from the center of your car directly above your front diff. As you go through a turn, you'll see the tube lean. The further it leans, the more your car is rolling.
So what that means to you:
As you roll you build traction, until you get to a point where you roll over too far. Then you lift weight over the inside wheels and grip goes bye bye.
The same holds true for the rear of the car as well.

I get more than a couple of races on 'em, but they do get gritty before all other bearings on the buggy/truggy. I've been replacing them once a month. I will say that I do put in quite a bit of track time which could contribute to the wear I'm seeing. I'd like to see them upgrade to the 15x21x4, like the new .4 cva's, across the board for buggys/truggys.

Good info and excellent place to start learning process. Read all the setup guides you can. I find that each one seems to offer some insight that covers something I didn't know, had forgot about or just explained it in a way that made the light come on about the subject.

I've had to replace 1 that felt not so good since I got it. I've been running it roughly every week since it first came out, and on rough and blown out tracks with lots of dust. They are expected to need replacing faster than the bearings from the CVDs, because the geometry of more leverage against the bearing to put the joint in the same place makes this happen. Folks shouldn't be going through them every race day though without something else being wrong.

Apparently, my kit is one of the new ones from the different manufacturers, don't have the bearing issues, but have a major other issue. The pins in the drive shaft pop out. 2 packs in on a brand new car, and the driveshaft pin decided it didn't want to stay. Emailed them about it, waiting to see what's up. It happened after downsiding a small jump so no crash involved.
