XRAY X4'22 Helpful tips & setups

Tips:

Installing the hex on the driveshaft - Make 100% sure you have the flat spot lined up on the axle with the cutout in the hex as shown in the manual. If you do not do this, it will make disassembly so much harder. The flat spot is there so you can fit a flathead screwdriver in between the shaft and the c-clip to pop it off when you want to remove the hex. Also, when removing the c-clip I would recommend pointing it down into your pit mat/towel so the clip does not go flying and disappear.

Assembling the upper arms - Make sure to grease the threads on the camber screw (302640). This will make assembly and camber adjustments much easier. Also, when adjusting camber you want to make sure you hold the upper arm so it does not twist while you turn the screw.

Droop - It is important to remove the shocks. All team setup sheets will show droop settings with shocks removed. Simply detaching them from the arm will do. This is a change from how we set droop in the past.

That rollover bent both the upper clamp and the lower bulkhead.

Anyone think the issue could be caused by the lack of body posts which used to help cushion roll over impacts?

Am asking seriously as I plan to change the rear body posts from vertical to horizontal on my current car (not an xray) but i would avoid it if this is a cause of concern.

I don't think it's likely to be the body posts. Rollover impacts do most damage when the wheels have a side impact with the ground. Landing on the roof does a decent job of cushioning the blow.

Have any one experienced missing parts in their X4 package? I already knew two friends with such experience - one is missing a damper shaft, and one is missing the a rear body post. While they can easily get the parts back from the distributor, it still not a good thing.

Found the security camera footage of the rollover that caused this damage:


Barely touched the kerb.

Wow there wasn't much in that rollover to cause that much damage. I'm not an Xray hater but it makes you wonder if it's a material quality issue or design flaw or both. They need to sort this out quickly because they've always been known for quality and durability .

It's definitely a design flaw. Mugen and Awesomatix have this part as more or less flat piece, while X4 has cutout for bearing, with notches even further reducing thickness right in the middle, in tiny spot.

Dump the fancy chamfer they put in it, that will add more material and give it some strength.
Sometimes fancy cosmetics are the devils tool lol.

You can see from the photo of Bruno's car above that they have already added an extra millimetre of material across the top of the clamp.

They've acknowledged this issue and got parts with a "production-quality" finish out on the team cars already. I suspect they knew these was an issue before they launched the kits (simultaneous global release means they would have been manufactured weeks earlier). Hopefully they'll have a care package for customers that bought from the first batch. I remember getting a stack of free parts from HPI after the Pro3 was released.

Unfortunately there are sometimes downsides to being an early adopter. If you buy the latest smartphone, it will cost more than if you wait a few months. And you may find issues that are fixed in later batches, like the iPhone that had no signal when picked up. Personally I've never purchased a car (or phone!) from the first batch. I'm happy to wait a couple of months and let others find the issues.

I think Xray said they had 15 prototype cars out in the world, so they will have found a good number of issues. But it's never going to find every single issue, especially as the cars were all in the hands of good drivers who rarely crash. The early adopters, like it or not, are still going to find a fair few issues on an almost 100% new design.

They had similar durability issues on an early XB4, and provided a free upgrade package to all customers. Maybe they will do the same here.

yup... Xray X4
and again the comparo with apple (tesla being in the same boat) is spot on, with the same strong customer/fan base.

the next MY will be a fantastic car

TLR is not a company it's a brand owned by Horizon Hobby.
TLR might not be a "company", but Losi IS. TLR is just the racing division is Losi...but, again, Losi IS a "company". It just happens to be a company owned by Horizon Hobby. Until HH purchased Losi (as well as the others HH has purchased), it was it's own 'stand-alone' company. Such is no different than other companies that have purchased other companies, such as when Dell purchased Alienware, or when General Motors purchased AM General (the original manufacturer of the HMMWV, aka Hummer). As for them supposedly "just started to get back on track", that couldn't be further from the truth. The 22 5.0 buggy has been doing quite well on diet/clay tracks for the past 2-3 years, just add the 22 4.0 did before that, and the 22 3.0 before that. The same can be said about the other TLR vehicles (22 SCT, 22 T). In other words, they've been "on track". It's just that TLR focuses primarily on dirt/clay, whereas XRAY focuses primarily on astro/carpet. It's no big deal.

I think that chamfer is not an issue, those notches are, especially the one in the middle - that causes that all forces from impact go there, because the rest of the part is much stronger.
It wasn't issue in previous cars, because clamps had mounts for suspension tower, which added lot of extra material.
it's interesting that it wasn't found during testing. Maybe there was some change late in the development?

Regarding the upper bulkhead clamp, I have noted that it can sometimes be easy to mis-align the diff eccentric in such a way that the nub is not fully seated in a notch... and if you tighten down the screws in this condition you could stress the part, or if you go run like this, the eccentric could seat itself properly, thereby essentially ending up with loosened screws holding the bulkhead cap down... all potential contributors to bending the cap in the event of a crash
