That was not caused by not using loctite. If you don't use loctite, the screw will back itself out (always use some when threading into alu). BUt break like that? Looks like defective material. I've seen COUNTLESS buggies with alu suspension holders running around the track, including novices crashing and burning like nobodies business, and have never see a piece like this break.

Deploying a product to the consumer will expose weaknesses that the design team had not considered. It happens to every product. I am constantly amazed at ways the users find to break the systems that I design. It is because engineers and users think a little differently and operate things differently.
It shouldn't be hard for Xray to trace the root cause of this issue. Be it a poor lot of raw material, an actual defect in the part, or a design without enough margin. I'm sure they will do the right thing.

I sure hope they keep an open mind about it and get to the bottom of the issue instead of just pointing the finger back at us. I follow the xb2 group on fb closely and I have seen at least 10 people break them. All said the exact same.. Had no idea why it broke and never once happened during a crash.

Sorry if this was covered before but to run the ae wheels. I need the 7mm hex front and 9mm hex rear?

I know! I Braught this up with Bent but he just pulled a jerk move and said it was my fault for not using loctite. I'm glad others think this issue is also clearly a weak point. I am a local club expert level driver, I have never broke a part minus this on the xb2. Bottom line is that this should be a part that should not break. Rc America made things right and is replacing the part for a discounted rate but now I am also going to carry a backup rr hanger.
And you must be a much better driver than all of us on the team. For the past 2 years with 20-30 prototypes and pre-production cars running full time on the track we've not broken a single hinge pin holder but tons of suspension arms, uprights, front chassis upper and lower parts, bent hinge pins and broken hinge pin inserts.
And we still break parts on the production cars we are running now

And I also report back on finds and issues.
Jusy like this issue have been discussed.

I'm the one administrating the groups on Facebook and including your issue we've had 4 in total, not 10.
That would certainly point towards there being a materials or engineering issue. And selling you another part at "a reduced rate" would be inappropriate. We will see what I get when I start running the car (dirt). I ran my B5m for almost 2 years and didn't break one-single-part. I would imagine that the Xray would be even MORE durable.
The solution is to use Loctite on the screws to make sure they don't come loose and protrude through the chassis.
However I'm not saying that for a future release there could be a revised version of the hinge pin holder to make it withstand the stress from a screw coming loose.
But for the moment the solution is to use Loctite to make sure they stay in place.

Running the shocks on the rear will give you less rotation and calm it down some as well as provide a bit better bump handling over small bumps/ripples (provided you add back the lost droop by unscrewing the shock rod ends 2-3 turns).
On high bite we always run the shocks to the front for better rotation in corners

hinge pin brace
At the last race in France, 2 friends of me broke the rear hing pin brace like suby.
