Been following this thread since it's beginning, and I'm sort of an AE fan having owned a T4.2, T5M, B5MFL and now two B6s (mine and my 11 yr old sons). We run at DRPRC in northern PA (indoor ozite). I've been patiently waiting for the carpet muncher. I've joined the B64 group on FB and a few things have sort of caught my attention.

There's a video on the FB page showing a XB4 and a B64D side by side, and the poster does a decent job of showing the differences in drag & noise in the drivetrain. Seems to me the B64 might not be on par with the XB4. However, there are a bunch of unknowns, like how many hours are on each vehicle and is that the reason the XB4 is "looser" and quieted than the B64? Or is it an assembly thing, b/c that doesn't seam to be internal to the diff, but rather in the bevel gears feeding the F&R diffs.

Stupid comparison (....or not). The XB4 already has composite gears in the diffs. Its not apples to apples (but I hear the the test AE car did too, I guess I'm wrong, I lied).

Secondly, there are a few people complaining about the front arms breaking, and quite honestly, I've marshalled during the 4 wheel buggy race and watched some XB4s take some amazing cartwheels and flipped 'em over and off they go. Does somebody out there have a good "feel" for the strength of the car vs. the X Ray?

I don't have enough time on the B64D to know this but my guess is that as of today the XB4 is better quality. I ran the XB4 2016 for a year and the front arms are the only things that I ever broke and it only happened once on each of my 2 cars.

Then there are the parts costs, where the AE parts are a fraction of the X-Ray. The LHS at DRP carries a pretty good inventory of both X-Ray and AE parts so it's not so much an availability thing as it is a cost thing. Seems like if it says X ray or Hudy the part cost suggests it might be gold plated. So definitely a feather in the B64s hat.

Parts availablity for XRay is the worst. Period. Can't count on their supply chain. I loved the XB4 but when stuff is out of stock, its out of stock. I'm an unlimited sort of guy but cost on XRay parts is the same or more than retail of anybody elses stuff. Its so expensive to rebuild an XB4 that its not worth doing. You're better off selling and buying a new one if you want your car fresh.

Pretty much all the fast guys in the wheeler class cant say enough good things about the XB4, and rather than be a "me-too" I'd like to try the B64...... but am I letting my brand loyalty cloud my vision of what would be the better choice?


As much as hate TLR the 22.4 2.0 is a great alternative to the XB4 but I'm hoping the B64D is good too. I'm not an RC superstar so I don't need the cutting edge "best-super-all-pro" cars. I have a lot of cars and just being able to carry one brand of semi-interchangeable parts is enough of a benefit that if the B64D turns out to be in the ballpark in terms of performance compared to the other good cars, that'll seal the deal for me.

What's the general consensus?

Bezerk B64 Parts
I added them to the Wiki page

If you asked me today, right now, I'd say the TLR is the best choice (without having any time on the B64D) but its a royal pain to work on [and its a TLR]. That being said, if the AE turns out to be in the ballpark of the other cars its a better balance in terms of the bigger picture. When I say big picture I mean the other factors that make a car good or bad such as cost, support, ease of maintenance etc. How many big races do you go to in the US where there's a bunch of guys that can help you out with your XRay or, much less, loan you a part or something?

I drove a TLR and it blew me away. Loved the car, but the b64 is better IMO. It turns just as well for me and lands just as well, but it is vastly easier to work on. It may be more planted too, but I need more time.

As I mentioned before I do not think the "growl" or drag is internal to the diff. I believe it is too tight a shim job between the bevel gears. The X-ray offers a composite bevel gear 365114 to replace 365134. AE doesnt yet.

I bet that FB video comparison prompted AE to release this.
