I wonder if I can convert my b64 to a b74.....LOL

Time for a new thread

Interesting choice for diff height adjustment. It raises the entire assembly, shock tower, inner hinge pin location. I wonder if they were unable to accomplish it with the spacer layout the B6.1 uses, while retaining the quick-access feature? I guess it probably helps to reach the low ride heights desired for carpet. Adjustable dogbone length also looks interesting. I'm a little leery of the Schelle rear hub design executed in plastic.

The aluminum piece is the actual bulkhead. The plastic diff case will mount inside and be "floating" in comparison to the pins, tower, ect ect. So moving the diff up and down will only move the diff, nothing else. This wasn't the case with the b64 and caused a multitude of changes when wanting to alter the diff height.

...and if I am not mistaken, you only have to remove two screws each and maybe the sway bar to access the front and rear diffs. I like what I see!
Dogbone length will probably not be adjustable on the production car, too many potential issues. With the inserts used for adjusting diff height, the process will actually quicker and easier. I think they nailed it once again!

Yeah remove the roll bar ends and 2 screws on each side of the bulkhead, so 4 to remove the diff case from the bulkhead and then 2 to open the case. 6 total to have the diff in hand. Can't wait, they checked off a lot of boxes that were left open with the 64.

Or now that I look at it you may only need to remove the front piece of the diff case instead of the whole thing. So 4 screws?

Oh yeah, I see it now. Thanks.

Pics of the new b74 on live rc. Reminds me of the yokomo yz4 sf.

I hope that the top two screws will be all that must be removed. Loosen the sway bar ends, remove the two top screws and pivot the diff case down. There seems to be enough space in the D block. Time will tell!

I'm not overly familiar with the yz4 but when I saw the new rear hubs and the chassis brace style the 2019 xb4 was what came to mind.

Yup on the braces and hubs. I am pretty sure the hubs came from the yokomo 2wd side... Not sure who did that style first yokomo or shelle racing. the aluminum around the diff cases up to the shock tower is definitely the yokomo and then the chassis braces are also on the yokomo, but not sure if xray had them first or not. Right now seems to be a monkey see monkey do across the classes. Only a few brands are trying to be different and doing their own thing.

Either way it looks like it will be a good buggy. Heck any buggy can be a good buggy in the hands of a good driver.

Yokomo and Yokomo. When people claim something is an XB4 copy, it is actually inspired by the general design of the B-Max4III, the Xray still used top decks back then. The Yokomo hubs and Schelle hubs were released almost at the same time, and in this case I'd not assume one copied the other. As they say, great minds think alike...

Hello, is it normal for the B64 stock body to be so large with respect to chassis? That's the one included in a new kit and I would expect the body to "hug" the chassis.
Is it possible that the included JConcepts body is not for B64?



Like this it cannot stay fixed with juts two clips, and for me there's too much of a gap to apply velcro either.
Thanks for any hint or eventually sharing pic of how your body fits
