The key here is that the plates hit the gear when they broke in. I have experimented with less than designed diff balls many times, in an effort to reduce spring pressure but diffs need to be broken in to work with any real amount of torque. Running less balls (hehe, ok grown up again) is an oooolllldddd pan car trick and nothing weird. Sometimes the diff spring (even new) is too weak to spread across so many balls (in a smoothness losing move) run 2 or 3 less and remove evenly around. I've been known to pull 4 out of 14 or 16.
The new gearbox looks fantastic. They say stronger plastic, one of my complaints with the 3 - 4 platform. Carbide diff balls in the kit -- great call. Durango gives you aluminum balls in the kit and they melt with a 7.5.
I hope the rings are keyed -- I get annoyed with having to ca them.
The reason you dump your 4.2 is easy -- this car looks fantastic -- they claim to have fixed all the things that sucked and were antiquated. The insert thing is just plain easy and smart, and the 5 positions in the rear is a nice touch. Finally, a new gearbox and proper metric hardware. The new slipper was great, leave it alone, the new turnbuckles and ball ends look great, the old AE ones (and the RPM equiv) were long overdue for an overhaul.
I'm willing to replace arms often in exchange for less weight, however it was a bit out of hand with the 4.2.
I have to say, it looks like they hit this one out of the park

An additional function they provide is a 'safe' place for the diff to 'give' before slipping the diff balls. An example of this would be when losi went away from D-rings in their XXX platform and have continued the trend of all the other good diff makers like AE to use non-keyed diff rings. I could see how this would be different though for on-road.

B4.1,2 Diff outdrives are already metric (10*16mm) I use it on a Bmax2 car thats all metric.
The idler gears could be bigger in dia? I know they were a weak Point on 4gear boxes.
But have they changed the diameter of the diffgear to ?
To race this on Astroturf you will need a geardiff for good lap-times (1 sek a lap) and a ball diff wont last a day on a high-grip astro track...

I don't know why you would want to CA your diff rings in place?

I've never used CA to hold my diff rings, but I always preferred that they were keyed.

@Wildcat, I thought the same thing...lol
Bottom line, non-keyed diff rings are not bad, especially in off-road.

From what I recall, I think at the worlds the 22-4 had a lot of drivetrain issues, either slipper or diff issues. Regardless, the fact that their 2wd has non-keyed diff rings and the 4wd does just makes me think that they do not have the best idea on what they are doing in the diff department. I would look at diffs that have proven to do well and Kyosho and Associated certainly aren't keyed.
Never said they were, just stated my preference for ones that are keyed.
