Lots of transmission/spur play!?

[Haziza]

Transmission and spur gear has a lot of play in it and wobbles like crazy this can't be normal? Anyone else having this problem?

Bad bearing..... Or bushing
There is one in the center of your spur . I run a Robinson Racing metal spur with a bearing. Pull your slipper out and check

If that's ok you could of broken the e ring on the shaft behind.

Mine did the same thing it does not have to do with slipper bearing. That would make it wobbel up and down not side to side and the shaft Is sliding to... Mine looks like the metal gear that is in the transmission where the pin goes in is machined to deep allowing the shaft to slide .side to side. I contacted axial and they are sending a new case and gear. I will see if this helps when it gets hear

Many new kit owners have this exact problem, including me. It is very common.

Strange in my manual it dose not even mention the e-rings.

My manual is like yours, and is also incorrect on other pages. I too have the sliding shaft issue. So far it's been ok, but somethings obviously not right. Until something fails, I'm not taking it back apart.

Looks like the manual he was referring too was from the original SCX10

No offence but I suspect you may have assembled it wrong, there is some play normally, but not as much as you are having.
Check that you have the correct length plastic spacer tube (parts tree 31375) there are three different lengths - make sure you have installed one the correct one.
For the assembly order left to right with threaded end on left, you should have bearing, 30168 cross pin, 31126 gear, 31375 plastic tube, and then bearing.

I have a kit on the way. Should I be worried? Or are there ppl out there with the kit built and no slop?

If multiple (many?) people are having the same issue, it's likely on Axials end. Whether the product is wrong, or just the instructions are wrong, is somewhat irrelevant to the end user. I followed the directions "to the T", and have the same issue.

Mine was fine. I got a kit from the second round of shipping. Yours is likely from the 3rd round, since you are getting it just now.

I did open the transmission up again to figure out what is wrong and I think the problem is the top-shaft.

It is to short, that's why it has so much play and wobbles! Look at this picture.

Yep, bad design and poor execution just like everyone's been saying about this turd since the first shipment. Let me put it this way, had they shipped all the new SCX10 IIs with the tried and true AX10 trans, there would have been a lot less complaints. There's always a few people that bitch no matter what and it's impossible to please everybody but at least we would have had a proven trans that functioned well. If they really wanted to add some more scale to the new II, they simply should've given us an interior instead of this awful trans. I'm still waiting for someone to come up with some kind of real actual advantage or benefit of this version 3 Yeti trans over the AX10 trans. All I see are disadvantages.

I have found the fix for the wobble while assembling my SCX10-II today.

The first slipper plate does not have enough of a step (shelf) on the upper shaft therefore causing the plate to have enough room to wobble because it's not completely stabilized.

I added a washer to the shaft for the first metal slipper plate to tighten up against. Washer - 11.85mm OD / 5mm ID
I also used a bearing in the spur gear instead of the bushing, but this has no "bearing" on the wobble!
Then I used another washer (same size) up against the outside slipper plate before the spring.

I hooked up all of the electronics to do a bench test and the spur has zero wobble now. Prior to the washers, I could turn the spur by hand and see the wobble.

Open up those spur covers and add your washers now!

BTW, the upper shaft has a bit of play in and out, but that won't affect anything as long as the pinion is located on the motor shaft correctly so that there is always gear mesh without binding throughout the minor amount of in/out travel.

[SCREAMER]

Nice Bil, maybe you should work for Axial. They probably can't afford you.

[yellowdatsun]

At least a fix we can do without taking the whole thing apart. Thanks!

I still agree that this kit is a turd.

I bet losi and horizon could make a better scaler than this.

But they haven't ........

If you don't want to tinker don't come out to play.

[1967Typhoon]

Losi doesn't make kits!

TLR does. So unless they made a TLR-branded scaler (why would they) then we would get yet another RTR shoved up our butt. Just be happy kits exist anymore outside of the racing segment.

Can you imagine how hard it must be to design, engineer, test, quality check, package, and serve support for a kit with well over 200 pieces in it? I'm not surprised that there isn't MORE wrong with it. Were there some design choices that were questionable? YES. Were there some unclear instructions at some points? YES. Did I have a piece or two that wasn't quite right? YES. Was the truck fun to build? YES. Does the truck flat-out perform for a scaler? DOUBLE YES. Some people won't be happy no matter what. But calling the kit a turd? Not in the slightest. I say hats off to Axial for improving the platform, and still giving us a kit to build. It looks great and works great.

[SCREAMER]

Just to be clear. Love the new kit, hate the new trans. It was a total waste of R&D dollars for something that gives no real performance or scale benefit. Axial could've done something better with my money like an interior or beadlocks or something. We know the AX10 trans is better and we know it's cheaper because it's in the RTR.
