Hey Boz I think those diff gears are for 1/8th size active diffs, too big (XB9). With the info from the guys above I’m assuming the diff gears from the nitro 1/10th on-road car Xray NT1 would most likely be a direct fit. Part #XY335030.

But all speculation at the moment to start changing diff gears, will have to wait for all the guys who have their buggies to get some laps down and see how the stock ones go..

READ THIS, IMPORTANT INFO!

I started building mine last night, and found something:

The manual says nothing about using shims to get proper mesh from the crown and pinion gears in the diff casing. There are no shims supplied either.

BUT, I had to add 0,2mm of shims in the rear diff, and 0,3mm of shims in the front diff to get perfect mesh.
That is quite a lot IMO, but not all kits will be the same so check yours while building. And check your car if you already have built it!

I had to use shims to get a tighter mesh. With the loose mesh I had in my diffs with no shims, I would not be surprised if the gears would strip quite easily.

ALL crown gears and pinions need to be shimmed in order to have perfect mesh, which is crucial for durability. I am a bit surprised that Xray chose not to include this...

Tamiya makes some very nice shim kits in 0,1 and 0,2 and 0,3mm thicknes (TAMIYA part number 53588 for the 10mm set). I bought a bunch of shim sets in various sizes some years a go, since there is always something that need to be shimmed properly

Sorry onekiwi,, but I don't like.



Why.....

....cause it's sitting on your work bench and not mine.



All the best at your first test day.

Onekiwi, do you fancy showing us a few close up pics of your wiring/ what space you've got in there? I notice you've mounted your receiver on the rhs of the car...

Hey the guys/girls who have already received their buggy kits, has the instruction manual been updated or did you receive a setup guide showing which screws to use for the different flex of the chassis settings?

Just keen to know.

My manual is not updated, so its a bit confusing to know which screws to remove for the different settings.
I havent checked my XB9 manual, but i guess you could adopt the settings there?

Edit: If you go to the above linked XB4 presentation and scroll down to the presentation of the multiflex chassis, there are three images showing the three different settings (animation).

No screws = soft
Screws along the centerline = medium
Screws along the centerline + outside in both ends = hard

There is a guide in the manual and on the setup sheet that follows

Wiring, yeah I think there is tons of room as I came and still have a durango 410.
I have a hobbywing V2.1 which is one of the biggest escs and there is no probs with room, only thing is I might file off the screw hole/cable holder thats on the outside of the sidepod, that way I can rotate the esc 90░ and solder the wires downwards

With the short distance to the motor from the esc I think you could use 14AWG for more flexibility and 12AWG to the batteries as either the + or - will be quite long
My motor wires went over the upper brace but Ill sort out a little better install at a later point.

Pics Ill look at getting a little later on today

heres one:

i see that a lot of these build-ups are missing motor fans like xray shows on their web site. is there are reason to not run a fan in a 4wd buggy?

The esc's look better withour the fans and it makes it look like there is more room.
Always run a fan with 4wd
