Xray XB2 Dirt Edition Instruction Manual
http://www.teamxray.com/xb2/2016/dow...w.pdf?update=2

BentKa: Carpet Edition 4 gear to 3 gear laydown conversion parts:
  • Gearbox #323014
  • Motorplate #324012
  • 36T idler gear #324236
  • Brace for waterfall #324031


Socket: Bodies Available:

Xray has two OEM bodies, the .75mm and the .50mm light weight:
light weight: https://www.amainhobbies.com/xray-xb...329701/p492942

OEM .75mm: https://www.amainhobbies.com/xray-0....329700/p477762

Also, I've fitted the yz2 body, both the light and regular fit fine, just make your own cut lines:

[i] J Concepts S2 Body [i]


Penguin Racing makes a high grip body that fits the DE and CE:

Socket: Wheel fitment:

According to some, you'll require different offset rear hexes to use B5M wheels. According to my Hudy setup board, B5M wheels are the same offset. I measured the overall width of the car with XB2 wheels, and then again with B5M wheels, same measurement.

On the front, B5M wheels were 1.5mm wider. Xray offers hexes to reduce width -.75 on each side, or you could spend 3-5 minutes and sand your OEM hexes down .75mm.

edit by dgrobe2112
here are the hubs for losi and AE

for AE Front 365354 -0.75
for Losi rear 365358 +3.00 (4 stripe)
for AE rear 365359 +3.75 (5 stripe)



Socket: Flex and the XB2:

Flex screws are as follows:

Plastic bulkhead between motor and waterfall. Can remove screw in chassis, or remove bulkhead altogether.

Waterfall has 4 screws, can remove the inner two or outer two. IIRC, removing the inner two provides more flex, and thus more bite.

Removing the battery brace. This gives a tremendous amount of flex on the middle of the car, and can sometimes be inconsistent. I do this for outdoor racing on low bite. I like the feel over the 4 gear in 17.5 racing, since the 4 gear will take some snap away off the corner.

Rear C block - has inner and outer screws. I haven't played with this, as it's a crucial pivot point of the car.

Medium arms and towers -> I don't believe the carpet car has the rear medium tower available, however the DE DOES have an optional hard part. I think the hard parts are more consistent, especially when it gets hot (90+ degrees F). However, the medium parts do NOT break unless you're severely talented. They also don't wear out.



Socket: Avid/Schelle Slipper mod:

Credit to WillS, Matt Trimmings, and myself for figuring this out months ago.

Parts you'll need:

B5M V2 3gear compatible top shaft.
TKO Special 5x13x5 bear OR 5x13x6 bearing Either can work. This replaces the spur side bearing on the top shaft.
5mm shims, same shims used in 1/8th scale clutch bells. Look for protek .1mm and .2mm kit.
Avid or Schelle b5m top shaft kit, with spur gears of your choosing. (DE can't handle a 69, the CE can)

Shimming: You'll need to install the bearing in the front portion of the removable piece for the shaft. Make sure the bearing is pushed all the way in. With the TKO bearing, you'll need to shim approximately 1.4mm on the front side of the top shaft. Roughly .3-.5mm with the other bearing. This is a "feel" and tolerance setting. I urge you to watch videos about setting clutch bell play in 1/8th scale to get an idea of what yield you want for end play. Too tight, it'll eat bearings.

Outside of trans case: Use Avid/Schelle top shaft spacer plus .2mm shim to offset slipper from motor plate perfectly. Install slipper as instructed, and use Avid/Schelle spring and XB2 slipper nut.

- NEW - Schelle now sells Xb2 Topshafts. They include a spacer, so no need for shims in gearbox, and comes with the smaller bearing. Both methods work.

Socket: Yokomo Differential or MIP pucks:

Credit to: WillS for figuring out pucks, and as well fitting the Losi 22 diff with the same mods.

Parts needed: Yokomo Bmax2 or YZ2 complete diff OR Mip PUCKS outdrives
Xb2 diff gear
Bmax2 V3 Worlds rear dog bones, or Bmax 2 pucks dog bones
You'll use XB2 axles, and will require no other mods for the axles or dog bones.
You'll need .2mm outdrive/diff shims. Shim approximately .5mm on each side of the diff, behind the bearings. The top portion of the transmission is what "sets" the diff in place, not the bottom half. A little play back and forth is fine, the stock diff has some play from the factory.

dgrobe2112: CE to DE conversion:
along with the parts needed.. you MUST have these following hardware, or it wont work

https://www.teamxray.com/xb2/2016/do...conversion.pdf

(3) XRAY 902340 M3x40 button head screws. these are the screws that mount the motor mount to the tranny
(4) XRAY 903322 M3x22 counter sunk screws. these are for the rear diff case, to mount to the chassis. i think i used some M3x18 and they worked ok.

Socket: Best method for setting up the XB2 ball diff:

The XB2 diff is stellar when setup correctly. The spring is too short and soft, allowing the diff to slip. You'll need to glue the rings to the outdrives with just a drop of CA, then add a 1mm shim between the spring and the outdrive. This preloads the spring and stops the diff from slipping so easily.

OR, you can run the AE diff spring, which is both slightly longer, and stiffer. The overwhelming issue is the stock spring allows the nut to bottom out on the outdrive before the diff is tight enough.

This shim:

This diff spring (don't need a shim, then.)

Default Antenna

Thanks for the pics of others layouts. Looks like I will need to play around with the layout a bit more. I have another question regarding the antenna wire. I think it has been covered in earlier posts but what can I do with the wire that doesn't involve a tube sticking out the body? Can I wrap it up in the wiring mesh?

Here's mine freshly painted :







The colors are a bit better here (the light blue on the nose doesn't show up much on the first pics)

this is what I used to http://s19.photobucket.com/user/plai...C4009.jpg.html

or you can heat your current antenna tube up and slowly bend it around a pill bottle. careful not to use to much heat

My antenna on the xb2 is way shorter than normal but it's due to the fact that on the previous car my antenna got snapped off and it cut off the antenna as well... I ended up just carefully trimming off the shield at about 30.5mm on the tip. Works fine but I'll admit if the thing didn't snap off I wouldn't have tried it.

Do the little cone washer that are in the kit count as 2mm of spacers?

So when we see setup sheets of 1mm they take the cone washer off and use 1mm?

So where is everyone adding weight to this buggy, and where are you buying/manufacturer of said weight?

Has anyone tried any aftermarket bodies? Thinking maybe a b5m body might fit half way descent.

Already been covered, they say no because of the clearance over the gear, Bentka used the yoke body for early prototypes but still not a good fit he stated...Another month or so and you will see more options, stock one looks good...
I'm curious about the dirt edition,if it will have a gear cover/ different body? Not every one races indoors, and will the body keep out small debris?
