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:
https://www.amainhobbies.com/yokomo-...z2-101/p417674


[i] J Concepts S2 Body [i]


Penguin Racing makes a high grip body that fits the DE and CE:
http://www.ebay.com/itm/X-Ray-Xb2-Hi...oAAOSw1S9WewHV



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.)

Functional Aftermarket parts: (Not just bling!)

Servo Horn: (The B5M sized horns are too short to get full throw)

I'm pretty excited for the new car. I raced my carpet edition last season the second it came out on both grey ozite carpet and indoor astro - the thing was just easy to drive and fast. I think with the new upgrades, it's gonna be even faster! I can't wait to get one in my hands.

All my comments here have been very pro-xray. However, I just realized the reason for these outdrive questions. I could live with $25 outdrive replacements. Just realized that was for 1!!!! Thats ridiculous.My RB6.6 is $7.00. I'm going to go home and check my xb4 as I will need 6 outdrives for a refresh.

Is this running stock or mod though ???

That's my only gripe with the b6 (have both xb2 and b6)...wish it came with 3mm drive pins so you can use the Hudy tool to replace often. Yes the parts are cheap but they'd last much longer if new pins could be replaced. Unless someone makes a 2.5mm pin tool.

$50 to replace 2 outdrives is reedonkulous. BUT they do last longer than the b6.

does anyone think the 4 gear laydown is perfect for using the carpet edition on clay with a mod motor?

im kinda thinking the 4 gear might be the ticket for the added rear grip, thoughts?

i bought the 16 again so i could have the medium plastics and the 4 gear incase. im going to buy the 3 gear as well though.

Any thoughts on what will be the best tranny layout for med-high grip clay?

After watching the rb 6.6 and the yz2ca with the 3 gear laydown i cant wait to try one in mine on high grip clay. You can see the corner speed that those cars have over the 4 gear.

Do you think the improved cornering will be worth it over the forward bite the 4 gear provides?

I kind of feel that to make a laydown car work with a mod motor, you need all the rear grip you can get, and I think the 4 gear provides that.

I just bought a brand new xb2 16 (again) because I wanted the medium plastics. On clay I use almost all medium plastics and it makes a huge difference. Provides some mechanical traction. Compared to other cars even the medium plastics are still firm so it's not like it's soft by any means, just right for new-high bite clay.

I run 6.5t motor and I'm a little reluctant to get the 3 gear. I'm sure it will be good I'm just not sure if better on clay. I'll have to test them both.

Also people should note that you either have to buy the 17 side guards or drill holes in the left side and swap the wire holders if you use them for the sensor wire or what have you.

Agreed on the medium plastics, but I did go hard on the steering blocks, and spindles, as well as rear camber link, tightened up the car a bit, and made the steering more direct due to less flex in the blocks themselves. Car feels more in tune with the track now. On another note, for those running xray springs on clay, what combo are you using, I find the 1 dot front a bit too hard.

with the right setup and tires, most likely 3 gear laydown. If the track gets dusty I would stick with stand up 3 gear as the rear will wash out too easily in a LCG configuration. Just my opinion, I have a lot of cars, constantly switching back and forth, but when the track gets dusty no matter the grip level I run a stand up config.

Can someone tell me what the track width is in mm with the stock wheels? Both front and rear. I've searched this thread but can't seem to find actual width measurements.

Cant hurt to give it a try. I've never had any rear traction issues with this car. I've even moved the shocks to the front of the arms and the car is even better. Just wanted a little more corner speed and hopefully the 3 gear is the answer.
