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:
https://www.amainhobbies.com/xray-al...a303122/p12070

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)

Socket: Exotek has a full suite of parts, some bling, some not. Here's a list (all fit DE and CE, unless otherwise noted):

The parts you are mentioning were finished in production just last week.

Most of them if not all are on their way to RC America, but unless you are willing to pay a 30-40% extra for them to have it overnighted you will actually have to wait for the shipping and customs to take it's time.
Xray is based in Europe so all parts will normally be available in just a couple of days over here while it may take 2 weeks to reach RC America and then another few days to reach the dealers.

Nevertheless I've been patiently waiting and have resorted to ordering part from Austria. Only place I can find the parts I need immediately. Had to pay 21 Euros just for the shipping. That's how desperate I was.

From what I have been told, the demand is very high right now because this brand has exploded — and with reason. X-ray is doing great things in the industry. That's a good thing I suppose.

I'm more concerned about having replacement parts for maintenance. Its crazy that I cannot even get a spur gear.
You guys complaining seem to be all based in either the US or Australia.

All parts are in stock with Xray. And if some parts are out of stock it's normally just a matter of a few days before they will be in stock again.
But with the massive demand for the new XB2 and also XB4 I think the distributors over there has miscalculated and just not ordered enough to meet the first demand.
With the release of a new platform it's always difficult to judge how many of each parts you need.

Same thing has happened over here where distributors have gotten their stock emptied by some racers ordering a ton of spare parts to last them through the upcoming season. But as opposed to overseas they can get their stock replenished in just a couple of days. Overseas it can takes weeks for the parts to arrive.

You will see the situation going back to normal in just a short time as orders from Xray will be delivered overseas and distributors learn which parts are in high demand

If you continue to see the same parts out of stock over and over again with your national distributor then send them an email and let them know the parts are in demand.

Bent, What should I do for traction in the mid to exit of the corner? I have my shocks in the back.

There are several things you could try:
less caster
more rear toe
move hubs forward
more front droop
softer rear shock package
reduce anti squat
add weight to the rear

What track conditions and what tires are you using?

I have the hubs forward front and rear. 1on the anti squat. 28g in weight right under the tranny. The shocks are box stock and already seem a little soft. Indoor clay. Proline mc electron

try 0 anti squat... are you running the ball diff? also try the 0 insert for the caster if you are not.

Also, i was having some trouble with rear grip on exit when running PL primes, when I switched to AKA slicks I had way more traction. Have you tried different tires like clay chainlinks? I have found imo they have more rear grip the dirtwebs or electrons....

Ok. No I'm using the gear diff. I didnt like the ball diff. So less caster? Cant. Proline only. Proline is the best at our track so i don't think its that as much.

Guys, parts will get easier and easier to get as time goes on. This car is brand new. Heck, even B5m parts were hard to get when the car first came out. I've never had an issue getting parts for any of my Xray touring cars, I don't see the XB2 being any different.

Less caster for sure... also, you may want to give the ball diff another shot, assuming that its functioning properly.

When you guys move the shocks to the back are you making any other changes (oil, springs,positions)?

You realize you are effectively making the rear suspension stiffer, and taking away traction, right?

Is it one of those we don't know why it works, it just does, kind of things?

So why are ECS's being sold for the rear of the car? This makes no sense to me. I understand why they make a difference on the front of a 4WD but on the rear it just seems like a waste.

Bentka. Thanks for the response. Yes I'm from the U.S. I guess it just comes down to I'm very excited to put all the option parts on the car. The thought of making this beast "xb2" even better is nutty! In a area full of yokomo and b5m's I'm the only one with X-ray and consistently being chased!!!
