Xray XB4 thread

Can someone tell me if the '14, & '15 use the same front and rear drive shafts and what the lengths are and what part numbers I should be looking at getting? I know the front on my '14 is 68mm, not sure about rears. I am not home to check and want to order new ones right now. I see a set for the '15 on ebay but wasn't sure if they are the same.

Looking at giving off-road a try.. there seem to be some good deals on '13/'14'/'15... How would an older '13 hold up compared to a newer version??? I'm not looking to have the hottest technology but if it's really worth the upgrade, i'd rather get the newer model...
any feedback helps... it will be run on an outside dirt/clay track... 180x85...
thanks

I'm expecting my new KIT XB4 and I'm coming from nitro 1:8th. I have no idea how to choose motor and ESC. I'm reading that motor's KV in relation to the battery has huge effect on runtime.
What do you guys recommend for motor in KV ? And what Pinion gear i may need? What adjustments to do for big tracks outdoor and what for indoor?
Also happent to have a reedy sonic motor size 550 & 5.5 turns / 3730KV. Can i use this one ?
Thanks in advanced.

Took the time out of my day to measure the different track widths using the new Xray 12mm hex wheels with the Xray 12mm wheel hexes.
All measurement are done on the '16 XB4 using:
Width using stock 14mm wheel hexes and Xray V2 14mm wheels:
Width using 12mm wheel hexes and Xray 12mm wheels:
Front:
Rear:
Bent
All measurement are done on the '16 XB4 using:
- 20mm ride height (placed on Hudy 20mm droop blocks)
- 3 degree toe-in in the rear
- 1 degree toe-out in the front
- Hinge pin inserts in the middle position front and rear.
- Measured on the rear of the rear wheels (no tires)
- Measured on the front of the front wheels (no tires)
Width using stock 14mm wheel hexes and Xray V2 14mm wheels:
- Front: 245mm
- Rear: 245mm
Width using 12mm wheel hexes and Xray 12mm wheels:
Front:
- #365354 -0.75mm = 242mm
- #365353 0mm = 243,5mm
- #365355 +0.75mm (1 stripe) = 245mm
- #365356 +1.5mm (2 stripe) = 246,5mm
- #365357 +2.25mm (3 stripe) = 248mm
- #365355 +3.00mm (4 stripe) = Not enough threads on axle to secure the wheel nut.
Rear:
- #365353 0mm = 243mm
- #365355 +0.75mm (1 stripe) = 245mm
- #365356 +1.5mm (2 stripe) = 247mm
- #365357 +2.25mm (3 stripe) = 249mm
- #365355 +3.00mm (4 stripe) = 251mm

Thanks for doing this, by the way. I measured my car with the Xray 12mm front wheels and with the TLR 22-4 wheels (I've been racing it since release so I have a TON of those wheels) and appears xray uses the same offset in their wheel as TLR does. Very good news for me. I probably don't have as nice of measuring equipment as you do, but someone else mentioned that the car was stock 245mm width with the TLR wheels and the +0.75 hex, I wanted to check that out for myself.
Here's my car too.

Meausurements will vary with ride height, toe-in, bump steer etc.

Thank you for your response, but the issue now is the motor size, rotor size and KV Selection. Too many parameters to choose
Savox says KV for their motor 6.5
http://www.savoxusa.com/Savox_6_5T_S...vblh365065.htm
Hobbywind Xerun 6.5T says KV 3650 - 5200 (???)
http://www.hobbypartz.com/07e-c-sd-6-5t-3650-blue.html
Turnigy Trackstar 6,5T IS 5150KV
http://hobbyking.com/hobbyking/store...or_5150KV.html
Reesy Sonic 6,5T is 540 size but no KV Rating.
What about size? 540 VS 550 ?
Poles?? i saw somewhere 3...
Rotor Size ? What about all that ?
Also what pinion gears i will need?

20 or 21 pinion will work fine for 6.5, just need to check temps and lower number of teeth in case it get too hot that's it.
Motor size is 540. 6.5 is powerful enough in most cases and you could add timing if you need more power.
Coming from 1/10th I was a bit lost regarding KV and gearing for 1/8th e-buggy, you should be lost as well regarding 1/10th motors and gearing but overall it is very simple, check your temp and adjust to taste.
If you plan to run more than 5mn runs, then go for a 20T.

Here's a setup you might want to try that I found on the xray website. I think Bentka said they are ending up with same diff weights front and rear so I may try this at my local(ish) clay track with 7K front and rear. Anyway, thought this might be interesting.

Honestly with this know issue this could be a major factor to push people to getting a yokomo unfortunately. Mine was perfect through the first race day but If this is going to be an issue I will not own this car for very long if I have to replace gears every weekend.

Fortunately the car runs fantastically, hands down more.corner speed than any other wheeler I've driven... I started with Bayers clay setup and found the oils and springs way to light... went back to stock springs and shock locations 1.6x2 hole 40wt 1.7x2 hole 35wt and it was excellent, the rest was Bayers setup...
