Xray XB4 thread

Can someone tell me what size drivers I will need to
Work on the xb4? I have everything for tekno 8th scale and have no idea what I will need for the xray 10th scale.
Also still need a pinion size to use with 8.5 motor. Looks like 20-21 is good start for my 6.5 motor tho?

Schelle just restocked all of their xray pistons as well.

Fyi you can't use any piston they won't fit the shafts. Xray pistons are thinner than others which limits you to use only xray specific pistons unless you go to a different brand shock shaft. I've used associated shock shafts before which opens up your options for pistons. There are probably losi and kyosho shafts that will fit also. As long as the shaft is close in length and same diameter you can make them work with spacers or unscrewing the shock ends slightly.

i laugh when i see your posts, always something broken, always bagging out some thing on it or other. then you're happy to keep driving them, lol.
re: shocks - the Avid pistons are great, make a difference you can actually feel, and cost - wait for it - $16, the rest of the shocks are all good.
I ran the 14 on high grip carpet with a 6.5 then a 4.5 turn for over a year, so high speed rolls and crashes were a fact, yet my total breakages were 5 arms in total, 1 gearbox case, 1 cracked front tower, didnt even bend a hinge pin.

Xray is a metric kit so 1.5mm 2.0mm 2.5mm and 21-24t would be in the ball park for 8.5t. your better off running the 6.5t motor with a 20t pinion and protecting you motor from over heating, i run 6.5t motor on a medium size track and i can easily run 15 minutes and the motor comes of barely warm but still has tons of power, yet to achieve the same result with an 8.5t motor you would have to gear it a lot higher and risk cooking your motor.

I'm recently having issues with the pinion gear in the diff stripping out. Looks like only half the gear is making contact. Can u put shims behind the driveshaft and bearing. IM using the plastic gear now but waiting on local hs to get the back ordered metal gear. I'm guessing this must be happening to others as well

Ive read a few posts on the last page talking about the steel gear wearing out even faster than the composite gear,should i stick with the composite then? is anyone else having to shim like this?

If you take the extra 2-3 minutes to shim the diffs properly during the build, I don't believe you will have any issues.

I only have 40 runs on my car but I haven't seen any wear yet. I have only run the steel pinion but have run the gear(steel) and ball diffs(composite) without issue.
If you take the extra 2-3 minutes to shim the diffs properly during the build, I don't believe you will have any issues.
