Welcome to the XRAY X12'17 Thread & Wikipost! Here you will find some useful info, tips and tricks as well as setups that are used by several team drivers. Many of us run the X12'17 on high bite carpet and with most US tracks going to the new black CRC carpet, most setups from here out will be developed for those high bite conditions.

Tips & Tricks:
Some racers notice slop developed in the front end over time. One method to reduce/remove this, as pointed out by some of our friends in Europe is to score the inside of the plastic front pivot ball (where the kingpin goes through) with a sharp xacto blade. Usually 4 scores at 12, 3, 6 and 9 will do. Alternative options can be found listed below.

As with any 1/12 pan car, a smooth operating suspension is critical to performance. It is recommended to polish your kingpins & hinge pins using a dremel or a drill and some sort of polish (IE Gravity polish or Mothers Aluminum polish will work). If you find that your suspension has a bind, you may look at using a reamer or drillbit to make sure the holes are clear of any flashing or debris. The only place this may happen is at the upper hingepin, which is 2mm dia.

For stock racing we usually find ourselves looking for a little more steering. One trick that some of the stock drivers have done that seems to help is lowering the graphite plate that the servo & shock mount to. To do this, you will need the 17mm standoffs from VBC and the servo mounts from the 2015 or earlier X12. Be careful that the servo mounts do not sit crooked on the plate when attaching it; a 0.2-0.5mm shim will help ensure it sits perfect on the graphite plate. Part numbers can be found below.

Option Parts to consider:
XRA371220 X12 Foam Bumper
XRA372012 Composite Front Upper Arm Mount – Right – Graphite

XRA372022 Composite Front Upper Arm Mount – Left – Graphite

XRA372113 Composite Suspension Arm Front Lower – Right – Graphite

XRA373584 Side Spring C=0.6 - Silver (2)
XRA373586 Side Spring C=1.2 - Black (2)
XRA375010 Graphite Rear Axle Shaft - highly recommended
XRA378094 Shock Spring C=2.1 – Black

Lowered Graphite Plate:
B-02-VBC5005
XRA376255-O Alu Servo Mount - Orange (2)

Front end options:

I'm guessing yes. Need to make a real reason for people to upgrade or force one by making sure it's not backwards compatible

Should have some info from Xray very soon. Probably sometime next week, or earlier if we are lucky. I know they are working on it.

Even with that trick, it's no Xenon front end... Slop doesn't come only from the composite ball, and that composite ball is also supposed to let the kingpin slide more smoothly.

Ie: the motor shifting in a mild shunt no matter how tight you torque the screws down?

Yes the motor shifts/moves to easy after a small tap.

I switched to flanged Kyosho screws that use a 2.5mm driver and that was the end of my motor moving problem. ( I probably also hit less stuff as I drove the car more.) That said, I am excited to see they added a 3rd screw. Looking forward to getting one when the funds allow. Maybe January...

Side question: Will XRAY be offering an aluminum chassis? I seem to remember seeing a picture floating around somewhere...

Yes they do and a aluminum pod too.
The order numbers are 371108 and 371254 for the pod.
I'll post a couple photos after I build it. which is next were hopefully.

I had several meetings ruined with motors moving and then found out there was a replacement part that solved the issue (3.2mm slots on the old bulkhead replaced with 3mm slots) I got one and used it with several crashes (including a vicious take out on the first lap of the final that broke my rollover mast) the motor moved the tiniest amount if at all.

The thing I really dislike is the alu brace, I find the diff side nut undoes and it is a pain having to take the axle out to fix it at a club meeting where I already don't have enough time between heats.

Had that happen at the worlds mid run, jammed the diff and cost me a run.
Not a problem any more
