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

XRA372123 Composite Suspension Arm Front Lower – Left – Graphite
XRA372177
Spring 4.75 Coils 3.6x6x0.45mm, C=2.0 - Silver (Soft) (2)
XRA372178
Spring 4.05 Coils 3.6x6x0.45mm, C=2.5 - Black (Soft) (2)
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:
ASC4403 Kingpins, 1:12 Scale
ASC4622 Upper Arm Eyelets

ASC4626 Upper Arm Mounts/Steering Blocks
ASC4627 Front Axles
ASC8417 Pivot Balls

How's it going guys ? Quick question for anyone who wants to help .
I've decided to run 12scale and I'm looking for a pretty decent setup to start out . Anyone has a setup that's pretty good for a newbie like myself in this class ? I'm running the 17 plus fandom motors and also I'll like to run jaco tires but if there's a better tire I'll take than into consideration . Thanks again guys

Is this a good beginner kit? I've never raced before and I'm looking at getting into 13.5. We have a great indoor track nearby that is fully supported with xray,AE,Losi.

Thanks

In my opinion no. I say that as someone who has only started in the hobby this year. My 2016 car can be quick but it is far from easy to drive. Lots of off power steering, lots of steering around the middle but nothing but a serious push on power that is hard to manage. I've also had to replace a bunch of front end parts because of the slop that would make it wander all over the place. Can't wait to get a new car to be honest.

Hi, it depends on what class you are running and what surface you'll be on. If you run 17.5 on either gray or black CRC carpet, I have a good setup on Jaco blue front and green rear from Snowbirds last year. It is best on black carpet, but a little bit aggressive on gray carpet.

In all fairness, I think the 1/12 class in general is one of the more difficult classes for a beginner to start in. The basic design is simple, but there are so many small details that make a difference in how the car performs. Many of these things are easily overlooked by someone who is not familiar with racing. In my opinion, the Xray X12 platform is one of the most planted kits available. I don't think any other brand of 1/12 will really be easier for a beginner.

Well, that is tricky. BSR owns Jaco. Seems all the online shops I could think of to check for these compounds of Jaco tires are out of stock. Probably because most of the big races and a lot of clubs are now going to spec tires for 17.5. You could either go with the Blue/Green combo on BSR wheels from probably any popular online shop, or you could probably email BSR directly to order them on Jaco wheels. The BSR front wheel is slightly larger diameter than the Jaco front wheel, and of course both the front and rear wheels flex differently.

Hope that helps

Cannot help with setups as I run a different brand car, but on gray carpet Ulti X hard fronts and X med rears have been faster for almost all cars where I run.

This is going to depend on what chassis you are running (Carbon or aluminum), same for the rear axle, and also what electronics you use. I currently have 24 grams added to my car with the aluminum chassis and graphite axle to get just over 730g which is the minimum. I also have aluminum screws on the top side with steel on the bottom.

Edit: Tire diameter will also play a role in overall weight, so keep that in mind too. Smaller tires will of course weigh less.

Rear on the '17 is adjusted with shims under the axle bearing holders. The mid is adjusted with the shock, usually a combination of length and preload as dictated by handling preferences.
