New to the 1/12th X-ray. What's a good starting setup for 17.5 stock. Tight black carpet track. Gearing, hop ups and so on. Thanks

this setup is pretty dialed for 17.5 on spec tires. The setup sheet lists the hopups.

Default Arrowmax spur gear

Do the 64p arrowmax spur gears fit the xray x12 ball diff?

Question..

I have the gear diff for the X1 and was wondering is it the same as the one for the X12 just change the right side hub and add what looks like a screw to hold the hub in place?

You have to get the RIGHT side hub. It is not the same as the left hub.

Does anyone know the weight difference between this and an older x12 such as a x12'15? I picked a '15 up used and it's a pig. Without the body it's over 730g. I am curious if it is heavy due to it being an older generation (5 models old) or if it's the electronics / the previous owner hid some tungsten in the shock lol.


It looks like the x12's are just heavy. I found the specs I was looking for '15 is 202g vs the '20 at 205g. So the new one is a bit heavier. They are both listed as 840g RTR.

I don't know what electronics you are using but my cars never reached the weight limit, always well below 730g. Maybe '15 was a little heavier due to massive rear bulkheads .... but not so much.
Even with aluminium chassis.

That motor is one of the heaviest on the market. What class are you running with a 21T 1s? That's crazy slow.

I think the big differences are the motor and the body... I always choose pro light. I don't know what are you using but at least a light is the way to go. Maybe also the rims... I run on Yoko rims. If you're running on carpet use the spool and shave some grams from that too. Some Ti screws here and there and you are the limit . It's the sum that makes the total.

The back of the car really needs to be light. Lightest motor and carbon axle are always the way to go. It's much better balanced.

New to 1/12 can someone please explain the comments section to me? Its seems like another language... also looks like some of the items are not marked. like battery position and toe and pod link... is the a standard that is known here?

  • 38.2mm front tyre diameter with superglue on the sidewall to prevent grip roll
  • An alternative front end fitted that was made by Mr Cheng, steering throw is measured on a setup station and usually expressed as degrees of inside wheel at maximum steering travel
  • Uses the Avid kingpin which is an alternative design that I think does away with the upper eyelet. Uses Green spooge grease as a damping agent (run damper tube oil on there to calm the car down)
  • A 0.5mm shim is under the front side link ball stud, this is supposed to add some rear steer to the car and make it rotate harder
  • The damper tubes have a 2mm shim under the outside, this makes them fractionally softer I believe, but happy to be corrected there.
