Thanks in advance
Thanks in advance
FYI, check this and make sure you're not having the same issue. Scroll almost to the bottom, friend had the same issue and was fixed after rechecking his build of the steering rack.

I've previously raced a Caster S10B and found it to be a good car. However...
...having built and driven the Xray all I can say is WOW!
The car builds beautifully, with no messing about fixing production errors or wrestling with ill fitting parts. I built it entirely as box standard apart from removing the daft plastic insert that sits under the rear gearbox. (I did have to modify the suspension hangers a little to get then to sit down snug on the chassis).
Driving it is interesting. With the Caster I was constantly concentrating on keeping the car under control. With the Xray you find yourself not having to do that. You just drive it. It goes where you want and it behaves entirely predictably. The effect of this is that you end up concentrating on your driving which is different from concentrating on driving the car.
You can push and push - finding better lines and getting a fantastic rhythm. Lap times come crashing down. At the start of my first meeting with the car I was turning 18 second laps consistently. By the end of the day I was into the 15's!
Astonishing piece of kit.

Another wee mod I have done (being a cheapskate Scotsman) is to cut a small strip of Coke can long enough to wrap around the CVD joints. This is then held in place by the existing plastic CVD covers. Eat your heart out Exotek!

This. I removed the mounting posts completely since I dont use them ( velcro ), gives me the option to put them back on if i ever go back to the 4wd body. We have more than a couple XB4's at our track, and its something different than the original and Finnisher bodies.
Also, if you are running an aluminum servo horn, you may have to run the inside hole, and trim the outer hole off, as it may hit the body.

Hi,
Would like to know what type of spurs everyone is running? Running 17.5 no timing, have been using associated 72 but have stripped out 2 in one meeting.
If this is the only option how does everyone bore out the center hole to make it a perfect fit. Every time I do it I always get it a little off center.
Thanks

I haven't even been able to find them anywhere. Anyone know of somewhere that has them in stock?
I stripped out an XRay spur and all I had in a pinch was Associated, so i used a body reamer ( Dynamite double bladed ) and did little bits at a time from each side of the spur. Worked out just fine for me doing it this way, what method did you use to open the hole?
