XRAY - Model racing cars

Here's the problem with the second one that broke, before I replace it - maybe this helps someone work out why it happened. On close inspection it has only sheared off about 2-3mm of the pin, the pin is still fixed firmly in the drive shaft...

wow, that's impressive. I've never seen anything like that on an Xray.

The only thing I have to add is that I find tightening the CVD set screw too hard causes binding in the CVD's motion (I'm guessing because it bends the pin).

Another race meeting last Friday, still getting to grips with running on carpet and dealing with new rubber which I'm told will take a few meetings to bed in anyway.

Very tail happy but lowered the car a wee bit and was advised to remove the back anti-roll bar and that has improved the driving experience a little more.

Trouble is, I still think that the Xray's weakest link are those bloody pins in the front drive shafts. After about three races they start working loose and screw up the steering!!

Why do they not add a small groove into the middle of the pin so that the grub screw has something to bed into and will prevent the pin ever sliding again? (so long as you use threadlock on the grub screw which I do each time).

At present I'm having to dismantle the front drive shafts after every race meeting and rebuild them - bloody pain.

Does anyone know of a manufacturer that produces the very same pins that the Xray uses in the front driveshaft, but which have a small groove machined out of them. I might even buy some standard ones and try to gently file a small groove myself.

I have spoken too, racers and model shops say this is a common problem amoung Xray owners!!

Come on Xray - you make such a lovely car, why let it down which such a stupid design with these pins...

BTW: did the 007 have the same drive shafts?
