That was tempting fate wasn't it, rear diff screw snapped in half yesterday, what a bu**er!, not to mention losing the cross pin on the rear centre drive shaft twice! 3 races with front wheel drive only after only a few laps truely sucked....
I'd applied thread lock on all the grub screws and put flats on the drive shaft cross pins but hadn't bothered putting a flat on the centre shaft cross pins. I shall now remedy that minor issue and I'm also going to file/dremel a small semi circle at 90 degrees to each cross pin hole. I don't seem to be able to get a hex drive squarely onto the grub screws so I'm thinking they may not be going as tight as they could. With a little easier access to them I should be able to get a good solid drive on them and tighten them down till they squeak!
