I've solved the cut-off It was just the batteries, Ive made a new pack and the car is fine

I've also cycled the pack that played up and they seem to be fine also (they hadnt been used for about a year)
The meshing doesnt sound that bad I suppose. The pinion is brand new and the spur seems to be near new. Its just that my TC is near silent (ta05ms) but this is louder but the pitch is larger so there will be more contact.
The car still seems a bit clunky in reverse though.
Cheers for the offer to look at the car, I will take you up on that

Unfortuantley it may have to be at the march meeting now as my wife is away and coming back at Midday on the Sunday so I cant really be in Bury racing my car

I might pop down first thing though to take a look and could bring the car with me
Whilst testing it indoors today it hit the childrens Chalkboard and obliterated it!! Luckily the wife was out so daddy managed to fix it and bribe the kiddies with a milky way...
