Did you happen to have worked on it or crash it before it stripped?

Several things could cause it to happen like the slipper being set too tight, gear mesh set too tight or too loose and the motor shifting causing the mesh to be mis-aligned.

i didnt work on it i have only run it like 5 times i have no idea about the slipper or anything

is it worht getting one of those really pricey ones or will a £4 do

Just replacing the spur without knowing what caused the problem may only result in a repeat performance.

I would just by the inexpensive stock spur or 2 (just in case) and go from there. That way if it does it again, you don't toast a pricey setup.

i do remember rolling it yesterday but it wasn't a bad roll

Probably shifted the motor during the roll and caused a bad mesh.

Replace the spur and reset the mesh and you should be good to go. Don't forget to use blue loctite on the motor mounting screws.

Your local hardware or hobby shop should have it.

Only use blue or medium strength.

Don't use red or high strength.
