This might be a noob question but here goes ...........
Having read Jimmy and Vickys report on the Euros, ive seen that although Neil Cragg is sponsored by Associated and therefore runs a B4, he races Yokomo in 4wd
How come he doesnt use the B44 ? How do these "team" drives work ?
I cant imagine that Lewis Hamilton would hop out of his McLaren and into a Williams etc
Cheers
