Yes, for some strange reason a difficult car to tame, nowt like the Opel which flies round with the right ballast.

I grind out excess plastic from the pod in front of the motor and glue a snug fit chunk of lead in there.

Then a strip each side of the pod on the chassis sills full length/width but clear of the body.

It goes well but can't catch the Opel.
