| Can we have some more information on which 1/8th and 1/10th scale cars you are refering to? Do you mean to interchange a body from 1 1/10th scale car with a 1/8th?
Normally 1/8th is used for larger ic powered cars and 1/10 for the small eletric powered off-road buggies.
i.e. a 1/8 scale model is 8 times smaller than the size of it's real life (1/1 scale) counterpart.
