The V7 absolute motorhead has 2 types of small wheels. Can they BOTH be removed? I managed to remove the one which has a long axle, one side of which is all visible in a channel. Now I need to clean the other type of wheels. The other type has no such side channel, and both ends of the axle are inserted into the plastic body. [/img]Do i remove the same way as the other type? I'm scared I'd break the plastic body.
