Evening Tim sounds like the little white thing is just the servo horn .
may be there is no servo saver on this model its a very old design car this being a re release of a classic.
the steering issue could just be like Andy said down to a cheep servo, or just down to the wire push rods bending. it might be somthing you will have to live with
These cars where never designed to run like the newer cars or take the Hammer that we give them if you have seen club racing you will get an idea of the treatment we put them through
at pressent we are still racing indoors on the saturaday night at a local sports hall, just out side of Eastwood, but the club have just held a outdoor meeting last sunday in all that rain
