Yes, Derek is right, Shumacher is a RC car with viscous coupling.
Silicon oil is used on RC cars in couplings and shock absorbers. Its
graded from 100 to 10000 in viscosity. It comes in so small bottles that
filling a coupling to a syncro... well,I think with the right viscocity
it will probably work. Scania trucks also use silicon oil in the fan to
the engine. If I had a coupling to try on, why not? Could save some
bucks.
