Diodes or capacitors?  The only place a diode is needed (if at all) is
reverse-biased across the leads.  Generally, all you want is three
capacitors.  One across the leads and one connected from each lead to
the can.   I've seen diodes connected across relays and motors in
other applications, but never RC cars.
