I would not be surprised at a high current draw. When I was at secondary school
I remember guys rewinding the motors with about 8 turns of 16 gauge wire, and
then encasing it all in epoxy so it did not fly apart with centrifugal force. I
do not know how long the brushes lasted, but I could well believe some of the
figures quoted in the original request, although they would be taken under ideal
conditions ( wires fixed to car on rolling test bed) and would be reduced
somewhat by the wiring to the hand controls. I would still work on the basis of
several amps per track.
