wait to finish my hexapod made entirely out of aluminium and pop rivets :-)

David, Enjoy. our local(35 miles from here) "yard" only sell to the big
recyclers, NOT OPEN TO PUBLIC. they will buy all you 'pop' cans but not
re-sell to the single person.

BING BING BING....show him what wonderful prizes he has won :) I think I
will only need to move maby 2, 3 amps at max, but I still would like a
cushion to fall back on. I had been thinking of using some homemade
airplane Speed controllers. They work on PWM though, more complexity, plus
I don't have any that will do proportional reverse. Remeber I need to be
able to drive these puppys in CC, and CCW.

any idea of the part number? Don't need that many watts, prolly only 70
watts at max.
