I've found many speed controllers at the Tower Hobbies web page, but I am not sure what sort of input these controllers require. Has anyone ever interfaced the Handy board to a commercial speed controller? It looks like these units are designed to connect up with RC radio equipment.

Tom,
Try this company , They have single and dual Forward/Reverse
proportional speed controls for 4.8 - 140vdc at up to 220 amps and 3
hp. 500oz/in to 27 foot/pound packaged servos.
I have a catalog from this company, great stuff but the price range is
out of my hobby budget. It is for RC equiptment though.
Good Luck
