Waxy, the motor's not going to be at risk. (Unless the controller fails full on and you then declutch or shift to neutral, over-revving it to kingdom come - KA-BANG.)

I'd love for someone to come up with a workable, open source controller that a noob can build for less money than a commercially made version. ( Should we say "a used commercial" controller to be realistic? )

What will be the specs? Input voltage, current limit?

I'll bite: to the builder (you've got to build it!) goes a free Ecomodder sticker!
