Is there any OEM part or anything that's a twistable handgrip, a la motorcycle throttle, but with a pot embedded in it? I've used one in the grocery store - one of those electric carts, when I had a stubbed toe that hurt to walk on - forward for forward, back for reverse, and proportional, i.e., not just a switch?
Or will I have to design one?
Oh - wait - I'll just go look for patents; but if anyone has a burning desire to tell me about a particular part or so, I wouldn't turn away any suggestions.
Thanks, Rich
