One of them is Ian Hooper's. He's very accessible, and is very friendly about answering questions.

Ian's Controller Information
He is running his controller with current and temperature limiting, etc... with the parts I listed. He has a worst case scenario motor setup for a controller. It's an 11 inch WarP (I think) with no transmission (direct drive!). He blew up a 144v 500amp Curtis, so built his own to handle it. It also uses Lithium Iron Phosphate batteries I think.
