thanks for that link... it would be nice if more people get in on diy'ing these because a lot of people want them but they are just too darn expensive. I have experience with rc cars/heli brushless motors and speed controllers... and neodymium magnets are easy to source, its just a matter of getting a good design down. It would be nice to see someone take apart a vortech and see how its designed.
