LOL, I couldn't imagine myself spending as much as you do on this R/C stuff... it goes to other projects I'm doing, such as my electric Toyota truck conversion, and the like... hehe.
Do you know of a controller that will do 12s A123 AAngel? I am thinking I would use a 1521/2Y as that would get me around 30,000rpm, or maybe a 1515/2Y, but that would rev to 42,000rpm, a lot of power!
