On a brighter note, Castle have just released the new 2028 800kv sensored motor, so maybe the new 12S ESC that they were proposing years ago will soon follow. That would be the speed runners dream with a TP motor, and i may even have to try it out myself
I was looking at that motor too and emailed Castle. Got a reply saying it will be available in March. I heard from a little birdy the reason its not readily available now is because of a bankruptcy they recently settled on. Don't know if that's true or not..
