I've been running the LT-200A sensored ESC in my CRT.5. I ran around 6-8 packs with an LRP-X11 3.5T motor. Was pretty quick and smooth. Since I have some more movement in my right arm now, I soldered up the new Hacker motor(6000KV) that I recently got. I like it alot better and it's stays cold. The LRP got to 149F after the pack dumped and the ESC at 119F or so. I can probably gear higher for dragracing, but it's pretty quick to bash with right now. I busted up one of my foam tires in the vid.
