Yes it's a TSR motor. New 1.1 "the one" is what it's called. I think that's how it goes. Awesome motors really fast. They don't fade much. Only down side is the rotors are strong enough to pick up small screws off of the racing surface and it ruins them quickly. If your in off road an outerwears zip tied around it keeps it running for a long time. Onroad as well but you would want a much neater application than a zip tie around it.
