I originally heard that the TC had different setups in it than the 07 spec, but if you download the instructions for both escs, they show the exact same setups--8 brushless punch modes, 6 initial brake modes, 6 drag brake modes and Li-po cut-off or ni-mh setting. They also both have the ability to show max. temp attained on the esc and a full current "launch mode"--hold down the brake for 5 seconds before start of race. Unless I am missing something I don't see a difference.
