I have a 120a Hobbywing SCT and 2250kv motor I'm about to drop into my EB48. (God-willing UPS will deliver it tomorrow). I'll be sure to report back to this thread and give my .02 on it. So far I can say this with certainty:

Pros:

Sensored
Terrific Price
Tuning box was included in the combo
USB cable for updating tuning box firmware included
Smallish footprint

Cons:

Prewired motor with bullets
Prewired ESC

The rest is yet to be determined.
