Well put Brian, I could not have said it better myself. The cheaper motors also seem to prefer lower current draws (lower kv models). Case in point, a feigao 9l on 3s and a 15l on 5s. I have tried both in my 2wd emaxx, both geared for the same speed. The 15l does not get much more than warm, but the 9l runs hot, and requires good batteries to perform.
