I use the warrior controllers on a few vehicles. The BEC is rated for 12 cells(and ideally if you run more a UBEC should be considered), but I have run my warriors on up to 5s LiPo power (over 24 volts when peaked) with the controllers BEC and I haven't had any trouble. The micro controllers and warrior controller act the same when driving them, but the micro controllers have many more adjustable features via the programming cable, so you can tune it different ways. The Feigao motors have got to be the hands down price vs. performance kings of brushless. The Lehner basic and basicxl motors are a step up, and the "real" Lehner (19xx etc.) and Pletts are top of the line. The difference between the top of the line and the low cost motors (Feigao) is small, and most likely will not be noticed by the average user. The higher end motors may run a touch cooler due to slightly better efficiency, but as I said, most won't know the difference. If you are trying to set a speed record or for some other reason need to have every ounce of available power and efficiency without regard to cost, the top of the line Lehner motors are second to none. As far as the BK controllers and the Plett motors, I can't say how or if they work, as I have never tried them together.
