About the load that they put on the motor; they do give the Kv and the current it can 'handle'. i wouldn't be surprised if they used a fixed voltage for some odd reason. or they simple determine the max. load by the resistance/thickness of copper

Good point, Rene, centrifugal force can split magnet. And we seen number of motors with broken magnet not only from Feigao...
At 110C lots of things going bad, but at 130+C you will destroy magnet permanently, that what I was referring to. (I've got couple of those from my friends, saying they are weak... guess what they cannot even stick to refrigerator door :) )
About load, it is a dark territory with proprietary sign for RC, I guess.
For voltage measurment, keep in mind the correct is to measure voltage on the motor, not through connectors and FET's. Very difficult, but then do not expect exact matching with datasheets.
