For the FET selection, they must have decided that it wasn't worth the extra $2 in parts to use real FETs that would have kept 75% of the heat out off the controller. And they ran d-packs sinked to the board, which is fine for things used only for bursts, and keeps manufactureing costs down to a minimum, but very poor for any continous power application.
The stator shape looks like the favored ease of winding over function. It also appears very small, and I suspect it would easily saturate, and overheat if you tried to run real power into it.
I'm certian you could simply run extend the phase wires and hall leads to run external, mount and external controller and make it run. However, if you are going to invest your time into making something, I would start from a better platform like a 9C and go from there. 9C is like 10x a better design of a motor.

so, why do you think, that the wiring design is bad? Why would it "easily saturate"
To my opinion the wiring design is better than the 9C
I was wondering if you would be interesting in tinkering with a PL500W Bionx motor? I just blew the controller inside the motor today. see link viewtopic.php?f=2&t=15434
I would like to be able to mod it with an external controller for my set up and with a switch that can disconnect the battery for high speed downhill runs...in excess of 51 mph ...It would be fun to document this on the forum.
Please send me a PM if you are interested.
