Pic of Speedpassion Slotless sensored motor
 

I figured I'll post some pics of a Speedpassion 2pole Slotless sensored motor. It's listed as 2500kv and comes with 12awg wires soldered on. It's basically a 540L motor with a sensor port, making it be bit longer. Looks like a Delta wind. I haven't used it, but I don't expect it to be any different from a regular 540L motor.
Magnet is 19mm X 31.75mm(35.79mm w/endcaps). Rotor is wrapped in carbon something. Big blobs of blue stuff was used for balancing. Rotor shaft is 5mm throughout.
