After fiddling with the timing, the controller set itself alight in exactly 5 seconds after switching it back for a 3'rd shakedown ride.

Yeah, that was pretty much the same way mine went, but after changing the pwm switching rate.

The ecrazyman 12 FET (48v 600w) controller was the base that I used for my HXT 80-100-130 powered bike. Upgrade the FETS, tracks and wires. I have it running well at 12s 100 amps and it barely gets warm.

The throttle response seems faster than the Turnigy (set to fast) was, although not instant It is quite acceptable.

Make sure you also buy a usb programming cable from keywin when you get the controller, you will need it for tweaking!

Thanks for the advice Burtie, I'm now one step closer. Do you have a feeling for the accuracy required for the relative positioning of the sensors with respect to each other. I assume that the phase angle of the 3 sensors as a unit can be tweaked as an offset in the software?
I'm wondering if hand tools will sufficient for the construction of the sensor holder or if milling the slots is what is really required.

Due to the high pole count (14) of these outrunners, the positioning and spacing of the halls relative to each other needs to be quite accurate.
1 mechanical degree = 7 Electrical degrees, small mechanical error = larger electrical error.

I constructed my external hall mounts using a mill and a precision rotary table. If you do not have access to these, you may find that glueing the sensors into the stator slots is your best bet, there is less scope for error (I am curently running my bike using internal hall sensors, and it works well).

There is no way to adjust the sensor timing in the software.
