I didn't have any luck with the older type that had the screws on the bottom, but the one that I have now which has the cooling fins seems to be a lot more reliable.
I have no idea which mosfets the old one had because I read through fechters reverse engineering of the controllers and figured that for the amount of time that it would take me to pull mine apart, find the problem and change the mosfets I could just go to work, earn the money and buy a new one..... Sometimes I'm lazy.... sometimes I'm even lazier.

Those phase wires even seem a little small.... I'm assuming those bits would need upgrading too.... yes?

Going by what you said, the motor has the potential to put out 10kW.
Just wondering how you came to that conclusion....was it though physical testing or through calculation?
Are these controllers possibley more robust than the Crystalyte units? or am I better off to stick with the Crystalyte?
Back to the subject of heating..... what kind of current can those phase wires handle?? Do you use the RMS rule or something to calculate their capacity?
Purely out of naivety and possibly stupidity..... (motor and battery capabilities aside) what would happen if I tried to run 2 controllers in to one motor. Is it possible?
If the hall sensors are delivering the same signal to each controller, would this mean that the output from the controllers would be in phase, thus doubling the power that the motor receives? or would there be some sort of issue with back emf or something??
