You assume that running a motor is just a case of the right settings on the ESC. That is not entirely true. It could very well be that the CC firmware is not compatible with running this drive. Neu has made changes in the stator design and so even if this setup was fine in the past, that may not be the case now.
Please try the budget controller and see how that runs.
The stator design was done years ago and I doubt it has any influence here.
First try changing the PWM to the highest available setting.
