So my I clearly limited understanding of phase resistance is still a challenge.
I measured the resistance between the phases of a couple of these: NEEBRC 3542 920KV Outrunner Brushless Motor with Hobbywing 50A V2 ESC for RC FPV Fixed Wing Glide Drone Aircraft Warbirds
And got similar values on my multi-meter as I do on the Sunnysky. I clearly need a better meter for this as 200 ohms is the lowest setting it has.
Thinking I had learned from your post @dekutree64 I set what I thought were conservative values, limiting motor voltage to 0.25v.
On applying power the little MKS DUAL FOC V3.3 instantly flared like a match. I think I am getting addicted to that smell… 
I could not find any data on the real phase/motor resistance nor get confirmation of the number of poles. I have not yet disassembled one to look but am tempted to. It clearly has 12 stators and I am assuming 14 poles as that seems to be a common configuration on these types of motors.
These motors each come with 50A ESCs and I suspect they simply need more power than what this hardware can deliver.
Should I expect to be able to drive these at all with this little driver board with appropriate settings or am I literally expecting it to work beyond what it is designed to do?
