Can't find good parameters for FOC detection

Hello everyone,

I'm currently working on a 4012 480KV from T motor, power in 22.2V with a 15*8 propeller. 

For now I use BLDC but results are not good so I wanted to use the FOC command mode. I make the motor pass the detection but once I write new values and try with Duty cycle input most of the time the motor don't follow the command or have difficulties which I believe come from my parameters for the test.

How can I found the value of the time constant?

Is there anyway to know before end current, W and duty cycle values to put to perform the test or should, as specified in the help window try to find by luck kind of the good parameter ?

Thank for your time.
