@Alex-Kushleyev 1.3.2 seemed to have got the job done. I will let you know if I run in to anymore issues while tuning the esc.

@Chase-Riley , great!

Now, the tools in latest dev branch have some improvements including plotting. Can you please try one more thing:
- use voxl-esc dev branch
- replace the following file from v1.3.2, which will allow you to use the old uart bridge interface : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/voxl_serial.py replace with https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/v1.3.2/voxl-esc-tools/voxl_serial.py
this will be easier to support

@Chase-Riley , absolutely no problem regarding sharing the motor / propeller specs.

Alright, i have just posted initial instructions for low-kv motor tuning here : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/dev/voxl-esc-tools/doc/low_kv_motor_tuning.md . There is also a firmware update version 39 RC11 that you will need to install (this is part of the tuning instructions).

Please go ahead and work through the procedure. It is quite detailed and goes beyond what is needed just for low-kv motors, but it represents pretty rigorous initial test that should be performed to ensure your motor will operate smoothly under various conditions.

The parameter file ../voxl-esc-params/low_kv/mn4006_m0134_6_low_kv.xml should be a good start for your application, but do follow the instructions to check / update the params as instructed.

Please let me know if you run into any issue or need clarification.

The main idea behind testing new motor/prop combination is to start with "easy" tests and gradually ramp up the scope of test as you look at the data and become confident that it is working well. I would definitely avoid doing things like plugging in a new motor and prop and just going to 100% power command without a ramp :).

I will be improving / updating the instructions in the coming days and will keep you posted about any major updates.
