Hi.

I would like to calibrate ESCs with the bolt flight controller.
I have understood that I should somehow initiate a calibration command from the flight controller to the ESC. Then ESC will register maximum thrust from the controller (= maximum PWM value from bolt). Is there any way to do this kind of calibration with bolt?

My setup is similar to this post: viewtopic.php?f=3&t=4474 but little bit smaller scale. I am using T motor Air 2216 880KW motor with Air 20A esc. https://store-en.tmotor.com/goods.php?id=727
In my setup ESC power is directly connected to the battery and only the motor signal wire (white) is connected to the ESCs.
Does that limit possible calibration options? I have BigQuad deck available if that can help with the ESC calibration.

Thanks in advance!

I'm not so sure what firmware Air 20A is running. It says on the page it supports up to 500Hz which I guess is servo signal rate. You can use the motorPowerSet parameter to manually control the output servo signal. Check this post to get some ideas.

Hi Tobias,

Thanks for the comment, I got the esc calibration started with motorPowerSet according your detailed comment here.
