There is an audible 0.25 second delay between spinup of motor 1, then 2, etc. I have loaded the sentinel param XML file (I am using a custom aircraft, not the sentinel) to my ESC as a template and have only made one change; I set the motor KV to the value spec'd for my motors but I was getting this behavior prior to that change.
Any input would be greatly appreciated.
