Yes I observed some variations of Kv depending of the ESC
** Brand
** Timing
Also it happens that some ESC are not starting well if voltage is too low.
After starting-running some ESC could go down in voltage or PWM to some
low speed limit.
SLS ESC are very good to go low speed (FOC algorithms with a lot of DSP)
