Hi All,
Just a wee interesting observation . .. My mini is brand new, I haven't had a chance to fly outdoors yet, so my initial flights have been confined to some test hovers and a few slow trips around the apartment.
I've controlled the mini with & without a phone attached, and it works just fine without .. VFR flight rules at it were ;-).
Anyway I noticed initially when the drone was on the deck with the motors spinning on flight idle, that there was subtle but noticable differences in the RPM of the various motors. A kick of the throttle & with the mini airborne, the drone would sit perfectly horizontally & obey the commands sent to it perfectly. Thus the motors would 'even' up at the higher flight rpms.
However after 15-20 mins of hovering, basic manoeuvering, landing and restarting, including powercycling etc. I've now noticed that when starting the drone into flight idle, all 4 motors are now running in perfect sync as it sits there idling, this is even after taking the battery out & swapping for a different one....
It seems that the mini does some running calibration of the motors after taking measurments in flight & on the ground, to even up the motor rpms once it's had a chance to sample how they perform.
It feels like the drone has 'self tuned'. Is this what it has indeed done?
Has the mini permanantly 'written' this calibration to memory, thus demonstrating why it seems to have 'remembered' the motor tunings, after i had taken the battery out & swapped it.
I'm assuming that is is normal behaviour for all DJI drones?
Has anyone else noticed this with their mini?
All good though :-)
