Since the
M3P communicates with its currently installed battery, I think that it would be all too easy for the drone to switch on its RID whenever 1 of its Plus batteries were installed.
I can't see this as anything but a detriment to the sales of the
M3P (or any other sub-250gm drone for that matter) for DJI, since 1 of its touted attributes is based on its extended flight times with the Plus batteries, & some (like myself) bought the
M3P based on its not needing to be registered, along with its extended flight times with the Plus battery.
Setting aside the inevitable point which will be raised by the statists here regarding strict adherence to the FAA Regs, in themselves having been, are & likely will perpetually be, an absolute mishmash of a convoluted mess rife with numerous gray areas if not contradictions, a few grams is realistically no more a danger than the difference between those who fly their drones recreationally vs those who fly them in even the slightest (by FAA definition) interpretation of commercial operation.
"Hey, gal, can you take a pic of me & my friend on the beach together?" FAA says, fine, no problemo.
"Hey, gal, can you take a pic of me & my friend on the beach together, & I'll buy you a beer." FAA has a cow if you haven't jumped through their hoops, paid them a fee, marked your drone exterior, & chain yourself to The System.
It comes down to the concept of "profit"... if a drone pilot were to gain anything, the FAA (i.e., gov't) wants a piece of it, & ofc, control of it.
My impression of DJI is that it's sold-out to the Draconian FAA (gov't) by foisting the most recent RID activation couched within the number of other variably valuable upgrades, & that being evident by not allowing that ability to be switched off or otherwise uninstalled or reverted to a prior version.
Really, though, I shouldn't be at all surprised, with China being the literal epitome of State/gov't Control.
