No they reduced the weight on the mini 2 so your good .Just out of interest I know it says 249 grams but I put mine on some kitchen scales and I only got 230 grams with 2 lights attached is my scales broke or is the drone under 249 grams that’s stated
Sorry I’ve got the mini 1 and still only getting 230gNo they reduced the weight on the mini 2 so your good .

Who knows and does it matter in any way at all?A gram is such a small amount of weight that could easily be a variance from unit to unit. 10 grams is less than 4/10ths of an ounce. Personally I find 250 grams as the cut-off weight for drones a bit ridiculous. Not only is it just over 1/2 pound, but the structure of the drone itself, with thin collapsible arms and relative hollow body provides a shock absorption factor should it hit a human or structure. I could see more of a concern if it were 1/2 pound of lead striking a human at the same same speed... which could be minimal. And don't most jurisdictions prohibit flight over people? So why this arbitrary hard/fast weight stratification that seems like all countries have moved to adopt?

As you know, being the Mavic Mini it should be just under 250 grams with no add-ons. Just the battery and CD card. Do you have the battery in? If yes, your scales might be off.Just out of interest I know it says 249 grams but I put mine on some kitchen scales and I only got 230 grams with 2 lights attached is my scales broke or is the drone under 249 grams that’s stated
I would recommend using another calibrated scale.As you know, being the Mavic Mini it should be just under 250 grams with no add-ons. Just the battery and CD card. Do you have the battery in? If yes, your scales might be off.

Thanks for the PDF. In some ways it shows the utter idocracy of this, that the world seems to have adopted. To take a snippet from the report:The totally arbitrary 250 gram cut-off weight was first cooked up by the FAA's Unmanned Aircraft Systems Registration Task Force, as presented in this November 21, 2105 Final Report.
Read it and weep. ?

I would never have picked "weight" alone as a threshold criteria for registration. A light weight foamy delta-wing model aircraft is never going to be as dangerous as a similarly heavy metal lawn dart or even a golf ball.what would be the ideal weight v registration criteria etc etc be?
What it's actually trying to say is that if everybody registers their names and addresses with their government and then they're forced to label their unique registration number onto every one of their own golf balls, footballs, tennis balls, ping pong balls etc, that will somehow magically prevent any of those balls from ever again flying into a crowd.I suppose it’s like comparing the chances of a ball going into a crowd, eg golf v football (soccer) v tennis ball v ping pong ball and so on.
The report calculated that an object shaped like a brick, but with the drag coefficient of a baseball, when dropped in freefall from a height of 500ft, would carry a kinetic energy of 80 joules, which has a 30% probability of being lethal when striking a person in the head, only if that object has a mass of 250 grams or more. [It also means the same scenario has a 70% probability of NOT being lethal, no?]I suppose we've avoided thousands of drone deaths by mere registration, no?
I get ya. Lots of numbers with virtually zero data. I'm going to sum up the FAA in relation to UAV's in three words:The report calculated that an object shaped like a brick, but with the drag coefficient of a baseball, when dropped in freefall from a height of 500ft, would carry a kinetic energy of 80 joules, which has a 30% probability of being lethal when striking a person in the head, only if that object has a mass of 250 grams or more. [It also means the same scenario has a 70% probability of NOT being lethal, no?]
They then decided "it is reasonable to estimate the probability of such a lethal event occurring" by further calculating the probability of such a "catastrophic event" occurring.
They assumed a mean time between failures of 100 hours[?], and assumed this 250 gram object shaped like a brick with a coefficient of drag of a baseball would be dropped from a height of 500 ft into a "relatively densely packed urban environment" of 10,000 people per square mile[!!].
The probability of killing someone therefor is:
"4.7x10-8, or less than 1 ground fatality for every 20,000,000 flight hours of an sUAS"
That's =0.000000047
The report further recognizes that the chances of anyone being killed by this hypothetical 250gram object are 1000 times less than the "current general aviation risk level of 5x10-5". [=0.00005]
Keep in mind this probability estimate is based on a 250 gram object. It's a safe bet that plenty of model aircraft and drones are flown weighing significantly more than 250 grams. One would therefor expect the probability of a fatality occurring as being proportionally greater, but apparently those have all been successfully eliminated by mandatory registration (as if).
I leave it up to you to look up total worldwide aviation fatalities, then divide that number by 1000...
