DJI designed the mini 5 to weigh 249 grams. How DJI thought they could keep such a tight tolerance at the factory puzzles me BUT YES the Mini 5 can weigh 249-252 grams. Drones over the 250 limit will be subject to even more future regulation, and tho it hasnt happened yet, Drones that are heavier than 250 grams will in the future require you to have a 107 certificate, or fly only at the FRIA. As the sky's fill with Drones from everyone from Target to the local Government, Your free airspace will be shrinking dramatically. If you want a Mini 5 , GET IT. but be aware that you could face future rule changes.
Honestly Buying DJI in the U.S. Now is going to be a gamble. DJI makes a great Drone but if you live in the U.S. My advice is..Don't crash it unless you know how to fix it!
