The same restrictions that apply to your <250g drone are the same for your >250g drone when you register it and fly recreationally. Meaning, nothing has changed; the weight of the drone (up to a certain large/heavy point) does not change the rules that U.S. recreational flyers must follow. Please continue to follow all applicable rules and if you are uncertain or forget those rules, you are welcome to refer back to the TRUST test to refresh your understanding.
The opposite is the most popular thinking: when your drone falls under a certain weight (250g) then you no longer need to follow certain restrictions. That would be incorrect as well. The bottom line is for the most part, the rules for recreational flyers (regardless the weight) are the same and you don't get less rules with a lightweight drone and you don't get more rules with a heavier drone.
Depending on your
Mini 4 drone battery weight and the recent updates to the sw, your RID may behave a bit differently than you expect. Please check it out and fly safe!
