A little super glue goes a long way. Just clamp the prop while drying and don't go overboard with the glue. In the mean time always have a spare set handy. Self repair gains confidence contrary to always purchasing DJI products.
These idiots deserve a hefty fine. They make it bad for regular everyday fliers like me and probably many others. The FAA uses the old "shotgun" effect to harm responsible fliers while not going after the true violaters!
Don't forget that even with these "color" zones the max altitudes are different. Lower closer to an airport, higher further away from the airport. Hope this helps.
