Why are drones 249 grams?
Back in 2015, the U.S. Federal Aviation Administration (FAA) created a sub-250-gram weight category for drones. 250 grams was the decided weight after a committee of aviation and drone experts were tasked by the FAA to decide the minimum weight of a drone that needed to be registered for recreational use.
Do drones under 250g need Laanc?
If you are flying in controlled airspace, you need to use LAANC to get authorization. You must have a visual observer colocated with you that can see the UAV if flying FPV.
