a $40 micro drone is training. It's a completely harmless toy, even less harmful than a soccer ball. This is not a $1000 hobby grade drone (for which you definitely should undergo training). A $40 drone typically has extremely weak brushed motors. You don't need training to operate a frisbee but you definitely need training to operate a discus. This comment is an example of how the general public does not know enough about the subject matter.
