User Manual

Flying a drone autonomously with FieldAgent is extremely
easy, but like driving a car, there is a training process that
should be completed before you can fly safely and
comfortably. This document will set you up for success,
regardless of your current skill level.
Advice: Set aside 1 day to become comfortable using your system.
