Thrust
The thrust principle of flight is the mechanical force that moves
an aircraft through the air. The motion must be created in some
way by engines, propellers, rockets, muscles (in the case of
birds that can fly), or whatever propulsion system is employed.
If thrust is greater than drag, the aircraft will increase in speed.
Thrust must equal weight and overcome drag.
Figure 1-3 illustrates the four principles or forces of flight.

Flight Maneuvers: Aircraft
Movement with Stick Mapping
Most UAVs are controlled with a standard six-channel (mini-
mum) remote control just like those that model airplanes have
used for many years. The remotes have two main joysticks that
move both forward and backward as well as left to right. You will
also see some combination of switches, knobs, and sliders,
depending on your model. Each of these input mechanisms
occupies one channel of your radio.
The two main sticks are the most important controllers and
occupy four channels total, one for each axis the stick can
travel. Outside of the main sticks, we will always need at least
