f) Pitch
Pitch denotes the movement around the cross axis
which can be compared to the nodding of a head.
Through this, the QuadroCopter gains flight speed
forwards or backwards or decelerates.
Point (1) indicates „forwards".
g) Roll
Roll denotes the movement around the centre line
which can be compared to the sideways rolling of
a ball (or the sideways crawl of a crab). In this way,
through lifting one side the QuadroCopter moves
independent of its forward direction to the side.
Point (1) indicates „forwards".
