# simple example demonstrating how to control a Tello using your keyboard.
# For a more fully featured example see manual-control-pygame.py
#
# Use W, A, S, D for moving, E, Q for rotating and R, F for going up and down.
# When starting the script the Tello will takeoff, pressing ESC makes it land
#  and the script exit.
