Controlling the Aircraft

The virtual joysticks are used to control the aircraft’s orientation (yaw), forward/ backward movement (pitch), altitude (throttle), and left/right movement (roll). The function that each virtual joystick movement performs is determined by the choice of virtual joystick mode. Two modes (Mode 1 and Mode 2) are available. The default mode is Mode 2.

In each of the two modes the Tello hovers in place at a constant orientation when both virtual joysticks are centered. Pushing a virtual joystick away from the center position performs the functions show in the figure below.
