Intel® Falcon™ 8+ Drone - Topcon Edition: Basic flight principles

Redundancy:

For redundancy, the Intel® Falcon™ 8+ Drone - Topcon Edition has eight propellers. Four propellers turn clockwise, four turn counterclockwise as shown in the image. This eliminates the torque of the single propellers as much as possible. Nevertheless, the UAV has no inherent stability, and a control circuitry needs to constantly monitor and control the UAS to keep it stable.

Flight directions:

By varying the turn rate of the different propellers, there are four controllable directions along three axes on which the UAS can be controlled:

  • Roll axis: movement to the left or right. For example when rolling to the right, the propellers of the left motor rail are turning faster than the propellers on the right motor rail.
  • Pitch axis: movement forwards or backwards. For example, to fly forward, the four back propellers turn faster than the four front propellers. The UAS takes a certain angle along the pitch axis and flies forward.
  • Yaw axis: adjust the heading of the UAS. When yawing to the left (clockwise), all left turning propellers turn faster than the right turning propellers.
  • Thrust: ascend or descend along the yaw axis. All propellers turn faster or slower to ascend or to descend.

Thrust:

  • Up = Ascend 
  • Down = Descend

Yaw:

  • Left = Turn heading left
  • Right = Turn heading right

Pitch:

  • Up = Fly forward
  • Down = Fly backward

Roll:

  • Left = Fly left
  • Right = Fly right

Extra Yaw:

The upper part of the right control stick can be turned, which controls the yaw movement of the UAS. This special function makes controlling the UAS very intuitive as all controls to move the UAS in the horizontal pane are accessible with one single hand.
