Circle will orbit a point located CIRCLE_RADIUS centimeters in front of the vehicle with the nose of the
vehicle pointed at the center. The pilot can control the yaw of the copter, the autopilot will not retake
control of the yaw until circle mode is re-engaged.
The pilot does not have any control over the roll and pitch but can change the altitude with the throttle
stick as in AltHold or Loiter mode. The copter cannot land in this mode. Radius of the circle can be set
by modifying the parameter CIRCLE_RADIUS.
The speed of the vehicle (in deg/second) can be modified by changing the CIRCLE_RATE parameter
Circling will not stop until another mode is selected
Centre of circle is defined by GPS coordination and cannot be changed
7. Guided Mode
This mode requires communication between Ground Control Station (such as Mission Planner) and
flight controller. In the Mission Planner Flight Data screen map, try right-clicking on a nearby spot and
select “Fly to Here”. You will be asked for a guided mode altitude. Enter an above home altitude in
meters.
8. Follow Me Mode
You will need a laptop (or a phone/tablet) with an integrated GPS available to the GCS. Once the flight
controller is connected to the GCS, the GCS will read the GPS data from your device and send it to your
Copter as “fly to here” commands every two seconds. Such that the vehicle will follow the pilot when he
is walking around.
This mode may requires additional device.
9. Auto Mode
In Auto mode the copter will follow a pre-programmed mission script stored in the Mission Planner,
which is made up of navigation commands (i.e. waypoints) and “do” commands (i.e. commands that do
not affect the location of the copter including triggering a camera shutter).
An independent chapter will further explain this mode.
10. Poshold Mode
Poshold Mode is the combination of GPS loitering mode and AltHold mode. GPS lock should be done
before takeoff, to avoid GPS glitch during the flight. The control and reaction is similar to AltHold mode:
When the pilot releases the sticks the copter will lean back to bring the vehicle to a stop. When no
control input, it performs same with Loiter mode.
The maximum brake-angle can be set with the PHLD_BRAKE_ANGLE parameter (i.e. 3000 = the vehicle
will lean back up to 30degrees)
The speed the vehicle rotates back to the maximum angle can be set with the PHLD_BRAKE_RATE
parameter (i.e. 8 = rotates back at 8 degrees per second)
11. LAND Mode
LAND Mode attempts to bring the copter straight down. The flight controller uses barometer for
determining altitude. If the vehicle has GPS lock the landing controller will attempt to control it’s
horizontal position but the pilot can adjust the target horizontal position just as in Loiter mode.
12. Acro Mode
Acro mode (Rate mode) uses the RC sticks to control the angular velocity of the copter. The throttle is
completely manual with no compensation for tilt angle of the vehicle. Not recommended for new
pilots.
