12.5.3 Starting a Waypoint Session
12.5.3.1 Throttle Position
When flying waypoints, if a problem related to GPS or compass is detected, the MicroVector will at least
temporarily switch to 2D With Hold flight mode. So, it’s strongly recommended that your throttle be left in an
appropriate “Cruise” position while the Waypoint session is executing.
For multirotors, since rapid descent could occur if the throttle is below the midpoint when not in Waypoint
mode, it is recommended to keep the throttle at its midpoint during waypoint navigation.
If, during waypoint navigation, your throttle position is moved to below about 33% up, Waypoint mode will
pause, returning control to the pilot and placing the MicroVector in Loiter Mode temporarily.
For fixed wing, if the throttle position is reduced to below about 15% up, the waypoint navigation will
continue but, for safety, the MicroVector will command the throttle to be at its “throttle off” position. This
should normally stop the propeller from spinning. So, the model will ultimately crash land unless throttle
is increased! The message “Safety check fail, throtle off” will appear in the OSD notification area if this
event occurs.
12.5.3.2 Initiating Waypoint Mode
When your model is flying at a safe altitude, with the throttle stick moved to at least 15% up, move the
Mode Switch to the “Waypoint” position to begin waypoint navigation.
Note that if “Permit Low Altitude Waypoints” was NOT checked when waypoints were configured, the
following may cause the throttle to shut off during Waypoint mode:
 Waypoint mode is triggered below about 32 feet (10 meters).
 During waypoint navigation, the plane descends below about 32 feet (10 meters).
Also, note that if your airspeed (or ground speed, if the pitot tube is not in use) is less than 3MPH/5KPH
during Waypoint mode, the throttle will shut off.
The message “Safety check fail,throtle off” will appear in the OSD notification area if any of these conditions
is detected.
When your multirotor is armed and at a safe altitude, and the throttle is moved to above 33% up, moving
the Mode Switch to the “Waypoint” position will trigger waypoint navigation. If a ground takeoff is desired,
make sure your first navigational command is the “Takeoff” command. Then arm the multirotor, switch to
Waypoint Mode, and move the throttle at least 33% up to start the waypoint sequence.
When Waypoint mode is triggered, the message “Waypoint navigation started” will appear briefly in the OSD
notification area.
12.5.4 Pausing and Aborting Waypoint Navigation
12.5.4.1 Pausing Waypoint Navigation
Waypoint navigation will pause if one of the following events occurs:
 The MicroVector detects a problem with the GPS or compass. 2D with Hold flight mode will be entered, and
waypoint navigation will resume at the current command if the GPS issue quickly corrects itself (see
section 12.4.4.1 – ‘GPS Fix Requirements’).
