5.10.2 Control Stick Function in Multirotor Modes
The figure below shows the behavior of the multirotor when the control stick is moved, for the presently
selected flight mode.
5.10.3 2D Hold Flight Mode Information for Fixed Wing
When 2D Hold flight mode is selected for fixed wing, both heading hold and altitude hold will be enabled.
Heading hold uses the ailerons or elevons to hold the present heading, and altitude hold uses the elevator.
The altitude hold's lock is reset every time the elevator stick is moved.
Also, note that if the Vector detects stall-like conditions (severe roll), or the model is traveling at a ground
speed (based on the GPS) that is less than the “Minimum Ground Speed” setting on the Safety Setup tab of the
software, both altitude and heading hold will be temporarily disabled.
Since the Vector will use the elevator to attempt to hold the present altitude when the control stick is
centered, it’s important that sufficient airspeed be maintained when in 2D Hold mode, to avoid a stall!
Also, caution should be used when attempting to land in 2D Hold mode.
If you want to have altitude hold disabled in 2D Hold mode when your current draw is below a certain level (or
permanently if you are flying a sailplane without a motor), an altitude hold disable feature is available.
To enable this feature, enter a nonzero amperage value in the “Disable Altitude Hold
when Amps are lower than ___ Amps” setting, on the “Flight Controller Setup” tab of the
software. When set to a nonzero value, and when the Vector detects amp draw below
the chosen value, altitude hold is turned off when 2D Hold flight mode is selected during
normal flight, and during RTH. Setting this to 0 disables the feature.
5.10.4 Programming the Mode Switch
During flight, you can change the Vector flight mode using
your mode switch, and optionally a submode switch for
additional flight modes. The position of the mode switch
determines the flight mode, and can also be programmed
to turn off the OSD screen during flight.
At least one “non-GPS” flight mode must be
configured on the mode or submode switches. Non GPS
flight modes, such as 2D and 3D, do not have the “(GPS)”
