However, airframe types vary widely, so the default gains may cause problems with your model. There are
three ways to reduce the likelihood of gain related problems with your first flights:
a) Set up a gain knob as described below, so you can control the gains of one or more axes quickly from your
radio, during flight. To do this, you will need to map a knob from your transmitter, as described earlier in
the manual. The Gain Knob works differently between fixed wing and multirotor models, as described
below.
b) Program your Mode switch so that one or more positions will invoke a flight mode that does not do 2D
leveling, in case you need to switch quickly out of leveling mode due to gain or other issues.
c) Check an RC forum to see if anyone has posted good MicroVector gain settings for your particular airframe.
Don’t use gain settings for other controllers with the MicroVector!
6.12.1.4 Configuring the Gain Knob for Fixed Wing
For fixed wing, the gain knob controls overall gain, which scales (multiplies) the pitch, roll, and yaw gains
all at once. The overall gain can be turned to zero (stabilization off) at the lowest knob setting, which
effectively lets you use the knob as a stabilizer on/off switch.
For fixed wing, the present value of the gain knob is displayed in the notification area each time you turn the
knob. This readout can be used for setting the “Default/RTH Overall Gain” menu item. Once you find a good
overall knob gain setting for your model, you can set this menu item to the value displayed for the knob, which
will then be used during RTH, or if the gain knob is otherwise not available.
6.12.1.5 Configuring the Gain Knob for Multirotors
For multirotors, you can select which of the individual basic gains (pitch, roll, yaw, and/or altitude) that
will be controlled by the knob. To select which axes are controlled by the gain knob, invoke menu mode,
select “Stabilizer Settings” from the main menu, and change “Knob for X Gain control?” to “Yes” for each
gain you want controlled by the knob.
For multirotors, the knob will adjust the gains from 50% to 200% of their default values. To see the present
settings for these gains, navigate to the Stabilizer Settings menu item, and observe the values displayed.
Values that are mapped to the knob will change in real time on the menu screen.
The basic gain settings(s) are remembered each time you rotate the gain knob. If the gain knob is later
disconnected or disabled, the remembered settings are still used.
6.12.1.6 Advanced Gains and Performance Settings
Advanced users who fully understand stabilizer concepts can
make advanced tuning and performance adjustments in the
“Advanced Multirotor” and “Advanced Stabilizer Setup” stick
menus, or in the “Advanced Flight Controller Setup” tab in the
software.
Don’t change advanced gain settings unless you know
what you are doing!
PID Gains: The MicroVector employs an “Inner/Outer Loop
Flybarless PID Controller” design. Specific loop gains are
adjustable in the “Advanced Setup” menu.
