If a gain value is excessively high for your airframe, the oscillations can make the model become
uncontrollable! If the Vertical/Altitude gain is set too low, RTH may not work correctly!
When you are in 3D Heading Hold (Direct Rate) mode, the basic gains dictate how strongly the controller will
work to keep the model in its current orientation.
Stabilizer Responsiveness
The responsiveness control is applicable only in 2D (leveling) modes. The responsiveness dictates how
smoothly the model will follow the user’s stick commands. A higher responsiveness will make your model
more stiff and twitchy. A lower responsiveness will make the model feel slower, and more fluid. It is
recommended that you change responsiveness only one increment at a time, as a small change can have a
significant impact on handling.
6.12.1.2 Adjusting Gains
The MicroVector gains are adjusted by invoking menu mode, selecting “Stabilizer Settings” from the main
menu, and changing the gains from that menu.
NEVER use gain settings specified for a different controller with the MicroVector! Gain values are NOT
interchangable between flight controllers!
It is recommended that gains be adjusted up or down in small increments (about 10% at a time) until the best
setting is found. The chart below shows how too high or too low gains can affect flight:

6.12.1.3 Gain Adjustment for Initial Flight
The default gains for the MicroVector were chosen so that most airframes will fly reasonably well
without major adjustments.
