Gain Adjustment - HOBBYEAGLE A3 PRO V2 User Manual

The ANGLE mode, also known as the 'Trainer mode' or 'Attitude mode', will limit the maximum angle of
the airplane on both roll and pitch axes. Roll and loop are not allowed in this mode, the airplane will be
stabilized all the time, independent of any stick input. This prevents the airplane from being tilted into a
larger angle that may cause a danger. As soon as the sticks are released, the airplane will be brought
back to horizontal position automatically. You can use this mode as emergency rescue, or in other
applications, e.g., to have a training for new beginners or to use for FPV. The maximum allowed angle
can be set in the Setup Menu. In addition, changing the stick rate can also affect the max tilt angle.
5. LEVEL Mode
The LEVEL mode is also known as the 'Auto-Level mode', 'Auto-Balance mode' or 'Horizon mode'. When
operating in this mode, the airplane will be brought to horizontal position automatically when releasing
the sticks. Different from the ANGLE mode, there is no maximum angle limitation in this mode and the
airplane will be stabilized only when there is no specific control input from aileron and elevator sticks.
This mode can be used if the pilot becomes disoriented and would like to save the airplane from crashing.
6. HOVER Mode
The HOVER mode, also known as the 'Auto-Hover mode', provides the same functionality as the LEVEL
mode. The only difference is that when you release the sticks, the airplane will be brought to vertical
position (nose up) and keeps hovering. This mode is designed to help you to learn hovering maneuver
and reduce the probability of crashing.

GAIN ADJUSTMENT

Basic Gain
There are 3 trimming potentiometers on the front of the A3 Pro V2. They are used to adjust the basic gain
of the gyro for Aileron, Elevator and Rudder separately. Clockwise for increase, anticlockwise for
decrease. Basic gain determines the momentary reaction strength of the gyro. In general, the higher the
gain the harder the airplane will stop after rotation and the more stable and precise the airplane will fly.
But if the gain is too high the airplane will tend to oscillate at high frequency on the corresponding axis. If
too small, the operation and stability will not be so good and the airplane does not stop precisely and
overshoots. The gyro will be deactivated completely if you turn the basic gain to 0%.
For the first flight test it is recommended to start with a lower basic gain setting (e.g. 30%) and switch the
gyro to NORMAL mode. In case the airplane starts to oscillate in flight then reduce the gain of the
corresponding axis. If the control feels weak and imprecise and does not hold position when stopping
then increase the gain, according to this approach, fine tune the basic gain until you get the best
performance.
