Gain Adjustment - Eagle A3 Pro Instruction Manual

release the sticks, the plane will be brought to vertical position (nose up) and keeps hovering. This flight mode is designed
to help you to learn hovering maneuver and reduce the probability of crashing.

GAIN ADJUSTMENT

There are 3 trimming potentiometers on the front of the A3 Pro. 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 plane will
stop after rotation and the more stable and precise the plane will fly. But if the gain is
too high the plane 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 plane 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 plane starts to oscillate in flight then reduce the gain of the corresponding axis. If the control feels weak
and imprecise and doesn't hold position when stopping then increase the gain, according to this approach, fine tune the
basic gain until you get the best performance.

REMOTE MASTER GAIN
The [PPM/Bus/G] is used to control the master gain remotely. You can make a linear adjustment by using a knob or slider
on your transmitter, or make a 3-level gain control using a 3-position switch. However connecting this channel is not a must
if you don't connect it the master gain will always default to 100%.

ABOUT SETTING METHOD
There are three menu levels. Function Menu, Setup Menu and Receiver Menu. They can be accessed by the following
ways:

To access the Function Menu, from ready mode (while the gyro is operating), press and hold the button for 2 seconds,
release the button when LED lights solid White.
 To access the Setup Menu, from ready mode (while the gyro is operating), press and hold the button for 4 seconds,
release the button when LED starts flashing White quickly.

To access the Receiver Menu, press and hold the button while turn on the receiver power supply, release the button
when LED lights solid Violet.
