How to setup gains and correction directions?
There are 3 pots to adjust the correction directions and gains for
aileron (roll), elevator (pitch) and rudder (yaw) channel. please
see the sketch below.

6-axis Flight Control
MODE
● It needs a few testing fly to determine appropriate gains, we
recommend starting from conservative gains (low) first.
● Fly in aerobatic mode at safety altitude, accelerate the airplane
to its maximum speed to see if there is oscillation in pitch, roll or
yaw axis. Oscillation indicates the gain is too high, please slow
down the airplane, decreasing the Gain after landing.
● Please don't change too much gain at one time, We
recommend adjusting 5-10 degrees once.
Ground Test
● Please do a ground test before first flight.
● Test if the mode switch is working properly. Do not turn on the
motor/engine, toggle the mode switch on the transmitter to middle
position, LED2 will turn GREEN for 0.5sec, now FC151 is in
Aerobatic mode.
● Test transmitter moving direction. Move the sticks (except the
throttle) to see if each control surface is working rightly.
● Test gyro
correction direction. Rotate the model on each axis,
corresponding control surface should act to against that rotation
(see below). If the action is wrong, please reverse the pot of that
axis.
