Flight Modes
A3-L Supports 3 flight modes, you can switch between them using a 3-way switch on the transmitter. But if you are
using a 2-way switch instead then you can only use 2 of them during flight. The color of the LED shows you that the
flight mode currently selected, as shown below.
Gyro Directions
It’s extremely important to verify that the gyros of all
channels are reacting in the correct direction before flight,
otherwise it could lead to losing control or even crash
during a flight!
To perform the examination, power on the
plane, pick it up and check by following the steps in the
figures on the right. If the gyro compensates in an incorrect
direction, reverse it at once!
Aileron
Quickly move the right wing downward
around the roll axis. The right aileron surface should flap
down and the left flap up.
Elevator
Quickly move the nose of the plane downward
around the pitch axis. The elevator surface should flap up.
Rudder
Quickly move the nose of the plane to the left
around the yaw axis. The rudder surface should flap right.
