RadioLink SU27 Unboxing & Setup
Here is the packaging box. Unbox it.
Here are 2 manuals. One is for SU27 and the other one for transmitter T8S.
SU27 comes with a T8S transmitter. Users can choose other RadioLink transmitters and receivers to control SU27. Optional RadioLink transmitters include T8S, T8FB, T16D, AT9S Pro, and AT10II.
(Note: Please refer to the sales interface for the actual packing list.)

Here is a charger CM210 and a 2S lipo battery. You can use CM210 charger to charge this 2S lipo battery.
Here is SU27 fuselage.
Here is the accessory box, with all the other accessories. Here is a Charging&update cable for T8S transmitter.
Here are fiber tape, a screwdriver, a propeller and Spare Rudder Angles.
Here are vertical tails of SU27.

When you receive SU27, you need the 4 parts here. SU27 fuselage, vertical tails, T8S transmitter and the battery.
For assembly, you just need to install the vertical tails, which is simple. The tail with colors faces outward. Insert the vertical tail until you hear a click. The same way for the other tail. Now it is done.
Install the battery, Fix it with the band.

Power-on and Gyro Self-test
Power on T8S transmitter first. Push the throttle stick of the transmitter to the lowest position and then power on the aircraft. (Note: The binding has already been done by factory default. So you don’t need to bind the transmitter and receiver.)
Keep SU27 in a stationary state. The gyro of the flight controller will perform self-test. The self-test is done now.
Move the joystick, the control surface moves, so the connection is successful.

Motor Safety Lock
The motor can be locked/unlocked by channel 7, the switch here.
Push the switch up, the motor is locked. There is no throttle when you push the throttle stick.
Push the switch down or center, the motor is unlocked. The motor emits two long beeps means the unlocking is successful. You must push the throttle joystick to the lowest position when unlocking it, otherwise the unlock will fail.
(Note: When the motor is locked, the gyro of Byme-DB is automatically turned off; When the motor is unlocked, the gyro of Byme-DB is automatically turned on.)

Flight Modes Setup
The right switch here is used to control flight modes. SU27 has 3 flight modes.

Push the switch down, it is Stabilize Mode, which is suitable for beginners.
Push the switch in the center, Gyro Mode, the advanced flight mode.
Push it down, Manual Mode, with no gyro involved.

Attitude Calibration
Byme-DB needs to calibrate the attitudes to ensure the balance status. It is recommended to lift the aircraft nose with about 20 degree angle for beginner to ensure smooth flight.
I place a box under the nose like this. Then push the left stick (left and down) and the right stick (right and down) like this to calibrate the attitude. The green LED flashes once mean the calibration completed. and attitude calibration will be recorded by flight controller once the it is complete with success.

Servo Phase
After the attitude calibration is done, test the servo phase.
Toggle the switch of CH5 to Manual mode. Then check if the the movement direction of the ailerons/tailerons is consistent with the joystick movement. Take Mode 2 for transmitter as an example.

When the movement direction of the ailerons is inconsistent with the joystick movement, adjust the servo phase by pressing the buttons on the front of the Byme-DB. Here it is.
After all the test above, you can fly it outside. You can hold SU27 in hand like this. Push the throttle and throw it.
