Introduction
About Byme-D
Byme-D is applicable to all model airplanes with mixed elevator/aileron controls including delta wing, paper plane, SU27, F22 and is SBUS and PPM signal supported. There are three flight modes: Stabilize Mode, Acrobat Mode, and Manual Mode.

Weight(With wires)4.5g0.16oz
Channel Quantity3
Integrated Sensorthree-axis gyroscope and three-axis acceleration sensor
Signal SupportedSBUS/PPM
Input Voltage5-6V
Operating Current25±2mA
Installation
Make sure the servo phase adjustment button on Byme-D points to the aircraft head, and the pin end of Byme-D points to the tail of the aircraft. The flight controller can be installed either face up or down with 3M glue on the aircraft body and the wires connect to the corresponding pins. It is recommended to install Byme-D near the center of gravity (of the aircraft). Please install Byme-D as shown below. (Note: Wrong installation direction and position of Byme-D will lead to inaccurate correction of the flight controller, and it is difficult to achieve the best flight effect).
Transmitter Setup
- Channel 5 (three-way switch) is used to switch among 3 flight modes, and channel 7 is used to lock/unlock the motor. Therefore, only a transmitter with 7 channels or more is available.
- You cannot set any mixing function in the transmitter when Byme-D is mounted on the aircraft. Because there is already the mixing function in Byme-D. The mix control will automatically take effect according to the flight mode of the aircraft. If the mixing function is set in the transmitter, there will be conflicts in the mixing function and then affect the flight.
- Set the direction of the channel as below: CH3 – Throttle: Reversed Other channels: Normal
Power-On Calibration
When the aircraft is powered on, the gyro on Byme-D will calibrate with the green led flashing. Please keep the aircraft remain still until the green light is always on.
Attitude Calibration
The flight controller needs to calibrate the attitudes/level to ensure a balanced status. It is advised to lift the model head at a certain angle to ensure calibration accuracy.
Push the left stick (left and down) and the right stick (right and down) as below and hold for more than 3 seconds. The green led flashes once mean the calibration is completed.
Note: If you set the direction of the channel as above(CH3 – Throttle: Reversed, Other channels: Normal), but the attitude calibration cannot be finished by pushing the left stick (left and down) and the right stick (right and down), please enter the menu of the transmitter to set the direction of the channel. The direction of the throttle channel still remains reversed. But for other channels, please try the following 3 combinations to set the channel direction and then calibrate the attitude by pushing the left stick (left and down) and the right stick (right and down):
Combination 1: Channel 1- Normal, Channel 2- Reversed
Combination 2: Channel 1- Reversed, Channel 2- Normal
Combination 3: Channel 1- Reversed, Channel 2- Reversed
When the attitude calibration can be done by pushing the left stick (left and down) and the right stick (right and down) with any one of the above combinations of the channel direction, save it and do not make any modifications. After the attitude calibration is finished, please check the servo direction next.
Servo Phase
Make sure the servo phases are correct before flight. Take Manual Mode and Mode 2 as example. (Please refer to Flight Mode in the manual for mode switching)
When the movement direction of the aileron is inconsistent with the joystick, please adjust the servo phase through the buttons on the front of Byme-D. Please do not change any settings of servo direction on the remote control at this time.
Press the button at the front of Byme-D to change the servo phase:
Short press once, aileron mix control reversed, LED1 ON/OFF.
Short press twice, elevator mix control reversed, LED2 ON/OFF.
Note: Make sure attitude calibration is complete before changing the servo phases. Byme-D will identify the installation position(above/bottom of the aircraft) to automatically adjust the gyro direction.
Flight Modes
Flight modes can be set by CH5 (3-way switch) on the transmitter. There are three modes: Stabilize, Gyro and Manual.
Stabilize Mode
The model attitude (inclination angles) is controlled by joysticks. The max inclination angle is 70° for rolling while that for pitching is 45°.
Gyro Mode
The model rotation is controlled by joysticks with gyro increasing the stability. This is an advanced mode. The model won’t level but and keeps rotating when joystick is loose.
Manual Mode
Pilots control servos with corresponding channels by the transmitter, neither attitude nor gyro involved.
Motor Safety Lock
The lock can be turned on/off by CH7 (2-way switch) of the transmitter.
Gyro Sensitivity There is a certain stability margin for the Byme-D PID control.
To different models, if Byme-D is under correct or over correct, pilots can try adjusting the rudder angle.
