Eachine E186 1:27 Scale Bell-206 RC Helicopter User Manual
This document provides comprehensive instructions for operating the Eachine E186, a 1:27 scale replica of the Bell-206 helicopter. It features a highly realistic detailed appearance, cool lighting effects, intelligent flight control, an optical flow positioning module, and an altitude hold module. With its dual brushless motor drive, it is especially suitable for beginners and can also serve as an excellent static display model.

Remote Control Overview
The remote control is designed for intuitive operation and features various controls for managing the helicopter's flight.
Controls and Joysticks
Left Joystick (Accelerator/Direction): Controls throttle (up/down) and yaw (left/right direction).
Right Joystick (Ailerons/Elevation): Controls roll (left/right) and pitch (forward/backward).
Dials: Two right-hand dials for fine-tuning controls.
Rudder Volume Toggle: A toggle switch to adjust rudder volume. Moving the toggle to the right selects large rudder volume (indicated by two beeps). Moving it to the left selects small rudder volume (indicated by one beep). The factory default is small rudder volume.
Buttons:
- Motors Unlock/Lock: A switch to enable or disable motor rotation.
- One-button Landing: Initiates an automatic landing sequence.
- Throttle High/Low: Adjusts motor power.
- Lower Visual Mode: Toggles between different flight modes.
Modes and Calibration
MODE Conversion: The factory default mode is MODE2, indicated by the remote control lighting up blue. To switch to MODE1, press the MODE button while powering on the remote control; it will light up red and blue.
Joystick Calibration: To calibrate the remote control joystick: Move the rudder control button to the right and power on the remote control. The remote will beep three times. Keep the remote control still during calibration for accuracy.
Operation Procedures
Frequency Pairing (Binding)
Follow these steps to bind the remote control to the aircraft:
- Toggle the small rudder volume key to the left. Simultaneously, turn on the remote control to enter frequency pairing mode. The remote control will emit a dropping sound, and its indicator light will flash rapidly.
- Power up the flight by turning on the aircraft's battery switch. The aircraft's indicator light will flash rapidly yellow.
- Approach the aircraft to the remote control within a distance of 0.5 meters and keep the aircraft stationary.
- The remote control will emit a dropping sound, and its indicator light will turn solid. The aircraft's indicator light will also return to solid green. This indicates that frequency pairing is complete.
- If frequency pairing is not successful, please repeat the above steps.
Motor Control
Unlock/Lock Motors: The 'Motors Unlock/Lock' switch is used to control motor rotation. Switch up to unlock and allow motors to spin. Switch down to lock and stop the motors. Warning: Locking the motors while in the air will cause the motor to stop and the aircraft to crash.
Stopping Motors After Landing: After the aircraft has landed, ensure the throttle rocker is in the lowest position and hold it there for more than 3 seconds to stop the motors.
Flight Modes
The aircraft supports different flight modes controlled via a toggle or dial:
- Optical Flow Mode: Activated by toggling the control upwards (or to the 'Up-dial' position). The aircraft status indicator light will be green. This mode provides stable hovering and positioning.
- Manual Mode: Activated by toggling the control downwards (or to the 'Down dial' position). The aircraft status indicator light will be red. In this mode, altitude restrictions are lifted, allowing for faster flight speeds, potentially up to 10 meters per second. Operate with caution in manual mode.
Pressing the manual mode button turns off the optical flow flight mode and lifts altitude restrictions.
Inverted Flight
The E186 helicopter can perform a 180-degree inverted flight:
- Fly the aircraft to a height of 5 meters or more.
- First, switch to the large rudder volume state.
- Then, switch to manual flight mode.
- Press the inverted flight button for two seconds to enter the one-key inverted flight mode.
- To perform the roll, quickly hit the aileron rocker left or right and then quickly return it to the center. The aircraft will automatically enter a 180-degree roll and hover.
- While in the inverted flight state, operate the helicopter using the throttle rocker for climb/descent and the aileron rocker for forward/backward movement.
- To return to normal flight, press the one-key inverted flight button again, and quickly hit the aileron rocker. The aircraft will roll forward and return to normal flight.
Note: The aircraft only supports aileron rolls (left or right), not forward or backward rolls.
Pitch Setting
This procedure allows for precise adjustment of the helicopter's control surfaces for optimal stability:
- Power on the aircraft and bind it to the remote controller.
- First, set the throttle lock switch to the locked state.
- Long press the pitch setting button (listen for two beeps) to enter the pitch setting mode.
- Adjust the corresponding servo using the rocker controls until the aircraft's cross disk is horizontal and the angle of the propeller is 0 degrees.
- Short press the lock button (listen for a dropping sound) to exit the pitch setting and save the configuration.
