Manual of Multi copter Controller i86LManual of Multi copter Controller i86L

Thank you for purchasing this product, i86L is a flight control board designed specifically for remote control multi-

copters with 3.4and 6 rotors. With a high-precision MEMS digital three-axis gyro built in, it provides sound stability,

flexibility and reliability by automatically correcting for axes of pitch, roll and yaw. Specifically optimized software put

in place for sport flight mode without undermining stability, whether you are a beginner or advanced, it can bring to

you the most excellent performance!

1. Supports 6 multicopter types including Tri Copter, Quad+4Copter, Quad×4Copter, Hex Copter, H6 Copter and Y6

Copter, can be switched by the on-board Coding-Switch;

2. 2 flight modes to choose from for each type, including Normal Mode and Sport Mode;

3. The throttle lock function has been canceled in i86L it is ready for flight any time when the blue LED turns ON;

4. Independent gyro gain adjustment for pitch, roll and yaw;

5. Basic setting modes including stick centering and ESC throttle calibration;

6. Blue and red LEDs for working status display and error report.

The board should be securely mounted in the center of

your multicopter applying the provided double sided tape.

Please align the white arrow with forward flight direction

when mounting. Inappropriate or inaccurate installation

Could decrease the performance of the board or even

Result in complete failure.

【Installation & Wiring】

After installation, connect the channels of Aileron, Elevator and Rudder from your receiver to the pins on the board

marked No. 1 to 4, and the ESCs (or servos) to the pins marked M1 to M6 in the correct order according to the

selected multicopter type (See P4 “Supported Multicopter Types”).When connecting, please pay attention to the

color of wires to avoid anti-plug. The WHITE (or YELLOW) signal wires should be connected corresponding to the

inner pins on the board, the RED（VCC）wires to the center pins, and the BLACK(GND) wires to the pins on the

outer edge of the board, as shown below:

【Multicopter Type & Flight Mode Selection】

Notes: “0” represents “OFF”, “1” represents “ON”, “X” represents influence-proof for the mode set. i.e. Modes

between normal and sport are either available for any multi copter types; “▲” is the default setting.

【Stick Centering】

The Stick Centering Function is used to calibrate channel range of aileron, elevator, throttle and rudder. To obtain the

highest performance it is recommended to apply this function after first-time installation or application of new radio

system. Follow the steps as shown below:

Step 1 Set the coding-switch to the “Stick Centering Function”, see “Multi copter Types Setting Table”,

Step 2 Turn on the transmitter, set the trimming of channel aileron, elevator, throttle and rudder to zero, keep the

throttle stick in the bottom position, the other sticks in the middle;

Step 3 Power on the board. Both the blue and red LEDs will begin flashing simultaneously for once

after initialization, this indicates that the board is entering the stick centering function. Wait for

1 second. Both the blue and red LEDs will flash 4 times quickly, this indicated that system

is calibrating signals. Don’t move the sticks during this process;

Step 4 After calibration done, the blue LED will turn ON and the red one OFF, please turn the power off and restore

the setting of the coding-switch in order to avoid entering this function next time.

【ESC Throttle Calibration】

The ESC Throttle Calibration Function is used to setup the throttle range for the ESCs. To obtain the best linearity

we strongly suggest you apply this function after first-time installation or application of new ESCs. Follow the steps

as shown below:

Step 1 Set the coding-switch to the “ESC Throttle Calibration Function”, see “Multicopter Types Setting Table”,

Step 2 Turn on the transmitter, move the throttle stick to the top position;

Step 3 Power on the board. Both the blue and red LEDs will begin flashing simultaneously for twice after

initialization, this indicated that the board is entering the ESC throttle calibration function.

Wait for 1 second. The blue LED will turn ON and the red one OFF, this indicate that system

Is ready to output signal to the ESCs. Please move the throttle stick to the bottom when the

tones of throttle range highest point has been confirmed. Specific construction shall be

referred to the manual of your ESC;

Step 4 Once you have completed setting up the ESCs simply turn the power off and restore the setting of the coding-

Switch in order to avoid entering this function next time.

i86L has a 4-bit coding-switch for multicopter type and flight mode selection, the first 3 bits for multicopter type and

the last bit for flight mode. Please restart the board to activate the selected type or mode. VERY IMPORTANT!

Manual of Multi copter Controller i86L 【Gyro Gain Adjustment】 i86L offers 3 trimming potentiometers to adjust the gain of pitch, roll and yaw gyros, clockwise for increase, anticlockwise for decrease. The most suitable volume is determined by many factors, such as fuselage size, weight and power allocation used. We strongly suggest you put the gain at a lower volume for the first flight, and then fine tune to get the best result. The adjustment will take effect immediately without needs to restart.
