To assemble the ESC to your motors, you have to link the part with 3 cables, with the 3 cable from the motor
To assemble the ESC to the power, you have to link the red one to the positive side of the battery, and the black to the negative side. It will help to have a distribution power board, to keep it organized, since you have to link 4 ESC to the battery
To assemble the ESC to the control board, you have to connect the 3 colored cables(the thin ones) to the right side of the board, with the black or brown cable to the edge of the board. You don't have to connect power to the control board, these colored cables already bring the power.
Connect the RX part or the radio to the left side of the control board, you will have to test your TX to see which cable goes where.
When you configure your KK2.0 control board, it will show to which direction the motor should rotate, having that in mind put the propellers in the way that they will always push the air down. You will have two types of propellers.
If the motors is running the wrong way, you only have to switch 2 of the 3 cables that go from the motor to the ESC, than it will go the other way
Put that all in the frame, and you are good for testing.
Before going on open air, I recommend to test it attached to the ground by some thread. When it is all tested, you are good to go.
Great flying to all!
