As it says: Be sure to remove all propellers from the vehicle before proceeding.
During setup the motors may spin. This may cause them to bounce around even if they are just sitting on a table. You may want to secure them. Only secure the bases as the top parts spin.
Firmware Update. Update if needed.
Board Identification: Should come up by itself. Mine says: Connection device: USB: CopterControl Detected Board type: OpenPilot CopterControl 3D
Input Signal Configuration: PWM (1 Cable per Channel)
Vehicle Type Selection: Multirotor
Multirotor Configuration: Quadcopter X.
Output Signal Configuration: Rapid ESC
Configuration Summary: Save Connection Diagram
This diagram tells us how to connect the wires. If you look at the Flight Controller it has an arrow on it. That arrow points in the same direction as the red arrow in the diagram. It is expect the motors to be connected in the order shown in the diagram. So Motor 1 is to the North West of the Flight Controller, Motor 2 is the the North East of the flight controller, Motor 3 is to the South East, and Motor 4 is to the South West. (If you screw this up your copter will almost instantly rip itself apart when you start it up. Because as one side dips the Flight Controller will spin the correct motor faster to compensate but if it is connected to the wrong motor it will create a destructive feedback loop.)
The numbers correspond to the channel that you should connect to. So the PWM1 from the flight controller connects to the ESC for Motor 1. PWM 2 to the ESC for Motor 2. etc...
The left of the diagram is the connections to the Receiver. So the first problem is that the Receiver uses different words for each of these. (The wording printed on the Receiver is for a airplane not a quadcopter.)
This is how they connect:
Channel | Flight Controller | Receiver |
CH1 | Throttle | THRO |
CH2 | Roll | AILE |
CH3 | Pitch | ELEV |
CH4 | Yaw | RUDD |
