The FC and ESC should come with multiple connection cables for the ESC to FC Connection.
**Note that when using plugs, ALWAYS be sure to always confirm the pinouts of the plugs before plugging in and applying power.
Be sure to use the correct cable to connect the ESC to the FC. The Cable will have a 10 Pin on the ESC side and a 8 Pin on the FC side. There will be one wire missing from the middle, and the White and Black wires from the two plugs will be crossed between the two ends of the plug. See diagrams below.
