Pinch the top and bottom tabs of the battery case, pull the battery straight out to remove it.
The metal connectors form a stiff mechanical connection with the battery, you will need quite a bit of force to remove the battery. Hold the Phantom Vision+ with one hand and remove the battery with the other.
Determine if the propellor is clockwise or counter-clockwise rotating.
Each arm is labeled with a rotation icon that shows the direction of propellor rotation.
If this icon is missing or you can't read it, you can determine the direction of rotation by examining the propellor.
A clockwise rotating propellor pushes air down while rotating clockwise, and the opposite is true for a counter-clockwise rotating propellor, and the propellor blade slopes up in the direction of rotation.
