This video was made to help you understand the steps to take in order to get the Potensic D80 quadcoper to fly. It's more than just connecting the battery and turning it on, but not much more.
Skip to 8:20 if you want to see the quick, 1 minute, demonstration of what to do once the battery is charged.
I am a huge fan of this drone! It's got a lot of great features for a very reasonable price. You will probably want to buy some additional batteries because the flight time of 20 minutes is never enough for how much fun you'll have.
