Using a CX10 quadcopter for the first time.

I bought one of these little Cheerson CX10 quadcopters from an online supplier and when it arrived it was a bit frustrating to get going because the instructions were not in very good English. But I worked it out and it's a great little thing.
The purpose of this video is to save you the grief of decrypting the instructions so you can just get on with playing with the thing.
Things worthy of note are that there are two types of blade. Clockwise and counterclockwise. If you put them on the wrong motor the quadcopter will do very weird things. I recommend putting a marker pen dot on one diagonally opposing set of blades as soon as you get it. There are spare blades of either type and you will need to compare them for the way the blades slope if you have to put new ones on.
The charging circuitry is built into the USB plug. A red LED shows when the charge has completed. Do not leave the quad on charge continually and do not leave the charging lead plugged into it when it's not charging as it may run the battery down.
There are two types of controller. Left hand throttle and right hand throttle. The throttle makes the blades spin faster and the quad lift upwards. It's the only joystick movement that doesn't have spring loaded return to centre. That same joystick also does the "rudder" function that makes the quad spin on the spot in either direction.
The other fully spring loaded joystick is for backwards, forwards, left and right (in non geek-speak.)
The remote control needs two AAA alkaline cells to operate.
After charging the quad you will need to pair it with the remote controller each time you use it. To do this, turn on the quadcopter and place it on a flat surface. It's LEDs will be blinking. Place it with the red LEDs towards you (it's rear). Then make sure the remote controller has it's throttle joystick fully moved towards you (the side with the on-off button) and then turn the remote controller on and after a moment push the throttle fully forwards and you'll hear a beep and see the quad's lights react. Now pull the throttle fully back again and you're ready to fly.
To calibrate the quadcopters accelerometers/gyro put it on a flat surface and push the non-throttle lever up to its top left position and then move the throttle lever to its lower left position. If successful the quad's LEDs should blink on one side after a second or two.
To fly the quad after pairing, ease the throttle forward slowly until the quadcopter starts lifting off the ground. It requires a delicate balance to keep it at a specific height, so don't get too violent with the throttle lever. If the quad drifts in still air then you can compensate with the two pairs of trim buttons that adjust the effective centering position of the steering control.
After that it's really just down to playing with it to get a feel for how it flies and behaves.
If it crashes put the throttle down to the bottom position immediately. But if the motors stall the quad will go into standby mode immediately and flash all its LEDs to aid location. It will need switched off and on as will the controller for pairing again.
If the quad refuses to fly and just flashes its LEDs then it may need recharged.
Enjoy. These things are great to play with.
