Lets Start Flying Shall We?

First you must choose your area of training, i suggest you start inside your house (even if your drone is big), or in the garage (you should have an ample space to fly with the less obstacles possible).

Why inside the garage or inside the house? Because flying without wind its easier.
First you must feel confortable with flying, and dont be affraid to crash.
There are simple methods to make your drone survive for 90% of your crashes, but those will be explained after the basics.

Now that you have your "training area" defined you can adjust yourself to the controler.

Go easy with the controller, use sensible and slow movements, if you start going up and down with the left joystick you will have a bad time.
Try to understand where is the stable point of the drone, and if you are going to crash just put the left joystick down (all down, or the helices will not stop).
Don't worry you are protecting your apparel with that fall ;)
