Here are my observations regarding the most important things when flying a Phantom drone:

- Don't ever fuck around with low battery. Get it home with 20% or more. It will auto-land at 10% battery. (You might be able to adjust this setting, I haven't checked yet, but I've also heard about drones falling out of the sky when at lower than 10%.)

- If at critical battery, push UP on the left stick to stop the auto landing, and then use the right stick to control where it auto-lands.

- Keep it high in order to maintain better line-of-sight and not lose communication with it.

- MAKE SURE HOME POINT ON MAP IS UPDATED CORRECTLY. When flying in Mammoth once, I accidentally took off with the home point still set to somewhere in the LA area. It should have updated itself properly, but it didn't. Fortunately I noticed this and flew it back home manually, then made sure it updated before taking off again.

- Keep away from high-tension power lines. These can sometimes make the drone act crazy and get confused regarding the GPS coordinates, thus causing flyaways.

- Put on "multiple flight modes" in the DJI app, and then be ready to switch to "A" mode on the controller if the drone freaks out and flies away. You get manual control at that point, and GPS flight is disabled. I've never had to do this, but it's a good tip.

- Stay under 400 feet above the ground, or otherwise if you hit any aircraft, you will be liable (and maybe kill someone!)
