Depends on what you spend.
Depends upon what you spend. They are electric, battery powered. They have an endurance of 7 to 10 minutes, and the batteries take 25 to 30 minutes to charge. Extra batteries often cost as little as $4. They don't report speed, direction, or altitude that I'm aware of. They are visually controlled. At least the ones I've read about. The one I ran sent back the camera pictures to a laptop.

There are some things in common. They all seem to have a default of a level hover. So if you lose control just lift your thumbs. It will go into a hover. The range is that of a garage door opener, about 300 feet, and is limited by the power of the transmitter and receiver. If you send it out of range, it will crash into something. The more expensive ones will return to its' last launch position, being guided by an onboard GPS.

They take pretty good film and either transmit it back to a receiver, and/or record it to an SD card.

The one I flew was rather sophisticated, but took about 20 seconds to learn the basics. The owner trusted it to me and a number of other people and it survived them all.
