Fotokite's foldable, tethered Phi flying camera

Most camera drones rely on GPS and sensor systems to make them easier and safer to fly. The camera? Uses only one character string.

This is an oversimplification, but not much higher. Φ is attached to a roll by an 8- or 30-meter tied belt (26 or 100 feet). The belt has its own processor and sensor allows you to control the φ by holding a button and moving the belt in the direction you want to go. Without it fly away from your fear or drifting to other people and things, learning without complicated control.

The crowdfunders were designed to resonate back from the supporters of Indiegogo back to $ 413,495 last September. Originally expected to ship early this year, but the procurement and production problems postponed until now. Φ is available for a limited time at a price of $ 249, from short time to the best I can tell I have spent it, and it is all camera promises.

The ultra-lightweight, φ-fold down, perfectly fit in a tube-sized whiskey bottle also comes with a camera and weighs only 400 grams (14 ounces). Do a good job flying, you fold off the arm and twist lock. Currently available for Hero3 / 3 + Hero4 and Hero5 session cameras, you can start and stop recording and take pictures directly from the reel.

Hold the four from the bottom and you give it a quick twist to the wrist (similar to a bulb twist) and the props to spin up. Then you just let go, let some belt. Φ in response to the tension line, then in order to raise and lower or rotate the roll in place or twist your hand in the direction you want to go.

The time of flight is detachable, rechargeable battery is about 13 minutes. Although you get a warning that the battery life is low when the front of the φ soon land itself the battery is completely exhausted. The same if the range is reduced, so you never have to worry about it flying. The propeller is soft and spins at a lower speed than other UAVs, also increasing its safety.

Camera φ may not have the typical radio control range and capabilities of a four-axis aircraft, but I guess you can fly in more places, especially in a typical UAV may not be allowed. If you already have a camera that is also equipped, and the investment is very low.
