The Drone is really pocket size as well as very impressive at its first look. I have been playing with this drone for over a month now. It flew very well in the beginning, but recently I have encountered an issue where the drone starts drifting towards its left as soon as i push the throttle. I tried doing the calibration, but it doesn't work. Also tried replacing all gears and fans, still didn't work- seems like an issue with inbuilt mechanism. The most frustrating part is that the flight time is just too low "max 2min"; even with 30% speed and efficiency. I bought an extra battery, but one doesn't seem to enjoy the flying with constant replacing of the battery. The flight time should have been alteast 5 to 8 min.
Really it has good picture quality.but wifi is disconnect within 15 to 20 ft only n if u cross beyond u loose control of it. Even if it knock down for few time it malfunctions. May b defective piece I got.
