Overall the XK X300 has become one of my quadcopters to fly, the position hold works great with the optical flow sensor and the altitude hold holds height pretty good.

Flight times are great at around 13-15 minutes and the camera records some decent video with no video jello. The FPV has a pretty clear pictures with only small amounts of signal loss (static) and a very small (maybe 200ms max) latency.

Position hold works better with surfaces that have a slight pattern and something like a solid sheet of snow won’t hold position very well.

As I said at the beginning this is one of my favorite quadcopters and I’m pretty happy with it.

XK X300 F Long Flying Position Hold FPV Drone Review

1485893017_hqdefault.jpg




This very long flying quadcopter includes a position hold system that allows it to hover motionless without pilot inputs. Also includes altitude hold and 5.8 Ghz FPV. Find it here https://goo.gl/uFv5PH and here is the cheaper WiFi version https://goo.gl/EUcE3T

Pros
– 2000mah battery gives it a very long flight time of over 15 minutes.
– Optical position hold in combination with an effective altitude hold systems provides an almost motionless hover. Good for new fliers trying to learn the basics of quadcopter control.
– 720p camera provides relatively good video. External add-on cameras are not really needed with this quadcopter.
– Includes 5.8 Ghz FPV transmitter and receiver. Provides relatively long range FPV video in excess of 100 meters.
– Although I didn’t fly it past its range limits, the transmitter also allowed flying out past 100 meters.
– Powerful brushed motors (I think that they’re Tarantula motors). Motors provided very sporty flying ability limited only by the altitude hold system (which unfortunately can’t be turned off).
– Also includes headless mode (and I apologize that I forgot to demonstrate it).

Cons
– The optical position hold works very when starting from a slow flight speed. But the position hold becomes less effective if the initial speed of the quadcopter is increased. It could “slide” quite a distance before slowing sufficiently to allow the position hold system to take over. Position hold also becomes less effective as altitude is increased, and is ineffective above 8 meters.
– Weighs more than 250 grams, will require FAA registration if flying in USA.
– It does have an automatic takeoff and landing button. Unfortunately mine did not appear to be operational.

Hubsan H501C GPS Camera Drone Flight Test Review

1472670670_hqdefault.jpg




This new version of the popular H501 GPS camera quadcopter is up to $100 cheaper than the H501S version. Yet it still has the same airframe, brushless motors, 1080p camera, GPS position hold, telemetry, and return to home and landing capability. Buy it here http://shrsl.com/?dpkd

Pros
– Powerful brushless motor quadcopter at a reasonable price. Price reduction achieved by elimination of FPV and follow me capabilities of the H501S.
– GPS position hold flying.
– Return to home and automatic landing capability at takeoff point. Returns to home automatically on loss of signal from the transmitter, or if manually initiated by the return to home button.
– Transmitter is not a battery eater like that of the H501S. You’ll get many flights out of a set of batteries with this transmitter (I’m still going strong with more than a dozen flights).
– Great transmitter. I’ve flown it out to 300 meters before losing sight of the quadcopter forced me to turn back. But I still had control of the quadcopter throughout that flight.
– Transmitter includes telemetry information of quadcopter’s directional heading, distance, height, satellites received, and quadcopter remaining battery power.
– Very portable. Just the right save to take on a trip or on an airplane.
– Relatively quiet and non-intrusive in flight. Should be able to fly this in many places without being hassled.
– 1080p full HD camera.

Cons
– Does not have the FPV or follow me capability of the H501S. These capabilities were removed in the H501C to greatly reduce the cost of this quadcopter.
– Still weighs more than 250 grams, and will require FAA registration.
