Holystone HS700E EIS 4K GPS Drone Flight Test Review

0 869

This upgrade to the HS700D now includes electronic image stabilization for stable and true 4K video without need of a mechanical gimbal. Find it here and use coupon RGPL6NZW for 10 percent savings https://amzn.to/3gWny6m

– True 4K video camera with 30 fps frame rate. Also can record 1080p video at 60 fps.
– Dedicated onboard processor for electronic image stabilization. Works reasonably well to stabilize video without the need for a mechanical gyro stabilized gimbal.
– GPS for stable hovering and automatic return to home and landing on command, loss of signal, and low battery. Low battery brings the drone to hover over the takeoff point, but will allow further flight within 100 meters of takeoff point until battery depletion (at which point it lands wherever it’s at).
– Optical flow sensor for automatic hovering indoors, or outdoors if so desired.
– Bright belly LED lights for improved visibility, especially at dusk.
– Brushless motors.
– 7.4V 2800mah provides 21 minutes of flight time.
– FPV range of up to 500 meters, and controller range of up to 1,000 meters.
– Real time FPV video is available through your phone using the “Ophelia GO” app available on Google Play here https://bit.ly/Ophelia-GO or for iOS here https://bit.ly/Ophelia_GO
– App also provides advanced capabilities of follow me, orbit position, waypoints, and headless mode. App also enables modifications of video and photo settings including resolution, brightness, saturation, special effects, ISO, and white balance.
– Drone can be flown without the app using just the controller if desired. Controller includes telemetry information screen providing drone and controller signal strength, remaining battery power, drone distance and height, GPS status, flight rate, and controller mode. Controller also provides buttons for automatic takeoff and landing, lights, camera pitch, photo and video shutter, return to home, arm and disarm motors, and GPS on or off.

– The app requires use of a phone with 802.11ac WiFi. Before purchasing, use Google to verify that your phone does indeed have 802.11ac WiFi (not everybody has such on their phone).
– The drone’s low rate is very slow in both horizontal speed and yaw (turning) rate. The intent is to aid processor image stabilization.
– Electonic video stabilization works reasonably well. But there are a couple of limitations. First is that the stabilization does result in slight blurring of the video. The second is that the EIS has difficulty in keeping the video horizon level. This is especially true if there is wind that will cause the drone to maintain a tilt to counter the wind. The resulting tilt of the drone will be apparent in the video view of the horizon.
– Requires using at least a Class 10 SD card for 1080p 60 fps video, and at least a U3 SD card for 4K video. Expect severe frame dropping if you attempt to use a slower speed card.
– Weighs 559 grams with battery, and requires registration in most countries.
