WLToys Q393A Dragonfly FPV Drone Flight Test Review

The Q393A includes 5.8 Ghz FPV, altitude hold, 720p camera, up-down remote lens, and telemetry. Find it here 18% off with coupon rc18off https://goo.gl/NixN6R

Pros
– Includes a dampened camera mount. Camera lens can also be remotely controlled up and down.
– Telemetry of battery power, altitude, and velocity. Altitude info from onboard barometer, and velocity info seems to be calculated from the accelerometers.
– Includes a 720p HD camera with SD card and USB card reader. The camera produces relatively good video for a 720p camera.
– Also includes 5.8 Ghz FPV transmitter and receiver/monitor. FPV transmits on 5.8 Ghz analog band E4 (5645 Mhz), so FPV goggles can be used if unsatisfied with provided FPV monitor.
– Total flight time from the 2600mah battery was 7 minutes 18. This was the battery’s first flight, so it hasn’t been conditioned yet.
– Automatic takeoff and landing.
– Headless mode and one key return.

Cons
– Plenty of video jello. Props will need balancing to reduce. Here’s how https://www.youtube.com/embed/-vakWrc86xE
– Brushed motor quadcopter. Will eventually require replacement of motors.
– One key return is standard toy grade return (backwards parallel flying of takeoff heading), and is NOT a true return to home and landing.
– Telemetry battery power is somewhat inaccurate. Also very little time between low battery warning beep and automatic descent of quadcopter. But the quadcopter does descend to a landing on low battery (doesn’t fall from the sky like a brick).
– Over 250 grams. Will require FAA registration in the USA. It takes $5 and 5 minutes to get it here https://registermyuas.faa.gov/
