Great drone for beginers
Advantages: Not to speedy, short flight time, camera with no sd card slot (it records directly to phone). Definitely need to buy more batteries.
Limitations: RTH works, telemetry works, it returns to home when the battery level its to low, wehen it losts signal from controler. Easy to calibrate (same as dji phantom). Great information in aplication and controler. Did not try the inteligent flight mods. Photo taken with drone camera in flight.
