i dont think the drone can freefall , because of the air pressure on that height and the speed will make the propellers automatically spin which means there will be some thrust , but if its a CWW propeller then the thrust would be opposite to the side its falling which will make it fall faster as the drone is falling down while the thrust is going upwards.
It has autorotation which is a physical rotation of the blades without power in case of emergency landings seen in helicopters. You might want to use a blade gaurd as well because its the blades that provide the upthrust for the entire drone.
Bhai Mera drone bhi 50/60 mtr ko baad najar nahi aaya control bhi nahi kar paya drone 4drc v9 kaha tak ja sakta hey oh drone tesri manjil height ma uhdraha tha Hum hogaya usme mobile conect bhi nahi kiya tha first trial mehi gum hogaya kếse milega kitna range gems dhudna padta hey
