Can a one propeller drone work efficiently for a good flight and stable camera footage in a drone flight

$\begingroup$ Have you seen any drone that flies with solely one propeller? The reason behind this is the stability issue. You can't stabilize this configuration of drones. Always remember instability with unmanned aerial vehicles means crash. On one is willing to build such a complicated system and then let it crashes. $\endgroup$– CroCoNov 7, 2015 at 23:10

$\begingroup$ How about two propellers? I saw a video with two propellers.Helicopters fly with one propeller.I have seen a video with one propeller and it was good at functioning $\endgroup$– sohaib shaikhNov 7, 2015 at 23:16

$\begingroup$ Helicopters have tails. $\endgroup$– CroCoNov 7, 2015 at 23:20

Helicopters are a quasi-single propeller drone, but they require a tail propeller to counter-act the effects of the lift propeller. Due to newton's third law of motion, the lifting propeller's spin in one direction will cause the the body of the helicopter to spin in the other direction. Without a tail propeller to overcome this effect, A single motor drone would simply spin out of control.

2$\begingroup$ Nonsense, there are lots of 1-motor, 1- propeller drones that fly perfectly well. Eg see Ultimate 45CC-50CC Giant Scale Radio Remote Controlled RC Bi-Plane $\endgroup$ Nov 8, 2015 at 19:50

1$\begingroup$ @jwpat7, we refer to Rotary Wing Aircraft since the OP mentions in his comment the helicopters. $\endgroup$– CroCoNov 9, 2015 at 0:33

$\begingroup$ @CroCo, the CQ-10 Bravo (Canadian Gyroplane Cargo Carrier Unmanned Aircraft) appears to be a 1-motor, 1- propeller drone when in forward flight. The top prop (the autogyro rotary wing) is powered for vertical take off. See photo and notes, about 1/4 of the way down the page $\endgroup$ Nov 9, 2015 at 21:07

$\begingroup$ @jwpat7, but it has two propellers. As I said, another problem with one propeller is the maneuverability. Under very restricted conditions, you could build a drone with one propeller but it flies vertically and with few centimeters if not millimeters until it crashes. This is not an efficient drone, not even sufficient. $\endgroup$– CroCoNov 9, 2015 at 21:34

2$\begingroup$ @sohaibshaik: a cursory google search reveals no such single motor drone. You claim that it exists... Prove it by posting a link. $\endgroup$– PaulNov 13, 2015 at 20:58
