• It lacks control and spins undesirably.

• It cannot generate enough lift.

• It consumes too much energy.

How do two-propeller drones avoid undesirable body spin?

• By increasing the number of propellers.

• By rotating the blades in the same direction.

• By using larger propellers.

• By rotating the blades in opposite directions.

What shape do quadcopters typically have?

• Triangular

• H-shape or X-shape

• Circular

• Rectangular

How is a quadcopter's yaw motion achieved?

• By increasing the speed of all propellers.

• By using larger propellers.

• By reducing the speed of one diagonal pair of propellers.

• By tilting the drone body.

What is the primary function of a drone's flight controller?

• To provide power to the drone.
