What Are Collective Pitch Drones (Detailed Answer)
Collective pitch drones, also known as CP drones, are a type of unmanned aerial vehicle (UAV) that use the pitch of their rotor blades to control lift and movement. This allows for greater control and maneuverability compared to fixed-pitch drones, which have rotor blades that are set at a fixed angle. In this article, we will take a closer look at what collective pitch drones are, how they work, and their various applications in detail.
The term “collective pitch” refers to the ability to change the pitch of the rotor blades collectively, rather than individually. This is achieved through the use of a mechanical linkage or an electronic control system, which allows the pilot to adjust the angle of the blades in real-time. By adjusting the angle of the blades, the pilot can control the amount of lift generated by the rotor, which in turn affects the drone’s altitude and speed.

What Is Fixed Pitch Technology?
Fixed pitch technology refers to a type of rotor blade design used in drones where the angle of attack of the blades is fixed and cannot be adjusted. This means that the angle of the blades remains the same throughout the flight, and the pilot cannot change it to control lift or movement.
In fixed-pitch drones, the lift is generated by the rotation of the rotor blades. The speed of rotation is controlled by the electronic speed controller, which adjusts the power to the motors to increase or decrease the speed of the rotors. This allows the pilot to control the altitude and speed of the drone, but it does not provide the same level of control and maneuverability as collective pitch technology.
Fixed-pitch drones are generally simpler and less expensive than collective-pitch drones, and they are also typically easier to fly and maintain. They are often used for basic aerial photography and videography, as well as for recreational and hobbyist use.
Fixed pitch technology is considered less versatile than collective pitch technology, as it lacks the ability to adjust the angle of the blades, which can limit its ability to perform certain tasks. It is generally used in small drones that are flown primarily for hobby or entertainment purposes, rather than for professional or commercial use.
