A quadcopter, also called a quadrotor helicopter or quadrotor, is a multirotor helicopter that is lifted and propelled by four rotors. They are usually drones or UAVs that are used for various purposes.

Due to their small size, quadcopters are cheaper and more durable than conventional helicopters due to their mechanical simplicity. Their smaller blades are also advantageous because they possess less kinetic energy, reducing their ability to cause damage.

Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counter clockwise. These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust; to locate for the centre of thrust both laterally and longitudinally; and to create a desired total torque, or turning force.

Propellers are a part of the quadcopter that works like the wings of the machine and make the flight a lot easier. Buying a new set of propellers for your drone can actually change a lot of factors including the speed of the drone.

Here are some of the factors you must consider before purchasing a set of propellers for your quadcopter drone.

Since the propellers generate thrust and torque to keep the quadcopter flying it is essential that you invest in high quality propellers.

A drone has two different types of propellers and motors. One set is designed to spin clockwise, while the other is designed to spin counter clockwise. Be sure to identify which ones are which.

Another important factor to consider is the size of the propellers. According to experts, the size of the propeller is the distance from tip to tip. Longer propellers can generate more thrust at the same speed, but requires more torque from the motor to turn the propellers.

The propellers should not overlap since that can reduce the efficiency of the propeller. The number of blades on a propeller can also make a difference in its performance. Two bladed propellers are more efficient when compared to three or four bladed ones. The material with which the propeller is made is also important. The two materials available are plastic and carbon fibre. Recreational drones usually use plastic propellers which react better to crashes. However, the carbon fibre propellers are sturdier but can be more expensive when compared to the plastic propellers.

The weight of propellers can affect flying. Buying propellers that are lightweight is a good idea since they are better for faster flights. Buying a set of propellers that actually fits your quadcopter is very important so it is essential to check the sizing of your drone.  We hope you find the best set of propellers for your quadcopter.
