One should consider the following parameters:
1. **Propeller diameter.** Larger propellers require more power of the motor for spinning. Make sure that the motor can develop the required power. Large and heavy propeller cells to have more inertia, therefore they cannot accelerate instantly, which will affect the copter's maneuverability.
2. **Prop pitch.** It is indicated by the second digit after "x" in the propeller brand; it may also be indicated by the third and the fourth digits of the brand - e.g., 1260 are propellers with the pitch of 6.0 inches. Physically, it is the air column that the propeller moves downwards in one revolution. The larger the pitch, the greater the lifting force. Naturally, there are reasonable limits: for example, 14х7 propellers have greater lifting force than 14х5 propellers. By the way, for the ideal case, the pitch of the propeller multiplied by the number of revolutions per second gives the speed of the air flow from the propeller.

3. **The number of blades.** In the classic case, there are two blades. However, propellers with three blades have greater lifting force - roughly equivalent to that of a two-blade propeller with the diameter 1 inch larger and the pitch 1 inch greater.
4. **Propeller constant**, the so-called Prop-Const, strongly affects the lifting force and the power of the motor required to spin the propeller, because physically this constant indicates the magnitude of the losses for air resistance during propeller rotation: the thinner the material the propeller is made of, the smaller this constant, and the smaller the power of the motor required for spinning the prop.
