In order to use larger propellers, either the motor Kv or battery cell count should be reduced.

Motor and Prop Size
 

Correct motor and propeller selection is very important to reduce the load on the ESC and to reduce motor saturation. Incompatible combinations can result in reduced overall performance, reduced system lifetimes due to excess heat and even ESCs burning out. If the prop and motor combination draw more than the ESCs nominal current rating at a static load, they are not recommended. For reference, a system running a 120F3 and a MAS 13x12x3 propeller should have the following motor Kv:

Cell Count

Recommended Kv

6S

500-700Kv

8S

400-600Kv

10S

350-450Kv

12S

300-400Kv

In order to use larger propellers, either the motor Kv or battery cell count should be reduced.

Drone propellers can be constructed with two, three, or four blades. Propellers with more blades provide greater lift due to more surface area moving through the air per rotation, but are more inefficient due to increased drag. Smaller drones with limited battery life are best suited to propellers with fewer blades.

Drone propeller blades are most commonly constructed from plastic or carbon fiber. Plastic propellers are cheaper and more flexible, allowing them to absorb impact better. The increased stiffness of carbon fiber propellers, although providing less durability, decreases vibration thus improving the flight performance of the drone and making it quieter. Carbon fiber is also lighter than plastic, allowing weight savings.
