Motor and Prop Size

Summary

Correct motor and propeller selection is crucial for reducing the load on the ESC and minimizing motor saturation. Incompatible combinations can lead to reduced performance, shortened system lifetimes due to excess heat, and potential damage to the ESCs.

Key Points

• A system running a 120F3 with a MAS 13x12x3 propeller should have the following motor Kv based on cell count:

- **6S**: 500-700Kv - **8S**: 400-600Kv - **10S**: 350-450Kv - **12S**: 300-400Kv

• To use larger propellers, either reduce the motor Kv or the battery cell count.

Propeller Construction

Summary

Drone propellers can be constructed with two, three, or four blades. The choice of material can be plastic or carbon fiber, each with its own advantages and disadvantages.

Key Points

• Blades: More blades provide greater lift but are less efficient due to increased drag. Smaller drones with limited battery life are best with fewer blades.
• Materials:

- **Plastic**: Cheaper, more flexible, better at absorbing impact. - **Carbon Fiber**: Stiffer, less durable, reduces vibration, quieter, lighter.
