Recommended Settings:

To achieve precise control at low RPMs and outstanding power at full throttle, Chris Rosser recommends using throttle expo in Betaflight:

• Throttle MID: 0
• Throttle EXPO: 0.20 (can be adjusted for increased precision at low RPMs or sharper response)

Applications:

The AOS Supernova 2207 1570KV is an ideal choice for pilots looking for top performance in their 5" FPV drones powered by 8S batteries.
It offers an excellent combination of thrust, torque, and efficiency, making it suitable for both freestyle flying and racing applications.

With this motor, you not only get high performance but also the reliability and precision needed for demanding FPV flights.

Potential Use in Larger Drones:

7" Long-Range FPV Drones:

• Thanks to its high torque and efficiency, these motors can also be used in lighter 7" drones, particularly in configurations focused on endurance and flight efficiency.
• Motors with a low KV rating (1570KV) combined with larger props and lower RPMs can offer extended range and better energy efficiency when using an 8S battery.

Cinematic Drones (6–7 inches):

• For lightweight camera platforms aimed at smooth motion and filming in environments with lower speed requirements, these motors can provide stable flight characteristics.
• The lower KV ensures smoother transitions and better drone control at low RPMs.

Prototype and Experimental Drones:

• Developers and FPV enthusiasts can utilize these motors to test various configurations of larger frames that require high power while maintaining reasonable weight.

Ultralight 6" Freestyle Drones:

• If agility and longer flight times are the priority, these motors can be used in lightweight 6" freestyle drones, offering better power reserves and control.

Limitations of Using on Larger Drones:

• Thrust vs. Weight:
  On heavier drones, the thrust may be limited, which could affect flight dynamics and maneuverability, especially during aggressive moves.

• Efficiency:
  When used with larger props (e.g., 7–8"), efficiency may decrease, leading to higher power consumption and shorter flight times.

• Thermal Load:
  Larger frames and higher weights may cause increased motor heating under heavy load conditions.

Conclusion:

The AOS Supernova 2207 1570KV motors can be used in larger drones when a lightweight setup with a focus on efficiency and control is desired.
However, for more demanding applications on heavier drones, it is recommended to choose motors with a larger stator (e.g., 2306, 2507), which can better handle higher loads and larger props.
