Brushless Motor Parameters
- Model and Size: The F2207.5 indicates that the stator diameter of the motor is about 22mm and the height is around 7.5mm. It belongs to a relatively compact motor type, which is suitable for aircraft like FPV racing drones that have strict requirements for motor volume and weight.
- KV Value: There are three options available: 1750KV, 1950KV, and 2550KV. The higher the KV value, the higher the rotational speed of the motor under the same voltage, but with relatively lower torque. Generally, it needs to be paired with smaller propellers. Conversely, a lower KV value means a lower rotational speed and higher torque, allowing it to be paired with larger propellers.Lean more…
Propeller Parameters
- Size: Two sizes of propellers, 10-inch and 5-inch, are provided for matching. Generally speaking, a 10-inch propeller can generate greater lift and thrust when rotating, but it requires more motor torque. Meanwhile, its larger moment of inertia may affect the maneuverability of the FPV racing drone. A 5-inch propeller generates relatively less lift and thrust, but with a smaller moment of inertia, enabling the FPV racing drone to be manipulated more nimbly and agilely.
- Material and Performance: Propellers are usually made of materials like plastic or carbon fiber. Plastic propellers are lower in cost and lighter in weight, but relatively weaker in strength and rigidity. Carbon fiber propellers, on the other hand, possess higher strength, rigidity, and better corrosion resistance. They can maintain good stability and efficiency when rotating at high speeds, though they are more costly.Get a Quote
Matching Recommendations
- F2207.5 – 1750KV Motor: Due to its relatively low KV value and higher torque, it is more suitable to be paired with a 10-inch propeller. Such a combination can ensure sufficient lift while allowing the motor to drive the propeller to rotate with less effort, reducing the motor’s burden and improving flight stability and efficiency. It is applicable to FPV racing drone flight scenarios where there isn’t an extremely high requirement for flight speed but certain demands for endurance and stability.
- F2207.5 – 1950KV Motor: With a moderate KV value, the choice of propeller can be based on the specific requirements and flight style of the FPV racing drone. If you pursue better maneuverability and flight speed, you can pair it with a 5-inch propeller. If you hope to obtain relatively greater lift and endurance while maintaining a certain level of maneuverability, you can also try pairing it with a 10-inch propeller, but it may be necessary to appropriately adjust the motor’s working voltage and flight parameters.
- F2207.5 – 2550KV Motor: With a relatively high KV value, it has a fast rotational speed but lower torque. It is recommended to pair it with a 5-inch propeller. This way, the high rotational speed advantage of the motor can be fully utilized, enabling the FPV racing drone to achieve a faster flight speed and better maneuverability. It is suitable for competitive FPV racing drone flights or scenarios where there are high requirements for flight speed and manipulation flexibility.
