What kind of motor is used in remote control aircraft: comprehensive analysis and purchasing guide
With the popularity of remote control aircraft (drones, model aircraft), motors are the core power components, and their selection directly affects flight performance. This article combines hot topics on the Internet in the past 10 days, from motor types, parameter comparisons to applicable scenarios, to provide you with a structured data guide.
1. Common types of remote control aircraft motors

At present, mainstream remote control aircraft motors are mainly divided into the following three categories:
| Type | Features | Applicable scenarios |
|---|---|---|
| brushed motor | Simple structure, low cost, but low efficiency | Entry-level toy drones, small model aircraft |
| Brushless motor | High efficiency, long life, requires matching ESC | Racing drones, professional model aircraft |
| Coreless motor | Light weight and fast response, but limited power | Micro drones, indoor aircraft |
2. Comparison of key parameters (taking brushless motors as an example)
According to the recent data analysis of hot-selling models on e-commerce platforms:
| Model | KV value | Maximum power | weight | price range |
|---|---|---|---|---|
| T-Motor F40 Pro | 2400KV | 600W | 32g | ¥200-250 |
| EMAX ECO 2306 | 1700KV | 480W | 28g | ¥150-180 |
| Racerstar BR2205 | 2600KV | 550W | 30g | ¥120-150 |
3. How to choose a motor according to your needs?
1.Aircraft type matching:
- For 5-inch racing machines, it is recommended to choose 2207-2306 size motors
- 3 inch cinewhoop recommended size 1404-1507
2.The relationship between KV value and propeller:
KV value × voltage ≈ theoretical speed, which needs to match the blade size:
- High KV (3000+) with small paddle (less than 3 inches)
- Low KV (below 1500) with large paddle (more than 5 inches)
3.Recently popular configuration solutions(from forum discussion):
| Application scenarios | Recommended motor | Typical configuration |
|---|---|---|
| FPV racing | T-Motor Velox V2 | 2207 1950KV + 5043 propellers |
| aerial photography drone | DJI 2312E | 2312 960KV + 1345S propeller |
| indoor stunt machine | BetaFPV 1103 | 1103 8000KV + 40mm propeller |
4. New trends in motor technology in 2023
1.Magnetic steel technology upgrade: N52SH and other high-grade magnets are popularized to increase torque density.
2.Thermal design optimization: The recently released iFlight XING2 adopts a hollow yoke design
3.Lightweight trend: New carbon fiber rotor is 30% lighter than traditional metal
5. Maintenance and troubleshooting
According to maintenance community statistics:
- 70% of motor failures are caused by bearing damage
- 15% short circuit due to water ingress
- Regular cleaning and adding bearing oil can extend the life by 2-3 times
Conclusion:Choosing a remote control aircraft motor requires a comprehensive consideration of aircraft size, performance requirements, and budget. It is recommended that novices start with mainstream configurations and refer to the comparison data in this article to avoid waste caused by blindly pursuing high parameters.
