What kind of electromagnet should be equipped with a petrol-powered model aircraft: hot topics and purchasing guide
Recently, oil-powered model aircraft enthusiasts have been discussing the matching of electromagnetic equipment (such as servos, receivers, etc.) heatedly. This article combines the hot topics and hot content on the Internet in the past 10 days to sort out the key points for purchasing electromagnetic equipment for oil-driven model aircraft and provide structured data reference.
1. Core requirements of electromagnetic equipment for oil-driven model aircraft
Due to the characteristics of large engine vibration and strong electromagnetic interference, oil-driven aircraft have higher requirements for electromagnetic equipment. Here are the top three needs that have come up in recent discussions:
| Requirement type | Specific instructions | Popular brands (recently discussed) |
|---|---|---|
| Anti-interference ability | Need to resist electromagnetic interference from engine ignition system | Futaba, FrSky, Spektrum |
| Seismic performance | Steering gears need to withstand high-frequency vibrations | Savox, KST, MKS |
| Response speed | Steering gear reaction speed affects control accuracy | JR Propo,Hitec |
2. Recommendations for popular electromagnetic equipment in 2024
According to forum and e-commerce platform data in the past 10 days, the following combinations have attracted the most attention:
| Device type | Model | Applicable scenarios | recent price range |
|---|---|---|---|
| receiver | Futaba R7008SB | Large oil-operated fixed wing | ¥800-950 |
| steering gear | Savox SC-1256TG | 50-120 level oil-driven model | ¥280-350/piece |
| Ignition system | Rcexl CDI Twin | twin cylinder engine | ¥600-700 |
3. Comparison of user measured data
The latest test data released by the aircraft model community shows:
| test items | Futaba system | FrSky system | Spektrum system |
|---|---|---|---|
| Anti-interference distance | 300 meters (no disconnection) | 280 meters | 250 meters |
| Servo delay | 0.08 seconds | 0.12 seconds | 0.10 seconds |
| Vibration damage rate | 2% | 5% | 3% |
4. Precautions when purchasing
1.Power matching: Oil-driven models are recommended to be powered by 6V-7.4V lithium batteries, and the voltage range of the electromagnetic equipment needs to be confirmed.
2.Installation protection: It is recommended to install a shock-absorbing sponge on the receiver, and the servo cable needs to be fixed with a tie.
3.Signal encryption: It is safer to choose a 2.4G system that supports FHSS or DSSS technology
4.After-sale guarantee: Give priority to brands that provide waterproof and oil-proof warranty services
5. Forecast of future trends
According to recent industry trends, electromagnetic equipment for oil-driven model aircraft will show the following development trends:
1. Popularization of intelligent diagnostic functions (such as Savox’s newly launched Bluetooth servo self-test system)
2. Composite material gear set replaces metal gears (reduces weight while maintaining strength)
3. Dual-band redundant communication system (using 2.4G and 900M frequency bands simultaneously)
From the above analysis, it can be seen that the selection of electromagnetic equipment for oil-driven model aircraft needs to comprehensively consider performance, price and reliability. It is recommended that players make a choice based on the specific model size and flight needs and refer to the latest measured data.
