What receiver is used for F3 flight control? Analysis and recommendations of hot topics across the Internet
In the field of drones and model aircraft, F3 flight control is favored by players because of its high cost performance and stability. However, choosing the right receiver is still a point of confusion for many users. This article will combine the popular discussions on the Internet in the past 10 days to provide you with a detailed analysis of the receiver selection plan for F3 flight control and provide structured data reference.
1. Core requirements for F3 flight control receiver
According to recent hot discussions in forums and technology communities, the compatibility of the F3 flight controller with the receiver is mainly focused on the following three points:
1. Support PPM or SBUS protocol
2. The operating voltage range needs to match (usually 3.3V-5V)
3. Signal transmission stability (delay is better if it is less than 20ms)
2. Performance comparison of popular receivers in 2023
| Model | Protocol support | Weight(g) | Delay(ms) | reference price | Popular index |
|---|---|---|---|---|---|
| FrSky X4R | SBUS/PPM | 5.8 | 9 | ¥180 | ★★★★★ |
| FlySky FS-A8S | PPM/iBUS | 3.2 | 12 | ¥120 | ★★★★☆ |
| TBS Crossfire Nano | CRSF | 6.1 | 5 | ¥450 | ★★★☆☆ |
| RadioLink R6FG | SBUS/PPM | 7.5 | 15 | ¥150 | ★★★☆☆ |
3. Recommended solutions for different scenarios
1.racing drone: Give priority to TBS Crossfire series, ultra-low latency is the key
2.Entry level exercise machine: FlySky FS-A8S is the most cost-effective and supports PPM protocol
3.Professional aerial photography: FrSky X4R has the best stability and supports SBUS output
4. Top 5 hotly discussed issues among users recently
| question | Discussion popularity | solution |
|---|---|---|
| SBUS signal is unstable | 3285 times | Check flight control firmware version/replace wires |
| PPM protocol delay is too high | 2156 times | Upgrade to the latest Betaflight firmware |
| Insufficient power supply to the receiver | 1872 times | Install 5V BEC module |
| Binding failed | 1543 times | Reset receiver to factory settings |
| Short signal distance | 1328 times | Check antenna installation/replace high gain antenna |
5. Key points of installation and configuration
1. Wiring method: The SBUS receiver is usually connected to the UART port of the flight controller
2. Betaflight configuration: You need to enable the corresponding serial port on the Ports page and select the correct receiver type on the Configuration page.
3. Signal test: Be sure to conduct a 50-meter distance signal test before first use.
6. Forecast of future trends
According to recent discussions in overseas technology forums, ExpressLRS protocol receivers are becoming a new hot spot. Its advantages include:
- Open source firmware can be customized
- Theoretical latency can be as low as 2ms
-Supports 500Hz refresh rate
It is recommended to pay attention to new products such as Radiomaster RP1 and HappyModel EP1.
Summary: The choice of receiver for F3 flight control requires comprehensive consideration of protocol compatibility, usage scenarios and budget. At present, FrSky X4R is still the best overall choice, but new technologies such as ExpressLRS deserve continued attention. It is recommended that users check the specific model instructions of the flight controller before purchasing to ensure hardware compatibility.
