What remote controller is suitable for connecting to F4 flight controller?

With the popularity of drone technology, F4 flight control has become the first choice of many pilots due to its high performance and stability. However, choosing the right remote control is crucial to your flying experience. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the types of remote controllers suitable for F4 flight control connection, and provide structured data reference.

1. Introduction to F4 flight control

F4 flight control is a flight control system developed based on the STM32F4 series microcontroller and supports multiple protocols and function extensions. It has strong compatibility and can be adapted to a variety of remote controls, but attention must be paid to protocol matching and performance requirements.

2. Analysis of popular remote control types

According to recent discussions, the following are common remote control adaptation solutions for F4 flight control:

3. Key factors in choosing a remote control

1.protocol matching: F4 flight control usually supports SBUS, iBUS, PPM and other protocols. It is necessary to ensure that the remote control output protocol is consistent.

2.channel requirements: Racing drones require at least 5 channels (throttle, roll, pitch, yaw, mode switching), and 8 or more channels are recommended for FPV flight.

3.Scalability: Remote controls that support Crossfire or ELRS protocols are more suitable for long-distance flights.

4. Recent hot topics of discussion

1.The rise of ELRS protocol: ExpressLRS (ELRS) has become a popular choice in 2023 due to its low latency and high reliability, and requires a dedicated receiver.

2.Open source system advantages: Remote controls of EdgeTX/OpenTX systems (such as RadioMaster) can implement advanced functions through scripts.

3.Cost-effectiveness battle: FlySky FS-i6X provides 10-channel output at a price of 200 yuan, making it the first choice for entry-level speakers.

5. Comparison of specific connection solutions

6. Precautions

1. Some F4 flight controllers need to configure the protocol type through Betaflight, and the firmware version needs to be checked before connecting.

2. When using the PPM protocol, the number of channels is limited and the delay is high. It is recommended to give priority to the digital protocol.

3. Multi-protocol remote controls need to pay attention to module power settings to avoid signal interference.

7. Summary

The selection of remote controller for F4 flight control should comprehensively consider the budget, flight scenarios and technical requirements. Current market trends show that open source remote controls supporting the ELRS protocol are becoming the mainstream choice, while traditional brands such as FrSky still maintain their advantages in the mid-to-high-end market. It is recommended that users refer to the data in this article to make decisions based on actual needs.
