What receivers does X9D support?
In the field of drones and remote control models, FrSky X9D is a classic remote control that is favored by users for its strong compatibility and flexibility. This article will introduce in detail the types of receivers supported by X9D, and attach hot topics and content from the entire network in the past 10 days to help users better understand equipment matching and industry trends.
1. Receiver types supported by X9D

FrSky X9D remote control mainly supports the following receiver protocols and models. Users can choose the appropriate receiver according to their needs:
| protocol type | Receiver model | Features |
|---|---|---|
| ACCST D16 | X8R, X6R, X4R, XSR | Supports 16 channels, high stability and compatibility |
| ACCST D8 | D8R-II Plus, D4R-II | Supports 8 channels, suitable for small UAVs |
| ACCESS | R9MX, R9MM, R9Slim+ | Support long-distance communication, suitable for FPV |
| SBUS | All receivers that support SBUS output | Simplify wiring and support series connection of multiple devices |
2. How to choose a suitable receiver
1.Choose an agreement based on your flight needs: If long-distance communication (such as FPV) is required, it is recommended to choose a receiver with the ACCESS protocol; if it is a regular flight, the ACCST D16 or D8 protocol can meet the needs.
2.Number of channels: 16-channel receivers such as X8R are suitable for complex models, while 8-channel receivers such as D4R-II are more suitable for small UAVs.
3.Dimensions and weight: Micro receivers (such as XSR) are suitable for weight-sensitive small drones.
3. Hot topics on the Internet in the past 10 days
The following are recent hot topics in the field of drones and remote control models for reference:
| topic | heat index | Main content |
|---|---|---|
