Looks that way. On the page it says it takes any receiver that supports any of these protocols…
- Receiver Compatibility: SBUS / IBUS / DSM2 / DSMX / TBS / ELRS
You can get FlySky receivers that support both SBus and IBus. The normal one (FS-IA6B) supports both, although it’s kind of heavy for a drone. It looks like the most ideal would be the FS-X8B which is pretty light and supports RSSI.
PS, if you’re looking at FlySky Receivers, the FS-I6x supports AFHDS 2, but not 3, so avoid those.
