RATEFPV W20 2" Freestyle With ELRS Receiver

Version Update Notice

As the official O4 version has been officially upgraded to the new O4 Wide version, the old W20 O4 version has been removed from our store shelves on 2026.7.20.
To meet diverse user needs, we provide two optional solutions:
1. For the latest official upgraded performance and features, please purchase the newly launched W20 O4 Wide version;
2. If you still need the original classic O4 Lite version, you can buy the W20 No O4 Lite Unit version and install the O4 Lite module by yourself.
This version upgrade only optimizes and iterates the adaptation module with overall improved core performance and user experience.
