See all of our FrSky Products and all of our Receivers!
Unlock incredible long-range performance and next-generation features with the FrSky R9 MM-OTA, a compact 900MHz receiver built on the powerful ACCESS protocol. This tiny receiver is designed for FPV drone pilots seeking a more robust and reliable control link over extreme distances. With innovative features like over-the-air updates, it’s a smart and powerful choice for your long-range FPV drone.
True Long-Range Performance
The R9 MM-OTA operates on the 900MHz frequency band, which provides significantly better range and signal penetration through obstacles like trees and buildings compared to standard 2.4GHz systems. This makes it the ideal choice for long-range exploration, mountain surfing, or any FPV drone flight where a rock-solid link is absolutely critical.
OTA for Ultimate Convenience
The “OTA” (Over-The-Air) feature is a game-changer for builders. With a compatible FrSky ACCESS transmitter, you can update the receiver’s firmware wirelessly, without ever having to physically access or plug into the receiver. This is incredibly convenient, especially when the receiver is installed deep inside a complex FPV drone build.
Key Features:
- 900MHz Long-Range Link: Provides significantly better range and signal penetration through obstacles compared to 2.4GHz systems.
- ACCESS Protocol: A powerful and feature-rich protocol from FrSky offering a secure and reliable link.
- OTA (Over-The-Air) Updates: Wirelessly update the receiver’s firmware with a compatible transmitter, eliminating the need to physically access it.
- Full Telemetry Support: Supports S.Port (and F.Port with firmware update) to send vital flight data like battery voltage and GPS coordinates back to your radio.
- Micro Size & Weight: At only 0.7g, it adds incredible long-range capability without a significant weight penalty, perfect for any size FPV drone.
- Detachable Antenna: Uses a standard Ipex1 (U.FL) connector, allowing for easy antenna replacement or upgrades.
