FrSky R9 MM

5 8

Teeny tiny Rx with a huge 6+ mile range.

  • The newly released R9MM receiver is pretty darn small and retains the majority of the features of the R9 Mini. It still has super low latency, high precision and a very low mass. The most important new feature is that the S-Bus port has been inverted to make the R9MM compatible with a wider range of external devices.
