Radiomaster R81 V2 Nano Receiver

Overview:
The RadioMaster R81 V2 Nano is a compact, 8-channel receiver which supports FrSky D8, D16 and Futaba SFHSS protocols, and transmits SBUS with RSSI feedback — making it a versatile choice for lightweight multirotors, fixed-wing models and minimal-weight builds. Despite its nano form factor it offers a control range of over 1km in open conditions, making it both a reliable and space-saving option for a variety of RC applications.

Features:
- Full 8-channel SBUS output for rich control and compatibility with modern flight controllers. 
- Supports FrSky D8, D16 and Futaba SFHSS protocols via multi-protocol or MPM radios. 
- EU-LBT regulatory compliance ensures legal operation in Europe. 
- RSSI fed back on channel 9 of the SBUS signal to help with telemetry or signal strength monitoring. 
- Lightweight 2g design fits cleanly into tiny or tightly-packed frames. 
- Small footprint (17×11mm) helps preserve space for other components in compact builds. 
- Long antenna (60mm) gives good reception without significantly increasing size.
