Product overview
The RadioLink R8SM is a miniature eight-channel receiver intended for racing drones and multicopters, with its compact format also suited to mini racing drones and gliders. Its 18 × 13 mm dimensions and 2 g weight provide a small integration footprint. It delivers eight channels through SBUS or PPM, allowing connection to compatible flight controllers. The receiver uses FHSS spread spectrum with 67-channel pseudo-random frequency hopping to help reduce signal interference, and has a stated control distance of 2000 meters.
Integration requires a 3–10 V supply and a compatible RadioLink transmitter. Listed transmitter options include RC8P, T16D, T12D, T8S and T8FB, alongside the specified RC6GS and RC4GS versions. The receiver interface is 3P ph1.25, with the connection arrangement showing a soldered signal connection at the flight controller. The supplied configuration comprises one R8SM receiver, one connection cable and one packing bag. This is a receiver component package for installation in an aircraft, rather than a complete flight platform or an airframe kit.
