The Radiolink R12DSM 12 Channel MINI Receiver is a powerful single line receiver with a range of up to 4KM (2.5Miles)

4000 Meters Control Distance

DSSS* and FHSS* hybrid spread spectrum, 16 channels pseudo-random frequency hopping, and QPSK* modulation ensures excellent anti-interference performance, highly constant, and stable transmission signal present on all 12 channels of R12DSM.
4KM (2.5 Miles) * Range enables all possible RC fun
Maximum PWM jitter is 1.84us with a standard of just 0.5us.

* Direct Sequence Spread Spectrum transmissions multiply the data by a "noise" signal. This noise signal is a pseudorandom sequence of 1 and -1 at a frequency higher than that of the original signal.
* Frequency Hopping Spread Spectrum offers three main advantages: signals are highly resistant to narrowband interference, are difficult to intercept and can share a frequency band with many types of conventional transmissions with minimal interference.
* Maximum range is tested in an unobstructed area free of interference.

SBUS and PPM Signals Output
R12DSM, 12 channels of SBUS/PPM signal output, detachable antennas, adaptable almost all of the flight controllers, is a great choice for a racing drone.
The super-lightweight of 2.5g and the small size of 30*15mm make R12DSM is tiny enough even for a mini racing drone.

Real-time Telemetry
Real-time telemetry RSSI information allow users to receive crucial information on the model's systems.
