4000 Meters Control DistanceDSSS* 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 R12DS.4KM (2.5 Miles) * Range enables all possible RC fun.The 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 PWM Signals Output 12 channels. Detachable antennas. SBUS and PWM can operate simultaneously for seamless user control. Adaptable models include Rotary Wing, Fixed Wing, Glider, Multicopter, Car, Boat and Robot. Compatible with PIXHWAK, MINI PIX, TURBO PIX, APM, Byme-A and Byme-D flight controllers which support SBUS or PPM signal. Real-time Telemetry Real-time model data allows users to receive crucial information on the model's systems. When paired with flight module PRM-01, model voltage is displayed.
