Multiplex Receiver Rx-9-Dr Compact Ml 2.4 G 55820

The Multiplex Receiver Rx-9-DR Compact M-LINK 2.4G (MPX55820) delivers top-level performance in a slim, lightweight format. Aimed at discerning glider pilots flying F3B and F3J models, it shares the same core technology as the brand’s pro-series receivers, including dual receive sections and high-performance signal pre-amplifiers for outstanding security and control fidelity.

With nine channels, robust telemetry, and a broad operating voltage range, this RX-9-DR compact unit is designed for reliable operation in high-demand sailplane and performance applications while keeping installation neat and efficient.

Key Features

• Ultra-compact dual receiver with 9 channels
