7-channel DR receiver The small, universal 7-channel receiver in MULTIPLEX 2.4 GHz M-LINK technology. As a dual receiver, it has two complete, parallel-working receive channels (receiver diversity) in spite of the small size, thus ensuring very good reception quality. The RX-7-DR light M-LINK is particularly suitable for smaller models due to its low weight and small dimensions. The inline connector arrangement, as well as the compact design, allow the use in slim fuselages (eg F3B, F3J, ...).
