This is a small, multi-purpose seven-channel receiver using Multiplex's 2.4GHz M-LINK technology. It is a dual receiver, featuring two complete receiving circuits operating in parallel (receiver diversity), ensuring excellent reception quality despite the receiver's small dimensions.The RX-7-DR light is a particularly good choice for the smaller model as it is so light and compact. The in-line connector arrangement and compact case design make it suitable for installation in slim glider fuselages and perfect for F3B, F3J and more.
