Access to All Your Channels

When using the SRXL and Remote Receiver connections, the AR7700 will allow you to tap into as many channels as your transmitter can support. The PPM connection can support up to 8 channels.

Remote Receiver Included

A small remote receiver is included for larger multi-rotor applications that could use the redundancy and path diversity of patented MultiLink™ technology. By mounting the remote receiver away from the main receiver with a different antenna orientation, the odds of experiencing signal fade from signal reflection or antenna polarization are substantially reduced.
