Made for multiroter

Three Output Options.One Connector.
The AR7700 is compatible with many of the most popular flight controllers and gives users three connection options to choose from: Serial (SRXL), PPM and Remote Receiver. Just plug a single connector into the receiver port that supports the option you want to use and connect it to your flight controller.

Two AUX Ports And A Gear Port.
The AR7700 includes extra ports that let you run functions like retractable landing gear, lights or gimbal control directly from the receiver.

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.

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.

Broad Compatibility

The AR7700 will work with these and many other multi-rotor flight controllers.
