The Futaba 14SG incorporates 2.4GHz FASSTest technology. It's also compatible with Futaba FASST and S-FHSS protocols, so you can fly with virtually any 2.4GHz air receiver Futaba produces. The 14SG can transmit and receive telemetry data. Install Futaba telemetry sensors (sold separately) to monitor flight data, receive alerts while in flight and more. Heli pilots will prefer the 14SG's 3-axis gyro support which makes the 14SG the perfect system for flybarless flight!
