Graupner GR-18AIR 9 Channel 2.4GHz HoTT Receiver and Airplane/Helicopter Flight Controller
Brand: Graupner

Engineered with an integrated flight controller for 3-axis airplane flight control and a flybarless controller for helicopters the GR-18AIR provides 9 control channels for Graupner 2.4GHz HoTT radios. The GR-18AIR is a long-range receiver with diversity antennas using the Graupner HoTT protocol to provide real-time telemetry data of signal strength receiver voltage and temperature all to assist you during flight to enhance situational awareness and safety. Setting up an airplane or helicopter model or telemetry values is done directly from your HoTT radio, wireless over the air. No computers or programming boxes are needed! Need to make a change to the receiver or gyro settings? Simply land and make on-the-spot changes at the field or you can assign a control to do so even in the air during flight! The GR-18AIR can be expanded with additional telemetry modules (GPS, OSD, ESC, Vario Telemetry, etc.) for continual improvement of your system’s reliability and performance. The GR-18AIR can also be used as a regular 9 channel receiver when the gyros are switched off (default)

Airplane Mode: three axes gyro stabilization with remote gain/deflection control
Helicopter Mode: Flybarless controller with remote gain control
Ultra-fast gyros and accelerometer sensors for fast and crisp response
Built-in telemetry for signal strength, temperatures and receiver voltage
Optional SUMD digital serial output
