Hawk 18 HoTT - 2.4 GHz receiver

With the Hawk 18, Graupner presents a powerful 9-channel receiver with integrated 3-axis gyro and particularly vibration-resistant 3-axis acceleration sensor, diversity antennas, vario and attitude mode for fixed-wing models or rescue mode and attitude mode for helicopters.

With GRAUPNER HoTT 2.4 GHz technology, the receiver has a secure hopping telemetry transmission high-frequency section with high-quality components and state-of-the-art software. The receiver transmits the parameters "receiver voltage", "receiver temperature", "signal strength", "altitude", "altitude difference (vario)" to the transmitter without additional sensors. It is also possible to transmit the Euler angles to the transmitter and display them there.

The antenna amplifier together with the antenna diversity ensures an enormous range. The faster 32-bit L4 processor guarantees energy-saving operation and the higher performance ensures that the Hawk 18 can also be used as a flybarless system for helicopters and as a flight controller for copters. Of course, the integrated Hawk gyro system can also be used perfectly for fixed-wing models. There are 4 different gyro modes: OFF, normal stabilization, heading lock, gyro rate mode and attitude mode. When set correctly, the gyro rate mode enables knife-edge flight and torquing without control corrections. Extremely quick, easy and convenient to set via the Hott transmitter telemetry menu.

Just like its namesake, the falcon, the Hawk 18 embodies determination, power and precision. Go on the hunt for the perfect flight with the Hawk.

Wing models

•     Stabilization of the flight model in difficult wind conditions for up to 3 axes
•     Natural flight behavior due to proportional gyro fade-out
•     The 3-axis gyro allows even difficult-to-handle aerobatic models to be flown very smoothly and makes aerobatics extremely easy
•     Flight figures can be flown much more cleanly
•     4 different gyro modes: OFF, normal stabilization, heading lock, turn rate mode for particularly easy knife-edge flight and simple torquing as well as attitude mode
•     Simple setting of the gyro assignment
•     Parameter setting via HoTT telemetry
•     Software with attitude mode enables easy landings even in difficult wind conditions
•     5 free mixers
•     SUMD output for connection to flybarless systems, flight controllers or a power box.
•     SUMDIN input for redundant receiver operation.

Flybarless system for helicopters

•     Rescue mode and attitude mode for helicopters
•     Basic setting completed in a few minutes via HoTT telemetry
•     Fast and innovative axis assignment for flexible installation direction
•     Extremely space-saving due to size, weight and elimination of cables, making it easy to store
•     Special vibration-resistant 3-axis sensors of the latest generation
•     Swashplate pirouette optimization and direction of tail torque compensation are detected automatically
•     All common heli swashplates 90/120/135/140 degrees and 90 degrees 4 servos
•     Adjustable swashplate rotation up to 90 degrees for multi-blade heads
•     Clear standard menu and selectable expert menu if required
•     Sensitivity parameters can also be adjusted during flight to speed and style depending on flight phase via encoder
•     Super-fast due to elimination of transmission time from receiver to flybarless system
•     Very direct control feel

Programming for helicopters

•     Simple programming of the basic settings via telemetry.
•     Pirouette optimization is determined automatically from the parameters and works extremely well.
•     Extreme flight stability with full 3D capability even with the basic settings.
