Hawk 18 HoTT receiver with 3-axis gyro and vario

GRAUPNER Hawk 18 HoTT receiver with 3-axis gyro and vario (9-channel)

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" and "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.

Together with the antenna diversity, the antenna amplifier 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 stabilisation, heading lock, rotation 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 hawk, the Hawk 18 epitomises determination, power and precision. Go on the hunt for the perfect flight with the Hawk.

Wing models

    Stabilisation of the flight model in difficult wind conditions for up to 3 axes
    Natural flight behaviour thanks to proportional gyro blanking
    The 3-axis gyro means that even difficult-to-handle aerobatic models can be flown very smoothly and aerobatics are made extremely easy
    Flight manoeuvres can be flown much more cleanly
    4 different gyro modes: OFF, normal stabilisation, 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 optimisation 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 optimisation is determined automatically from the parameters and works extremely well.
    Extreme flight stability with full 3D capability even with the basic settings.
    The effect for the tail and swashplate can be easily set via the telemetry menu or via selectable encoders.
    Further optimisation options in expert mode for personal flying style and personal requirements.
    Extremely simple adjustment of the basic settings via the telemetry:
    Rotor rotation direction
    Swashplate type
    Swashplate frequency 50...200 Hz
    Swashplate direction
    Swash plate servo centres Servo 1...3 (4)
