GR-24 PRO +3xG +3A + 3M + Vario HoTT- 2.4 GHz receiver

The Graupner GR-24 +3xG +3A +Vario HoTT receiver has a range of approx. 4000m and can be assigned up to 12 channels. In addition, a 3-axis gyro system, a 3-axis accelerometer and vario are integrated.
With GRAUPNER HoTT 2.4GHz technology, the receiver has a secure hopping telemetry transmission high-frequency section with high-quality components and state-of-the-art software. A diversity antenna always switches to the better antenna signal for reception and always uses the antenna that was last used for reception for transmission. This ensures that the return channel data is transmitted via the better positioned antenna.
The receiver transmits the parameters "Receiver voltage", "Receiver temperature" and "Signal strength" to the transmitter without additional sensors.

Features

•     The use of up to 75 channels ensures extreme operational reliability and is insensitive to external interference
•     The wide receiver voltage range of 3.6 V - 8.4 V (functional up to 2.5 V) ensures full functionality even with voltage fluctuations
•     Two LEDs signal the operating status
•     Compact size and extremely lightweight
•     Very high receiver input sensitivity, therefore very long range
•     Servo connections on the front make installation easier and always guarantee firm connections
•     Failsafe, hold, OFF and standard (channel 1 = failsafe, all others hold) programmable

Features 3-axis gyro + 3-axis accelerometer + vario

•     Basic setup completed in just a few minutes
•     Stabilization of the flight model in difficult wind conditions for up to 3 axes
•     Various flight modes: off, normal, heading lock mode with I fade-out at rudder deflection, turn rate mode
•     The flight modes can be switched via a channel if required. The modes for aileron/elevator and rudder can be set separately
•     Natural flight behavior due to proportional gyro fade-out
•     Very good stabilization for cleanly flown flight figures
•     The 3-axis gyro allows even difficult-to-control aerobatic models to be flown very smoothly
•     Flight figures can be flown much more cleanly
•     Simple adjustment of the gyro assignment
•     Simple adjustment of parameters via HoTT telemetry
•     Extremely sensitive altitude sensor for vario function (10 cm/s) and altitude measurement
•     Fast and innovative axis assignment for flexible installation direction
•     Special vibration-resistant 3-axis sensors of the latest generation
•     Pirouette optimization of the swashplate and direction of the tail torque compensation are detected automatically
•     All common helicopter swashplates 90/120/135/140 degrees
•     Adjustable swashplate rotation up to 90 degrees for multi-blade heads
•     Clear standard menu and selectable expert menu if required
•     Sensitivity parameters can be adjusted during flight for speed and style

Flybarless for helicopters

•     SUMD output for other flybarless receivers
•     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.
•     The effect for the tail and swashplate can be easily set via the telemetry menu or via selectable encoders.
•     Further optimization options in expert mode for personal flying style and personal requirements.
•     Extremely simple adjustment of the basic settings via telemetry:

(direction of rotor rotation, swashplate type, swashplate frequency 50...200 Hz, swashplate direction, swashplate servo centers servo 1...3, swashplate cycl. Set swashplate cyclic travel to 7°, swashplate pitch travel A/B, swashplate limit, swashplate rotation, tail servo center pulse 760µs, 960µs, 1.5 ms, tail servo frequency 50...333 Hz, tail servo center position, expo yes/no, logging for service purposes, simple gyro axis assignment,...).

    Further parameters can be set in expert mode.
