The Graupner GR-18 +3xG +3A +Vario HoTT receiver has a range of approx. 4000m and can be assigned up to 9 channels.With GRAUPNER HoTT 2.4 GHz technology, the 9-channel receiver has a new hopping telemetry transmission high-frequency section with state-of-the-art components and the latest software. A hardware antenna diversity for optimum reception. The receiver voltage and temperature, signal strength and altitude parameters are transmitted without additional sensors.Software for fixed-wing models, flybarless helicopters and racecopters is available. 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 Compact size and minimum possible weight Very high receiver input sensitivity, therefore very long range Front-mounted servo connections facilitate installation and always guarantee firm connections Failsafe, hold, OFF and standard (channel 1 = failsafe, all others hold) programmable Height sensor for vario function Compatible with all HoTT remote controls 3-axis gyro + 3-axis acceleration sensors + vario Stabilization of the flight model in difficult wind conditions for up to 3 axes Natural flight behavior due to proportional gyro suppression Very good stabilization for cleanly flown flight figures The 3-axis gyro means that even difficult-to-handle aerobatic models can be flown very smoothly and aerobatics are made extremely easy Flight figures can be flown much more cleanly Simple adjustment of the gyro assignment Adjustment of parameters via HoTT telemetry Extremely sensitive altitude sensor for vario function (10 cm/s) and altitude measurement Flybarless system for helicopters Extremely quick and easy, convenient and fast adjustment via Hott transmitter telemetry menu Basic setting completed in just a few minutes Fast and innovative axis assignment for flexible installation direction Space-saving, therefore easy storage and fewer cables Extremely light (GR-24 Pro 18g / GR-1814g) Special vibration-resistant 3 axis sensors of the latest generation Pirouette optimization of the swashplate and direction of the tail torque compensation are automatically detected 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 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 Proven stabilization software for fixed-wing models already integrated incl. own vario sensor Telemetry support for own Hott sensors and Hott sensors from other providers SUMD output for other flybarless receivers. HV suitable. Input voltage range 3.6...8.4 V Can be programmed and operated with all previously available HoTT transmitters with telemetry Flybarless for helicopters Simple programming of the basic settings via telemetry Pirouette optimization is automatically determined from the parameters and works extremely well Extreme flight stability with full 3D capability even with the basic settings Effects for 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
