The receiver provides constant, real-time information on receiver voltage, temperature and signal strength, which is sent back to the transmitter without the need for extra sensors.\u003c\/p\u003e\n\n\u003cp\u003eThe system has a dual, full-range 2.4 GHz diversity antenna system that continuously switches to the best antenna signal and uses the most recently used antenna to receive the telemetry downlink. This ensures that the return channel data is always sent via the best-placed antenna, so telemetry information is available throughout the flight.\u003c\/p\u003e\n\n\u003cp\u003eHoTT (Hopping Telemetry Transmission) is based on frequency hopping spread spectrum technology (FHSS) with up to 75 channel changes, which gives high operational reliability and immunity to external interference. The system offers integrated real-time telemetry and is fully programmable via the Smartbox. The GR-24 also supports digital output (SUMD, SUMDV3, SUMDIN, SUMO, SUMI, SBUS) for flight controllers such as V-Stabi, Microbeast, Brain, Bavarian Demon, 3Digi, Naze and others.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 75 channel changes for high operational reliability and immunity to external interference\u003c\/li\u003e\n\u003cli\u003eWide voltage range of 3.6 V - 8.4 V (functional down to 2.5 V) for safe operation during voltage fluctuations\u003c\/li\u003e\n\u003cli\u003eDual power connection\u003c\/li\u003e\n\u003cli\u003eWireless setup and access technology\u003c\/li\u003e\n\u003cli\u003eLED display of operating status\u003c\/li\u003e\n\u003cli\u003eIncreased receiver sensitivity with vertical range of up to 4,000 metres\u003c\/li\u003e\n\u003cli\u003eEasy, front-facing servo connection\u003c\/li\u003e\n\u003cli\u003eFail-safe, hold, OFF and standard programmable directly from the transmitter or receiver (channel 1: fail-safe; all others: hold)\u003c\/li\u003e\n\u003cli\u003eProgrammable warning thresholds for low voltage and for low or high temperature\u003c\/li\u003e\n\u003cli\u003eWireless real-time flight data logging\u003c\/li\u003e\n\u003cli\u003eUltra-fast rebinding with a HoTT radio\u003c\/li\u003e\n\u003cli\u003eDigital output (SUMD, SUMDV3, SUMDIN, SUMO, SUMI, SBUS) on input or output connector\u003c\/li\u003e\n\u003cli\u003eSelectable frame rates between 10ms and 20ms\u003c\/li\u003e\n\u003cli\u003eCompact and light\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSystem properties (HoTT)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSimple and extremely fast binding\u003c\/li\u003e\n\u003cli\u003eRange test and low-voltage warning\u003c\/li\u003e\n\u003cli\u003eExtremely wide operating voltage range from 3.6 V to 8.4 V (functional down to 2.5 V)\u003c\/li\u003e\n\u003cli\u003eFailsafe with free channel mapping\u003c\/li\u003e\n\u003cli\u003eBinding of any number of receivers for channel expansion (max. 32 channels)\u003c\/li\u003e\n\u003cli\u003eUp to 4 servos can be controlled simultaneously in blocks with a servo cycle time of 10 ms (digital servos only)\u003c\/li\u003e\n\u003cli\u003eMaximum noise immunity thanks to optimised frequency hopping and wide channel spread\u003c\/li\u003e\n\u003cli\u003eExtremely fast rebinding, even at maximum distance\u003c\/li\u003e\n\u003cli\u003eReal-time telemetry evaluation\u003c\/li\u003e\n\u003cli\u003eFuture-proof with update option via USB interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature range: -15 to +70 °C\u003c\/li\u003e\n\u003cli\u003eAntenna length: 2 x 145 mm (antenna 30)\u003c\/li\u003e\n\u003cli\u003eTotal weight, approx.: 16 g\u003c\/li\u003e\n\u003cli\u003eFrequency: 2400 - 2483.5 MHz\u003c\/li\u003e\n\u003cli\u003eRange, approx.: 4,000 m\u003c\/li\u003e\n\u003cli\u003eDimensions: 46 x 31 x 14 mm\u003c\/li\u003e\n\u003cli\u003eModulation: 2.4 GHz FHSS\u003c\/li\u003e\n\u003cli\u003eCurrent draw: 70 mA\u003c\/li\u003e\n\u003cli\u003eSupply voltage: (2.5) 3.6 - 8.4 V\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Graupner","offers":[{"title":"Default Title","offer_id":43581286088782,"sku":"GRA33512","price":1099.0,"currency_code":"DKK","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/9672\/2510\/files\/GRA33512_6bdb78b6-9879-4a4d-9b05-ef66f9809171.jpg?v=1774566098","url":"https:\/\/hobbyviking.com\/products\/gr-24-hott-2-4-ghz-receiver-gra33512","provider":"Fjernstyret.dk","version":"1.0","type":"link"}
