TXCO Tech: The SuperD ELRS 2.4G diversity receiver has an integrated TCXO (temperature-compensated quartz oscillator), which is shared by two RF chips for an extremely accurate clock source. The true diversity receiver with two RF chips and PALNA generates a lot of heat during operation. With the high-quality TCXO, it can withstand extreme temperatures without fear of heat and cold, and continuously emits accurate frequencies for long-haul flights to PALNASX1280), ensuring a longer and more stable flight for FPV drones and RC aircraft. Based on the latest official ExprssLRS. Included is ExpressLRS V3.0.0 firmware. Two dipole T antennas: The SuperD ELRS 2.4G diversity receiver comes with two dipole T antennas that produce an omnidirectional signal for good signal transmission. It is recommended to place the antenna separately and vertically as much as possible to get a better signal. Compatible products: it is not only used for FPV drones, but also for FPV fixed wing aircraft or other FPV aircraft. It provides excellent performance in long-distance flight. It highly meets the reliability requirements for long-haul flights, aerial photography or FPV freestyle tricks. ?Ultra-light weight? Ultra light weight of only 1.1g without antenna. The receiver board has a reasonable layout and is impeccably clean. Very easy to solder.
