Product overview
The RadioLink Electronic Limited R8FM is a miniature radio receiver for integrating remote control into aircraft, including mini racing drones and gliders. Its hardware configuration provides eight channels through SBUS or PPM signal output. At 30*17.5mm (1.18"*0.69") and 2.5g (0.09oz), it suits installations with limited space and weight allowance; its antenna is 85mm long. The product is a receiver component, with flight controller integration forming part of its intended installation.
Integration requires a 3~6V supply, with operating current specified as 38-45mA at 5V. Supported flight controllers include PIXHWAK, MINI PIX, TURBO PIX and APM when they accept SBUS or PPM signals. The radio uses FHSS with 67-channel pseudo-random frequency hopping to help reduce interference. Its stated airborne control distance is 2000 meters (1.24Miles), under unobstructed, interference-free conditions, and may vary with local regulations. The compatible-transmitter specification also requires operation with a flight controller.
