Product overview
The Happymodel CrazybeeX DXS F4 1-2s AIO 5in1 is an integrated flight controller for brushless whoops, intended to reduce onboard electronics weight when using a Spektrum transmitter. Its 28.5 × 28.5MM board combines flight control, four motor ESCs, Betaflight OSD, a 5.8G video transmitter and a receiver. The STM32F411CEU6 processor runs at 100MHZ with 512K FLASH and uses an SPI-connected MPU-6000 sensor. Battery input is 1S–2S at DC 2.9V–8.7V, with a built-in 5V 1A BEC.
The onboard BLHeli_S ESCs carry a 5A continuous rating, with 6A peak limited to three seconds, and default to DSHOT600. The DXS receiver supports DSM2/DSMX, up to 12 channels, failsafe and RSSI display; its 200m–300m range is qualified by both transmitter and receiver being 1 m above ground without ground interference. Receiver identity has a material conflict: a separate specification also identifies SPI Frsky D8/D16. The VTX offers switchable 25mw–200mw output across 40 channels in five bands, including Race band, with SmartAudio support.
