NOTICED: SPI ELRS version Crux35 were discontinued. The new ELRS V2 version comes with CrazyF411 ELRS AIO flight controller built-in UART ExpressLRS receiver.
CRUX35 is an ultra-lightweight 3.5Inch FPV Freestyle FPV Racing Drone, the weight of the whole drone is only 87g for the analog version. The Crux35 serials drone use Happymodel EX1404 high-efficiency motor and HQPROP 3.5-inch three-blade propeller to ensure the largest thrust-to-weight ratio under the most efficient premise, which can bring you a smooth Freestyle flying experience.
The analog version is equipped with CADDXFPV Ant ant camera.
The receiver version can be UART ExpressLRS and SPI Frsky (S-FHSS compatible) for choose.
ExpressLRS is the most popular RC link system by now , it could performance very well with Crux35.
