CRUX35 is an ultra-light 3.5 inch FPV Freestyle Racing Drone, the weight of the whole drone is only 87g for the analog version. Crux35 serial drone uses Happymodel EX1404 high-efficiency motor and HQPROP 3.5-inch three-bladed propeller to ensure maximum thrust-to-weight ratio with the most efficient premise, which can bring you smooth Freestyle flying experience. The analog version is equipped with ant CADDXFPV Ant camera, as for the receiver version it is UART ExpressLRS which is now the most popular RC connection system and can work very well with Crux35.
