Introduction:

CRUX35/CRUX35 HD is an ultra-lightweight 3.5Inch FPV Freestyle FPV Racing Drone, the weight of the whole drone is only 87g for the analog version and 108g for the digital HD 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 HD version is equipped with CADDXFPV Nebula and Vista HD image transmission system. The analog version is equipped with CADDXFPV Ant ant camera.The receiver version can be SPI 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 and Crux35 HD.
