CRUX35 HD is an ultra-lightweight 3.5Inch FPV Freestyle FPV Racing Drone, the

weight of the whole drone is only 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 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 HD.
