Weighing only 87g (analog) or 108g (digital), it delivers incredible thrust-to-weight ratio and freestyle capabilities. Powered by the EX1404 motors and HQProp tri-blade props, Crux35 offers a smooth and responsive flying experience. Ideal for freestyle, cinematic flying, or even racing.
Note: Ensure correct VTX power settings for your region. Always verify Betaflight and ExpressLRS configurations before flight.
