Product Description

The CaddxFPV Protos FPV Drone RTF Kit is a complete, palm-sized 78mm digital FPV micro drone package engineered for both beginners and experienced pilots. Weighing approximately 104.4 grams, this ultra-light micro quad fits in the palm of your hand and requires no FAA registration or Remote ID in the United States. Constructed from an ultra-lightweight, single-piece polymer unibody frame with integrated propeller guards, the Protos drone offers exceptional crash resistance for indoor cruising and outdoor freestyle flying.

Powered by a Caddx Protos AIO 1.0 flight controller featuring an STM32F405 processor, SPL06 barometer, and integrated ELRS 2.4GHz receiver, the aircraft features three distinct flight modes—Position Hold, Self-Stabilizing, and Manual (Acro)—to help new pilots build confidence while giving advanced pilots full acrobatic freedom. The kit comes completely ready-to-fly with the lightweight Ascent Lite HD digital video transmission system, Ascent 1080p FPV goggles, an A-Link ELRS radio transmitter with Hall-sensor gimbals, three 2S 840mAh batteries, and a 3-bay Type-C charging hub.
