Apex 3″ BNF (O4 / Analog , ELRS 2.4)

Apex 3″ BNF Micro Freestyle FPV Drone – (O4 Wide / Analog)

Big freestyle performance in a pocket-sized footprint. Precision control for tight spots and bando tearing.

Built on the iconic, ultra-rigid Apex 3″ micro geometry, this custom Bind-and-Fly (BNF) drone is engineered specifically for pilots who demand high durability and crisp flight characteristics under 250 grams. Designed to hit narrow gaps and conquer tight spaces, the Apex 3″ features a rigid carbon structure that minimizes frame flex and filter latency for a completely locked-in feel right out of the box.

Equipped with high-torque VCI 1404 4000KV motors, this micro quad offers instant throttle response and smooth low-end authority. Choose between the cutting-edge DJI O4 Air Unit Wide Pro for crisp, high-definition digital video feed, or the lightweight Analog Video System for raw, ultra-low-latency flying. Standard with a high-refresh-rate 2.4GHz ExpressLRS (ELRS) receiver, the Apex 3″ is optimized for 3S and 4S batteries (650mAh to 850mAh) for the ideal balance between flight time and explosive freestyle power.
