GEPRC Crocodile75 V3 HD O3

The GEPRC Crocodile75 V3 HD O3 is a purpose-built long-range 7.5-inch flagship. It’s designed to push the boundaries of distance and flight time, effectively acting as a "flying tripod" for mountain surfers and landscape explorers who need to carry large batteries and record in 4K.

• Optimized 7.5-inch Platform: The slightly larger 7.5-inch prop size offers a significant efficiency boost over standard 7-inch quads, providing more lift and smoother cruising at lower RPMs.

• Enhanced Cooling System: GEPRC added a specialized CNC heatsink for the O3 Air Unit. This prevents the "overheat" warning and recording shut-offs during long-distance flights or while sitting on the ground waiting for a GPS lock.

• Dust & Sand Protection: Features protective side panels that shield the flight stack and electronics from debris during takeoffs and landings in wild terrain.

• Integrated Power Design: The XT60 battery plug is integrated into the fuselage structure, making battery connection cleaner and preventing the cable from getting loose or damaged by props.

• Precision Long-Range Hardware: Comes stock with the GEP-M10 GPS for accurate Return-to-Home (RTH) and a SPAN F722-BT-HD V3 flight controller with built-in Bluetooth for field tuning via a smartphone.

Pilot's Reality Check:

• Size & Weight: This is a large, powerful machine. It’s not meant for small parks or suburban flying; the sheer power of the 2806.5 motors makes it dangerous in tight spaces.

• Tuning Requirements: While GEPRC tunes these from the factory, a 7.5-inch quad carries a lot of "prop-mass." You may need to refine your PID tune if you fly with very heavy 6S2P Li-Ion packs to prevent "bobbing" in the wind.

Flyer's POV: Flying the Crocodile75 V3 feels like driving a high-end off-road vehicle. It doesn't feel "twitchy" like a racer; it feels stable, heavy, and incredibly deliberate. When you’re miles out over a mountain ridge, the stability of the 7.5-inch props gives you immense confidence. The O3 footage is rock-solid, and because the frame is so rigid, there’s almost zero jello in the video, even when fighting head-winds on the return trip.
