DeepSpace Roc 4 O4 Pro 4" 4S FPV Drone ELRS GPS

Looking for a whisper-quiet 4-inch long-range FPV drone that will not alert the entire neighbourhood while cruising for 20 minutes? The DeepSpace Roc 4 O4 Pro features the latest DJI O4 Pro digital video transmission system, a clean deadcat frame layout with zero props in view, and an M10 GPS module for reliable Rescue Mode returns. Engineered for pilots who want HD cinematic FPV footage without hauling a heavy rig, this sub-250g setup pairs DeepSpace Aether1404 3000Kv motors with an F722 AIO FC and BLHeli_32 40A ESCs. At Unmanned Tech, we have tested hundreds of long-range quads over the last decade, and this lightweight cruiser nails the sweet spot between acoustic stealth, flight times, and crystal-clear digital HD video.

Highlights

• Zero Props in Frame: Deadcat arm geometry keeps your DJI O4 Pro HD footage perfectly clean and prop-free.
• Rugged Frame Protection: 7075 aluminum alloy side plates guard the FPV camera, while side covers protect the F722 AIO board from grass and debris.
• Integrated M10 GPS: Enables Betaflight GPS Rescue, distance tracking, and home point bearing for confident long-range exploration.
• Long Flight Times: Cruise for up to 7 minutes on a 4S 750mAh LiPo or up to 20 minutes using a 4S 3000mAh Li-ion pack.

FAQ

Does the prop show in the DJI O4 Pro FPV footage?

No, the Deadcat arm layout shifts the front props back so they stay completely out of the camera field of view.

Can I update the flight controller firmware online?

No, the flight controller requires flashing a local target file (Betaflight 4.5.3 or manufacturer target) via Betaflight Configurator rather than auto-detecting online.
