BetaFPV Meteor75 Pro O4 Pro ELRS Brushless Whoop Quadcopter

The Meteor75 Pro O4 takes the classic 75 mm whoop formula and rebuilds it specifically for DJI O4 digital video. Instead of simply squeezing an HD unit into a tiny frame, this platform is holistically tuned: a larger 80.8 mm wheelbase, 1102 | 22000KV motors, and 45 mm tri-blade props are matched to a strengthened Matrix 1S 3-in-1 HD flight controller and 12 A continuous ESC so the quad can carry O4 cleanly without wobble, jello, or saggy throttle response. The result is a 1S whoop that behaves like a mini cinema rig—smooth camera moves, predictable altitude holds, and enough headroom to turn tight indoor spaces into usable sets while still being confident outdoors.

Where most 1S whoops struggle is vibration and power delivery under the extra mass of HD gear. Meteor75 Pro O4 addresses both: shock-absorbing camera isolation tailored to O4’s gyro-based stabilization and a powertrain that keeps the disc loading and torque in the sweet spot. With the recommended LAVA 1S 550 mAh pack, BetaFPV quotes around 5:30 per flight—impressive for a digital 1S whoop, and a strong indicator that the prop/motor/ESC triad is properly matched.

🔋 Power System & Efficiency — Built Around 45 mm Lift

The combo of 1102 | 22000KV motors and GF 45 mm 3-blade props gives you real mid-throttle authority without spiky current draw. Paired with the enhanced 12 A ESC and LAVA 1S 550 mAh battery, you get clean punch-outs, steady cruising, and a throttle curve that’s easy to grade for cinematic moves. This is exactly why the Pro O4 can carry the DJI O4 Air Unit yet keep the flight feel tight and responsive on 1S.

🧠 Flight Controller & Stability — Matrix 1S 3-in-1 HD

At the core is the Matrix 1S 3-in-1 HD FC (FC + ESC + ELRS 2.4G RX). It’s purpose-built for digital 1S whoops, so voltage regulation and ESC behavior are tuned to avoid image browning and gyro noise when you blip throttle or bounce off walls. The integrated design trims weight and wiring, improving reliability and serviceability after inevitable whoop dings.
