BetaFPV Pavo Femto Brushless Whoop Quadcopter

The BetaFPV Pavo Femto O4 is a next-generation ultra-micro cinewhoop, purpose-built to carry the DJI O4 Air Unitin the smallest possible frame. With an 80 mm wheelbase, 45 mm propellers, and 1102 22000KV motors, this quad strikes an incredible balance between compact indoor agility and stable outdoor cruising.

Unlike typical micro whoops that wobble under HD weight, the Pavo Femto O4 was designed from the ground up with reinforced structure, optimized power system, and dedicated camera isolation. The result is buttery-smooth HD footage from a frame you can fly through hallways, tight gaps, or cinematic living room scenes — yet still strong enough to punch outdoors for creative transitions.

This quad represents the smallest platform currently supporting DJI O4, making it a dream rig for content creators, vloggers, and FPV filmmakers who need portable HD quality without carrying bulky drones.

🔋 Power System & Flight Efficiency

The Pavo Femto O4 uses 1102 22000KV brushless motors paired with 45 mm tri-blade props, a proven combination for micro quads that need both torque and efficiency. Powered by a LAVA 1S 550 mAh battery, the quad delivers around 4–5 minutes of flight time depending on environment and flying style.

Thanks to the enhanced 12 A ESC built into the flight controller, throttle response is immediate, while current protectionensures reliability. The quad feels lively yet easy to grade, giving pilots precise control for both slow cinematic passesand snappy freestyle bursts.

🧠 Flight Controller & Receiver Integration

At its heart is the Matrix 1S 3-in-1 HD Flight Controller, combining FC, ESC, and ELRS 2.4 GHz receiver into one lightweight stack. This reduces wiring clutter, improves durability in crashes, and keeps latency low. The G473 MCUprovides faster processing, meaning stabilization loops and gyro filtering run cleaner — keeping O4 video free from jitter.

🎥 O4 HD Video — Small Frame, Big Cinematic Potential

The Pavo Femto O4 is optimized for the DJI O4 Air Unit, giving you 1080p/120fps or 4K video capability in an 80 mm whoop. To keep footage stable, BetaFPV added a shock-absorbing camera mount with four soft isolators that filter out high-frequency vibrations. The camera mount also offers an adjustable tilt (10°–35°) so pilots can switch between smooth cinematic angles and faster FPV racing lines.

This makes the Femto O4 a unique tool: flyable anywhere indoors, but capable of producing video polished enough for professional edits.
