Product Description

The Pavo Femto is the "shrunken" sibling of the Pico, designed for the ultra-micro 1S digital or analog experience.

Ultra-Light 1S Digital Platform: Specifically optimized for the Walksnail Avatar 1S or HDZero Whoop Lite systems. The Femto proves that you don't need a heavy 2S battery to get high-definition video; it maintains extreme agility while keeping the takeoff weight incredibly low.
Precision Weight Distribution: The "pusher" configuration and centralized battery mount ensure a low center of gravity. This makes the Femto feel "locked-in" during tight cornering and prevents the pendulum effect common in top-heavy micro drones.
Durable 75mm Frame Architecture: Built on a reinforced frame that balances flexibility and stiffness. It’s designed to bounce off walls and obstacles, making it the perfect tool for high-speed indoor racing or cinematic house tours where space is at a premium.
Plug-and-Play Maintenance: The Femto uses a modular design for the VTX and camera mounts, allowing for quick swaps or repairs. This is a massive advantage for pilots who push their micros to the limit in indoor "bando" sessions.

Technical Specifications:

Wheelbase: 75mm
Weight: ~28g (without battery)
Flight Controller: F4 1S 5A AIO (Serial ELRS 2.4G)
Motors: 1102 22000KV Brushless
Propellers: Gemfan 1610 2-Blade (40mm)
Battery Connector: BT2.0
VTX Support: Walksnail Avatar 1S / HDZero / Analog
Camera Angle: 25° - 50° Adjustable
Recommended Battery: 1S 450mAh - 550mAh BT2.0

The Pilot's Reality Check:
- Throttle Management: With 22000KV motors, this little beast has a lot of "pop." Beginners should add a slight throttle limit in Betaflight to avoid hitting the ceiling during the first few flights.
- 1S Voltage Sag: Digital systems are sensitive to voltage. To get the best flight times and prevent video brownouts, use high-quality BT2.0 batteries. Old-fashioned PH2.0 connectors simply won't provide the current this drone needs.

🤔 Frequently Asked Questions

How does this compare to the Pavo Pico? It looks almost the same.
The Femto is actually smaller (75mm wheelbase vs the Pico's 80mm) but more powerful. While the Pico is often flown on 1S or 2S, the Femto is optimized for 2S, giving it a much better thrust-to-weight ratio. This makes it more capable of handling outdoor winds and more "snappy" during freestyle moves, whereas the Pico is more of a pure indoor cruiser.
Is it noisy? I want to fly it in my backyard without annoying neighbors.
Because it uses smaller 40mm props compared to the 45mm props on larger whoops, the motors have to spin faster to keep it in the air. This results in a higher-pitched "whine" than larger drones. It’s not "loud" like a 5-inch racing drone, but it’s definitely more noticeable than a silent 1S tiny whoop.
Can I use my old 1S batteries with this?
No, the Pavo Femto is built for 2S (7.4V) batteries and uses an XT30 connector. If you try to plug in a standard 1S battery with a PH2.0 or BT2.0 connector, it won’t fit, and even with an adapter, the drone wouldn't have enough voltage to take off. You’ll want 2S LiHV packs around 450mAh to 550mAh.
How well does the 4K video hold up on such a small frame?
It’s surprisingly good. BetaFPV included a dedicated "soft mount" system with silicone damping balls for the O4 camera. This is crucial because tiny drones often have high-frequency vibrations that can make digital video look shaky. The damping system does a solid job of keeping the footage "clean" enough for professional-looking social media clips.
Is the O4 Air Unit included, or do I have to buy it separately?
This depends on the version you buy. There is a "BNF" (Bind-and-Fly) version that comes with the O4 unit pre-installed, and a "PNP" (Plug-and-Play) version that is just the frame and electronics, requiring you to provide and install your own O4 Air Unit. Always double-check the listing so you don't end up with a "brainless" drone!
