Product Overview
BETAFPV Pavo20 Pro II O4 Pro 4S ELRS is a compact 2.2-inch digital cinewhoop configured for 4S flight. The supplied DJI O4 Air Unit Pro makes this a video-equipped aircraft, rather than a PNP airframe that requires a separate video system. A compatible radio, goggles, battery and charger are still required.
The 4S version pairs LAVA 1104 5500KV motors with a Cube 3IN1 2–4S 30A flight controller. It differs from the 3S model with 7200KV motors and a 20A controller. Choose batteries for this exact version, not simply by matching the XT30 connector.
A 93.9mm wheelbase, reinforced PA12 ducts and a carbon top plate provide a compact platform for technical freestyle and close-proximity filming. Screw-fixed Gemfan D2.2 three-blade propellers keep the propulsion system securely assembled. Propeller guards reduce exposure, but do not make flight around people or animals risk-free.
The O4 Pro bracket isolates vibration and protects the camera while allowing 0–40° tilt adjustment. It also provides access for optional ND or UV filters. The 29mm-wide battery slot accommodates the recommended 4S batteries; confirm the complete pack dimensions and secure the battery before takeoff.

Version & Battery Selection
This listing is the 4S O4 Pro ELRS version. Match battery cell count to the aircraft: the 3S and 4S models use different motors and flight controllers.
Why Choose the 4S O4 Pro ELRS Version?
This version brings together a factory-matched 4S propulsion system, ExpressLRS control and the included O4 Pro video system in a small ducted aircraft. It suits pilots seeking a compact HD cinewhoop without sourcing and installing a separate VTX. The voltage version matters: the 5500KV motors and 30A continuous ESC are defining components of this listing.

Before Your First Flight
- Use a compatible ExpressLRS 2.4GHz transmitter and goggles supported by DJI O4 Pro. Check firmware compatibility before binding.
- Use the recommended 4S battery and an appropriate balance charger. Battery, charger, radio and goggles are not included.
- GPS mounting brackets are included, but a GPS module is not. ND/UV filters shown in promotional images are optional accessories.
- The manufacturer lists 8 min 30 sec with 580mAh / up to 10 min 30 sec with 680mAh. These are test figures, not guaranteed durations; battery condition, payload, throttle and weather affect endurance.
- Inspect motor screws, propellers, battery retention and camera angle. Follow the manufacturer's setup guide and local operating rules.

Discover BetaFPV
BETAFPV is associated with compact FPV flying, especially tiny-whoop aircraft, small brushless drones, frames, motors, radio controllers and accessories for lightweight builds. Its product range is useful for pilots who want to develop precise control in smaller environments as well as builders experimenting with low-mass setups.
Small FPV aircraft are highly sensitive to component weight, battery choice and physical dimensions. Frame compatibility, motor connector type, propeller diameter, video configuration and receiver protocol can all determine whether a part suits a given BETAFPV generation.
When browsing BETAFPV products, identify the aircraft family and exact model before selecting spares or an upgrade. A part designed for a 65 mm whoop does not necessarily fit a 75 mm or HD-equipped version, even if the products look similar.
