BETAFPV Pavo20 Pro vs Pro II: Which 2.2″ Whoop to Buy
The BETAFPV Pavo20 Pro and Pavo20 Pro II are both 2.2-inch freestyle cinewhoops, but they answer different needs. The original Pro (93.7mm, 66.3g as O3 PNP) is the multi-system modular pick: it swaps between an O3 Air Unit Bracket and an O4 Air Unit Pro Bracket, flies 3S only, and runs up to 6’40” per pack. The Pro II (93.9mm, 72.6g PNP) adds a 4S configuration with the Cube 2-4S 30A FC for up to 10’30” flight time, native O4/O4 Wide/O4 Pro compatibility, an onboard buzzer, GPS brackets and screw-fixed props. The O4 Pro PNP Pro starts at $104.99; the Pro II 4S PNP is also $104.99 with the 4S O4 Pro BNF at $364.99. This guide compares both so you can pick the right 2.2-inch whoop.
What Changed Between Pavo20 Pro and Pro II?
BETAFPV kept the winning formula — LAVA 1104 motors, Gemfan 2.2-inch props, the aerodynamic frame with its 8–11% thrust boost and the classic rubber damper design — and upgraded everything around it. The Pro II gains a second power configuration (4S), a redesigned supported frame that assembles with just four screws, three-system O4 compatibility, fixed props that cannot come loose, a buzzer for crash recovery and GPS readiness. The original Pro remains the only one with true multi-system VTX flexibility, since its O3 Air Unit Bracket also accepts Caddx Vista and RunCam Link.

Prices align at the entry point but diverge at the top: the Pro’s O3 PNP TBS version is $134.99 and its O4 Pro ELRS BNF is $364.99, while the Pro II 4S O4 Pro BNF matches that $364.99 figure. The Pro’s limited NightFire edition (translucent black frame, RGB LED strips, Betaflight LED compatibility) ships as a separate SKU. Note that the Pro II 4S versions were listed as backordered at the time of writing, shipping gradually as inventory arrives.
Power Systems: 3S-Only vs 3S and 4S
The original Pro is a pure 3S machine: LAVA 1104 7200KV motors, the F4 2-3S 20A AIO FC V1 with 25A peak ESC and a 9V 2A BEC for the HD VTX, delivering a thrust-to-weight ratio greater than 5:1 and 6’40” of flight time on the LAVA 3S 550mAh 75C battery. It is agile, responsive and lighter as a result of the simpler electronics.
The Pro II splits the difference by configuration. The 3S version keeps the F4 2-3S 20A FC with the same 7200KV motors, while the 4S version steps up to the Cube 3IN1 2-4S 30A FC — an STM32G473 at 168MHz with a 30A continuous ESC on 2oz copper and integrated Serial ELRS 2.4GHz — paired with 5500KV motors optimized for efficiency. The payoff is endurance: 7’30” on 3S 580mAh, 9′ on 3S 680mAh, and up to 10’30” on the LAVA II 4S 680mAh. From August 2026, the F4 FC in BETAFPV whoops ships randomly with STM32F405 or AT32F435 MCU; both perform identically.
Frames and Brackets: Modular O3 vs O4-Ready II
The Pro’s frame is built around modularity. Its injection-molded HD VTX bracket system lets you swap the O3 Air Unit Bracket — with six camera fixing holes including dedicated wide-angle positions and a tool-free vertical ND filter mount — for the O4 Air Unit Pro Bracket without frame modifications. That makes the Pro the choice for pilots flying O3, Vista or RunCam Link today. The Pavo20 Pro frame assembles with 8 half-thread screws and embedded copper nuts.
The Pro II’s redesigned carbon plate instead commits to DJI’s current lineup: O4, O4 Wide and O4 Pro all mount natively on the O4 Air Unit Pro Bracket. The Pro II frame uses a supported structure with three guided mounting points and a four-screw embedded-nut lock for a more rigid, faster assembly, and the battery slot widens from 20mm to 29mm to fit larger 4S packs. Both frames keep PA12 thickened whoop ducts and rubber dampers for jello-free footage; pre-tuned PIDs on the Pro II are selected via the OSD.
Which props and filters do they use?
The Pro runs Gemfan 2218 3-blade props on a 1.5mm shaft; the Pro II upgrades to GF D2.2 3-blade props secured by screws, eliminating loose props and motors between flights. Filter support is nearly identical: UV/CPL/ND8/ND16/ND32 for O3 cameras and UV/ND8/ND16/ND32 for O4 Pro, swapping tool-free in the vertical bracket mount.
Safety Upgrades: Buzzer, GPS and Fixed Props
The Pro II adds a recovery kit the Pro lacks entirely: an onboard buzzer for locating crashes in tall grass, plus two included GPS brackets compatible with most 12x and 18x modules for return-to-home navigation. Combined with screw-fixed props and the wider battery slot, the Pro II is clearly engineered for pilots who push range and terrain. The Pro counters with its COB LED strip accessory (560mm, 5V) for night visibility and the NightFire limited edition’s built-in RGB lighting with 10 preset effects across 7 colors on the Pro II.
Which Pavo20 Should You Buy?
Buy the Pavo20 Pro if you fly DJI O3 or analog hardware (Vista, RunCam Link), want the lightest 2.2-inch platform, or hunt the NightFire collector’s edition — its modular brackets are unmatched for multi-system builds. Buy the Pro II if you are committed to the DJI O4 ecosystem and want maximum air time: the 4S configuration’s 10’30” endurance, buzzer and GPS readiness make it the better outdoor freestyle and cinematic tool. If you are stepping down in size instead, the Pavo Femto covers the smallest 4K O4 pocket class, and our Pavo20 Pro II guide details the 3S vs 4S setup decision in depth.
Frequently Asked Questions
What is the main difference between Pavo20 Pro and Pro II?
The power system and VTX strategy. The Pro is 3S-only with modular brackets for DJI O3, Vista, RunCam Link and O4 Pro; the Pro II adds a 4S configuration with the Cube 2-4S 30A FC, natively supports O4/O4 Wide/O4 Pro, and includes a buzzer and GPS brackets the Pro lacks.
How much flight time does each version get?
The Pro delivers up to 6’40” on a LAVA 3S 550mAh battery. The Pro II reaches 7’30″–9′ on 3S 580/680mAh packs and 8’30″–10’30” on 4S 580/680mAh, with the 4S 680mAh combination the endurance record for this airframe.
How much do the Pavo20 Pro and Pro II weigh?
The Pro weighs 66.3g as O3 PNP and 71g as O4 Pro PNP. The Pro II weighs 72.6g as PNP and 116.2g with the DJI O4 Pro Air Unit installed. All figures exclude battery, as is standard for PNP cinewhoops.
Is the Pavo20 Pro II compatible with DJI O3?
No — the Pro II supports DJI O4, O4 Wide and O4 Pro only. If you fly the O3 Air Unit, Caddx Vista or RunCam Link, the original Pavo20 Pro with its swappable O3 Air Unit Bracket is the correct platform.
Which battery should I use in each version?
The Pro takes LAVA 3S 450mAh or 550mAh 75C batteries through its XT30 connector. The Pro II accepts LAVA II 3S 580/680mAh, LAVA II 4S 580/680mAh and LAVA 3S 450/550mAh packs — its 29mm unlimited-height battery slot fits the larger 4S cells the Pro’s 20mm slot cannot.
Are the Pavo20 Pro II 4S versions available?
BETAFPV noted the Pro II 4S versions were out of stock with orders shipping gradually as inventory arrives — use the “Notify me when available” option on the product page. The 3S configuration and the original Pro remain in regular supply.
Conclusion: Two Whoops, Two Missions
The Pavo20 Pro and Pro II are not competitors — they are a fork in the roadmap. The Pro keeps multi-system flexibility (O3/Vista/RunCam plus O4 Pro by bracket swap) in the lightest package; the Pro II doubles down on DJI’s O4 era with 4S endurance up to 10’30”, crash-recovery hardware and a faster-assembling frame. Match the platform to your VTX and battery needs, then check current stock and configurations on the Pavo20 Pro and Pavo20 Pro II product pages, and browse the full BETAFPV range in our FPV store.
