Flywoo FlyLens 85 HD O4 Pro V1.3 LED
Flywoo
The big FlyLens with O4 Pro 4K and LED trim
Flywoo's 85mm 2S whoop with guarded 2-inch props and a DJI O4 Air Unit, marketed as the lightest 2-inch O4 drone at 68.8g without battery. It suits pilots who want onboard 4K/60 recording in a whoop-sized package.
The 12A BLHeli_S ESC ships with Bluejay 48kHz firmware; Flywoo warns against flashing 96kHz Bluejay firmware due to motor-idle and stall issues.
Street pricing sits at the premium end for an 85mm whoop across US vendors, and the TBS Crossfire receiver variant carries a further premium over the ELRS and PNP options.
The full story
Released in early 2025, the build centers on Flywoo's GOKU F405 HD 1-2S — a 12A BLHeli_S running Bluejay 48kHz firmware, an ICM42688P gyro, and onboard serial — driving ROBO 1003 14,800KV motors on reverse-mounted Gemfan 2015 bi-blade props. The carbon frame carries PC injection-molded prop guards, a three-point damped camera platform, and a quick-release battery bay with TPU mounts for 2S 550, 750, and 1000mAh packs.
The DJI O4 Air Unit records 4K/60 at 100Mbps onboard, so no separate HD camera is needed; storage is the unit's fixed internal memory — roughly 24GB, about 30 minutes of 4K — with no microSD slot. The three-point damped CNC camera platform produces jello-free footage, confirmed smooth in reviews of the FlyLens 85 platform.
It sells in ELRS 2.4GHz, TBS Crossfire, and receiver-less DJI variants. The onboard ELRS receiver is a genuine serial unit (Flywoo EL24P on UART1), flashable through the Configurator rather than baked-in . The box is a complete kit — eight spare 2015-2 props, an O4 UV lens filter, a 90-degree Type-C data cable, a screwdriver, and hardware — and the XT30 battery lead is reinforced with Flywoo's XT30UP strain-relief sheath.
Pros & cons
Pros
- One of the lightest 2-inch DJI O4 quads sold, at a manufacturer-stated 68.8g without battery
- Onboard 4K/60 (100Mbps) recording from the DJI O4 air unit, so no separate HD camera is needed
- Genuine serial (UART) ELRS 2.4GHz receiver onboard (Flywoo EL24P on UART1) - flashable via ExpressLRS Configurator, not an SPI receiver
Show all 10 pros
- Quick-release battery bay with included TPU mounts for 2S 550/750/1000mAh packs lets you trade weight for flight time
- Long claimed endurance: 9 min on a 2S 1000mAh and 7.5 min on a 750mAh
- Three-point damped/CNC camera platform produces jello-free footage, confirmed smooth in reviews of the FlyLens 85 platform
- Well-specced AIO: F405 BGA MCU, 6 UARTs, DPS310/SPL06 barometer, 8MB blackbox, 9V 2A with software power cut-off switch, Bluejay 48kHz ESC firmware with bidirectional DShot/RPM filtering
- XT30 battery connector with reinforced Flywoo XT30UP strain-relief sheath
- Complete kit: 8 spare 2015-2 props, O4 UV lens filter, 90-degree Type-C data cable, screwdriver, and hardware set included
- Sold in ELRS 2.4GHz, TBS Crossfire, and receiver-less DJI PNP variants at major US vendors
Cons
- Uses the standard DJI O4 unit, not the O4 Pro: smaller 1/2-inch sensor, narrower 117.6-degree , 4K capped at 60fps, single antenna, and lower transmit power than the O4 Pro version of this same quad
- Real-world flight times in reviews of the FlyLens 85 platform run well below the 9-minute claim (about 5 minutes on a 2S 1000mAh with the heavier O4 Pro build)
- Reviewers found the FlyLens 85 notably loud, especially indoors
Show all 8 cons
- Camera angle adjustment range is limited by the mount's screw positions
- Battery holder system described as fidgety in review
- O4 recording is limited to the unit's fixed internal memory (roughly 24GB, about 30 minutes of 4K) with no microSD slot
- Expensive for an 85mm whoop, with the TBS Crossfire variant carrying a further premium
- BLHeli_S 12A ESC ships with Bluejay 48kHz and Flywoo warns against flashing 96kHz firmware due to motor-idle/stall issues
