Flywoo FlyLens 75 HD O4 Pro V1.3
Flywoo
The FlyLens 75 with O4 Pro's 4K onboard recording
A 75mm-class 2S whoop built around the DJI O4 Air Unit, marketed by Flywoo as the smallest O4-compatible whoop at 68g dry. It suits pilots who want onboard 4K recording in a whoop sized for indoor and tight-space flying.
Ships with the standard DJI O4 Air Unit, not the O4 Pro — Flywoo's '4K 120fps' marketing describes the O4 Pro unit, and Flywoo sells a separate, distinct FlyLens 75 O4 Pro model. Confirm which air unit a listing includes.
The frame kit is shared across O3 Lite/O4/O4 Pro versions, and several vendor pages still carry O3-era photos, copy-pasted descriptions, and a conflicting 55.4g spec-table weight, so listed specs may not match the shipped configuration.
The TBS CRSF receiver variant carries a price premium over the ELRS 2.4GHz variant.
The ELRS version is priced well above 1S O4 whoops such as the Meteor65/75 Pro O4 class — the premium pays for the 2S platform and shock-mounted camera design.
The full story
The core is Flywoo's GOKU F405 HD 1-2S 12A V2 — F405 BGA MCU, ICM42688P gyro, 12A BLHeli_S/Bluejay , 8MB blackbox, barometer, and a 9V 2A that cleanly powers the DJI air unit — driving ROBO 1003 14,800KV motors on 40mm tri-blade props. The onboard 2.4GHz receiver is serial/UART (CRSF protocol), not , so it takes standard Configurator updates and full telemetry.
A three-point CNC shock-absorbed camera mount is designed to suppress the O4 unit's high-frequency vibration sensitivity for jello-free recording. The modular carbon fiber plus PC frame assembles with five screws, and a quick-release battery bay ships with TPU mounts for 2S 550mAh, 750mAh, and 1000mAh packs, letting you trade weight against Flywoo's claimed 4 to 6.5 minute flight times.
Expect a 2S-only machine for indoor and tight spaces rather than an outdoor cruiser: an independent review of the same frame platform (the O3 version) found it quiet, stable, and crash-resistant indoors with flexible Y-structure prop ducts, but also underpowered and short on flight time outdoors, especially in wind.
The frame kit is shared across O3 Lite, O4, and O4 Pro versions, so spares are easy to source, and the quad is sold in DJI (receiverless), ELRS 2.4GHz, and TBS CRSF variants, plus an 'O4 Wide' edition with a swapped wider-FOV lens. The camera here is the standard O4 Air Unit: 4K tops out at 60fps, with a 117.6-degree , 100Mbps maximum bitrate, and 23GB of fixed internal storage with no microSD slot.
Pros & cons
Pros
- Genuinely light for an O4 HD whoop: Flywoo states 68g with the O4 Air Unit installed (no battery), keeping takeoff weight under 100g even with a 2S pack
- Onboard ELRS 2.4GHz receiver is serial/UART (CRSF protocol) on the GOKU F405 HD 1-2S 12A AIO V2 — not SPI — so it takes standard ExpressLRS configurator updates and full telemetry
- Three-point CNC shock-absorption camera mount is designed to suppress the O4 unit's high-frequency vibration sensitivity for jello-free recording

- Quick-release battery compartment ships with TPU mounts for 2S 550mAh, 750mAh, and 1000mAh packs, letting you trade weight against Flywoo's claimed 4 to 6.5 minute flight times
- Well-specced AIO board: F405 BGA MCU, ICM42688P gyro, 12A BLHeli_S/Bluejay ESC, 8MB blackbox, barometer, and a 9V 2A BEC that cleanly powers the DJI air unit
- Independent review of the same frame platform (O3 version) found it quiet, stable, and crash-resistant indoors with flexible Y-structure prop ducts
- Modular carbon fiber + PC frame assembles with five screws, and the frame kit is shared across O3 Lite/O4/O4 Pro versions so spares are easy to source
- Broad choice of configurations: DJI PNP (receiverless), ELRS 2.4GHz, and TBS CRSF variants, plus a cheaper wide-lens edition
Cons
- Uses the standard DJI O4 Air Unit, which records at most 4K/60fps — Flywoo's '4K 120fps' marketing describes the O4 Pro unit, which this model does not have (a separate FlyLens 75 O4 Pro exists)
- Standard O4 camera limits: 117.6-degree FOV (vs 155 on O4 Pro), 100Mbps max bitrate, and 23GB fixed internal storage with no microSD slot
- 2S-only power system; review of the O3-frame version found it underpowered and short on flight time outdoors, especially in wind — this is an indoor/tight-space machine
Show all 4 cons
- Vendor listings are messy: Flywoo's spec table still lists a conflicting 55.4g weight and O3-era photos, and Pyrodrone/RDQ pages carry copy-pasted descriptions from other models, making spec verification harder for buyers
