Flywoo Flytimes 85 HD O4
Flywoo
Light 2S , side bumpers only — O4 edition
Flywoo's Flytimes 85 HD O4 is an 85mm 2S micro with TPU prop guards built around the standard DJI O4 Air Unit. It suits pilots mixing indoor and outdoor flying who want prop protection and class-leading 2S flight times.
US street pricing across variants and vendors runs well above the price cited at the time of the original review.
The full story
Flywoo builds the frame from a Y-shaped aluminum-alloy bracket with TPU prop guards, carrying the GOKU F405 HD 1-2S 12A V2 flight controller with onboard 2.4G, ROBO 1003 14800KV motors, and 2-inch 2015 bi-blade props. A CNC shock-absorption camera platform steadies the O4 unit, and a quick-release battery bay accepts 2S 550, 750, or 1000mAh packs — all three TPU mounts come in the box. Bare weight is 58.9g.
The design was co-developed with a Chinese photography studio for indoor commercial shooting, and endurance is the headline: Flywoo quotes 5m30s to 9m of flight at 75km/h cruise depending on pack. Oscar Liang characterizes it as a hybrid of the Flylens 85 and Flybee20 with lighter prop guards, best for mixed indoor and outdoor flying.
It runs the standard DJI O4 Air Unit rather than the O4 Pro; Flywoo sells a Flytimes 85 O4 Pro as a separate model, and this page covers the standard-O4 version. Receiver options span onboard ELRS 2.4G, TBS CRSF, and DJI variants, and a Wide edition swaps in Flywoo's native 159-degree wide-angle O4 lens for a more immersive view.
Pros & cons
Pros
- Onboard ELRS receiver is UART/serial (CRSF protocol), not , so it runs standard firmware and updates via the ELRS ecosystem
- Class-leading endurance figures: Flywoo quotes 5m30s (550mAh), 7m30s (750mAh), and 9m (1000mAh) on 2S packs
- Quick-release battery compartment with included TPU mounts for 550/750/1000mAh 2S packs lets you trade weight for flight time per session
Show all 8 pros
- CNC shock-absorption camera platform targets jelly-free onboard 4K/60 footage from the O4 unit
- 58.9g without battery - lighter than the Flylens 85 while keeping prop protection the Flybee20 lacks
- GOKU F405 HD AIO V2 is well equipped: ICM42688P gyro, 12A BLHeli_S/Bluejay , 5 UARTs, barometer, 8MB blackbox, switchable 9V
- Multiple receiver options across vendors: ELRS 2.4G, TBS CRSF, and DJI PNP variants
- Wide edition available with Flywoo's native 159-degree wide-angle O4 lens for a more immersive FPV view
Cons
- Uses the standard DJI O4 Air Unit, not the O4 Pro: smaller 1/2-inch sensor, 4K/60fps cap, and no D-Log M color - the O4 Pro version is a separate, pricier SKU
- Reviewer guidance is that unless you specifically need propeller protection, the same-electronics Flybee20 is the better pick for outdoor freestyle
- A 2S 2-inch quad is questionably practical for the tight indoor flying it is marketed for
Show all 4 cons
- Base model ships with the stock narrow O4 lens; the 159-degree wide requires the separate Wide edition or Flywoo's add-on lens
