BetaFPV Meteor65 Pro O4
BetaFPV
The smallest DJI O4 — 65mm 1S, the only O4 this tiny
Current best price is 46% above the manufacturer's list price ($184.99).
Buy at Pyrodrone ↗The Meteor65 Pro O4 is BetaFPV's 66mm-wheelbase 1S brushless whoop and the smallest to carry a genuine DJI O4 Air Unit, tuned soft for smooth cinematic and indoor HD filming rather than racing.
Units shipped after December 25, 2025 use a BMI270 gyro in place of the original ICM42688. Confirm which gyro your unit has before flashing flight-controller firmware.
BetaFPV has discontinued the model and both direct variants are sold out; remaining supply is limited to US retailer stock.
With the model discontinued, remaining retailer stock typically sells at a significant premium over its original MSRP.
The full story
Released January 2025, it pairs the Meteor65 Pro frame with 0802SE 19500KV motors and Gemfan 35mm 3-blade props on the Matrix 1S 3IN1 HD , purpose-built for 1S O4 whoops: an STM32G473 MCU, a 12A continuous/18A peak BLHeli running Bluejay, onboard serial 2.4GHz, and a 5V/3A sized to hold the O4 video link stable through voltage sag.
BetaFPV positions it explicitly as a cinematic and indoor HD filming whoop, not a racer. The factory tune runs soft PIDs, adapted rates, and an extended throttle range for smooth, stable flying out of the box, and the O4 camera rides on a four-ball shock-absorbing mount that isolates high-frequency vibration to keep HD footage jello-free. A redesigned canopy sets camera angle anywhere from 10 to 35 degrees.
The tradeoff is weight: at 28.53g without battery (roughly 36.8g all-up with the recommended 8.3g LAVA 1S 300mAh pack) it is heavy for a 65mm 1S whoop, and the O4 air unit is a lot for this small a platform — reviewer and community consensus is that the 75mm Meteor75 Pro O4 sibling carries it noticeably better. BetaFPV claims a 2:40 flight time, and the soft tune's limited thrust headroom makes it a poor pick for or racing.
The fitted air unit is the standard, non-Pro DJI O4: a 1/2-inch sensor, 117.6-degree , up to 4K/60 recording to 23GB fixed internal storage (no microSD, no D-Log M color mode), and FCC transmit power up to 1W EIRP. The onboard ELRS receiver is serial (), so it takes standard updates without version-lock, though the BT2.0 battery connector keeps you on BetaFPV-ecosystem 1S packs and chargers.
Pros & cons
Pros
- Genuine DJI O4 digital HD video with onboard 4K/60 recording on an indoor-size 66mm whoop
- Onboard serial (UART) ELRS 2.4GHz receiver, not SPI, so standard ExpressLRS firmware updates apply without SPI version-lock issues
- Matrix 1S 3IN1 HD FC was purpose-built for 1S O4 whoops; its 5V/3A BEC keeps the O4 video link stable through voltage sag, bench-verified solid even below 2.8V battery voltage
Show all 8 pros
- Four-ball shock-absorbing O4 camera mount isolates high-frequency vibration and prevents jello in HD footage
- Canopy supports adjustable camera angle from 10 to 35 degrees without props or frame in frame
- Factory tune (optimized PIDs, extended throttle range, adapted rates) delivers smooth, stable cinematic flying out of the box
- 12A continuous / 18A peak ESC provides power headroom for the O4 payload
- variant without HD was offered for pilots who already own an O4 unit
Cons
- The O4 air unit's weight is a lot for the 65mm platform; reviewer and community consensus is that the 75mm sibling (Meteor75 Pro O4) carries the O4 noticeably better
- Flight time is only 2:40 per pack by BetaFPV's own spec, less than half the Meteor75 Pro O4's claimed 5:30
- Heavy for a 65mm 1S whoop at 28.53g before battery (~36.8g with the recommended 8.3g LAVA 300mAh pack)
Show all 8 cons
- Carries the standard O4 unit, not the O4 Pro: narrower 117.6-degree FOV, smaller 1/2-inch sensor, no D-Log M color mode, and 23GB fixed internal storage with no microSD slot
- Soft cinematic tune and limited thrust headroom make it a poor choice for acro or racing
- Discontinued at BetaFPV with both direct variants out of stock; remaining US retailer stock sells well above the original $184.99 MSRP
- Units shipped after Dec 25, 2025 switched from the ICM42688 gyro to BMI270, so the gyro version must be verified before flashing FC firmware
- BT2.0 battery connector ties you to BetaFPV-ecosystem 1S packs and chargers
