Quick Answer
The BetaFPV Meteor Pro II O4 Wide line fixes the one thing that made the original 1S HD whoops frustrating: battery life. The Meteor65 Pro II O4 jumps from 2:40 to over 4 minutes of flight time, while the Meteor75 Pro II O4 pushes to 6 minutes. Both now carry the DJI O4 Wide camera with a 159-degree field of view and 4K/60fps recording.
Why BetaFPV Made Their Smallest Whoop Bigger
The original Meteor75 Pro O4 was a genuine breakthrough: a 37g 1S whoop with DJI digital video. We sold plenty of them. But every customer hit the same wall. Two minutes and forty seconds of flight time on a 300mAh battery is not enough. You spend more time swapping batteries than flying.
The Pro II line addresses this with a counterintuitive fix for a "tiny whoop": they made it bigger. The Meteor65 Pro II grows from a 66mm to 70mm wheelbase. The Meteor75 Pro II keeps 80mm but redesigns the battery slot to accept LAVA II 1S 580mAh and 680mAh packs. More battery capacity means real flying time, and the 2026-edition Freestyle motors with 0.10mm stator cores deliver the low-end torque to carry that extra weight without feeling sluggish.
Meteor65 Pro II vs Meteor75 Pro II: Which Size?
Both share the same core upgrades: DJI O4 Wide Air Unit, Canopy II with four-ball vibration damping, Matrix 1S 3IN1 HD flight controller with onboard ELRS 2.4G, and BT2.0 battery connector. The difference is propeller size and indoor versus outdoor capability.
| Spec | Meteor65 Pro II O4 | Meteor75 Pro II O4 |
|---|---|---|
| Wheelbase | 70mm | 80mm |
| Weight (no battery) | 36.20g | 41.50g |
| Motors | 0802 Freestyle (2026) | 1102 Freestyle (2026) |
| Props | GF 1409 3-blade | GF 1811 3-blade |
| Flight time | ~4:05 (480mAh) | ~5:00 to 6:00 (580-680mAh) |
| Camera | DJI O4 Wide (159-degree FOV) | DJI O4 Wide (159-degree FOV) |
| VTX | DJI O4 Air Unit | DJI O4 Air Unit |
The 65mm Case: Pure Indoor
The Meteor65 Pro II O4 at 36.20g is the one we grab for tight indoor spaces. At 65mm it threads through doorframes and around furniture that the 75mm version clips. The 0802 Freestyle motors with their 0.10mm stator cores produce genuinely surprising low-throttle authority for the class. Four minutes of 4K indoor footage from a sub-40g quad is something that simply was not possible six months ago.
If you already fly the analog BetaFPV Air65, the Meteor65 Pro II O4 is the digital equivalent at roughly the same size, trading 19g of weight for full DJI O4 Wide video quality.
The 75mm Case: Indoor and Outdoor
The Meteor75 Pro II O4 is the one we recommend for pilots who want one whoop that handles both indoor gaps and calm outdoor sessions. The 1102 Freestyle motors and GF 1811 props give enough punch to hold position in light wind, and the 580mAh to 680mAh battery options push flight times past 5 minutes. At 41.50g it is still light enough to bump off walls without damage.
For comparison, the Air75 II is the analog alternative at roughly the same weight. If you already own DJI goggles, the Meteor75 Pro II O4 gives you digital video for around the same flying experience.
Canopy II and Vibration Damping
Both Pro II models ship with the redesigned Canopy II, which uses four shock-absorbing balls to isolate the O4 Air Unit from motor vibration. The original Meteor Pro O4 used a simpler two-ball mount, and some pilots reported jello in their footage. The Canopy II also allows camera tilt adjustment from 15 to 35 degrees, so you can dial in your preferred cruising angle. Replacement Canopy II units are available separately for when the inevitable wall encounter cracks one.
The DJI O4 Wide Camera
The Pro II line uses the O4 Wide variant, not the standard O4 unit. The Wide version offers a 159-degree field of view compared to the standard O4's narrower lens, which makes a real difference in tight indoor spaces where peripheral awareness matters. Both record 4K at 60fps with the same 20ms ultra-low latency transmission to DJI Goggles N3 or Goggles 3. You need DJI goggles to fly these; Walksnail and analog goggles will not work. See our goggles compatibility guide for the full picture.
UK Rules: No Registration Needed
Both the Meteor65 Pro II (36.20g) and Meteor75 Pro II (41.50g) sit well under the 100g threshold, even with a battery installed. Under current UK CAA regulations, drones under 100g with a camera do not require an Operator ID or Flyer ID. This makes them the simplest digital FPV drones to own in the UK: no registration, no test, just charge and fly indoors or on private property with permission.
What We Would Actually Buy
For pure indoor flying, the Meteor65 Pro II O4 is our pick. It fits through tighter gaps, and four minutes of flight time is genuinely usable. The 70mm frame still accepts the same LAVA II batteries as the 75mm version.
For pilots who want a do-everything whoop, the Meteor75 Pro II O4 is worth the extra weight. Six minutes of flight time and enough motor punch for light outdoor conditions make it the more versatile option.
Either way, pair it with a RadioMaster Pocket Crush for ELRS control and a ViFly WhoopStor V3 charger. See our LiPo charging guide for safe 1S battery management.
FAQ
Q: Do I need DJI goggles to fly the Meteor Pro II O4?
A: Yes. The DJI O4 Air Unit only transmits to DJI goggles (Goggles 3, N3, or Goggles V2). Walksnail, HDZero, and analog goggles are not compatible.
Q: Can I use the Meteor Pro II O4 outdoors?
A: The Meteor75 Pro II handles light outdoor conditions well. The Meteor65 Pro II is best kept indoors or in dead calm weather, as its 0802 motors lack the punch to fight wind.
Q: Are spare frames and motors available?
A: Yes. We stock the Meteor65 Pro II frame, Meteor75 Pro II frame, and 1102 Freestyle motors separately. Browse our ready-to-fly collection for the full whoop range.
Q: How does the Pro II compare to the original Meteor Pro O4?
A: The Pro II upgrades to the wider 159-degree FOV O4 Wide camera, adds the Canopy II vibration damping system, uses redesigned 2026 Freestyle motors with 0.10mm stator cores, and accepts larger batteries for significantly longer flight times. See our original Meteor75 Pro O4 review for the full comparison.
