Which DJI O4 Whoop to Buy: Meteor65 Pro II vs Meteor75 Pro II vs Nimble65
Short version: for most DJI pilots, buy the Meteor75 Pro II O4. It's the one I fly. Pick the Meteor65 Pro II O4 if your rooms are tight. The Nimble65 HD O4 is the lightest, but it carries the standard O4, not the Wide, and Oscar Liang calls it underpowered. All three need DJI goggles, and none is a first whoop.
This page covers 1S ducted O4 whoops only. DJI lists Goggles 3, N3, 2 and Integra. Store links go through /go/ affiliate redirects at no extra cost to you; the BetaFPV one opens the store's home page.
The three, side by side
| Meteor65 Pro II O4 | Meteor75 Pro II O4 | Nimble65 HD O4 | |
|---|---|---|---|
| Size | 70mm | 80mm | 65mm |
| Weight, no pack | 36.20 g | 41.50 g | 27 g (Oscar) |
| Camera | O4 Wide | O4 Wide | Standard O4 |
| Receiver | Serial ELRS | Serial ELRS | SPI ELRS |
| Connector | BT2.0 | BT2.0 | A30 |
| Claimed flight | 4:05 on a LAVA II 480 | 5:00 on a 580, 6:00 on a 680 | not listed |
BetaFPV's figures are from its product pages and are manufacturer claims. Nimble65 details are from Oscar and whoopindex, because Sub250's listing doesn't publish a spec list.
Meteor75 Pro II O4: the default
I've flown it: about three minutes per LAVA II 480 before I landed, with clear headroom left. That's a normal session, not a drain test, and it roughly matches Oscar's 3:00–3:30 on a 480. It's the strong second quad after analog. The O4 Wide is the point: DJI rates it at 159° against the standard O4's 117.6°. Packs, firmware and the analog sibling are in the Meteor75 Pro II O4 Wide guide. BetaFPV store.
Meteor65 Pro II O4: tighter rooms, same Wide camera
BetaFPV widened this one from 66mm to 70mm so it could carry a LAVA II 480. It names the old Meteor65 Pro O4's 2:40 as the reason. It's 5.3 g lighter than the Meteor75 on the listed weights, with the same FC, receiver, BT2.0 plug and 480 pack, so one box of packs covers both Meteors. Whoopindex notes no third-party reviews yet, so treat 4:05 as BetaFPV's number. BetaFPV store.
Nimble65 HD O4: lightest, but read the caveats
Oscar's verdict: "I cannot recommend this model." He found the 0702 27000KV motors underpowered for 27 g, and the original units fed the O4 straight from 1S, which breaks up below about 3.7 V. Sub250's current listing is titled "Built in with BEC," so buy that revision; older third-party stock may predate it. Oscar tested an original unit; the BEC doesn't change his power complaint. It runs A30. A30 packs are officially supported in BT2.0 quads, but BT2.0 packs in an A30 quad are not, though widely flown; see battery connectors. Whoopindex notes its ELRS is SPI, so it gets ELRS firmware features later than a serial receiver.
Why 1S O4 is a compromise
Oscar calls 2S the O4's sweet spot. On 1S the air unit needs a proper BEC, and BetaFPV's Matrix 3in1 is one of the few boards built for it. If you'd rather run 2S, the Pavo Femto is BetaFPV's O4 option, with its own pack fleet; see Air vs Meteor.
No DJI goggles? Don't buy any of these
Get the analog Meteor75 Pro II from the Meteor75 guide, or go HDZero via the whoop video guide.
