The Mobula6 Lost 2.4g. HDZero Adds 5.6g Back
Quick Answer
Buy the Mobula6 2024 V3 if you want the sharpest 65mm flight performance and already own analogue goggles. Choose the Mobula6 ECO 2024 only when HDZero video matters more than the extra 5.56g of dry weight. They share a size and motor specification, but they are not the same aircraft with different cameras.
The Weight Difference Changes More Than the Picture
Our current V3 listing is the 17.6g analogue model, while the ECO is listed at 23.16g without a battery. That 5.56g increase is nearly one-third of the V3's entire dry mass. On a 65mm whoop, it affects acceleration, braking and how quickly the quad recovers after a tight indoor turn.
Both use 31mm tri-blade propellers, 1S power, an A30 connector and SE0702 28000KV motors. The common parts make the comparison look simple, but the electronics are fundamentally different. The V3 uses a CrazyG473 AIO with an STM32G473 MCU, 5A ESCs, serial 2.4GHz ELRS and a 5.8GHz OpenVTX rated up to 400mW. Its Nano5 camera is analogue despite the 1200TVL label.
The ECO retains an F411-based SuperX HD board and adds the separate HDZero ECO camera and VTX. That gives 720p60 progressive digital video and 25mW or 200mW output, while its 4-in-1 ESC is rated at 12A per channel. More ESC headroom does not cancel the mass penalty; the ECO is the video-first version.
V3 Does Not Mean Every Part Became Easier
The V3's G473 processor, 16MB blackbox memory and four UART assignments give it a newer control platform than the ECO. There is a practical catch: Happymodel removed the motor plugs and uses direct-soldered SE0702 motors. It also uses an SH1.0-4-pin USB adaptor rather than a normal USB socket on the board. We would not buy it expecting tool-free maintenance.
The ECO's HDZero link has a different advantage: breakup behaviour and image clarity are easier to interpret than noisy analogue when threading small gaps. Its 98-degree vertical camera field of view is especially useful indoors. If you already own HDZero goggles, that can be worth the mass; buying an entire video ecosystem merely for this airframe is harder to justify.
What We Would Actually Buy
For pure indoor flying, racing gates and minimum mass, we would buy the V3. It is also the direct choice for anyone using analogue goggles. If you want a gentler 65mm alternative, compare our Hummingbird V4.1 breakdown and Air65 guide before assuming the Mobula6 is automatically best.
We would choose the ECO only for an existing HDZero setup. Both current Mobula6 versions use the same lightweight airframe family, and the Mobula6 2024 replacement frame is available separately.

FAQ
Q: Can the Mobula6 V3 work with HDZero goggles?
A: Not directly as a digital system. The V3 transmits analogue 5.8GHz video; you need an analogue receiver solution compatible with your viewing setup.
Q: Do both versions use ExpressLRS?
A: Yes. The current V3 and ECO listings both specify serial 2.4GHz ExpressLRS receivers rather than the older Mobula6's SPI FrSky or FlySky options.
Q: Which battery connector do they use?
A: Both use GNB's A30 connector and are designed for 1S LiPo or LiHV packs. Check connector condition and polarity rather than forcing a worn or unusually tight plug.
