Happymodel Mobula6 ELRS 2024 (HDZero Eco)
Happymodel
Indoor trainer, longer flight than Race HD
The Mobula6 ECO 2024 is a 65mm 1S brushless tiny whoop — the first built around 's low-cost ECO camera/VTX bundle — putting 720p60 digital video on a 23.2g bare airframe. It's an indoor proximity trainer for pilots flying radios and HDZero goggles.
Retail stock has been spotty, with the model sold out at multiple vendors at once and only limited units remaining at others.
When retail stock runs thin, remaining units have been priced above MSRP.
The full story
The ECO bundle replaces the fragile MIPI ribbon with a plain HD composite wire harness, so the camera-to-VTX link is more crash-durable and easy to re-solder or extend. The receiver is a true ELRS 2.4GHz V3.0.1 unit — not — with WiFi and passthrough firmware updates, giving full ecosystem compatibility and none of the SPI firmware limitations.
It's primarily an indoor proximity machine: the ECO cam's huge 98-degree vertical is made for ripping tight spaces, and it flies noticeably more agile than the previous Mobula6 HDZero. The stock tune handles wind well enough for calm outdoor cruising, though the tops out at 200mW (25/200mW only), which caps outdoor range. Plug-in motor connectors allow solder-free motor swaps.
Video is 720p60 progressive-scan with stable color and none of analog's brightness flicker or static, displaying natively on HDZero goggles including the BoxPro line. The ECO camera itself is a clear step down from MIPI-based HDZero cams like the Nano V3 — a low-cost, analog-grade sensor that benefits from manual settings tweaks (brightness ~45, sharpness ~15) out of the box.
At 23.16g bare it carries a full HDZero digital feed only about 5g over the analog Mobula6 2024, though the ~6.3g digital stack costs some flight time and float versus the 17.8g analog sibling on the same 1S packs. It slots in as an with longer flight time than the Race HD.
Pros & cons
Pros
- Lightest-class digital whoop: 23.16g bare with a full HDZero digital feed, only about 5g over the analog Mobula6 2024
- True UART/serial ELRS V3.0.1 receiver (not SPI) with WiFi and passthrough firmware updates — full ExpressLRS ecosystem compatibility with radios like your ELRS radio
- ECO system replaces the fragile MIPI ribbon with a plain HD composite wire harness, making the camera-VTX link more crash-durable and easily re-solderable or extendable
Show all 6 pros
- 720p60 progressive-scan video with stable color and none of analog's brightness flicker or static; displays natively on HDZero goggles including the BoxPro line
- Stock tune handles wind well and it is noticeably more agile than the previous Mobula6 HDZero; plug-in motor connectors allow solder-free motor swaps
- Cheapest route into digital whooping at $149.99 MSRP — roughly a $30 premium over the analog version
Cons
- ECO camera image quality is a clear step down from MIPI-based HDZero cams (e.g. Nano V3) — a low-cost, analog-grade sensor that benefits from manual settings tweaks (brightness ~45, sharpness ~15) out of the box
- VTX output tops out at 200mW (25/200mW only), capping outdoor range
- Retailer support is split — at least one vendor (Unmanned Tech) only supports the FC/motors and redirects all ECO VTX issues to HDZero directly
Show all 4 cons
- The ~6.3g digital stack makes it heavier than its 17.8g analog sibling, which costs flight time and float on the same 1S packs; no manufacturer flight-time figure is published
