Experience the cutting edge of digital FPV with the Happymodel Mobula8 O4. This 85mm powerhouse is one of the first micro whoops to feature the DJI O4 Air Unit, delivering the unbelievable clarity and low latency of DJI’s latest transmission system in a package small enough to fly in your backyard.

DJI O4 HD Video with FOV Extender

The star of the show is the integrated O4 Air Unit, capable of pushing 1080p at 100fps. However, Happymodel didn’t stop there. Recognizing that standard lenses can feel too narrow for tight proximity flying, they have equipped this drone with a custom FOV Extender. This widening lens boosts your field of view up to 150 degrees, giving you the peripheral vision needed for confident racing and freestyle.

• Bonus: The kit includes a set of filters (UV, ND8, ND16) designed specifically for the extender, ensuring cinematic motion blur even in bright sunlight.

2S Powerhouse Performance

Don’t let the size fool you. Powered by EX1103 11000KV brushless motors and Gemfan 2023 triblade propellers, the Mobula8 O4 is tuned for smooth, powerful 2S freestyle. It carries the extra weight of the digital system with ease, offering a locked-in flight feel that rivals larger quads.

Advanced Electronics

At the core is the CrazyF405HD Flight Controller, featuring a powerful STM32F405 MCU and a built-in 12A Bluejay ESC. Unlike older generation boards, this FC utilizes a UART Serial ExpressLRS (ELRS) Receiver, providing a more robust and longer-range control link than SPI-based receivers. It also includes a built-in Blackbox (8MB) and Barometer for advanced tuning and altitude hold capabilities.
