Happymodel Mobula 7 O4 - 2S ELRS

The Happymodel Mobula 7 is a compact Tinywhoop drone equipped with the DJI O4 digital video transmission system, providing full HD image quality and supporting onboard recording up to 4K resolution. Thanks to its ducted propellers and low weight (38g without battery), flying it is relatively safe. It is powered by RS1102 10000Kv motors paired with 45mm three-blade HQProp propellers and a 2S battery. Flight control is handled by the Happymodel CrazyF405 HD AIO board, featuring an F405 processor, BMI270 gyro, barometer for altitude measurement, 8MB blackbox memory, 12A ESCs with Bluejay firmware, voltage and current sensor, and an integrated UART ELRS receiver on 2.4GHz with a wire antenna.

Recommended batteries are 2S with a capacity of 450–650mAh and an XT30 connector. The battery bay measures 17x13mm.

This drone is designed for smooth indoor flight. Due to the heavier O4 unit and 2S battery, it is not suitable for faster outdoor flying, as it lacks sufficient power for that use case.
