A Close Look at the Mobula 8 with DJI O3:
The Happymodel Mobula 8 DJI O3 Cinewhoop features an 85mm frame, making it slightly larger than the standard Mobula. It comes equipped with the Crazy F405 HD flight controller, specifically designed for compatibility with all HD digital FPV systems such as DJI, Walksnail, and HDZero. The flexible plastic canopy is injection-molded, ensuring durability even during minor crashes.
One notable feature of this model is the ExpressLRS UART receiver, which differs from the SPI receiver found in the analog version of the Mobula 8.
Weighing approximately 82g, the Mobula 8 with DJI O3 strikes a balance between weight and agility. When paired with a 2S 450mAh LiPo battery, the total weight reaches around 109g.
However, there are a couple of design aspects that require attention. Firstly, the lack of support for the DJI O3 antennas may result in entanglement or damage caused by spinning propellers during flight. Secondly, accessing the USB port can be challenging without disassembling parts of the drone, particularly when downloading footage from the DJI O3. Including a right-angle adapter in the kit would greatly improve accessibility to the USB port.
Flight Performance:
Designed primarily for calm weather and indoor flights, the Mobula 8 showcases its versatility and responsiveness, delivering a solid performance across various flying styles. Compared to its smaller counterpart, the 1S Mobula 7, the Mobula 8 offers a more enjoyable outdoor flying experience with its impressive power and agility. Outfitted with Gyroflow, it maintains stability even in gusty conditions of up to 15MPH, allowing for smooth footage capture.
In calm weather conditions, the Mobula 8 with DJI O3 provides a flight time of approximately 3:00 to 3:30 minutes on a 2S 450mAh LiPo battery, or 4 minutes on a 2S 550mAh battery (mix of freestyle and cruising).
It's important to select a battery that fits the drone's battery holder. While larger batteries may provide extended flight times, they also add weight, which can impact the quad's agility. Consider your flying needs and weigh the pros and cons accordingly.
Durability:
The Mobula 8 demonstrates good durability, withstanding crashes reasonably well. However, based on experiences with this model and its predecessors, the frames are prone to breakage under heavy impact, particularly when accommodating the DJI O3 Air Unit's additional weight. This is not a major issue but worth considering when purchasing. It might be wise to have a spare frame on hand for potential repairs or replacements.
Another area of concern lies in the exposed O3 camera. While the camera protection offers some level of safety, the lens remains susceptible to scratches or breakage upon impact. Fortunately, the video transmitter module is well-protected.
Consider investing in an ND filter or, at the very least, a UV filter that can double as a lens protector.
Mobula 8 vs Pavo Pico:
If you're considering small cinewhoops capable of carrying the DJI O3 Air Unit, you might be comparing the Mobula 8 with the BetaFPV Pavo Pico. Both models have their strengths and weaknesses.
The Pavo Pico features a more refined and compact design, while the Mobula 8 stands out for its raw power and agility, despite their similar specifications. It's important to note that the Pavo Pico is smaller (80mm size whoop) compared to the slightly larger Mobula 8 (85mm). The Pavo Pico weighs approximately 10 grams less, but the Mobula 8 offers more power thanks to its
motor and propeller combination.
If you prefer a tiny drone for relaxed cruising or cinematic flying, indoors or outdoors, both options would serve you well. However, the Pavo Pico's user-friendly design and accessories might make it a more appealing choice. On the other hand, if you prioritize power for outdoor freestyle flying, the Mobula 8 could be the better option.
Conclusion:
In conclusion, the Happymodel Mobula 8 with DJI O3 is a highly capable and versatile micro FPV drone. Its performance across different flying styles and conditions is impressive. While there are design elements that could benefit from refinement, considering its price tag of $390, it remains a solid choice. The powerful motor and propeller combination, along with its compact form factor, provide a compelling flight experience.
