Design, Construct, and Options

The Caddx Ratel Professional maintains the traditional 19x19mm type issue however distinguishes itself from the Ratel 2 with a very new design. The Professional model boasts a metallic case, enhancing sturdiness and serving as a warmth sink, albeit including an additional 4 grams—weighing in at 9.5g in comparison with the Ratel 2’s 5g.

That includes a big 1/1.8-inch picture sensor, comparable in measurement to the discontinued Runcam Eagle 2, the Ratel Professional guarantees superior low-light efficiency attributable to its skill to seize extra gentle. The digital camera claims to ship excellent picture high quality with a minimal illumination requirement of 0.00001 lux.

Nevertheless, the Ratel Professional’s lens is notably longer than that of the Ratel 2, doubtlessly complicating mounting and safety. A notable downside is its 125° subject of view (FOV), considerably narrower than the extra widespread 160° FOV present in fashionable FPV cameras just like the Ratel 2, which affords a 165° FOV. I believe FPV drones profit from the broader subject of view particularly when flying proximity and navigating although tight areas. Subsequently this narrower FOV would possibly restrict its attraction to FPV drone pilots accustomed to a wider perspective.

The Ratel Professional helps switchable 4:3 and 16:9 facet ratios, switchable within the OSD menu utilizing the offered joystick. It may be powered by a large voltage vary from 4.5V to 27V, accommodating 2S to 6S batteries direct energy.

Maybe a tiny bit oversharpened to my style as you possibly can see some digital artefacts within the branches, luckily sharpness could be adjusted within the settings. In distinction, the Ratel 2 produces a softer and fewer contrasty picture.

The diminished FOV of the Professional was instantly noticeable and considerably limiting for FPV drone flying, doubtlessly making it extra appropriate for prime altitude flying resembling fixed-wing plane. Nevertheless, the diminished “fisheye” distortion and extra correct depiction of distances had been optimistic facets.

Evening Efficiency

Historically, cameras just like the Runcam Evening Eagle 3 have set the usual for low-light FPV flying. They excel at nighttime, because of their excessive sensitivity to gentle. Nevertheless, their efficiency underneath the brilliant solar leaves a lot to be desired. That is the place the Ratel Professional steps in, promising one of the best of each worlds: vibrant shade in the course of the day and excellent evening imaginative and prescient.

Due to its giant picture sensor and enhanced algorithm, the digital camera’s low-light efficiency was spectacular, providing clear and crisp imagery the place the Ratel 2 struggled with graininess and noise.

Conclusion

The Caddx Ratel Professional is a step ahead in analog FPV digital camera know-how, excelling in each daytime and nighttime circumstances. Nevertheless, its slim FOV could possibly be a deal-breaker for a lot of drone pilots. Whereas it might not dethrone the Ratel 2 for FPV drone personally, it might discover its area of interest amongst pilots flying at larger altitudes or in functions the place a narrower FOV is appropriate. For these in search of a flexible FPV digital camera able to performing nicely day and evening, the Ratel Professional is value contemplating.
