Eachine Cvatar: 3-inch freestyle Cinewhoop.

About the drone

A bright novelty presented in August of this year, the potential of which has already been appreciated by many in the unmanned hobby. The Eachine Cvatar is a 3-inch Cinewhoop FPV drone built on a 142-mm carbon frame with rim-guards designed for ultra-smooth cinematic footage where full-size drones are closed for safety reasons. At the heart of the drone is the top-end F7 flight controller, working in tandem with a powerful 4S / 6S powerplant. By default, it is equipped with an equally powerful analog FPV system, with the possibility of retrofitting DJI Digital FPV system, which together provides endless possibilities for creating the best video content.

Conclusion

Best Freestyle Cinewhoop FPV Drone 2020 in terms of price / quality. The car received good components and excellent factory settings, which at the output provides an exponentially smooth and dynamic flight, especially for the 6S version. We also refer to the advantages of DJI training, which allows you to install DJI Digital FPV system without any "collective farm" modification of the drone, and of course an affordable price tag in the niche occupied.

Both versions performed remarkably well on TATTU 4S 14.8V 1550 mAh 120C LipoTATTU R-LINE Version 1.0 6S 22.2V 1050 mAh 95C LiPoHQ Prop Duct 3 Tri-Blade 3 ″
