The DoMain 4.2 frame developed by GEPRC for unfettered and aerial photography flight is now officially released. The frame is compatible with DJI-O3, VISTA, and GEPRC-RAD MINI 1W VTX. The flight is more stable and flexible when DoMain adopts a DC structure design on the drone arm, the need for freestyle flight can also be satisfied. The unique structure design provides a stable operating environment for the electronic system with less shaking. The fuselage adopts a 7075 aluminum alloy structure design and unique side plate design to accomplish a fresh visual effect. The durable fuselage can protect the FPV camera and internal electronic equipment effectively. The 20mm*20mm and 25.5mm*25.5 FC mounting holes are also compatible with mainstream FCs, and the VTX mounting holes are 28mm*28mm and 36mm*36mm, which can be directly accessible with the air unit. The 9mm*9mm, 12mm*12mm motor mounting holes equipped with a 3.6-inch propeller possess sufficient power output. Two different 3D printed bases are designed for mounting a GoPro sports camera to record every moment during flight. After a host of testing and improvement by the GEPRC team, the Domain frame is made for unfettered flight. We pursue a better flying experience and a more elegant appearance of the long-range FPV.
