im trying to build a cheap fpv drone, a possible frame would be the source one V5, for FC and ESC maybe a G4 porcessor? but i havent decided yet, idk which motors to choose, possible propellers are gemfan hurricane 51466, id prefer 4s LiPos, i would replace the fpv camera, vtx and antenna with the dji o4 air unit lite costing 115€, i already have the dji flight controller 2 and i d buy the dji gn3, idk which charger to choose. could you look for products resulting in a compatible light and budget friendly fpv build. you can orient yourself at the iflight nazgul evoque f5 v2 o4
