KBDFA S25 Foldable RC Quadcopter — 5G 8K HD Camera, No GPS, Four-Sided Obstacle Avoidance, Optical Flow Positioning, Brushless 1503 Motor

Overview: KBDFA S25 professional foldable quadcopter with no GPS, 5G connectivity and four-sided obstacle avoidance. Designed for aerial photography and easy transport, it combines optical flow positioning, brushless propulsion and electronic image stabilization for steadier shots. Core specifications: - Pressure sensor: Height setting - Positioner: Optical flow positioning - Motor: 1503 brushless motor - Electric regulation: 4000/KV - Image transmission receiving method: 2.4 WIFI - Lens: Self stabilized electronic anti shake lens (EIS) - Remote control battery: AA * 3 to be purchased separately - Capacity of smart lithium battery: 3.7V 2000mAh - Control distance (Free interference and no occlusion): 100M - Flight time: About 15 minutes - Charging time: About 2 hours - USB Charging: 5V - Product size: Folding:14*8*9 CM Open:13*24*9 CM - Take-off Weight: 158g Camera & imaging: - Camera parameters Pixel: 4K HD Camera - Camera lens: Adjustable camera by transmitter 90° - Wifi image transmission distance (Free interference and no occlusion): About 50m - Focal length: 50X - Frame rate: 25 fps - Hand gesture shooting/video reconization: 1-5M - 4K: Video resolution (Front camera) 720*480P Photo resolution (Front camera) 3840*2160P - Front lens is a 480P high-definition WIFI lens; a bottom high-definition optical flow lens can switch angle. Servo pan head increases stability and EIS electronic anti-shake improves image clarity. Flight features & functions: - Fixed height function with height maintaining mode, optical flow positioning and fixed point hold for stable hovering. - Route planning: draw a path on the APP to customize flight routes. - Smartphone APP control with one-key return, headless mode, ascend/descend, forward/backward and lateral flight controls. - Gesture photography, optical flow positioning, brushless motor and long-range capability. Equipped with an obstacle avoidance head that can stop quickly on encountering obstacles to prevent collisions. - Brushless motors provide stronger thrust and extended service life. - Lightweight design: body weight of 144g; helps avoid some national drone registration requirements (many countries require registration for drones over 250g — 158g take-off weight noted above can remove that hassle). - 2.4GHz anti-interference technology and six-axis gyroscope for smoother, more convenient control. Additional notes from manufacturer: - The package references an ultra long battery life variant: 3.7V 2500mah milliampere lithium battery with a battery life of about 12 minutes (see included battery below).
