The K12 Max Drone with optical flow location and screen control sounds like a feature-rich drone. Here's an overview of what each feature might imply and what you should look for: 1. Optical Flow Location: This technology uses sensors to detect movement and maintain stable flight, even in indoor or GPS-denied environments. It improves the precision of hovering, making it easier to control, especially for beginners. It likely uses downward-facing cameras or sensors to track the drone's location relative to the ground. 2. Screen Control: If this drone has screen control, it could mean that it comes with a dedicated controller that has a built-in screen or allows real-time video transmission to your smartphone or another device. This feature gives you a first-person view (FPV) experience, useful for seeing exactly what the drone is capturing in real time. 3. Best Drone with Screen Control: Some of the best drones with screen control usually have a combination of features like a high-quality camera, strong battery life, long-range control, and a good stabilization system. Look for key features like: 4K or HD Camera Quality: High-resolution video and images. GPS Navigation: Enhances flight control and return-to-home features. Obstacle Avoidance Sensors: To avoid crashes during flight. Foldable Design: For portability. Long Battery Life: At least 20–30 minutes of flight time per battery. FPV Transmission Range: A range of at least 500 meters for mid-tier drones. If you’re looking for a drone that ticks all these boxes, there are several models from popular brands like DJI, Holy Stone, and Autel Robotics that are worth considering as well.
