In the course “How to Build a Raspberry Pi Drone,” the Manually Flying Your Drone section in a video called Flying in ALT-HOLD Mode. I can’t hold my drone in the AtlHold position after turning the knob to the right (see picture below). It’s very hard to control the drone with the RC after you give it throttle, and the drone keeps moving forward. I followed the Mission Planner settings instructions and could not make it work. Any help would be greatly appreciated. See the pictures below for reference.
