I'm trying to fly a low-level grid while maintaining a stable AGL. I'm using an F450 with the old PixHawk. The copter slowly loses altitude until reaching the next waypoint. I'm considering integrating a sonar sensor, but want to see if anyone has had much experience testing this. I'm concerned that copter attitude will cause problems. Also, this might be a software issue and I don't know if the flight software will make altitude adjustments in between waypoints. Any thoughts?
