Does the Vision or the IR sensor measures the height below the craft? Mini4pro IR sensor measurement range: 0.1-8 m. I think it is the IR sensor, so if that is correct how is it possible that the descend speed is reduced flying higher than 8...

Yes, baro height reference to takeoff position. IMO It is not irrelevant to DJI drones for its fly behaviour. Hover at 120 meter and push craft down, keep down stick to 100% all time. Notice that, still above IR range, the descend speed will slow...

Hi BudWalker, Found an better example where a (my) Mini4Pro does not descend with RC down input. In the log from 9m19s , not descending with RC down input. cheers JJB

Hi, Low heights starts above the IR range, max descend is slowed down from approx 40 meter baro height. Fly full speed fwd +100% down stick, my mini starts with 5m/s rate of descend slowing it down to zero just above ground level. Problem is...

Hi, There is much more to this 'not going down' on RC stick down command. See my chart of my own mini4pro. Flying at 20 meters baro height, not much wind this flight. RC down stick and not descending! Drone pitch and roll angles not near the...
