How can I ensure repeatable coded flights?
I am very particular about:
-no debris on propeller shafts
-propellers in as new condition
-current on all firmware and software and library
-still air indoor space
-fresh, fully charged battery inserted every time code is flown
-drone bumper is seated properly
-motors have seen relatively little use and seem to be fine, but probably need trim adjustment because even after running the calibration routine, some drones still drift
And what sort of accuracy does a coded flight have (given that no trim is needed)? Can I expect a drone to fly the same course over and over to within say +/- 250 mm or is that unrealistic?
How many minutes of flight time are motors good for, before needing replacement? I am thinking in terms of a preventive maintenance replacement schedule. A log of flights could be kept.,
