Could someone please tell me can I set multiple waypoints to have the same latitude/longitude location but different altitudes? Also, what is the minimum altitude to which I can set a waypoint?
Yes you can, but it takes some effort:
Place all the waypoint you need next to each other with their desired height, then edit/copy the desired coördinates to each of them.
This method works both in the Mission Hub and the Litchi app (you have to enable ‘Show GPS Coordinates’ in General Settings).
Yes you can.
If you use Tribar’s instructions above.
And if you set a rotational angle for every metre increase in height, it gives a good effect.
See the last part of this video from 5:10
although this climb is also set at an angle of 80 degrees from horizontal to continue travelling in the
same direction.
