I flew yesterday with my copter and I came up with a very interesting question for my self!!
when my copter was about 0.5m above the ground ,I noticed the battery is low , so I wanted to land but what happened was , the mode changed to RTL , since it was selected for the fail safe mode to do so.
but What it got my attention was that the copter was going higher and higher although I put the RTL_ALT to 50 cm which is 0.5m so it needed not to higher than this ALT. am I right ?
I checked in the param list And I saw the RTL-ALT can be choosen from 0 to 8000 cm . and I had chosen this to be 50 cm before.
now I saw in the webpage of ardupilot the range is showing a number between 200 to 8000cm.
why these two number in param list and ardupilot page is different ? which one is correct ?
RTL_ALT: RTL Altitude
|200 - 8000||1||centimeters|
