a question about RTH.....I have not used it yet.....does the drone return to the spot at the height that I would set...then come straight down?....or does it come down from a distance?...I ask because I watched a video in which the guy sent his drone across his relatively flat country town.....about 2 miles.....on return he mentioned that he engaged RTH, and was showing his screen and it seemed that the drone was descending as it approached its destination
Yes, it comes home at the preset altitude you put into the settings (important to do this for each flight for obvious reasons).
If the drone is HIGHER than the RTH set, it will stay at that height until it reaches right above the take off (home) point, then descend to land.
This is good where you fly up a hillside, and often can exceed RTH setting, so it stays up there.
Can also be dangerous as the closer to home, the higher from ground level you are, where there is often more wind speed. (See below re taking over / overriding.)
That example you put might have been a situation where he was flying over lower land, and as it came home it seemed to be dropping altitude.
or....are you able to control altitude as it approaches you when using RTH, while continuing on proper path home?
Yes
You can use the left stick to drop descent if you see you are too high, if the ground is level and no trees, drop it as the drone flies home itself.
Release stick when it suits, and raise it if necessary of course.
You can also easily cancel RTH if you want to fly it back at any point, wither click the cancel RTH on the screen and confirm that, or push pause, or put into sports mode.
You can cancel failsafe RTH (low battery) but best to not really let it get that far down in battery %.
Be aware of letting it go low battery RTH, wind against the flight home sees lots of drones lost.
