"apm 2.8 is not supported much anymore.  You would be better off getting a Pixhawk type controller.  However, everything you need to know is in the Rover Docs."

It's all here."

"I think you can set home position in Mission Planner."

"So a Loiter " flight mode " does not exist yet?"

"It's a mode of operation just like Manual, Learning, Steering etc.  Or I would assume it can be programmed into a mission on Mission Planner.  Try Ardupilot.org."

"The latest Rover code supports this.  I'm still using 3.0 because it suits me just fine.  Latest code I believe you set a Loiter radius around a waypoint and if the "vehicle" leaves this radius it will go back to the Waypoint.  So there may be a…"

"Also, if your mark is round its behavior in the wind and waves will be totally different than a boat as shown in the video.  Try Ardupilot.org and post on the forum.

"There is a Loiter function now.  I have not used it yet.  I guess it depends on how much your mark is allowed to move to achieve the purpose of it."

"Adjusting the parameters in mission planner should solve your problem."

"Tlog will be on your computer if you have flown while linked to Mission Planner via Telemetry.  You can then graph your acc x,y,z vibrations.
INAV_Z will be in the full parameter list on Mission Planner.
Honestly don't remember if 3.2.1 is OK with a…"

" Also a number of autonomous test flights can be watched on youtube.  SWF Drones is the channel name.  Did a ROI that worked out very well as a test.  3.2.1 works very well once everything is set up properly."

"I have not tried simple mode.  I fly a 600 size Heli on 3.2.1.  Low head speed, spin blades, and a bit of weight with the various payloads.  You need to check your vibrations on the z axis to make sure they are not to high.  A log with mission…"

"I run mine at .3 .  Try it with more altitude and be ready to switch back to stabilize and hit the collective.  It could also be some other parameters or a vibration issue.  Post a log and parameters and I'll have a look.  Ardupilot.org may be a…"
