Hi Steve,

Ok, I thought I could do that. I think the ability to not be able to set a new home position without rearming is a good thought. I had mentioned how I accidentally set a new home position when a mission I flew stopped to far away to see what it was doing. In reaching for the switch as I nervously watched the ship I bumped the switch forward to new home position and I was in real trouble. I finally remembered the heading it stopped on so I could visualize what to do to bring it back in PH.
If your were prevented from doing a new home position when greater than a safe visual distance from the starting point would be a nice addition. I don't really care, it's fine the way it is now. Christof's idea seems fine too or go back to rubber banding.
I totally agree with you! Have same experience as fingering around the switches in rush.
In my opinion the RTH is a real important safety issue, like a panic button (automatic during some rc problems)
and not a quick and dirty waipointsetting tool. I think every pilot looks for a safe takeoff point to start his flight and that should be the RTH point. It doesn’t make sense to set the RTH point fare away from the takeoff point
because in panic or accident the copter should be back in a safe place.
With this in mind, isn’t it better to set the home position automatically at the ground when
recognizing a stable GPS position (perhaps with a fixed for example 5m accuracy ore parameter
driven accuracy) and then indicating this logged home position with permanent flashing the
blue GPS led (pilot has the decision prevent starting without home position ore possibility to
do some indoor flights without GPS). After this initial home position setting it isn’t possible to
change the fixed position before rearming and starting the automatic process again
(OK adding some altitude is necessary - fixed or parameter driven distance)!
Then Christof’s idea is coming up. You only use a 2 way switch to start ore stop RTH action.
Stopping possibility is important thinking about obstacles on the strait way back but not only
stopping, position override to avoid obstacles is important too (in urban areas we have a lot of
obstacles and not the conditions like “in the middle of nowhere” – Sorry Max

).Stopping RTH
then means switching in PH.
Perhaps it is useful to include automatic landing in RTH too, if you don’t want the landing
you can stop the RTH with the switch, landing is avoided and PH is engaged.
I know this thinking is very restrictive and fare away from the actual implementation but I couldn’t
see the need of setting the home position away from the takeoff point and changing it during a flight session.
The possibility to do that takes more risks as benefit.
