In auto, at the end of a mission, the last waypoint being land, does not land very near where the waypoint is positioned in MP. This happens every time. Using the 3DR radio, I can see that there is good gps coverage but the quad seems to land 30 meters away from the waypoint. I could not see how close the quad flew to the other waypoints as I lost radio coverage. I would like to get it to land within 5 meters maximum. Is this possible ?

If you configure your Mission Planner to use speech, you will hear "Heading to waypoint sixty five thousand five hundred and thirty five" at the end of your mission.

I have never had a problem with the last waypoint with 2.7.3 , just where the quad actually lands which is around 30 meters from the "land" waypoint.
I tried ending a mission today with your advised 2 "land" commands at the end..... What it actually done today is ignore both of the 2 land waypoints and landed at the last "waypoint" before the "land" commands !
So after sending the quad off on a 3km mission , it never came back. Unaware of what had happened, I used my mobile telephone and rung the tracking unit that I bought (from ebay for around 40euros). It sent a sms back to me with the co-ords of the quad. By then the sky was pitch black, and I had go do a mile walk through fields marshes and woodland. Then from a distance, I saw the APM's flashing lights ! yey ! ...the best 40 euros I have ever spent. It had landed safely 10 meters from the edge of woodland in some long grass..
My new 3dr radio only gives me 300 meters range. This is a separate issue I will be looking at.

So what I do is place a final waypoint where I want it to land and then have the land command after that with no GPS co-ordinates in the command.
It works fine and the landing is within GPS accuracy of the last waypoint.

I will try that next time thanks.

can you supply us with the link to what you got please ?

One piece of advice on these trackers. When you install the battery, it is automatically on. Even if you switch it off, it seems to consume the battery. so I always take it out of the unit when not in use. I have to say, the GPS in the tracker is very good, it finds the location even indoors near small windows very quickly. Much quicker than my Garmin GPS that cost me 400 euros at the time.
The only downfall, are that the batteries are cheap and nasty. One of the two supplied swelled up after one charge, and now does not fit inside the unit. So I advise to search for better quality ones.

I think it's very confusing that when you change a waypoint into a command, the waypoint symbol is left on the map in the planner. Personally, I think the waypoint icon should be removed from the map when you change it into a command. But for now it's not. You just have to disregard the map icons that are your commands (as far as navigation goes....).

This is precisely why building a mission is most confusing.
Why can't someone simply say "go from here to here and do this"?

How do you do this?

I never looked at that page because it starts with "Video" and I don't have a video camera on the copter yet.
Permalink Reply by Boston UAV on September 23, 2012 at 2:32pm Wow, that explains an issue I had last night.
I just happened to stumble on this post, anyone know if there a way to view known bugs with the latest rev? (The bug tracker doesn't suffice IMO - although I review it every so often.) I'd love to be on a mailing list for whatever the latest, stable, release is such that when an issue becomes recognized by the devs an email is sent...
