Hello all. I have my quad flying stable right now. I am working on getting missions to work through the apm.
I click on the flight planner and set a "Take off" event to 10 (meters right?).
I then have it land. I write the way points to the quad.
I go out to the field to test it. I flip the switch into GUIDED MODE which then the quad takes off like a bat out of you know what. I have to flip it into manual mode to bring it back down. The first time I did it... It reached 92m before I tried to bring it back down...
I guess what I am really in need of is how should I be doing this? When on the ground my quad reads about 1m. Is there any "gocthas" that I am missing. Settings here or there? Also, is there a way to slow down the quad a bit in mission mode? This is the last real thing I need before I think the thing is done. Just was hoping for some veteran support.

I think you should use Auto mode, not Guided.
From the Wiki :
"Guided mode works in a similar fashion to RTL, except the target location can be set by clicking on a map. Once the location is reached, the copter will hover at that location, waiting for the next command."
Did you cover your baro with a small piece of open cells foam (see that advice in the wiki) ?
Did you fly without protective dome like on the picture ? If you did this, there are some chances that your baro did receive overpressure, and it did think that you was lower than the real height because of the ascension speed causing a quite high overpressure on it. Try to breath on it, you will see that it is very sensitive.
You should try Alt_Hold at altitudes from 2m to 20m and see if it is rock solid before to try missions.
I would not try auto take off and auto land without sonar. Baro precision is only about +/- 50cm - 1m.
Auto Land seems quite dangerous to me, it should be considered as an experimental or recovery feature.
You can test the baro sensor from the CLI test menu.
The normal mode for missions is AUTO. GUIDED is when you wanna click 'go here now' in the mission planner during a mission.
It also helps to indicate which version of arducopter you are using.
Make sure your baro and/or sonar are working ok (you need rock solid althold below and above 10m before you try missions)
