Hi all,
Having some problems getting my quad (GAUI 330x) to fly autonomously using APM1 (including GPS and Xbee modules from the diydrones store). Flew it under RC control and it was great. Got it out in the field and, using the mission planner(1.1.56), told it to take off to 2m, loiter for 30s, and then land. Instead it shot up to 30m, reached 13m/s, and in (about) 10s came crashing down to earth. Luckly most of the damage was to the fame and the electronics, appear, to have escaped.
My question is how do I keep from crashing again?
To be more specific: could the crash have been caused by my lack of magnetometer, something wrong with my loiter command or land command, or is it something else?
Also, does anyone have an example of the commands needed for a basic auto flight (including takeoff and landing) I can look at?
Thanks muchly,
Jake

Auto Flight Update:
Tried the Alt Hold mode and the Pos Hold mode.
Alt Hold works like a charm. I was able to get an awesome hover and it was a lot easier to fly than stabilize mode; although there were times when the quad would hit the ground. Is this because I set the Alt Hold at to low an altitude?
Pos Hold doesn't work at all. Every time I went into that mode the quad would drift in the same direction (even against the wind) and begin to lose altitude. Any ideas about how to fix this?

John and James,
Thanks for the info. I'm going to try an Auto flight this week. I'll let you know.

New Plan:
I am now planning on getting the quad to autonomously takeoff to 2m and then I'll switch it back to stabilize mode and land it manually. For landing I'm going to manually hover it to 2m then switch it to Auto mode and have it programmed to land as the first command.
Will this work? And will it work if I don't have a magnetometer?
