"My gut instinct would be to consider a 'failsafe' that decides when to ignore the accelerometers altogether. I understand that this could be problematic... how do you detect intense vibration? time averaging? min/max? And you can't just switch back…"

"i think this guy is right. as soon as your copter started moving (easy to tell by LAT because you were in loiter so long beforehand) your accelerometers are going nuts. Desired X & Y accel is +/-5 (centered at 0) and Z between -5 and -15 (centered…"

"thanks randy! that odroid guide is great. based on the rpi references, i'm assuming the same guidelines will work? I was planning on using an rpi camera module because of its speed and IR capabilities. if you don't think its fast enough, I also have…"

"chris, shouldn't you be off doing ceo things? :P its cool of you to be helping people.

martin, i recently built my first quad and walked through why i picked what i did (along with a few followup posts about why i've crashed and replaced parts).…"

"do you have a legit apm? I've got the rctimer version, and their setup guide explicitly tells you to glue a piece of black foam over the barometer (haha)
very last picture in the first post:…"

"haha, youre making this pretty painful man. just post the log file. i am going to use mission planner to look at the recorded data as outlined here http://copter.ardupilot.com/wiki/downloading-and-analyzing-data-log..."

"Finnius, yes, you are JUST within the limits of what is considered acceptable, but without the logs no one else can check for you.

which tag are you looking at? There are:
CTUN: BarAlt - the altitude from the barometer
GPS: Alt - the altitude from…"
