the dcm experts should look at:

spiraling down

even the lightest wind can cause problems.

the heino suggestion to lower the kp values for dcm is not good for us but for:

it never rains in southern california

Robert, I believe he cut the throttle after getting blown out of range.

 

Jeff, Can you plug it in and see if the imu test still works? Also, the adc test in the CLI would be helpful.

Also, did you set a value for Loiter radius using the Mission planner?

That flip was really mysterious...

I saw the IMU offset values didn't print correctly in your CLI dump. That makes me think they were corrupted. If anyone want to help debug this, PM me. I can show you where to look to confirm it. I just don't have HW here at work.

Jason here is the CLI test for IMU and the new setup show.

first test was still, 2nd was I was twiching it

IMU test

setup "show"

After this test I noticed something weird, on CLI mode (switch to CLI) the LED on APM is always green as long as I can remember it will always stay green even after doing anything. Now once you execute a "IMU test" it will go to RED and stay red until APM is rebooted or close/re-open CLI session.

"position" mode
Anyone knows how it works?

Comment by I.S. on November 4, 2011 at 7:44am

The Wiki is the answer:
http://code.google.com/p/arducopter/wiki/AC2_PositionMode

Thanks and sorry for not to look for well enough in the wiki.

Btw, a sugestion for a new mode could be a loiter but when you move out the position using the sticks, it remain loitering in the last position after releasing the sticks.its like guided but using stiks to find the new position,instead of the MP

Developer Comment by jasonshort on November 4, 2011 at 4:04pm

That's actually how it will work in release, once testing is finished. One day.

I have been flying 2.0.50, from git this afternoon,  for over an hour on my new y6 50cm m2m,12x38sf apc props top,12x45 epp props bottom,2831-11motors,1500g auw with gopro and 4500mah 30c lipo.  Very nice alt-hold with my unfiltered LV-EZ0 sonar up to 8ft with no pulsing at all.  After 8ft it pulses (fast)  up and down about +/- 1ft but slowly climbing.  I am getting 13 minutes from the nanotech 4500 30c lipo.  I do not have my baro, as a test, covered but I have a tight fitting polycarbonate dome over the electronics.  It can breathe thru the velcro.  Yaw control is excellent.  I mean dead on.  I did calibrate my compass the ardupiratesNG way though. After reloading code this afternoon with arduino I armed the copter and spun it in all directions then I un-armed.  My mag is mounted underneath the gyros/accels with foam tape and it does not seem to jitter as much as the mag on my other apm which is mounted like the wiki.  I have not enabled the new accel_alt_hold code yet though.  Flying stablize on this windless night I could keep my hands off the tx for 10 secs or more and just give minor nudges to keep it in one spot. Very Nice!  Thanks!
