Hi, Marco 

I'm find problem about Altitude level. when i will take off my arducopter and connect APM Planner. It have show altitude in negative (-) or under zero. (first connect battery is show altitude zero. and i will alt_hold or loiter about 10 meters but altitude is little up to on the air and HUD in APM Planner is show -10 - 2 meter. I thinking is a bug about altitude barometer?

and have my logs Barometer measurement error.

thank you,

Balloon

I leave here the parameters of my little quad, in my opinion are a good starting point, especially for the sections STAB / RATE / LOITER, with default parameters have never been able to get a good loiter, but with these yes, my videos speak for themselves.

Marco, tried to fly today with the last git version you sent me (GIT_RM_120309)

I was mortified to see the "leans" problem back again and yaw drift (which I've never, ever had before). Log attached.

I thought these had been fixed? 

Haven't flown the newest version you've posted yet.

OK, tried the latest version and it seems fine, but I've lost my trust again a bit so will have to do some more flights to make sure.

Just had a few flights again, yaw is not right - it doesn't stay correctly pointed, it wonders in the hover and in forward flight. Not nice at all

I know dear Graham, I've already reported on the dev list for a long time and at the first fly with this release, nothing new for now, the problem persists... :-(

HI guys,

This morning (Scandinavian time) I downloaded the 2.4.1 from GIT and gave it a try on my quad (3DR stock, APM2).

I did not like it. Acting up in yaw, not as solid in stabilize, and a bit jerky in altitude hold.

I submit the log here, in case it might be of any interest.

I shall admit that I did not make any real effort to tweak parameters (I had a doubt it would help).

Now I revert to the 2.4.1 I pullet of git 28 feb. I cant say it is solid but for me it is at least better.

/ Tomas

Ps. baro sensor only, except last minutes. As you can see then, my sonar setup sucks.
