I need a little tuning help.. If someone else is using a Arducopter Quad pretty much stock, with using the BETA 3.0RC5 with good results, I'd like to see your PID settings.
I recently flashed the 3.0rc5 on my apm 2.5 in an arducopter quad that is pretty much stock, other than maybe a little heavier than some, having a 3s, 5000 MAH pack.
What is happening is that it is stable in stable mode and works well in loiter until I want to descend. when descending , it wobbles violently. I am used to the fact that any quad I've had seems to wobbles when descending straight down in the prop wash, not so much in forward flight but this is different. I absolutely can't descend without excessive wobble even when in forward flight.
When I first loaded 3.RC5, I had a lot of wobble in loiter. I noticed that my Loiter Speed P values was at 5.000. I saw someone else's set to 1.000 so I tried it, I reduced it to 1.000 and it loiters nicely now. IT just doesn't descend without lots of wobbling.
Here is a screen capture of my settings: Also, the tlog from a short test flight is below the image

Tanks in advance for anyones help!

This video helped me get my quad tuned pretty well, I still get some wobbles descending straight down, need to tune "I" more, I'm just lazy lol, but the video will give you a good idea what does what: https://www.youtube.com/watch?v=PHFSLFlTYH8
I too just loaded V3 rc5 on to both of my quads with apm 2.5 boards. So far I am liking it, but the loiter for me is hit or miss, one time it will loiter perfectly, rock solid, then the next time in the same flight it will start slowly ascending non stop, well until I switch back to manual mode. I just ordered a telemetry kit so I can get a better idea what is going on when this happens.
