Dear Alexander
It's really very nice testing on snow. 
I'll appreciated if you can help me with the ALT HOLD PID configuration
I have a Quad with 10Kv Prop 10"x4.7 - APM2.5 ver 2.9 - The Prop size is ~ same as you.
I setting according to the following interactions
1. http://vimeo.com/56224615
2. http://www.arducopter.co.uk/whats-new.html
On stabilization mode it's OK . The problem is during ALT HOLD
The copter swaying from side to side loses height
Can send me ( drori.f@gmail.com)  the parameters file *.param so I can compere and find my mistake
Best Regards

Hi Moshe,

sorry for getting back to so late.
Right now I'm not in front of my APM 2.5 so I cannot send you the param file.
But I can tell you that I didn't do any changes to the default values. They are just like I uploaded them via mission planner.
The only setting I changed was the radio calibration.
The other settings are complete stock.

Sorry, that I couldn't help you more right now.
If you still want me to send the param file, just say so.

C ya,
