Arducopter more sensitive on fresh battery?

Hey guys,

I've got my ArduCopter dialed in pretty well in acro mode but I'm seeing one oddity. When I put in a fresh battery and begin flying it seems like the copter is much more sensitive to commands and the tendency to oscillate in level flight is much higher. It's almost to the point where I want to go tweaking PID values again, but as the battery begins to drain (long before it dies) the copter becomes much more stable.

Is this just the nature of the beast or am I missing something?

Thanks,
-Chri

And also what software are you using for your ArduCopter due there are several softwares out there and they all are rather different.

Ive noticed the same - but I just figured that when its a fresh battery, its also a fresh operator and im a little bit touchier on the sticks earlier on.
