I've been having a pretty good time with the new AR Drone 2.0, but there have been two things that have been bothering me.

One the first flight and every flight since then I've noticed During the hover it begins to hover backwards and to the right without my doing anything.  I've placed it on many level surfaces and used flat trim to see if it was because of that, but it continues to persist.  I've read other posts about this problem and it sounds like it might be a little bit of a hardware problem with the shafts or the motor's lubrication.

The other problem is that I lose control of it during flight and it will begin to take off to the left direction relative to the aircraft.  I cannot regain control of it at all and it has resulted in the drone hitting a tree or getting out of range.  It has happened to me 2 times outdoors at 3 feet and 6 feet off the ground and one time indoors.

Does anyone know how I can fix the first problem with the hover?

Has anyone experienced the second problem during flight?

My flight controls are set to Joypad mode and I've owned this drone since 5/19.  I've had about 12 flights total.
