What is Stability & Altitude Mode? How do they Work??

I am currently in the pre-test flight stages of getting my quad up in the air, but I am still a little confused about the setup.

 

My quad is currently mounted to a stand (hasn't flown yet) and I notice that when the throttle is in neutral position both the front and rear motors spin (+ configuration). I am guessing this is stability mode because when I flip my mode switch on channel 5, no motors are spinning on the throttle neutral position?

 

What I dont understand is why are only the front and rear motors spinning in stability mode? Both motors are rotating clockwise, so wouldnt that make my quad spin clockwise as well when it gets up into the air?? How does Stability Mode work and what is suppose to actually be happening??

In addition are all the PID values suppose to be zero in the configurator tool?

 

Also I thought the ArduCopter Project hadn't yet implemented Altitude Hold yet so why is there a Altitude Hold section in the configurator tool? Is this possible with the current alpha code?

 

Any answers would be greatly appreciated.

 

Thanks

just turn it by hand in the direction it wants to turn, you will notice that it will stop turning motors at a certain point
it just tries to stabalize on the yaw axis

Could you please give me a more detailed explanation? What is actually suppose to be happening during stability mode?

In addition, Is the arducopter capable of altitude hold?

Also will the default PID values in the initialize EEPROM work for everyone or do they need to be changed?

Right now all my PID values for both the acrobatic and stable mode are 0 and I know mathematically that that just cant be right!

default isn't zero

the yaw gyro drift a little, so it tries to compensate that, if you give yaw in the other direction it will stop
