hey i am planing on buying the ArduCopter 3DR and i would like to know a couple of things
A. how stable is it
B. do i need to buy anything else
C. what specs should the li-po be
D. if the 880 KV motor was designed for a 12x45 prop. why is there no option for that prop when adding it to the cart?

I don't have a 3 DR. The propeller to motor(s) at a given weight combination determines how well it will fly with a given power distribution, especially batteries and how well they can push current. Lower resistance with light weight rules. Possibly look up http://www.ecalc.ch/xcoptercalc_e.htm?ecalc
I'm in the same boat as you. Not sure which motor - prop to start out with.
I also plan on doing allot of experimenting with the user code section and adding weight to the frame, I know this frame is heavier but I'm more comfortable with this design.
