mini-z ma-010 awd questions...

[94exa2]

sup guys, i dont know much about the z, yet, but was looking to get one soon and have a few questions

first, are the ma-010 awd z's 2.4 ghz? or no?
is there any differance between the "regular" awd and the "formula-d" other than the tires?
are the uni. swingshafts that come in these plastic or alloy?
do these come with bearings anywhere in the chassis or all bushings?

lastly does anyone know where to get the blue r34 readyset anymore(new)?or even just the blue r34 body(new)?

sry for the dumb questions, and thanx in advance guys!
