The 3S package with surfice at your current skill level, 4S would probably be a little to "on the edge of out of control", but you can certainly grow into it.
Bring it down this saturday so I can have a good look at it, but I recon Turnigy or Corona MG 929 or 939's will be on the money, I'd go the 929's they are full digital and metal gear and are very fast.
It weighs about as much as a good shirt, so power won't be an issue.
Just looking at the Corona MG 929 servo's, I didn't know about those, They look like a good little unit too. probably better than the ones I suggested.
Basically in a servo for a 3D plane you want everything, speed, power, resolution, good centering and duribility.
At around 2.7Kg cm you should be OK with power, speed is OK at .13, these are the specs if you run it at 6V that's why I'd go for a seperate Bec. If you use this one instead of the one I suggested in my earlier post you can run at 6V and Have 5A

You want a minimum of 5A with your Bec because those servo's need the current to opperate at that speed and with that much torque. If you fly 3D you will work them hard. I know it says the opperating current is 200 to 240 mA but I'll wager the stall current will run much much higher.
I'm suprised that noone has brought Kieran's "Moneyshot" I reckon it's a bargain I would probably have brought it by now other than we need a new lounge at home and every spair cent is going towards that at the moment and a trip away comming up soon as well.
It would be a good one to get and practice with and perhaps put the Eratix aside for a little later.
With 3d models you can't have too many, If you ask me why tho'. The answer is .................. "not telling"
Either way you'll be suprised at how easily a good 3D machine flies and you'll wonder how anyone could ever crash one.
“The knack of flying is learning how to throw your machine at the ground and miss.”
"When once you have tasted flight, you will forever walk the earth with your thoughts turned skyward, for there you have been, and there you will always long to return." ~Leonardo Da Vinci
