max the throws, large expo to start then reduce them a little at a time, creep C of G back till its on the ragged edge.
have fun.

You need a minimum of 45-degrees of elevator, anything less will not force the airframe through the stall fast enough, and instead of a wall you get a snap roll.
Ailerons should be at least 40- degrees and be in the prop wash or you can't stop the torque roll in hover.
If your radio has the ability, mix about 8 degrees of aileron reflex {up} on a switch, this will greatly reduce wing rock in elevators and harriers.
All the rudder you can get, you will need lots of right to hold heading in high alpha anything or the propeller "P" factor will drag you left.
The largest prop your engine can swing, a 12/4 will work better than a 10/6, you don't need speed you need static thrust {think helicopter}, and the larger prop wash area will blanket the control surfaces better.
Adjust all your servo linkage so the servo travel is the max available, this gives both better resolution and more available torque to the control surface.
80% expo on high rates, 30% on low is a good place to start, it will help prevent over controlling until you get used to the huge control power.
Start with a very conservative C.G. it will make it easier for initial trimming.
As you move the C.G. back you probably will need to mix some up elevator with the rudder to stop it from pitching to the belly in knife edge.
This is all based on my personal experience, I have flow a harrier 3-D on several occasions, it's a good plane enjoy it.

There's a video from Wildberry Productions called Electric Flight School.

On the bonus DVD there's a session in a gymnasium featuring Mark Leesberg setting up one of those foamy ultimate style bipes. He gives a ton of information on setting up mixes, trims, and cg etc. That segment is worth the cost of the set IMO. There's a review in the RCU magazine section. http://www.rcuniverse.com/magazine/a...article_id=865
