Here is my mini Skywalker scratch design. It has a 50 inch x 8 inch wing with a KFm2 airfoil, with the step made from 1/2 inch pink foamboard from Home Depot.
PLEASE LET ME KNOW IF YOU HAVE ANY TIPS FOR THE TURNING PROBLEM!
Wing: 50" x 8"
Fuselage Length: 50", 10.5" in front of wing, 12" boom behind wing before the tail starts
Motor: 2212-13, 1100kV and 50 grams
Prop: 10x4.7 APC
ESC: 18A Exceed RC
Battery: 2500 mAh, 11.1V 3S lipo GensAce 25C
Servos: 9 gram
Rx: OrangeRx 6 channel DSM2 compatible
Tx: Dx7se
I might have to build something like this, looks simple and effective.

About the problems hangin' a louie -
Step 1. Hold the prop and put a finger on the back of the tailfeathers - Check your axial balance.
Step 2. Take a look a the plane and how the contols move on the ground. Specifically, the rudder and ailerons.
I like to cut a small sliver out on the sides of my ailerons - So the control surface doesn't 'brush up' against the rest of the wing - If you wing bends, even slightly under load, it can bind up the aileron! Try holding the plane by its wingtips and use the ailerons - this will help aggravate any binding.
Make sure you don't have a lot of slop in the connection between your horns and control rods. try moving the surface with your fingers - Does the rod bend? The the surface move a lot?
Apply some (SLIGHT) pressure against the control surface and try to move it with the transmitter - Are both servos putting out the same amount of power?
Check your transmitter and the endpoints for the servos. Sometimes all those values conspire when you are not looking.
Lastly look to see if your tailfeathers move when you work the rudder. Try the rudder and elevator at the same time. Apply SLIGHT pressure while doing so - Any control rod bend? If the tailfeathers move, some simple BBQ skewers make great bracing!
If I had my bet, I'd think aileron binding as the wing flexes. But please let us know what turns up, buddy!
