RE: 52
Dude ... the motor is WAAAAAAAAAAYYYY too hot! KV amazingly too high. Let's say your plane is 1 kg and with the motor etc it would be about 1.75 kgs and you want to fly her scale.
Motor - something in the 450W-500W range ... try the DualSky 3542 or 3548 series ... AXI 2820 series ... Hyperion 30XX series and other which are the same.
Batt - 3S 2,200 to 3S 2,500
ESC - 40A
Prop - 11x8 to 12x8

RE: 52
Scale flying means to fly like the real thing. That would basically mean she will not give you vertical flight like the Space Shuttle ... 
What is the weight of the bare plane, plane alone without MOTOR/BATT/ESC but with servos and UC adn wheels etc. We can estimate from there.
