About a month ago I decided to build a trainer, but a bigger then usual trainer, well for myself that is.
I started of with my desired dimensions
I wanted at least a 40 inch wingspan, and I wanted it to be able to carry a bit of a load. Another requirement was a low amp power system that would ensure a longer than usual flight time.
I then started to order the parts from HobbyKing
Motor
hexTronik DT750 Brushless Outrunner 750kv
ESC
TURNIGY Plush 30amp Speed Controller
Prop
10 x 4.7 SF Prop
Servos
HobbyKing 929MG Metal Gear Servo 2.2kg/ 12.5g/ 0.10sec
&
HXT900 9g / 1.6kg / .12sec Micro Servo
The rest of the parts I had as spares lying around doing nothing.
I then gathered all the foam I would use and I started building.
After about 18 hours she was finished and I ended up with my new big trainer with a 47 inch wingspan.
I placed a 450 size heli canopy to give you an idea of the size.
I then decided to add some LED lights for some night flight fun
I took it out the next day for the maiden, and was very happy to see it fly the first time without any major problems.
i did a test to time the flight time on a 2200mah Lipo, and the battery lasted long past 20 minutes.
As a whole I am very happy with this build, and I will post some nigtht flight videos soon.
Happy Flying :)

Is it primarily foam board?
Do you use a separate battery for the lights?

I use the same battery I fly with to power the LEDs, it's connected to the AUX channel on my RX so I can remotely switch it on when it gets dark during flight.

That plane looks similar to an Avispad. Is that what you based it on?
I'm currently building an Avispad out of coro for my first plane. Should hopefully be able to get it into the air next week.

No not really, I just started building without an actual plan in mind, I have built so many foamies in my life I took some of the designs I did and combined them. I just had a look at the Avispad and I am amazed about the looks as it looks allot like my build. Thanks for the info.
