"box" contruction, apart from windows was quite simple to start the body construction. I use 4mm balsa with 1,5mm plywood dubbler. Everything in old classic way. The main problem is allways to avoid that very common "banana" shape, I use a building rig to avoide this and was very easy to to it the right way.
Since it is a scale model I also decided to add some scale features, like the side door, and since the door was there why not use it for something, in this case to access elevator and rudder servos
One of my main porpuses with this kind of airplanes is to use them in most possible situations, so instaed of using it only in the hills and since the original plane was carried, I have decided to get it ready for being carried, here you can see the release servo in place
