Nope, no particular scale for this build. Actually, I started the project with the thrusters, simply sticking two Ice-Tea cans together, and it kinda went up from there. Scaling-wise, I guess it's around the 1/8th mark, but it's a rough estimate
It can be broken down, each wing fits in the fuselage and can be removed (though I made the mistake of making the thrusters and lasers NOT removable : turns out it's hard to paint a wing with all those things sticking out and getting caught everywhere...). The canopy isn't glued yet, and each cockpit part is removable in order to be easier to paint.
