Doxilia, Yes sir... the fin is part of the fiberglass fuse.

Alright, I've been looking more closely at this model, and it's never been setup to fly. Oddly, the builder has an airline running into the vertical fin for some reason? Any idea why? And the nose gear is another thing I'm not familiar with. It's beam mount (horizontal) with dual air-up/air down air cylinders to either side of the strut and what seems like a 3rd dummy cylinder in the middle? They're all molded into the plastic frame. I guess this setup keeps the frame as short as possible to fit into tight spaces. What's the age of this style gear?
