Nice find, ace. Robotech is awesome. I just might build one of those...
Here's another great B-shelf instructions find: The Spiffcraft from Calvin & Hobbes.

I really recommend building it, it is just SO CUTE. It's also great in a Brkwar, I made a stat card for it.
Speaking of coolness factor, this is my sigfig, in his ceremonial dress cape (For intimidation) epicly exiting a helicopter, in slow motion, the flurries of wind from the spinning blades whipping around, his cape flying and fluttering.
I've had him for years, I originally designed him when I was 6 or 7 (only his torso has changed since then) and he was the boss of one of my first bases, and he's been the boss of every base since the beginning of time... him and his pet kitty! Kitty owns. He has his own personal starship. And he is trained in the art of Kung Fu. And he has built in mini-toast feature! Yay!
