The Mazerati
In spite of this, the long, thin rear wing will vibrate heavily once the plane reaches full airspeed. As with The Firebird, this seems to be a product of a stable flight. With enough experimentation, and/or precision engineering tools, a fully aerodynamic version could be produced...but what's the fun in that?
If these designs interest you, I encourage you to experiment with them. Each model has unique design features that can be mix-&-matched, and infinite variations beyond that. Experiment with different materials: interesting models could be constructed with cardboard, heavier-weight papers, wood, or even plastics.

Firebird
The Firebird is an early model of my "Flying Biplane" prototype. It is light and angular, and an amazingly friendly glider. The "hammerhead" front stabilizer lends another plane surface to modify, and more importantly, it looks pretty fucking cool.
As with the Phaeton model (and the forthcoming "Mazerati" model), it is constructed from a single sheet of 8.5x11 copy paper, and a small piece of scotch tape.
Unlike the Phaeton, this model has no stabilizing fold on the rear wing. This causes the rear wing to be much more flexible, and you will notice that it vibrates during flight. This seems to be a self-regulating property of the craft's design that allows for a straight, linear flight. Compare Firebird's flight path with Phaeton's.
One last note: this craft was constructed before I began incorporating the landing-gear assembly that is prominent with other models. If you choose to incorporate a landing-gear assembly on The Firebird, be sure to compensate by modifying the Center of Gravity.

The Phaeton
IT ALL started about twenty years ago, when, in my rebellious early teens, I decided to give the finger to the popular notion that a "paper airplane" necessitated a sleek, aeronautical "dart" design. An experiment in minimalism revealed that a plain sheet of paper, folded down the middle with a few folds on the front end, made for a beautiful glider when dropped from any substantial height. From there, the fun began:
My "Flying Biplane" prototype emerged from a desire to design the most awkward, unwieldy plane that could possibly achieve flight. The "Phaeton" model presented here accomplishes this nicely.
This model presents some solutions to the initial flaws of original designs. Paradoxically, these "solutions" present problems of their own: The most obvious is the stiffening fold on the leading edge of the rear wing. This keeps the rear wing from destabilizing in mid-flight. But, it turns out that the vibrations of the rear wing are actually a product of a stable, linear flight. By stabilizing the rear wing, this craft compensates by performing a sliding, yawing flight that is not altogether unpleasant or undesirable. The Phaeton is an interesting craft with infinite possibilities. Please let me know of any improvements/modifications you might discover.
I will include links to the original patterns for my designs as I post them, but I would encourage anyone who happens across this blog to post your own models.
