Beetle Airplane
This is one of a series of flying paper airplanes with three-dimensional fuselages. But this particular plane looks just like a resting beetle. Yet, despite having no wing or tail to speak of, it flies quite nicely. The model is folded in half down the centre, with the rudder double-reverse folded inside, right up to the last step, where it pops up into the rounded beetle shape. I have to confess that there are two small pieces of tape holding it together at the front and back, but a small amount of tape is generally allowed in the paper airplane world.

Ta-Da!!
