The cycloidal machine promises valuable military possibilities. Most of the noise of present airplanes comes from rhythmic impulses imparted by propellers to the air. The frequency of the sound made by the cycloidal propeller is too low to be heard. The cycloidal machine may hover over an enemy, silent as the night, while observers take note of movements on the ground. Its mission accomplished, it can speed away to safety faster than any airplanes
This website also has some 2500 model airplane plans, check out http://www.aviationshoppe.com/airplane-plans/index.php

Basic Ultraligh Glider (BUG)
The Goat4 and Bug4, are home built, basic ultralight gliders. Technically these aircraft are ultralight sailplanes, but they are best described as "airchairs", which are simple, slow flying gliders with the pilot sitting out in the open air rather than inside a fuselage.
Monoplaza Autogyro (in Spanish) Unfortunately he no longer puts up plans on his site. Try ultraligero.net
Jetpack - These are plans to make a homemade ducted fan jetpack similar to the one on futurehorizons.net.
