In this video, which is said to be one of the best micro multicopter / quadrocopter video tutorial on the web, a detailed description is given how to fully assemble a micro quadcopter within 10minutes. Despite the fact that i do not understand the speaker, the video is detailed enough to easily understand each assembly step. For those of you who prefer to buy an assembled, ready to play Quadcopter, check out the RobotStore gallery.
At this years Ars Electronica technology art festival (Klangwolke), the audience enjoyed the performance of a Quadcopter Swarm, consisting of 50! Quadcopters (AscTec Hummingbirds) synchronized together to fly and form shapes like one single organism, which in fact is a world record. The quadcopters were equipped with led lights in different colors to perform ambient light effects during the motion. The so called ‘Cloud in the Web’ performance was programmed by the Ars Electronica Futurelab and Ascending Technologies GmbH. The firmware of the standard AscTec Hummingbird Quadcopters was modified slightly to enable this synchronized art performance.
Despite the fact, that there are already some Quadcopter and Tricopter designs out there (see Mapmaking Quadcopter, Quadcopter), the creator of this Tricopter accomplished to build a fully functional and quite agile model without spending more than 100$. Even the cheapest Quadcopters cost at least several hundred dollars. His Tricopter design builds upon cheap body parts from a local hardware store, such as a wooden Tricopter body.

Geek.com published another example for a home made Quadcopter design, which by the way looks quite promising according to its agility and flying characteristics. This quadcopter was designed by AliShanMao and published on his website Only Flying Machines. It is able to carry a payload of around 2.3 kg without any major drawbacks in its flight characteristics. Only Flying Machines also published some other quadcopter designs and does ship full quadcopter kits for around 500$ each.
