How Cheaply Can One Fly?

How low(cost) can you go and still fly?   That question forms one of the pursuits of the Minimalist Airplane Study Group, hosted by William Rich on Yahoo Groups.  He may have found an answer that leads to several intriguing alternative uses for the type of electric powerplant described below.  Use of model aircraft components leads to a low-cost build, and judicious use of off-the-shelf parts from other hobbies keeps costs low and speeds up the development process. He points to a hack from Laserhacker.com, which uses a motor, controller, propeller batteries and connectors one might find at the local hobby shop.  This assemblage manages to fly a paramotor despite the small size of the motor and the relatively small size of the propeller. The Laserhacker link shows not only several videos (this has to be the most fun per dollar flying machine), but includes the parts list and pricing for everything but the final battery pack.  Components include 3D-printed items …

UAVs, Canine First Officers, and Semi-automated Flight

Dr. Brien Seeley, founder and President of the CAFE Foundation, will speak on “The CAFE Green Flight Challenge Program,” at the Unmanned Aircraft Systems conference at San Diego, California, October 10 through 12, 2012. His talk fits well into the conference’s sub-title, “Opportunities, Needs and Challenges,” and will probably reflect the direction he’s been pointing to with recent CAFE presentations on aerial commuting and pocket airports.  The Green Flight Challenge certainly showed that the nascent technology is capable of giving fast, short-range transport at a potentially economical price. The conference will focus on military uses of UAVs and how to integrate them with existing hardware and systems. Since many military-based unmanneds will be navigating our civilian skies in the near future, civilian pilots and air traffic control systems will be obliged to integrate their resources to allow safe passage through what could be skies crowded with autonomous craft. Governor Jerry Brown recently signed a bill that allows self-driving cars on California highways. …
