Last week we posted our review of the Parrot AR.Drone Quadricopter , an awesome piece of remote controlled machinery with a not-so-awesome price tag -- the thing streets for around $300. Don't have that kind of Skrilla to plunk down on a toy? Maybe you'd be more interested in building your own.
Greg "Grease" Lehman of St. Paul, Minnesota did exactly that and took 2nd place at the 2010 Minnesota State Fair with his wooden DIY quadricopter. Even better, he posted a fairly exhaustive worklog on Instructables.com.
Lehman used a blueprint that came with a Roswell Quadricopter he purchased back in 1999 as his general guide. The end result is a rad home-brewed quadricopter constructed from ash, oak, walnut, and padauk.
