The removable wings on the Van's RV12 ELSA are convenient for storage and for hauling the airplane in a trailer, and two people can take them off and get them back on in short order. But it's critical to get a good fit during the build process, which is just what the build team at EAA Chapter 166 is doing with its RV12. In this RV12 build video, EAA 166 build project lead Rick Montero and chapter member Larry Anglisano take a close look at how it's done, while also addressing the challenges of assembling the airplane in a limited work space.
