DR-107 One Design R/C plan build, Update #3 

This is a series on building the DR-107 One Design (IMAC) r/c aircraft from the Matt Mrdeza plan. This plan was downloaded from outerzone.co.uk.
In this update, leading and trailing edges are constructed to include adding notches for the ribs. A method of repairing tear out in balsa ribs is shown. Finally, the ribs are loaded onto the wing jig and tacked into position.
