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, construction of the fuselage is continued. The empennage stringers are constructed and the fuselage bottom is sheeted. A comparison of several different types of stringer construction is discussed before adding them. The fuselage is broken free from the build table to accommodate adding the stringers. The design consideration for the bottom stingers and bottom sheeting is discussed and how it relates to the full scale airplane. Acetone is tried to debond a stringer for realignment. Horizontal and vertical stabs are given a cursory alignment check and bottom sheeting is applied. Forward fuselage sheeting is applied using Gorilla Glue polyurethane glue.
