This is a series on building the DR107 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 started. A problem with the plan set is discussed. A neat feature of former alignment is shown. A couple of parts are laminated from lite ply and carbon fiber. I discuss consideration for access to the motor battery.
