In the previous installment, I described construction details for the fuselage section of the Affordaplane ultralight project. Now let’s look at construction of the empennage and wing assemblies. Remember, this is a plans-only type of build using off-the-shelf materials and tools intended for a novice builder. Keep this objective in mind when reviewing the construction and design details. A complete free video series on YouTube shows each step of this construction.
The components of the empennage (rudder, elevator, vertical and horizontal stabilizers) are all formed from 1-inch 6061-T6 aluminum tubing. These tubes must be bent into their respective shapes, matching template patterns drawn on your workbench. (Use some craft paper for this!) What is the easiest way to form these simple bends? I found that using an electrician’s conduit bender did the job nicely. With a little practice, each tube was formed to the proper shape and then fitted with a gusset to join its ends.
