Aerodynamic Tail Feather construction for a Belite
We'll cover both pieces of our horizontal tail assembly in this document: the elevator, and the horizontal stabilizer.
Construction of both pieces is very similar. Please refer to the blue prints for layout dimensional information.
Prior to assembly, all wood pieces are sanded and deburred. Steel and aluminum pieces are cleaned. Steel pieces are also painted, except where glue joints will be. (We cover the steel pieces with strategically placed masking tape, then spray paint is applied.)
Let's start with the elevator. We use 3M 2216 glue to attach the wood ribs to the elevator spar. We also glue tail end gussets to the end of each rib using high quality wood glue.
Now it is time to install the four bolts, one on each torque arm.

The trailing edge is fitted into place. It will fit snugly over the wood ribs and gussets. The trailing edge usually has a plastic film both inside and outside; remove the film.

The wood strips are then glued to the wood ribs.

Next, we'll finish up the horizontal stabilizer.
