The rudder foam is CNC machined before you receive it. Also, each 1″ thinwall square tube is precut. Ensure that the fit is good, sand and square each end of the tube, sand the foam channels and ensure that all parts have been identified. Your rudder assembly will look like this:
The rudder gluing is done in at least two steps. (You are welcome to do this in several steps.) Use gorilla glue. This was our first gluing step for the rudder:
The partially glued rudder assembly looks like this when the clamps are removed:
Now it’s time to make the elevator. Let’s lay out the parts. Note that the only unsymmetrical part is the 4″ tube. It will end up being on the *right* side of the elevator; so this assembly is upside down:
We’ve saved the easiest part for last: the horizontal stabilizer. Each of the three parts is glued in place. Before gluing, ensure that the spacing is exactly centered with a 1″ gap on the rear cross spar. This 1″ gap will allow the rudder post to fit through.
After the glue is set, all 3 assemblies are cleaned of excess gorilla glue, sanded, and then spackled:
To be continued.
