To complete the horizontal stabilizers, you continue extruding and shaping them as you did the vertical stabilizer.

Set up the lesson:

• Continue working from the previous lesson.

Continue extruding the stabilizers:

1. Click (Extrude), and then drag to extrude the stabilizer as far as the rectangular flap. Work in the Front viewport but watch the Top viewport.
   
2. In the Top viewport, move and scale the faces in their local Y axis so they match the blueprint image.
   
3. Click (Vertex), then in the Top viewport, move the vertices at the leading edge of the stabilizer to better match the blueprint image.
   TipThis step is easiest if you switch the transform coordinate system back to View.
   
4. Go back to the (Polygon) level, then extrude the stabilizer again, this time almost to the tip.
   
5. On the ribbon Align panel, click (Align X).
   
6. In the Top viewport, move and scale the faces in their local Y axis so they match the blueprint image.
   
7. To shape the tip of the stabilizer, you need a bit more detail in the geometry.

   Go to the (Edge) sub-object level. Click to select one of the longitudinal edges in the widest faces of the stabilizer.

   
8. On the ribbon Modify Selection panel, click (Ring).
   
9. On the ribbon Loops panel, click (Connect).
   

   Now the tip of the stabilizer has seven pairs of vertices, which will help you give it shape.

Complete the stabilizers:

1. In the Top viewport, zoom in on the tip and pan so you have a good view of both the geometry and the blueprint image.
   
2. Return to the (Polygon) sub-object level, and extrude the faces again, almost to the end of the stabilizer in the blueprint image.
   
3. Go to the (Vertex) sub-object level, then use region selection to move vertices so they match the curve of the tip of the stabilizer.
   TipMove the closely spaced vertices at the leading and trailing edges as pairs (actually four vertices, counting top and bottom), then adjust them further in the next step.
   
4. For the closely spaced vertices at the leading and trailing edges of the stabilizer tip, use region selection to rotate the vertex pairs so they follow the contour of the curve.
   
   
5. Click (Vertex) again to exit the Vertex sub-object level.
