Senior Telemaster Build, Tail Feathers (Part 2)

In part one of this series I covered getting set up with tools and such for building the STM along with the initial steps of building the wing. If you haven't read part one of this series, you can check it out here.

In this segment I'll cover building the tail section which includes the stabilizer, elevator, rudder and fin. I started with the stabilizer which is built just like the wing panels where you lay the plans down on a flat building surface and cover them with wax paper. The trailing edge, bottom spar, and leading edge are then pinned to the building board and ribs are installed. A word of caution, the set of plans I received were extremely warped. If I had built the stab by laying the ribs exactly as shown, the stab would have been an inch wider on the left side of the rudder than the right. I had to adjust rib spacing to get the stab symmetrically left and right. Same as with the wing, if I had laid the trailing or leading edges down on the plans without checking for straightness with a straight edge, I would have ended up with a warped flying surface.

Top Planking Glued and Pinned to Center Ribs
Special attention is required when installing the two center ribs so that they are 90 degrees to the leading and trail edge as well as 90 degrees vertically so that the fin will be straight up and down.
