Finished the stall warning switch assembly and installed it in the left leading edge. Switch was verified to be perpendicular to the wing surface.

Section 19 installs the stall warning access panel, switch and wires. I skipped to this section because Section 17 provides open access to the exact area on the left wing to install the stall warning system. I cut the access hole to be able to reach the stall switch and notched the leading edge of the wing for the stall warning tab that will be directly in the wind flow stream or lack of wind stream. I will complete more of Section 19 later in the build.
