Brief Description:  End-to-endtesting of the trim tab servo

With all the mechanical elements now ready, it was time to test the trim tab servo "throw" to full travel in either direction.

The first thing to do was to cut the servo actuator rod to the correct length, and this was identified by first setting up the servo itself to its mid position, and then finding a length of rod that would put the tab in trail with the elevator at that point.

Once the rod was cut, and clevis pins attached at each end and connected to the tab horn at one end and servo arm at the other, the next step was to run te servo in both directions and check for any mechanical fouling on the structure.
