Part 4d - Rudders and associated hardware (continued)

	Here is a top view of the rudders - painted Ultra Flat Black.
Here is a another view of the rudders. The top rudder has a piece of tape covering the light lens while painting. This will, of course, be removed later.
	I designed a mechanism to ensure linear servo rod movement and used a 3/64" brass rod. It was flexible enough to bend but strong enough to withstand the pressure of the servo/rod movement. The two brass rods (3/64" and 1/8") were soldered together on the ends. The smaller rod was then bent to shape and attached to the servo horn itself. When the rod travels forward/aft, the smaller rod bends inward, but the 1/8" rod remains straight. The result is no binding in the BHS seal.
Here, you can see that I´ve manufactured and installed a coupler instead of having one continuous rod. This enables me to adjust not only the length of the rod, but also the sideways travel as well. It also provides for easy removal of the WTC and the propeller shafts if necessary! The coupler was made from a piece of brass sheet and a 1/8" Dura Collar. The collar were first soldered to the brass sheet. Next, a hole was drilled through the brass sheet matching the hole in the collar (1/8".)
