Wing Incidence

After the stabs and wings are finished and the control surfaces have been set at neutral, it's time to set the wing incidence. I use the molded in dots on the fuselage to level the plane. The wings dots align at 0.5 deg positive incidence. The stab is set at 0 deg incidence. Also I use two 1/4" balsa pointer sticks to make sure there is equal deflection up and town on both elevators.

Be carefull of the brass threaded couplers used on the 0.07" CF push rod. When I making an elevator clevis adjustment, the threaded portion of the brass coupler broke. Fortunately I had some Central Hobbies 4-40 titanium rod ends. I had to cut off the old brass coupler and splice in the titanium rod. The Chip Hyde horn clevis was drilled and tapped for a 4-40 thread. I intend to replace the other elevator brass coupler. The splice is black thread wrapped tight and fixed with thin CA.

The next step will be setting the batteries for proper CG location.
