Brief Description: Cut rudder trim, add control linkage.
I finally got up the nerve to make the final cuts in the rudder trim tab. Once done and cleaned up, it was perfect. The leading edge on the side opposite the hinge was curved inward and then trimmed to clear the control horn and pushrod. The control horn was fabricated and riveted to the hinge side; it is buried in the surface. Then the tab was installed and the linkage set to length before hooking the servo to a power supply and testing the motion. Finally, foam ribs and spar were added to the tab with CyA, to be sealed later for a better bond and painting, Testing showed that motion was full and speed was reasonable, though a rate limiter will be installed in the system to make the trim managable, to be adjusted during flight test. Also, there was some flexing of the skin around the servo mounting, so the foam ribs and spar around the rudder cut-out were not added while I fabricate some foam ribs for the servo area to stabilize that and remove the slight slop that currently exists in the trim.
