I finally had some time to finish the elvator pushrod setup.
Only one center support was needed. There is about 26 inches between the servo arm and the inside support at the fuse exit. The support was placed midway between. I decided that one support was enough when I was unable to get the pushrtod to flex with manual pressure on one end. The support was made from a piece of 1/8" end grain balsa fiberglass laminate. The guides were made from small pieces of teflon tubing with 1/8" grooves cut in the center at a slight angle to match the pushrod angle (2 degrees or so). This was my reason for using the thick walled teflon tubing. The support was made in 2 halves to entrap the groove of the teflon bearing. The piece of teflon could be rotated to match the angle for the smoothest movement. After I was happpy with its position it was glued in place. To help position the central support I made a temporary foward support This was placed before the central support in direct line with the pushrods and elevator horns.

Once the central support was in, I made the elevator servo tray. This was made from carbon fiber nomex 1/8" plate. The servo was attached with BVM right angle servo mounts and positioned before gluing the plate in place. Lightening holes were cut as well. I choose to use dual ball link attachment at the servo arm instead of combining the pushrods into one. This way the pushrods can still be removed from the plane if ever needed by just removing the ball links from them.

The pushrods with ends and guides added 27 gms to the plane. The elevator servo tray an additional 7 gms.
