Section 15: Installing the Control Linkages
Step 5. Drill a 1/8" hole at this mark. This end of the hardwood
dowel will be used as the pushrod end for the split elevators.
Two of the 12" threaded rods will be installed at this end.
Step 6. Locate the two 12" threaded rods. Using a needle nose
pliers, bend a 90 degree angle at the opposite end of the thread-
ed portion of each rod. The bent section should be 1/8"–3/16"
long. Cut off any excess material so the rods will fit into the
holes of the hardwood pushrod without the ends extending out
of the hole on the other side.
Step 7. Using the pattern shown below as a reference, bend the
two threaded 12" rods the approximate angle the diagram
shows. These are only approximate, final adjustment will be
made when fitting the control rods to each elevator control horn.
Step 8. Trial fit the two 12" threaded rods into the holes on
either side of the wood pushrod. We highly recommend you cut
a groove for both to help secure the rods. You may also need to
bevel the hole so the wires fit flush to the hardwood pushrod.
Step 9. Once you're satisfied with the fit, mix a small amount,
approximately 1/4 ounce, of 12-minute epoxy and apply it to the
holes and areas the rods will fit into. Coat the joint with epoxy and

slide a piece of heat shrink tubing over the end of the wooden
pushrod end. Allow epoxy to cure, then using a heat gun, shrink
into place.
Step 10. Carefully cut away the covering at the tail of the fuse-
lage where the pushrods exit. Note there are two cutouts on each
side. The ones closest to the horizontal stabilizer are for the ele-
vator pushrods to exit. The ones farther away from the horizontal
stabilizer are the pull-pull rudder cable exits.
