Pushrods

Assemble the  Pushrods

fuselage  formers  next to the pushrod guide tubes. Note:

The pushrod guide tubes are intentionally installed so the
tube exits the fuselage on the opposite sides of the
controlling servo. They cross inside the fuselage allowing
the pushrods to run nearly straight,  from the servos to the

control horns, for maximum rigidity. Remove the control rods.

1.  Locate the splined plastic tubing and cut several 1/4"

pieces. Slide at least six of these pieces onto each of the
long pushrod wires and space them approximately 2-1/2"
apart  (do not glue yet). If these  tubes do not slide on
easily, cut them to a shorter length. Note: While installing

the pushrods, position the plastic tube guides so they
always stay inside the pushrod guide tubes.  If the guides
are not tight on the pushrods, apply a drop of thin CA- to
secure them.The guides will prevent side to side
movement of the pushrods.

Trim the Guide Tubes

Glue the Guide Tubes In Place

4. Remove a small portion of the fuselage former using

a hobby knife or round file.  The guide tube should fit into

the former flush to the edge. Do not remove any more

former than necessary or it will be weakened. Use medium

CA to glue the guide tubes into place.

2. Apply masking tape to the fuselage next to the guide

tubes to protect the fuselage skin while cutting. Roughen
the end of each tube with  medium sandpaper. Using 6-

minute epoxy glue the tubes in place. Trim the guide tubes

flush with the edge of the fuselage.

Mark the  Fuselage  Former

3. Temporarily insert the pushrods into the guide tubes.

Lay the pushrods on top of the servo  horns. Mark the

Assemble and Install Pushrods

5. Thread the nylon clevises  onto the pushrods 15 full

turns.  Pliers may be required to  hold the  rod while
threading the clevis onto the rod. Use a piece of cloth to

keep from scratching the pushrod. Install the pushrods into

the guide tubes with the clevises at the elevator and

rudder. Connect the clevises to the control horns and use

the pushrods as guides to mark the control horn locations
