Dynaflite DYFA3901 - Manual (Page 24)

leaving only a small portion of the hinge in the
control surface. To avoid this, you may insert a small
pin through the center of each hinge before
installing. This pin will keep the hinge centered while
you install the control surfaces.
Q 8. Install the hinges in the elevator and attach the
elevator to the stabilizer.
Ql 9. Apply 6 drops of thin CA adhesive to both
sides of each hinge. Allow a few seconds between
drops for the CA to wick into the slot.
LJ 3. Lay one of the threaded rods over the rudder
pushrod on the fuselage top view. The pin in the
clevis should be aligned with the hinge line of the
rudder and fin. Using a pliers/ make two bends in
the threaded rod at the locations shown on the plan.
Q 10. Follow the same procedure to install the
rudder on the fin.
Q 11. Reinstall the control horns.
Q 12. Use a T-pin inserted through the tow hook
block from the inside of the fuselage to locate the
tow hook pilot holes. Thread a 4-40 nut onto the
tow hook. Then, thread the tow hook into the tow
hook block from the bottom of the fuselage to the
depth shown on the plan.
Q 1. Locate the two 1/4" x 1 / 4 " x 22-1/2" balsa
pushrods. Mark one of the rods "elevator" and the
other "rudder".
LJ 4. Cut the rod 6-1/4" from the non-threaded
end. Save the piece of non-threaded rod. On the
threaded rod make a 90° bend 1 /4" from the end
of the rod, opposite the clevis.
Q 5. Use the same procedure to make the elevator
pushrod.
Q 6. Lay both pieces of balsa pushrod material
over the plan at their proper position. Mark the
pushrods at the hole location for the metal rods
(approximately 1-1/8" from the end). Drill a 3/32"
hole through the balsa pushrods at both marks (see
step 9).
LJ 7. Cut a groove in each pushrod from the hole to
the end of the pushrod. The groove needs to be
wide enough for the metal rod to fit in.
Q 2. Thread a nylon clevis 20 turns onto both of
the 2-56 x 12" threaded rods. LJ 8. Taper the end of both balsa pushrods as
shown on the plan.
