Dynaflite DYFA2016 - Manual (Page 28)

Back to the fuselage for a little while. It will soon be
time for covering!
Q 1. Cut two 1 /4" x 4" strips from leftover 1 /8"
plywood. Glue them together with medium CA to
make the servo rails.
U 2. From the strips you glued together, cut two
servo rails that will fit between the fuselage sides in
the servo compartment.
0 3. Position your servo(s) on the rails in the fuselage
as shown on the plan. Raise or lower the rails so the
servo arms (or wheels) will align with the pushrods but
make sure the servos will not interfere with the
forward wing dowel. There is enough room for
standard size servos but most advanced fliers will use
mini or micro servos for the least amount of weight.
1— 7. Use silver solder to solder a Great Planes
Standard Solder Clevis (not included with this kit,
GPMQ3810) onto the elevator cable (included with
the Great P l a n e s F l e x i b l e Cable Pushrod set
previously recommended). Connect the clevis to the
second or third hole of a small nylon control horn
included with this kit.
Q 8. Route the cable through the guide tube and
position the control horn on the elevator as shown
on the plan.
LJ 4. Make sure there is enough space between the
rails so you can remove the servos. Glue the rails to
the fuselage sides with medium or thin CA.
Q 5. Mount the servos to the rails with the
screws, grommets and brass inserts included with
your radio system.
Q 6. Cut the elevator and rudder (if you have a
moveable rudder) guide tubes so they extend
approximately 1 /4" forward of bulkhead C.
U 9. Use the control horns as a template to drill two
1/16" holes to mount the control horns to the rudder
and elevator with 2-56 x 1 /2" screws in the location
shown on the plan. Connect the rudder pushrod and
elevator cable to the control horns.
Q 10. At the servo end, cut the elevator cable and the
rudder pushrod to the correct length. Connect them to
the servos with your favorite type of connector. On our
prototype we used Great Planes Screw-Lock" Pushrod
Connectors (not included, GPMQ3870).
