RETRACT SERVO INSTALLATION
58.Secure the retract servo tray in place with four 2.3x8mm
washer wood screws.
59.Trail fit the two wing halves and join them with the
fiberglass tube.Insert the fiberglass tube into the fuselage,
center it,then thread the retract gear pushrod and aileron
servo wire to go through the fuselage which are pre-drill in
factory and slowly join the wing halves until it makes
contact the fuselage. Never push too hard as it may
damage the tube-stop rib inside the wing panel.
60. Locate the hole that is located at the bottom wing just
right above the fiberglass tube about 4 1/2" (11.3cm) away
from the wing root. Drill a 5/64" (2mm) hole through the
fiberglass tube of the main wing halves, and make sure
they are firmly close to the fuselage then secure 3x15mm
wood screws.
61.Locate the retract servo link,E clip,short pushrod, M2 nut
and coupler and assemble it as shown on the photos . If
Futaba Retract servo is used,then the servo link is installed
on the second hole of the horn.
62.Fine adjust the retract pushrod, secure the pushrod and
servo link with 3x3 mm set screws. Try switching on the
retract gear to make sure the retract gear works fine. You
may glue a piece of plywood at the retract servo tray area as
there is space between the side frame and fuselage. This is
to ensure that servo tray is firmly secured without any
movement when it is working.
63.Place a battery in the battery case;use double side tape to
secure it in the front of battery case.You can use the excess
plywood to make a block to hold battery in place. It may
need an extension wire to connect to the switch harness.
Approximately 200~250g of weight will be added in the
front of the battery case. See balance section in page 20
and add proper weights to get right CG.
