Optional Flaps - GREAT PLANES Aviastar elite Instruction Manual

❏
11. Cut off the excess pushrod 1/4" [ 6.4 mm] beyond
the bends. Attach the pushrods to the servo arms using
nylon FasLinks.
❏
12. Thread the clevises up or down on the pushrods as
necessary to center the ailerons with the servo arms still
perpendicular to the servo cases. When satisfi ed, slide
the silicone clevis retainers to the ends of the clevises to
secure them.

13. If you plan to install the optional fl aps, proceed to the
next section. If not, skip the next section and set aside the wing
as it will not be needed again until the fi nal setup of the Avistar.

Optional Flaps

Installing fl aps will require a 5+ channel radio system and two
additional standard servos. The addition of fl aps will allow
the plane to fl y slower for takeoffs and landings. Note that
the fl aps are pinned in place during manufacturing and will
not be able to move until they are cut free at the end of this
assembly section.
❏
1. Locate the rectangular fl ap servo bays beneath the
covering. If you cannot see them, look at the wing at a shallow
angle or feel around the area shown in the picture and gently
push in on the covering to locate the corners of the bays. Use
a sharp hobby knife to trim the covering along the edges of
the bays.
❏
2. Temporarily connect each fl ap servo to the aileron
channel on your receiver and use the radio system to center
the servos. Install a four-armed servo arm onto each servo
perpendicular to the servo cases and cut away the other three
arms. NOTE: Unlike the aileron servos, the servo arms of the
fl ap servos must both point in the same direction. Enlarge the
outer most holes of each servo arm with a 5/64" [2mm] drill bit.
