Great Planes Avistar Elite .46 RTF - GPMA1605 - Manual (Page 10)

Optional Flaps
Installing fl aps will require 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.
❏
3. Install the rubber grommets and eyelets on the servos.
Route the servo leads through the wing ribs and out the root
ribs (the distance through the wing for the fl ap servo leads is
shorter than the ailerons so using string to pull them through
is not necessary). Fit the servos in place and drill the servo
mounting holes using a 1/16" [1.6mm] drill bit. Apply a drop of
thin CA to each hole. Then install the servos using the screws
provided in the servo hardware bag. The servo arm of the left
fl ap servo should point to the wing tip and the servo arm of
the right fl ap servo should point to the wing root.
❏
4. Now connect each fl ap servo to the fl ap channel on
your radio and use the fl ap dial on your transmitter to rotate
the servo arms toward the fl aps as far as the radio will allow.
