Great Planes Ryan STA 1.20 ARF - GPMA1345 - Manual (Page 7)

Use care to cut just through the covering, while not cutting
into the wood. Glue the wing bolt plate into position. After the
glue hardens, use the holes in the top of the wing as a guide
to drill 17/64" (or 1/4") holes through the wing bolt plate.
Do the right aileron first.
❏ ❏
1. Drill a 3/32" hole 1/2" deep in the center of the
hinge slots in the right wing panel and right aileron. A drill
does the job okay, but a high-speed tool like a Dremel works
better. Insert a #11 knife blade into the slots, working it back
and forth a few times to clean them out.
❏ ❏
2. Cut the covering from the hinge slots.
❏ ❏
3. Cut four 3/4" x 1" hinges as shown in the sketch
from the supplied CA hinge strip.
❏ ❏
4. Test fit the aileron to the wing with the hinges. If the
hinge slots are too tight, remove the hinges and use a #11
blade to slightly open the slots. If necessary, insert a small
pin through the center of the hinges so they remain centered
when joining the aileron to the wing.
❏ ❏
5. With the aileron joined to the wing, remove any pins
used to center the hinges. Be certain there is a small gap
between the leading edge of the ailerons and the wing—just
enough to slip a piece of paper through or to see light through.
❏ ❏
6. Apply six drops of thin CA to both sides of all the
hinges. Allow a few seconds between drops to allow the
hinge slots to fully absorb the CA.
❏
7. Join the left aileron to the wing the same way.
Do the right aileron first.
❏
1. Cut the covering from the right aileron hatch in the
bottom of the wing.
❏
2. Connect a servo extension cord to your aileron servo
wire. Secure the connection with vinyl tape, heat shrink
tubing, or special clips intended for that purpose.
❏
3. Tie the end of the string that is taped inside the wing
to the end of the servo wire. Pull the wire through the ribs
and out of the hole in the middle of the wing.
