Top Flite TOPA0130 - Manual (Page 31)

excess before it dr ies. Avoid using CA
Accelerator as it will create lumps along the
seam that will cause problems when you try to
add the next piece of sheeting. Note: Do Not
glue the Fuse Sides to the top of the Stab
Saddle. The sides will ultimately attach to
the Vertical Fin Post. Repeat steps 4, 5, and 6
for the other side.
❏
7. Trim and sand the top edge of the Fuse
Sides flush with the top of the cockpit deck from
F-3 to F-6. Hint: To simplify the Upper Forward
Deck sheeting, trim away a sliver of Fuse Side
sheeting from the edge of the cockpit deck
forward, so that the Upper Deck sheet will only
need a straight cut to make it fit.
❏
8. Cut the Upper Forward Fuse Deck
template from the plans and glue it onto thin
cardstock (file folder). Use the template to cut
two Upper Forward Fuse Deck sheets from a
3/32" x 3-1/2" x 24" balsa sheet.
❏
9. Wet the outside of an Upper Fuse Deck
sheet and flex it with the grain to soften it up,
then place it on the upper forward frame.
It should overlap the Instrument Panel and F-1
by about 3/8". Align the sheet along the
centerline of the top Stringer, then temporarily
hold it in place with clothespins. Mark and cut
the lower edge to match the top edge of the
Fuse Side.
❏
10. Apply medium CA to all frame parts that
the sheet will contact except the top center
stringer. Roll the Deck sheet into position,
starting along the lower edge. Hold it in position
until the CA cures.
❏
11. Repeat steps 9 and 10 for the other side
of the fuse. After the Deck is sheeted on both
sides, wick thin CA down the top center Joint.
When the balsa is dry, lightly sand the joints
with #220 grit sandpaper. Sand the sheeting
flush with F-1.
INSTALL PUSHRODS
❏
1. Locate the 48" outer pushrod tube and
cut it into two lengths; one 22", and one 26".
Roughen the outside surface with #220 grit
sandpaper.
❏
2. Install the 22" elevator pushrod tube as
shown on the plans. Apply a drop of CA to the
tube at each Former.
❏
3. The Rudder pushrod exit is approximately
2-1/4" aft of F-8, and 1/4" above the Main
Stringer ledge. Cut a 3/16" x 1-1/2" slot at this
location for the 26" pushrod tube to exit. Bevel
the sheeting where it contacts the tube to avoid
bending the tube more than necessary. Install
the tube as shown in the photo to allow for
trimming later.
❏
4. Cut one .074" x 36" Pushrod Wire to
make an elevator pushrod 27-1/2" long. Cut six
1/8" long pieces of inner pushrod tube, then
slide these along the wire to the locations
shown on the plans.
❏
5. Silver Solder a Threaded Brass Coupler
to the unthreaded end of the pushrod.
❏
6. Screw a Nylon Clevis 20 revolutions
(5/16") onto the threaded end of the pushrod
wire. Locate the Elevator Joiner Wire. Snap
the Clevis into the middle hole and lock it in
place with the Silicone retainer. Slide the
Brass end of the pushrod through the pushrod
tube to the servo tray.
❏
7. Cut a notch in the aft edge of the Stab
Saddle as shown in the photo to provide
clearance for the Elevator Joiner Wire.
