Top Flite TOPA0101 - Manual (Page 29)

❏
9. Look at the photo and the plan. Make FWD
and AFT wedges from 3/16" or 1/8" leftover balsa.
Note the clearance holes in the aft wedge for the
elevator torque rods.
❏
10. Glue the wedges in place. Use masking tape
to protect the stab while you sand the tops of the
wedges flush. Fit the 1/2" x 1" x 7-1/2"
upper aft
fuse block . Glue it in place. Rough shape the sides
of the block to a taper but do not round the corners
until after the rudder fillet block is installed.
❏
11. Move the rudder torque rod through its
range of motion. Make sure it is at an elevation
where it is not binding or striking a former. Mark
the height on the rudder where the torque wire
bends aft. Drill a 3/32" hole in the rudder to engage
the wire. Slot the lower leading edge of the rudder
to accept the remainder of the torque rod.
❏
12. Refer to the plan to obtain a starting point
for shaping the 3/4" x 1" x 6" rudder fillet block .
Shape the rudder fillet block by trial fitting it
between the rudder and the fuse. Mark the radius
on the side of the fillet block by extending a line off
the bottom of the rudder. When the shape is close,
glue the fillet block in place on the fuselage. Use
the photos to assist you in obtaining the final
shape of the fillets.
❏
13. Sand the end of the fuselage flat and glue
the shaped balsa aft tip block to the end of the
fuselage. Sand it to shape.
❏
14. Mark the elevators left and right. Mark the
location of the torque rods on the elevators. Drill
the elevators with a 1/8" bit to accept the torque
rod. Notch the LE of the elevator to accept the
torque rod.
