Top Flite TOPA0305 Part 2 - Manual (Page 13)

HOOK UP THE RUDDER AND
ELEVATO R
Note: As on the full size Beechcraft, the elevators
and rudder can touch,
but the rudder throw will be
set so that this does not happen during flight.
ST1. Install the pushrods in the guide tubes.
Temporarily connect the clevises to the rudder
control horn and fit the rudder and elevator
in
place.
ST2. Place a servo arm on your rudder and
elevator servos. With the servos centered and the
rudder and elevators neutral, use a felt-tip pen to
mark the pushrods exactly 1 -1/4" from the holes in
the servo arms. Remove the pushrods from the
fuselage. Cut them at the marks you made.
ST3. Silver solder a threaded coupler onto
each wire pushrod. Reinsert the pushrods into the
fuselage and thread a nylon clevis onto the
couplers. Temporarily connect the pushrods to the
servos and rudder and elevator. Adjust the length
of the pushrods if necessary by turning the clevises
in or out.
BUILD THE DORSAL FIN
ST1. Use the pattern on the plan to make the
dorsal fin base from leftover 1/16" balsa. Glue the
dorsal fin base to the top of the turtle deck. Make
sure the front of the base is centered on the fuse
centerline.
1/16"
1/2"
. . .
ST2. Cut the 15" tapered balsa dorsal tin LE to
the shape shown on the plan. Glue the dorsal fin
LE to the fin LE and the dorsal fin brace.
ST3. Make two dorsal fin sheets from leftover
1/16" balsa sheeting and pattern on the plan. Test
fit and glue one of the sheets to the turtle deck and
dorsal fin base. Wet the sheet and glue it to the
dorsal fin LE. Make sure you do not pull the dorsal
fin LE
off to one side when you glue the sheet to it.
Glue the other dorsal fin sheet in position.
- 4 9 -
ST4. Glue the 1/16" die-cut plywood fin filler to
the dorsal fin and fin.
ST5. Apply Hobbylite filler to the dorsal fin and
fin filler to blend them to the fin. Apply filler to the
front of the dorsal fin to complete the taper and
blend it to the turtle deck. Do not apply all the filler
in one application but build up thin layers, allowing
each layer to fully dry before you apply the next.
,
ST6. Sand the fillet, blending the dorsal fin, fin
filler and fin into one smooth contour.
