2. Make the aileron pushrods from a

.074" x

threaded end rod with a nylon clevis

and

a solder clevis. We recommend silver solder

for the solder clevis. Drill 1/16" holes in the aileron

horn mounting plate and add a few drops of thin
CA to the holes and allow to harden. Mount a
control horn to the aileron with two #2 x 3/8"
screws and hook up the servo with the pushrod.

U 3. Thread another nylon clevis onto the end of

another

.074

x 4" threaded end rod. Bend and cut

the wire to the length shown on the wing plan for
the

right flap pushrod. Enlarge the holes in your

flap servo arms with a hobby knife (or a #48 drill for
perfection) and connect the flap pushrod to the
servo arm using a nylon

FasLink". Rotate the flap

servo arm to the

down position and set the flap

hatch cover (with the flap servo and pushrod
connected) over the flap hatch and guide the
pushrod out of the hole in the TE.

4. Temporarily connect the clevis to the flap

horn to see

the pushrod is approximately the

correct length.

5. Connect the other aileron and flap pushrod

the same way. Make final adjustments to the

lengths of the pushrods when you set up

your radio.

This is as far as we can

go with the wing until it is

fitted to the fuse. But first, we need a fuse,

so..

.build the

fuse!

BUILD

THE FUSELAGE

PREPARATION

Note: The die-cut 1/8" plywood formers are

stamped with only the necessaly portion of their

name. For example,

F-2B is stamped 2 8 . All

die-cut parts are 1/8" plywood unless they are
otherwise noted.

1. Position the bottom view of the fuselage plan

over your flat building board. Cover it with wax
paper. You may cut the bottom view from the rest
of the plan.

Use 30-minute epoxy to glue two die-cut 1/8"

plywood

F l B ' s together and F1T to the front of

F1DT (there are two F1DT's included in the kit but

only one is used). Clamp the assemblies

a flat

table or board or lay weights on them with wax

paper underneath. Inspect the parts closely before

the epoxy cures to make sure they remain aligned.
Wipe away excess epoxy before it cures. From

now on the F1B assembly will be referred to as

the

firewall.

3. Drill 1/16" holes through the punch marks in

F2D and F2 that are closest to the bottom of the

formers. Glue F2D to the front of F2 with the holes

aligned. After the glue dries, drill 5/16" holes
through the punch marks.

If you do not have a

5/16" drill bit you can start with a 1/4" hole and
enlarge it to approximately 5/16" with a hobby knife
or a round wood file. These holes do not have to be

exactly 5/16" or perfectly round.

If you're installing retracts, drill 1/8" holes

through the punch marks in the bottom of

F6 for the

air tank dowels and through the punch marks in F2

for the pull/pull nose steering cable guide tubes.

5. Drill 3/16" holes through the punch marks in

the die-cut 1/8" plywood formers

F6 through F l l .

When you drill the holes press down on each
former to prevent the wood from splitting when the
drill bit goes through.

If you plan to install the Top Flite Beechcraft

Bonanza Scale Interior Kit drill holes and cut slots
in the formers for routing the air lines and servo

wires between the fuse sides and the cockpit

interior in formers F3, F4 and F5.
