swage to secure the cable. Fit the threaded rod into

one of the Screw-Lock connectors and temporarily
lock it down with a

4-40

x 118" socket head screw.

Connect another piece of cable to the other
Screw-Lock connector the same way, then thread
the cable through the guide tubes toward the nose
gear strut.

R2.

Install a 0-80 threaded ball link ball (not

included) onto the arm on both sides of the nose

wheel strut with a 0-80 nut. Connect the other end

of both cables to the threaded ball links with the
swages. Tighten the loop in the cable just enough

so

it

will not come

off the ball. Crimp the swages.

Temporarily hook up the steering servo to your

radio system and test the movement. Adjust the

tension on the cables or make other adjustments if

needed.

Note: If your nose gear steering arms did not come
bent 90" as shown, do

so

now.

HOOK UP THE THROTTLE

1. Mount your engine mount and engine to the

firewall. Mount your muffler to make sure your

throttle pushrod will not interfere.

This is the throttle servo location for fixed gear,

This is the throttle servo location for retractable gear.

2.

Place your throttle servo tray with the servo in

the rails. Connect the

,074"

x 12" throttle pushrod

to your servo with a small, brass Screw-Lock
connector.
Connect the other end of the throttle

pushrod to the engine with a nylon ball socket and
a 0-80 threaded ball and 0-80 nut. Use a drop of

thread lock on the nut. Glue the throttle servo tray
to the rails.

MOUNT THE WING TO THE FUSE

Remember the wing?

Go

get it

so

you

can mount it

to

the fuse.

Bevel the end of both

1/2"

x 1" x

2-1/4"

maple

wing bolt blocks

so they match the angle of the

die-cut 1/8" plywood wing bolt block holder.

2. Use 30-minute epoxy to glue the wing bolt

blocks and holders in the fuse where shown on the
plan. See the photo at step 8.

3. Place the wing in the wing saddle on the fuse.

Observe high spots in the saddle of the balsa fuse
sides that prevent the wing from fitting. Remove the
wing and sand the high spots

so the wing matches

the fuse as accurately as possible.

Do

not sand the

ply fuse side doublers.

4.

Remember the pin and

string method you

used to align the stab? Get your string out and stick
a T-pin in the center of the bottom, middle stringer

just ahead of the tail cone.

5.

Use the arrow on the tape to align the wing

with the fuse the same way you did the stab.

6.

Once you have the wing aligned, place

weights over the center section to keep it from

shifting during the next few steps. Keep your string
handy

so you can recheck alignment as

you proceed.
