Reinstall

the

CF

pushrod

with

the

two

wire

pushrod

assembly

into

the

fuselage

and

into

the

bearing

in

the

aft

of

the

fuselage.

Connect

the

wire

pushrod

ends

to

the

elevator

control

horns

and

set

the

elevators

to

neutral.

Temporarily

tape

the

elevator

halves

in

this

position.

15.

Locate

the

laser

‐

cut

1/16”

plywood

elevator

pushrod

bearing

doubler.

The

piece

gets

added

to

the

end

of

the

CF

pushrod

from

behind

the

bulkhead

with

the

bearing

in

it.

The

bearing

that

is

in

the

bulkhead

has

a

loose

fit.

This

1/16”

plywood

bearing

has

a

slightly

snug

fit

and

will

keep

the

CF

rod

from

moving

around.

Trial

fit

this

bearing

a

couple

of

times

before

attempting

to

glue

it

in

place.

Once

you

are

satisfied

that

you

can

correctly

install

this

part,

add

a

couple

of

drops

of

thick

CA

to

the

front

face

of

the

1/16”

plywood

part

and

slip

it

onto

the

back

of

the

CF

rod

and

press

it

into

place

on

the

back

of

the

bulkhead.

You

need

enough

glue

to

hold

the

part

in

place

but

too

much

glue

might

glue

your

CF

elevator

pushrod

to

the

bearing

.

16.

Release

the

tape,

or

pins,

holding

the

elevator

and

manually

move

the

elevators

through

the

full

range

of

motion

needed

(both

up

and

down)

and

ensure

nothing

is

binding

and

that

you

have

free

movement.

Adjust

the

setup

as

needed.

17.

With

your

elevator

servo

installed,

connect

the

wire

pushrod

to

the

elevator

servo

control

arm.

18.

Set

the

elevator

halves

to

neutral

and

tape,

or

pin,

them

in

this

position.

Also

set

the

elevator

servo

at

neutral.

19.

You

should

see

that

the

wire

pushrod

connected

to

the

elevator

control

arm

overlaps

the

CF

pushrod.

Use

thick

CA

and

kicker

to

glue

the

wire

pushrod

to

the

CF

pushrod.

20.

Once

the

CA

has

set,

use

strong

nylon

thread,

or

Kevlar

thread,

to

wrap

the

joint

completely,

and

then

apply

thin

CA

to

the

thread.

Heat

shrink

tubing

provided

can

be

used

over

the

CA

joints

to

further

strengthen

the

wire

to

CF

joint.

21.

Just

aft

of

the

cockpit

inside

the

fuselage

use

scrap

wood

to

build

a

support

for

the

elevator

CF

pushrod.

22.

Remember

to

free

your

elevator

halves

and

test

for

full

motion.

23.

Adjust

as

needed.
