Mounting

 

the

 

Elevator

 

Servo

 

&

 

Linkage

 

1.

 

You

 

can

 

use

 

the

 

servo

 

mount

 

provided

 

in

 

the

 

fuselage

 

to

 

mount

 

your

 

elevator

 

servo.

  

However

 

this

 

will

 

introduce

 

a

 

slight

 

differential

 

between

 

up

elevator

 

and

 

down

elevator

 

because

 

of

 

the

 

geometry

 

difference

 

between

 

the

 

elevator

 

control

 

arm

 

moving

 

in

 

a

 

horizontal

 

plane

 

and

 

the

 

elevators

 

moving

 

in

 

a

 

vertical

 

plane.

 

2.

 

A

 

better

 

solution

 

is

 

to

 

build

 

an

 

elevator

 

servo

 

mounting

 

plate

 

that

 

allows

 

the

 

elevator

 

servo

 

to

 

be

 

mounted

 

on

 

its

 

side

 

therefore

 

allowing

 

the

 

elevator

 

control

 

arm

 

to

 

be

 

in

 

the

 

same

 

plane

 

as

 

the

 

elevators.

 

3.

 

Whichever

 

solution

 

you

 

select,

 

align

 

the

 

servo

 

so

 

that

 

the

 

servo

 

arm

 

is

 

exactly

 

centered

 

in

 

the

 

fuselage.

 

4.

 

The

 

push

pull

 

control

 

rod

 

system

 

used

 

in

 

the

 

Aquila

 

is

 

used

 

in

 

a

 

great

 

many

 

pattern

 

plane

 

installations

 

and

 

should

 

be

 

familiar

 

to

 

many

 

modelers.

  

Feel

 

free

 

to

 

substitute

 

your

 

own

 

instructions

 

here

 

if

 

you

 

feel

 

they

 

are

 

better

 

suited

 

to

 

your

 

needs.

 

5.

 

Looking

 

at

 

the

 

long

 

CF

 

rod

 

you

 

will

 

notice

 

that

 

the

 

manufacturer

 

anticipated

 

your

 

needs

 

and

 

pre

drilled

 

holes

 

in

 

both

 

ends

 

for

 

the

 

wire

 

pushrods

 

to

 

attach.

  

Unfortunately

 

the

 

holes

 

that

 

are

 

pre

drilled

 

for

 

you

 

are

 

not

 

in

 

the

 

correct

 

place.

  

Please

 

use

 

thick

 

CA

 

to

 

close

 

the

 

pre

drilled

 

holes.

 

6.

 

Turn

 

the

 

fuselage

 

upside

 

down

 

and

 

look

 

to

 

the

 

tail

 

of

 

the

 

airplane.

  

There

 

you

 

will

 

find

 

a

 

removable

 

hatch.

  

Please

 

remove

 

this

 

hatch

 

for

 

now.

  

This

 

hatch

 

allows

 

you

 

to

 

see

 

where

 

the

 

elevator

 

push

rods

 

will

 

exit

 

the

 

fuselage

 

and

 

allows

 

you

 

to

 

see

 

a

 

wooden

 

bearing

 

(plate

 

with

 

a

 

hole

 

in

 

it)

 

that

 

will

 

support

 

the

 

CF

 

elevator

 

pushrod.
