BUILDING

 

THE

 

MODEL

 

BEFORE

 

STARTING

 

A

 

note

 

about

 

the

 

photos:

  

The

 

photos

 

were

 

taken

 

of

 

a

 

prototype

 

and

 

the

 

parts

 

supplied

 

may

 

look

 

slightly

 

different

 

from

 

them.

  

However,

 

the

 

concepts

 

illustrated

 

are

 

the

 

same.

  

WINGS

 

Wing

 

Construction

 

Pin

 

down,

 

over

 

the

 

plan,

 

the

 

t/e,

 

spars

 

and

 

wing

 

tip,

 

gluing

 

as

 

required.

  

Add

 

the

 

leading

 

edge

 

stock

 

after

 

the

 

basic

 

frame

 

is

 

done

 

as

 

the

 

stock

 

is

 

inserted

 

in

 

a

 

rotated

 

fashion.

  

Add

 

the

 

wing

 

tips

 

and

 

align

 

the

 

front

 

tip

 

along

 

the

 

center

 

of

 

the

 

leading

 

edge.

  

Sand

 

the

 

leading

 

edge

 

stock

 

to

 

be

 

rounded

 

and

 

meet

 

the

 

ribs.

 

 
 

 

Wing

 

Pinned

 

to

 

Plan

 

 

Scalloping

 

can

 

be

 

done

 

easily

 

by

 

fitting

 

sandpaper

 

on

 

a

 

dowel

 

or

 

other

 

appropriately

 

shaped

 

object

 

and

 

simply

 

sand

 

the

 

scallops.

  

Start

 

sanding

 

at

 

the

 

center

 

point

 

of

 

the

 

scallop

 

and

 

stop

 

as

 

soon

 

as

 

the

 

desired

 

depth

 

is

 

reached.

 

 

Wing

 

Detail

 

(Note:

 

Photo

 

is

 

of

 

the

 

Albatros

 

DIII

 

Aileron)

 

 

The

 

leading

 

edge

 

of

 

the

 

aileron

 

is

 

rounded

 

over

 

with

 

sandpaper

 

to

 

make

 

the

 

aileron

 

movable

 

with

 

a

 

minimum

 

gap.

  

The

 

trailing

 

edge

 

of

 

the

 

wing

 

in

 

that

 

section

 

is

 

left

 

flat.

 

 

FUSELAGE

 

CONSTRUCTION

 

The

 

fuselage

 

is

 

built

 

as

 

two

 

side

 

structures,

 

which

 

are

 

then

 

joined

 

over

 

the

 

plan.

  

This

 

system

 

not

 

only

 

keeps

 

each

 

stage

 

simple,

 

but

 

it

 

also

 

helps

 

to

 

ensure

 

a

 

straight

 

fuselage.
