3.4 Flying Tips 

This

 

aircraft

 

is

 

designed

 

to

 

fly

 

in

 

the

 

space

 

as

 

small

 

as

 

a

 

single

 

basketball

 

court.

  

Being

 

such

 

light

 

weight,

 

it

 

is

 

recommended

 

that

 

this

 

aircraft

 

be

 

flown

 

indoors

 

or

 

outdoors

 

in

 

calm

 

wind

 

conditions.

  

Always

 

ensure

 

that

 

you

 

are

 

comfortable

 

with

 

the

 

aircraft

 

and

 

its

 

flight

 

characteristics

 

prior

 

to

 

flying

 

in

 

a

 

small

 

venue.

  

If

 

you

 

want

 

to

 

fly

 

slower,

 

choose

 

the

 

rudder/elevator

 

version.

  

If

 

you'd

 

like

 

to

 

fly

 

more

 

aerobatically,

 

pick

 

the

 

elevons.

  

Never

 

fly

 

over

 

people

 

or

 

animals.

 

This

 

aircraft

 

flies

 

much

 

“bigger”

 

than

 

it

 

really

 

is

 

and

 

the

 

techniques

 

of

 

flying

 

larger

 

aircraft

 

apply.

  

Rudder

 

turns

 

will

 

bank

 

the

 

aircraft

 

so

 

elevator

 

will

 

need

 

to

 

be

 

added

 

to

 

maintain

 

altitude.

  

The

 

delta

wing

 

design

 

is

 

inherently

 

stable

 

and

 

makes

 

this

 

model

 

a

 

pure

 

joy

 

to

 

fly!

  

This

 

model

 

can

 

fly

 

slowly

 

in

 

high

 

alpha

 

flight,

 

but

 

when

 

you

 

drop

 

the

 

nose

 

it

 

is

 

remarkably

 

quick

 

and

 

nimble.

  

Landing

 

the

 

aircraft

 

is

 

simple;

 

keep

 

some

 

throttle

 

applied

 

and

 

as

 

the

 

plane

 

nears

 

the

 

ground,

 

pull

 

back

 

on

 

the

 

elevator

 

to

 

flare.

 

3.5 Decorating/Finishing 

The

 

beauty

 

of

 

this

 

aircraft

 

is

 

that

 

you

 

have

 

the

 

opportunity

 

to

 

finish

 

it

 

with

 

the

 

look

 

that

 

you

 

desire.

  

We

 

recommend

 

using

 

colored

 

packaging

 

tape

 

(available

 

on

 

the

 

Building

 

Supplies

 

tab)

 

for

 

decorating

 

as

 

it

 

is

 

easy

 

to

 

use,

 

lightweight,

 

and

 

provides

 

a

 

nice,

 

glossy

 

finish.

  

Water

based

 

paints

 

have

 

been

 

used

 

with

 

success

 

in

 

the

 

past

 

as

 

have

 

permanent

 

markers.

  

Prior

 

to

 

using

 

any

 

paints

 

or

 

markers,

 

test

 

on

 

a

 

scrap

 

piece

 

of

 

foam

 

to

 

ensure

 

that

 

it

 

doesn’t

 

melt

 

the

 

foam.

   

Remember

 

that

 

any

 

weight

 

you

 

add

 

to

 

the

 

airframe

 

will

 

affect

 

its

 

performance

 

so

 

keep

 

heavy

 

applications

 

of

 

paint

 

and

 

decals

 

to

 

a

 

minimum.

 

3.6 Repairs & Spare Parts 

Due

 

to

 

this

 

models

 

extremely

 

light

 

weight,

 

it

 

is

 

surprisingly

 

durable!

  

If

 

a

 

part

 

of

 

the

 

model

 

is

 

damaged

 

it

 

can

 

typically

 

be

 

repaired

 

using

 

small

 

pieces

 

of

 

packaging

 

tape

 

or

 

by

 

gluing

 

using

 

Beacon

 

Foam

 

Tac

.

   

If

 

a

 

part

 

is

 

damaged

 

beyond

 

repair,

 

simply

 

send

 

us

 

an

 

email

 

at

 

Support@Sawn

Craft.com

 

as

 

we

 

have

 

replacement

 

parts

 

for

 

purchase.
