3.4 Flying Tips 

This

 

aircraft

 

is

 

designed

 

to

 

be

 

the

 

perfect

 

“toss

 

in

 

the

 

car”

 

model

 

for

 

most

 

fliers!

  

The

 

compact

 

size

 

allows

 

it

 

to

 

fly

 

in

 

smaller

 

parks

 

and

 

indoor

 

flying

 

venues,

 

but

 

the

 

speed

 

that

 

it

 

is

 

capable

 

of

 

makes

 

it

 

a

 

great

 

choice

 

for

 

your

 

local

 

flying

 

field

 

as

 

well.

  

With

 

smaller

 

control

 

throws

 

and

 

more

 

expo,

 

the

 

4

Fitt

 

is

 

a

 

great

 

choice

 

for

 

newer

 

pilots

 

that

 

are

 

getting

 

their

 

feet

 

wet

 

with

 

aileron

 

controls.

  

Turn

 

the

 

throws

 

up

 

and

 

you

 

get

 

a

 

plane

 

that

 

is

 

extremely

 

aerobatic

 

and

 

will

 

perform

 

axial

 

rolls

 

at

 

an

 

alarming

 

rate!

  

Landing

 

the

 

aircraft

 

is

 

simple;

 

keep

 

some

 

throttle

 

applied

 

and

 

as

 

the

 

plane

 

nears

 

the

 

ground,

 

pull

 

back

 

on

 

the

 

elevator

 

to

 

flare.

 

We

 

developed

 

this

 

model

 

for

 

club

 

combat

 

events

 

and

 

have

 

found

 

many

 

pilots

 

bringing

 

them

 

out

 

on

 

non

combat

 

nights

 

because

 

they

 

are

 

just

 

so

 

much

 

fun

 

to

 

fly!

  

When

 

we

 

do

 

fly

 

combat

 

we

 

have

 

used

 

narrow

width

 

(~0.5”)

 

x

 

10’

 

crepe

 

paper

 

streamers

 

attached

 

with

 

tape

 

to

 

the

 

rear

 

of

 

the

 

fuselage

 

with

 

no

 

significant

 

degradation

 

in

 

performance.

  

In

 

the

 

“rare”

 

case

 

that

 

a

 

4

Fitt

 

is

 

involved

 

in

 

a

 

mid

air

 

collision,

 

the

 

interlocking

 

construction

 

should

 

provide

 

your

 

electronics

 

and

 

battery

 

protection

 

over

 

other

 

combat

 

plane

 

designs.

 

Remember:

 

Always

 

follow

 

the

 

AMA

 

safety

 

guidelines!

  

Never

 

fly

 

over

 

people

 

or

 

animals.

 

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

 

section

 

of

 

our

 

website)

 

for

 

decorating

 

as

 

it

 

is

 

easy

 

to

 

use,

 

lightweight,

 

and

 

provides

 

a

 

nice,

 

glossy

 

finish.

  

Water

based

 

paints

 

have

 

been

 

used

 

with

 

good

 

results

 

as

 

well.

  

Prior

 

to

 

using

 

any

 

paints

 

or

 

markers,

 

test

 

on

 

a

 

scrap

 

piece

 

of

 

foam

 

to

 

ensure

 

that

 

it

 

doesn’t

 

damage

 

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

 

design

 

and

 

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

 

available

 

for

 

purchase.
