FLYING

 

Let

 

the

 

model

 

gain

 

altitude

 

slowly

 

off

 

the

 

runway.

 

Applying

 

too

 

much

 

up

 

elevator

 

at

 

slow

 

speeds

 

risks

 

a

 

stall.

  

Make

 

your

 

turns

 

gently

 

as

 

tight

 

turns

 

risk

 

tip

 

stalling

 

in

 

any

 

model.

 

Don’t

 

expect

 

the

 

elevator

 

to

 

make

 

the

 

model

 

climb.

 

Think

 

of

 

the

 

elevator

 

as

 

a

 

device

 

to

 

change

 

the

 

attitude

 

of

 

the

 

model.

 

The

 

wing

 

and

 

airspeed

 

ultimately

 

make

 

the

 

model

 

climb.

 

Often

 

down

 

elevator

 

applied

 

at

 

stalling

 

can

 

avoid

 

a

 

major

 

crash.

 

The

 

most

 

important

 

details

 

for

 

proper

 

flight

 

operations

 

are:

 

1)

 

CG

 

location.

 

Tail

heavy

 

models

 

never

 

fly

 

well

 

or

 

at

 

all.

  

2)

 

Down

 

and

 

right

 

thrust

 

3)

 

Straight

 

and

 

non

warped

 

wings.

  

Here

 

are

 

some

 

excerpts

 

of

 

Brian’s

 

maiden

 

flight

 

report.

 

“We

 

got

 

to

 

the

 

field

 

and

 

while

 

the

 

Pfalz

 

was

 

charging

 

we

 

flew

 

other

 

planes

 

and

 

had

 

a

 

great

 

time.

 

I

 

set

 

her

 

on

 

the

 

runway

 

and

 

powered

 

her

 

up.

  

She

 

was

 

off

 

the

 

ground

 

is

 

less

 

than

 

25

 

ft

 

with

 

minimal

 

rudder

 

and

 

climbed

 

out

 

nicely.

 

I

 

flew

 

her

 

for

 

about

 

7

 

minutes

 

with

 

several

 

landings

 

and

 

takeoffs

 

for

 

trim

 

adjustments

 

etc.

 

had

 

three

 

takeoffs

 

and

 

landings.

 

She

 

looks

 

absolutely

 

stunning

 

in

 

the

 

air.

 

I

 

had

 

to

 

turn

 

the

 

elevator

 

rates

 

up

 

as

 

I

 

ran

 

out

 

of

 

elevator

 

on

 

a

 

couple

 

of

 

the

 

landings,

 

when

 

turned

 

up

 

the

 

landings

 

were

 

fine.
