With

 

GPS

 

locked

 

(more

 

than

 

5

 

satellites

 

locked)

 

and

 

Motor

 

arming

 

done,

 

the

 

craft

 

will

 

record

 

its

 

home

 

position.

 

   

a)

 

Push

 

CH6

 

to

 

position

 

2

 

to

 

enter

 

RTL

 

(return

 

and

 

land)

 

mode.

 

In

 

the

 

Return

 

and

 

Land

 

mode,

 

the

 

craft

 

will

 

return

 

home

 

and

 

land

 

automatically.

   

b)

 

After

 

activation,

 

you

 

can

 

only

 

change

 

to

 

Stabilization

 

Mode

 

if

 

you

 

want

 

to

 

take

 

over

 

the

 

flight

 

controls.

 

If

 

you

 

move

 

from

 

RTL

 

to

 

Auto

 

Hover

 

Mode,

 

the

 

aircraft

 

will

 

continue

 

with

 

the

 

Return

Land

 

process.

   

c)

 

On

 

arrival

 

at

 

‘Home’,

 

the

 

YS

S4

 

V2

 

will

 

begin

 

to

 

descend.

 

At

 

this

 

time,

 

the

 

autopilot

 

will

 

allow

 

you

 

to

 

take

 

over

 

AIL

 

and

 

RUD

 

controls

 

to

 

adjust

 

the

 

landing

 

site,

 

but

 

the

 

THR

 

cannot

 

be

 

controlled.

 

The

 

THR

 

control

 

is

 

fully

 

autonomous

 

for

 

descent

 

and

 

landing.

 

 

d)

 

Altitude:

 

If

 

the

 

craft

 

is

 

beyond

 

25

 

meters

 

away

 

from

 

home

 

position

 

and

 

below

 

20

 

meters

 

altitude,

 

the

 

YS

S4

 

V2

 

will

 

ascend

 

to

 

20

 

meters

 

before

 

initiating

 

RTH

 

when

 

it

 

enters

 

RTL

 

mode.

 

If

 

its

 

height

 

is

 

more

 

than

 

20

 

meters,

 

the

 

YS

S4

 

V2

 

will

 

maintain

 

altitude

 

during

 

RTH.

 

If

 

the

 

distance

 

from

 

home

 

position

 

is

 

more

 

than

 

20

 

meters,
