INTRODUCTION

Thank you for purchasing

our new 50cc Yak-54. we strive

to achieve the real Quick

Builded and ARF aircraf .

It just requires the least

amout of assembly of any kit

that almost finished in

factory.To obtain the perfect

performence,both the design

and manufacturing have been

taken care with the highest

quality from any

hardware,covering ,wood and

glue in the construction as

well.By optimal weight and

reliable construction,you will

find this plane is really ideal

for 3D -Freestyle and

aerobatic.

So we hope every effort and

service we offer will make you
feel easy and have a wonderful
time in the pleasure of flying in

3D space.

from the front of the cowl opening

4. Ensue all the corner are rounded
and not sharp 90 degrees against
splitting under vibration. Trial fit till
the cowl is right

Maybe more exit air cooling
will be needed to allow for
depending on your engine’s
recommended running
temperature.Always check
your engine and Pilot-rc
dosen’t accept responsibility
for any damage from
improper engine cooling

NOTICE:

YAK-54 73’’ need an extension tool

with a proper size ball driver and
handle by cutting standard ball driver
in half .Some small heat shrink
tubing are attached to the ball driver
to hold in place.You have to reattach
the cowl in the future by this method

CG And Control Throws

■ Afer you set the given control

throws up and have a few flights under
you belt, you can change the amounts
as well as moving the CG back at 1/4"
intervals

Elevator: 40 Degrees on High rate

12 Degrees on Low rate

Aileron: 30 Degrees on High rate

12 Degrees on Low rate

Rudder: 45 Degrees on High rate

40 Degrees on Low rate

Throttle: Adjust idle –full

■ Learn to use exponential of about

40 percent on your elevator to make
great landings and not over control a
highly aerobatic airplane.Use 70
percent exponential on High Rate!

The First Flight set upCenter Of Gravity

The center of gravity is on the
rear of the wing tube as shown

Your balance at the CG will
determine batteries final mounting
location .Mount batteries and
secure with Nylon ties

■ Make sure you have the right model programmed into your

transmitter

■ Check the direction of each surface not and also right before

you take off .

■ Rememver nothing wrong on the ground ever improves in

the air

■ Check the air plane with the engine running and do a range

check with

■ your body between you and the plane at 150 feet.

■ Check your battery voltage after each flight in case one

servo is draining your battery

■ Recheck all screws ,horns and linkages for slop after your

maiden fight and check for damage if you made a bad landing
you first time

■ Have an experienced pilot fly it for you the first time if you

have any doubts in your mind about the maiden flight

■ Take a break after you first flight and let the adrenaline

burned off by bragging to your fellow menbers how good it
flies

■ Fly low and at a medium speed on your first few flight

■ Listen to your engine run and have an observer with you to

remember what you talked about during the flight or if you ger
into trouble . Always balance your props, vibration is a killer.

■ Remember nose heavy airplanes fly all the time, tail heavy

airplanes fly only once.Be on the CG!

■ Fly 3D two mistakes high in the beginning and not close to

people, planes or runways. Being a center of the runway hog
does not endear you to many modelers.
