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.T o 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.

2. Use a fiber cutting tool to rough
cut the cowl and finish with a round
sander.Trial fit to make sure there is
a minimum of 3/8”around the engine
cooling.

31

YAK-54 73’’ have two that mount

from the rear of the firewall on the
top of the cowl and two that mount
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

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 Hi gh rate

12 Degrees on Low rate

Aileron: 30 Degrees on High rate

12 Degrees on Low rate

Rudder: 45 D egrees on Hi gh 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 up

34

35

■ 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 t he engine running and do a range

check w ith

■ 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 pi l ot 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 w hat you talked about during the flight or if you ger
into trouble . Alwa ys 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.

Flight Preperation

Pilot RC Control Horn Installation

(50cc and larger have dual control horns & 30cc Aircra have a single control horn)

• Rubber/Latex Gloves.

• Epoxy (30 Minute or Stronger)

• Epoxy Mixing Cups

• Epoxy Mixing Sticks (Any mixing stick that will t into the slot)

• Denatured Alcohol or Acetone.

• Paper Towels

• Sand Paper

• X-Acto Knife

• Dremel and Small Drill Bit (Optional and Not Always Needed)

en Prepare your parts..

en you will need to test t your parts together before gluing in place. Please note that
sometimes the slots need to be cleaned out a little bit and can be done with a dremel and a
small drill bit or an x-acto knife.

Force your epoxy into the slots. Also apply a thin layer of epoxy on the control horn and
bottom of the guide plate.

Install your horns. Make sure to clean o any epoxy that comes out from under the plate
with a paper towel and alcohol.

Pilot RC

Wing & Elevator Servo Installation

You will need:

• Hobby Iron

• X-Acto Knife

• in CA “Super Glue”

• Drill and Drill Bit

First nd the servo mounting hole and iron around to assure that the covering is stuck to
the surrounding wood.

en cut like this or to your preference.

en press and iron excess covering down into the servo slot.

Now you can pre t the servo.

Make sure your grommets are installed and drill the holes for the servo screws.

Now apply a small amount of the CA to the already drilled servo screw holes and if need­ed run your extension wire through. (Don’t forget the safety clip!!)

Now you can install the servo with your choice of screws and attach the linkage.

Final adjustment of turnbuckles and it ready for servo adjustment.
