Thank you for purchasing our new 

30cc aerobatic plane. we strive to 

achieve a good quality quick build 

ARF aircraft .

It requires the least amount of 

assembly of any ARF kit to obtain 

the maximum performance.

Both the design and manufacturing 

have been undertaken to the 

highest standards, using best 

quality hardware, covering, wood & 

glue during factory construction 

stage.

By optimal weight and balance 

along with reliable construction, 

you will find this plane ideal for 3D -

Freestyle and aerobatic flying.

We hope that every effort and 

service we offer will, in turn, give 

you confidence using PILOT

of the exit air cooling. But do not cut 

off the crowl mounting holes position 

as shown

3. Also cut out for clearance for the 

exhaust pipes

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

34

■ After you have set the given control 

throws and have a few flights under 

your belt, you can change the throws 

as well as moving the CG back at 1/4" 

intervals to suit your requirements and 

skill level.

■ Learn to use exponential of about 

40 percent on your elevator to make 

smooth landings and prevent over 

control on this highly aerobatic 

airplane. Use 70 percent exponential 

on High Rate!
35

Flight Preperation

■ Make sure you have the right model programmed into your 

transmitter

■ Check the direction of each control surface for correct 

operation before you take off .

■ Remember nothing wrong on the ground ever improves in 

the air

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

check with as per your radio manufactures instructions your 

body should be 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 

your first time

■ Have an experienced pilot fly it for 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 burn 

off by bragging to your fellow members how good it flies

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

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

remember what you talked about during the flight or if you get 

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 sure about the CG!

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

people, planes or runways. Being a center of the runway hog 

does not endear you to other modelers.
