This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your PIPER CUB-EP. Use the parts listing below
to identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it
is capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C
supplierandjoinyourlocalR/CModelFlyingClub.R/CModelFlyingClubsofferavarietyoftraining

To avoid scratching your new airplane, do
not unwrap the pieces until they are needed
for assembly. Cover your workbench with an
old towel or brown paper, both to protect the
aircraftandto protect the table. Keepacouple
of jars or bowls handy to hold the small parts
after you open the bag.
Please trial fit all the parts. Make sure you
havethe correct parts andthat they fitandare
alignedproperlybeforegluing!Thiswillassure
proper assembly. PIPER CUB-EP ARF is hand
made from natural materials, every plane is
unique and minor adjustments may have to
be made. However, you should find the fit
superior and assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

 3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .

1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
65MMBACK FROMTHELEADINGEDGEOF
THEWING.

2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing 65 mm back from
the leading edge, at the fuselage sides.
BALANCING.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 65mm back from the
leadingedge. Thisisthebalancepoint atwhich
yourmodelshouldbalanceforyourfirstflights.
Later, you may wish to experiment by shifting
the balance up to 10mm forward or back to
change the flying characteristics. Moving the
balance forward may improve the smooth-
ness and arrow- like tracking, but it may then
require more speed for take off and make it
moredifficulttoslow down for landing.Moving
the balance aft makes the model more agile
with a lighter and snappier ”feel”. In any case,
please start at the location we recommend .
With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.
Lift the model. If the tail drops when you
lift,the modelis “tail heavy” and you must add
weigh*tothe nose. Ifthenosedrops,itis“nose
heavy” and you must add weight* to the tail to
balance.
*Ifpossible, first attemptto balance themodel
by changing the position of the receiver bat-
tery and receiver. If you are unable to obtain
good balance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.
