Warning!
Basically, this model aircraft is meant to be flown by experienced fliers. First-time fliers should seek advice for hints in pre-flight
adjustments and assembly from experienced fliers. Be reminded that flying a badly assembled or badly adjusted aircraft is very
dangerous!
In the beginning, first-time fliers should always be assisted by an experienced flier and never fly alone!
This model aircraft is designed to be powered by a 2-stroke .40 ~ .46 engine or a 4-stroke .48 ~ .53 engine. Installing a more
powerful engine than specified or flying the PIPER J-3 CUB aggressively may lead to serious damages and accidents!

Before Flying
Before flying your airplane, ensure
the airfield is spacious enough.
Always fly it outdoors in safe areas
with no debris or obstacles!
For handling the radio properly,
refer to its instruction manual.
Ensure the spinner and propeller are
securely attached.
If your airplane begins to operate by
itself, there is another transmitter on
your frequency. Immediately stop
your airplane; otherwise you may
lose control of it which will result in
accidents.
Fully extend
the transmitter
antenna.
Switch on the transmitter.
Switch on the receiver.
Ensure the wings are securely
attached.
Flying
Fill the fuel tank.
By moving the control sticks, ensure
all control surfaces moves as per
your adjustments.
For starting the engine, apply low
throttle and hold the engine starter
against the spinner.
Adjust the needle.
After Flying
Only use KYOSHO genuine parts!
Cautions for Safety
Adjust the engine always from behind,
but never from infront or the sides as
a rotating propeller may badly injure
you!
Do not allow watching people to get
too close to a rotating propeller.
Immediately disuse defective pro-
pellers as well as deformed spinners.
If the dry batteries in the radio are
flat, replace them with fresh ones.
Do not fly your airplane above people
standing around.

lowering the throttle trim.
After each flight, the engine is very
hot. Beware of getting burned!
Wipe away any fuel deposits or dirt.
