This aircraft is for intermediate to advanced builders and flyers only. Biginners connot fly and building this aircraft.
This aircraft has been flight tested with snap-rolls and other aerobatic maneuvers. However,repeated violent maneuvers
may overstress the airframe. Please fly in a way that will not otherstress the airframe.
Repeated flying can cause stress cracks to appear in the wood and joints, please inspect after each flight. If any
abnormalities are noted, repair immediately before the next flight to avoid accidents.
Glue joints can loosen even though they appear to be tight. If you notice irregular flight, investigate the cause and repair it
before the next flight.
Even though the kit's supplied with fitted linkages, improperly assembling then can result in binding or loose control
surfaces. This can cause flutter and aircraft control problems. Make sure all linkages are tight and control surfases move
properly before flying.
This aircraft is designed to be powered by either a 2 stroke .40-.46 or a 4 stroke .52-.53 sized engine. Installation of
engines other than those specified could to lead to a serious accident and/or damage to property.
Do not overlook this symbol!

Before Flying
Before enjoying flying your air-
plane, sufficiently make sure the
airfield is spacious. Always fly it
outside rooms in safe areas with
no debris or obstacles!
For radio equipment, refer to the
manual included with the radio.
Check that the spinner and the
propeller are securely fastened.
If the model begins to operate by
itself, there is another transmitter
on your frequency. Do not try to
operate your model under such
condition for it may go out of
control.
Fully extend
transmitter
antenna.
Switch on the transmitter.
Switch on the receiver.
Check that the wings are properly
and firmly affixed.
Flying
Fill in the fuel.
By moving the controls (trans-
mitter), check that all rudders
move the way you adjusted them.
For starting the engine, apply low throt-
tle and hold the engine starter against
the spinner.
Adjust the needle.
After Flying
Only use KYOSHO genuine parts.
Cautions for Safety
Always regulate the engine from behind,
but never from infront or from the sides,
because a rotating propeller might badly
injure you.
Do not allow watching people to get too
close to a rotating propeller.
Immediately disuse defective propellers
as well as deformed spinners.
If the batteries of the radio system
are flat, replace them with new ones.
Do not fly your airplane above people
standing around.

Hand-launch your airplane into the wind
and make it take off.
Do not fly your airplane when
there is a strong wind or side
wind.
Always land your airplane into the
wind.
Bring your airplane to a halt by
lowering the engine control trim.
After each flight, the engine is hot. Be-
ware of getting burned.
Wipe up any fuel deposits or dirt.
Never throw burning, gleaming or smoul-
dering things into fuel cans, even if
these happen to be empty. This could
result in serious injury.
