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

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.
