*Use the special Futaba charger.
• The charging time is 15 hours.
[However when the battery was
not used fo r some time , charge and
discharge it 2 — 3 times. Otherwise,
the battery will not be charged even
after t h e specified charging time !
A fully-charged transmitter battery
can be used for about 10 flights of
10 minutes each. The airborne NR4J Nicd battery pack can be used
for about 6 flights when 6 servos
are used.

and
• BEFORE USING
drain the battery pack very quickly. Make the
travel of each control mechanism somewhat
larger than the full stroke (including trim) of
the servo horn. Adjust the servo horns so that
they move smoothly even when the trim lever
and stick are operated simultaneously in the
same direction.
• Be alert for noise.
This set is noise-resistant, but not completely
immune to noise. The use of noiseless parts is
recommended.
•When installing the switch harness, cut a rectangular hole slightly larger than the full stroke
of the switch and install the switch so that it
moves smoothly from ON to OFF. Also do this
when the switch is installed inside the fuselage
and is turned on and off from the outside with
a piece of wire. Install the switch where it will
not be exposed to engine oil or dust and dirt.
• Although the antenna appears to be too long,
do not cut it or fold it back.
• Install the servos securely. Tighten the mounting screws until the rubber damper is crushed
slightly. If the screws are too tight, the cushioning effect will be adversely effected.
• The crystal can be changed from the outside of
the receiver case. Always use the Futaba transmitter/receiver matched crystal set to change
the band.
• The receiver that is used with the 7UAP and
7UAF is a dual conversion receiver. This receivers requires a special crystal so please order
the correct crystal set.
• Spare servo horns are supplied. Use them as
needed.
• Use extension cords matched to the model.
• Wrap the r eceiver in sponge rubber. Place it
inside a waterproof plastic bag and secure the
end of the bag with a rubber band. Do the
same with the airborne battery pack.
• Use th e rubber bands wrapped around the re-
ceiver to hold the servo and switch leads.
• After installation and checking are complete,
perform a range check by collapsing the transmitter antenna and extending the receiver
antenna to its full length and operating the
transmitter from a distance of 20 to 30 meters
from the receiver. The servos should operate
normally at this distance.
• Differs with the weather and surroundings.
