BATTERY PACK
"ON" FOR CHARGING
CHARGING INSTRUCTIONS:
Your transmitter contains a built-in transformer type nickel cadmium
battery charger. A dual charging cord is packed with your radio control system. If you will examine, the charging cord, you will note that
it is fitted with a standard 110 volt 2 prong line cord plug, a seven
pin male and a four pin female connector. The line cord plug connects
to
any 110-117
volt
AC. household outlet.The seven
pin
male
plug
connects to the receiver battery pack. The female connector located on
the lower left-hand side on the transmitter case.
Before connecting the charging cord, turn the transmitter switch off
and turn the receiver switch to the on position, (if your switch aren't
in the proper position, your system won't charge.) Next, plug the 4
socket connector to the transmitter and then the 7 pin plug into the
receiver battery pack. Then you plug the line cord plug into 110 volts
AC household outlet. Check the charging indicator light located at the
top right hand side of the transmitter, when this light is on, it indicates
that both batteries are being properly charged 18 to 24 hours is sufficient for 100% charge and this will operates your system for 3 hours.
TRANSMITTER:
LOCATED ON FRONT PANEL:
Two control sticks-4 trim levers-one lever for auxiliary (5th) channel
operation-output meter.
TOP PANEL:
On-off switch-Antenna mount-Charging light indicator.
BOTTOM PANEL:
Two thumb screws. Removing these screws allowsacess to battery compartment,
SIDE PANNE L:
Left side contains battery charging connectors.
THE CONTROLS PROVIDE THE FOLLOWING FUNCTIONS:
The left hand control stick operate throttle and aileron. To the right
of this stick is a trim lever which controls the idle position of the
throttle servo. Directly below the stick is the trim lever for aileron.
The right hand control stick operates rudder and elevator. The trim
lever located to the left of this stick control the neutral position of
the servo which is activated by moving the stick vertically. The trim
lever located directly below the right control stick is used to control
the neutral position of the servo that is activated by moving the stick
horizontally. The auxiliary or 5th channel is controlled by the lever
located Just below and to the left of the output meter. See diagram above. Each of the four main controls is trimmable by the four trim le-
vers.

this
system, since individual preferences for control stick length may vary.
Stick knob may be interchanged by merely pulling the knob directly away from the stick. The replacement knob should be pushed onto the
stick until it is fixed.
RECEIVER:
This receiver has been factory tuned and adjusted to the transmitter,
no further adjustments are requiredand the receiver should not be tampered with. Attach to the receiver is the antenna, one 7pin plug and
2 jacks. The seven pin plug connects the receiver battery pack and
supplies
power
to
the
receiver
and
servos.
The
multi
connectors
jack
is for the rudder, throttle, elevator and auxiliary the aileron servo.
See diagram below.
Note: Receiver connector has a white dot on one end. For auxiliary
(5th) channel, plug servo into this end of connector.
OPERATION CHECK:
1. Connect servo plugs to receiver jack, next connect receiver to bat-
tery pack.
2.Collapse transmitter antenna and turn the switch on. Next turn the
receiver switch on. All servos should stop at the neutral position.
3. Make sure that each of the servos operates correctly and responds to
the individual stick and trim lever. This test should be performed at
least 20 yards from the receiver. Don't test for longer than 5 minutes.
Futaba FP-T4 and FP-T5 are very high put type transmitters.
The receiver should be loosely mounted in foam rubber or foam plastic to protect against vibration and shock. Battery pack should also
be protected from vibration by wrapping in foam rubber. The receiver
should also be protected from fuel by wrapping it in a plastic bag.
The
receiver
antenna
must be kept
as
far
as
possible
from
other wiring
and metal parts. Excessive electrical noise is generated by metal to
metal connections and may seriously interfere with receiver reception.
Such metal to metal contacts, such as throttle linkage, should be made
with nylon devices This receiver has one of the most noise resistive
circuits on the market but care should be taken to keep electrical noise at a minimum.
PRE-FLIGHT CHECK:
The final check of the system should be performed with the engine
running at a distance of 20—30 yards with transmitter antenna retracted. If the distance is substantially less than with engine not running, you can be sure something in your installation is causing interference from excessive vibration.
When all the above test are concluded satisfactorily you are ready
for your first flight. If you have no previous experience with proprotional equipment, an experienced flyer should be enlisted to perform
the initial flying and trimming of the craft.
REPAIR SERVICE
To insure prompt service, please follow the instructions listed below.
The gears for repairing should be sent back to the distributor or local
dealer.
1. Charge batteries for at least 18 hours prior to the despatch.
2. Return only the system, separate from your installation. Remove
servos from mounts, remove foam padding from receiver.
3. Plugs or other modifications which interfer with factory testing
procedures will be returned to factory standards at your expense.
4. Carefully pack all components individually with sufficient packing
material to prevent shipping damage. Warranty does not cover any
components damaged in transit. Also, for your own protection, insure all packages.
5. Include a brief hut thorough explanation of all problems and service
required and tape to back of transmitter. Label servos as to their
function.
