BATTERIES
4
• Remove the rear cover of the transmitter as shown in Fig. 4 and load the 7 pen-cell bat­teries in the correct polarity.
• Extend the antenna fully and set the POWER switch to ON. The meter pointer should de­flect to the green zone. If the meter pointer does not move, or moves very little, check for poor battery contact, incorrect battery polar­ity, or faulty batteries.
• When the meter pointer enters the red zone, the range of the radio waves will become short. Change the batteries when the meter pointer drops to the boundary between the red and green zones.
• Use the trim lever to fine adjust each rudder. This lever can also be used to adjust the neu­tral position and the flight posture after the mechanism has been mounted. However, after test flight, all adjustments should be made with the rod adjusters, etc. and the lever handle should be left in the neutral position as much as possible.
• The throttle stick neutral position can be selected in 5 steps by moving the neutral lever as shown in Fig. 2. Adjust the neutral position to match the ap­plication.
•With the NiCd system FP-T3EG, recharge the
battery as shown in Fig. 6(B). The NT-8C is already installed.
• To change the elevator stick from a self­neutral type to a ratchet type, install the slide plate and remove the spring and stick arm as shown in Fig. 3.

•With the battery system, insert the four
dry-cell batteries, being sure that the polar-
ity is correct, then firmly tighten the coin screw.
• Connect the servo and switch as shown
Fig. 9. Then extend the transmitter
ceiver antennas fully.
•Set the transmitter POWER switch
then set the receiver POWER switch to ON.
The servo will stop near the neutral tion. Operate each stick of the transmitter and check that the corresponding servo faith­fully follows the movement of the stick.

posi-
then
re-
check that the direction of servo matches the direction of transmitter stick.
•Operate each servo horn over its entire
in
operating range and check if the pushrod is too tight or too loose. Applying unreasonable force to the servo
horn will adversely affect the servo and quickly drain the batteries. Always make the operating width of each rudder somewhat larger than the full stroke (including trim) of the servo horn. Adjust the servo horns so that they oper­ate smoothly even when the trim lever and stick lever are operated simultaneously in the same direction.

• Be alert for noise.
6
If engine vibration causes metal parts to touch, noise will be produced and the re­ceiver and servos may operate incorrectly. We recommend the use of noiseless parts.
• When installing the switch, cut a rectangu­lar hole somewhat larger than full stroke of the switch and install the switch so that it moves smoothly from ON to OFF. When the switch is mounted inside the fuselage and is turned ON-OFF with wire, install the switch mount in the same manner. Install the switch where it will not come into direct contact with the engine oil,
dust, etc.
• Even though the receiver antenna is long,
do not cut or bundle it.
• Install the servo firmly. Refer to Pig. 10 at
the right.
•A spare servo horn is supplied. Use it as
needed. Do not forget to install the tooth washer when changing the horn.
•Wrap the receiver in sponge rubber. Place
the receiver in a plastic bag and wrap a rubber band around the open end of the bag to waterproof and dustproof the re-
ceiver.
Do
the
same
with
the
receiver bat-
tery.
• Also use the rubber bands wrapped around
the receiver to hold the servo and switch
leads.
•After mounting is complete, recheck each part, then make the transmitter antenna as
short as possible, extend the receiver an­tenna fully, and operate the set from a dis-
tance of 22 to 33 yards (20 to 30m) for
range check. The movement of each servo should follow the operation of each stick
of the transmitter.
•THROTTLE -> RUDDER MIXING ADJUSTMENT
The rudder neutral position at engine SLOW and engine HIGH depends on the engine torque. When adjusted for straight ahead when a common 2-cycle glow plug engine is at HIGH, the boat will slowly swerve to the left at SLOW and if adjusted for straight ahead when the engine is at SLOW, the boat. will slowly swerve to the right at HIGH. Mix-
ing from throttle to rudder, the biggest feature of the Model FP-3EG, completely eliminates this tendency.
The following description is for a common 2-
cycle glow plug engine that rotates counter-
clockwise. Reverse the description for a gasoline
engine, electric motor, etc. that rotates clock­wise.
This mixing is adjusted with the mixing trimmer and limit point trimmer at the left front of the transmitter. Mixing trimmer 6 adjusts the amount and
direction of movement of the rudder servo when the throttle stick is moved up and down. The mixing amount is zero at the center position. Limit point trimmer 7 changes the point at which the operating line of the mixing amount to the rudder servo curves when the throttle stick is moved from LOW to HIGH.
1 When the throttle stick is set to HIGH, a
boat moving straight at engine control SLOW will swerve to the right. On the other hand, a boat moving straight ahead at throttle HIGH will swerve to the left when the throttle stick is set to SLOW. That is, the rudder servo should be turned to the right when the throttle stick is set to SLOW.
2 Turn the mixing trimmer with a screw-
driver so that the rudder turns slightly to the right when the throttle stick is moved from HIGH to SLOW.
You should now have a good understanding of throttle to rudder mixing. Throttle -> rudder mixing will be called
"MIX" hereafter.
3
Run the boat without MIX (MIX trimmer at center) and check the rudder neutral, play, and engine SLOW and HIGH.
• Limit point Turn the trimmer about
2/3 clockwise.
(In the L to H direction.)
•Under
this
state,
turn the MIX trimmer about halfway in the R (right) direction and check the rudder movement (rudder servo) while moving the throttle stick up and down. The rudder should move a little to the right at SLOW and a little to the left at HIGH.
•Set
the
MIX
trimmer
to
zero (center) at throttle stick HIGH. The rudder servo should not move because the mixing amount is zero at throttle HIGH as shown in
Fig. 11.
4 After all preparations are complete, make
adjustments while actually running.
A Adjust the rudder trimmer so that the
boat travels straight ahead at throttle HIGH.
B Set the throttle stick to SLOW. If the
boat
swerves
to
the right
at
this
time,
the MIX amount is excessive. Reduce the MIX amount by turning the MIX trimmer
toward the center. If the boat slowly swerves to the left, the MIX amount is in­sufficient. Increase the MIX amount by turning the MIX trimmer in the R direc­tion.
C This completes MIX adjustment at throt-
tle SLOW and HIGH. However, adjust­ment near medium SLOW is still neces­sary. To adjust near medium SLOW, proceed as follows:
7
(a) If the boat slowly swerves to the right
when the throttle stick is set to medi­um SLOW, the POINT is too high. Adjust it by turning the limit point trimmer counterclockwise. Then re­adjust item B above.
(b) If the boat slowly swerves
the POINT is too low. Adjust by turn­ing the limit point trimmer clockwise. Then readjust the MIX trimmer as described in item
RUDDER DUAL RATE (DUAL-RATE ON,
DUAL-RATE OFF)
•Rudder dual rate switch Dual-rate (servo stroke becomes narrow) is effected when this switch is set to ON. Dual-rate is off when the switch is set to OFF. OFF is the normal state.
• Rudder dual rate trimmer
This trimmer adjusts the full stroke of the servo when the rudder dual rate switch is set to ON. Adjust it to match the course and technique. The rudder dual rate amount is continuously variable from 40% to
100%.

Digital Proportional Frequencies
Band Band Band Band
Band
The frequency of Futaba digital pro-
portional sets can be changed among bands (1)~(5) on the 27MHz band
only.
However, a 27MHz band set cannot be changed to 72MHz band, and vice versa.
Therefore, always attach the correct frequency flag to the end of the transmitter antenna. Each frequency
band has its own designated color, as stated above.. The frequency flag is in-
tended for identification purposes. Also change the frequency flag when changing the crystal.
Futaba paired crystals are precisely
matched. Always use a Futaba crystal set (transmitter, receiver) when chang-
ing the frequency.
It is illegal to change crystals of trans­mitter on the 72-76 MHz bands in the
U.S.A.
