TTX404 TRANSMITTER (Tx

The TTX404 airplane transmitter is available in either a “Mode 2” confi guration
with throttle on the left and elevator on the right, or “Mode 1” confi guration with
throttle on the right and elevator on the left. Mode 2 radios are most commonly
used in the U.S., whereas Mode 1 radios are popular in other countries. Be sure
the radio purchased is of the correct mode.

)

Four “AA” batteries are required to power the Tx (not included). Non-rechargeable

1.5V alkaline, or 1.2V rechargeable nickel-cadmium (NiCd) or nickel-metal hydride
(NiMH) cells, can be used. Do not mix cell types, or old and new cells, etc. See the

SERVOS AND ACCESSORIES section on page 16 for optional batteries available

at local hobby retailers.

To install the batteries, slide the
battery door down. Insert the cells as
shown in the diagram, making sure
to note proper polarity for each cell.
Close the battery door.

POWER SWITCH, LED, and
LOW BATTERY ALARM

The red power LED should light
when the power switch is moved
upwards to the “ON” position. The

2

Tx should have adequate power for fl ight when the LED is on constantly. Anytime
the LED begins to fl ash, accompanied by the sounding of an audible tone, the Tx

battery voltage has dropped too low and operation of the model should NOT

be attempted!

WARNING! Never operate an R/C model with weak Tx batteries!
Reduced operational range and/or possible loss of control of the
aircraft could result. Replace weak alkaline batteries, or re-charge
NiCd or NiMH batteries before attempting a fl ight!

If during a fl ight the Tx LED starts to fl ash, accompanied by the sounding of audible
tones, it’s a warning that the Tx batteries have become weak and the aircraft should
be landed as soon as possible!

AILERON (CH1)

Controls the moveable surfaces at the end of both main wings to rotate the airplane
about the “roll” axis (an imaginary line which extends from the airplane’s nose to
the tail). Since every airplane is different, the aileron reversing switch must be set
so that moving the aileron stick to the right will cause the airplane’s right aileron to
defl ect up, thus causing the right wing to drop and the airplane will bank to the right.
Moving the aileron stick to the left will cause the airplane’s left wing to drop and the
airplane will bank to the left. This is one important method for turning the aircraft.

ELEVATOR (CH2)

Controls the moveable horizontal surfaces on the airplane’s tail to rotate the airplane
about the “pitch” axis (an imaginary line extending through the center of both main
wings, from one wing tip to the other wing tip). Position the elevator reversing switch
so that pulling the elevator stick back (towards you) will cause the elevators to
defl ect up, thus causing the nose of the airplane to rise. Pushing the elevator stick
forwards (away from you) will cause the nose of the airplane to drop. When using
the ailerons to bank the airplane’s wings, pulling the elevator stick back will help the
aircraft maintain altitude and turn the aircraft more quickly.

THROTTLE (CH3)

Controls the speed (R.P.M.) at which the engine or electric motor operates. With
the throttle reversing switch in the NOR position, pulling the throttle stick back will
cause the engine’s speed to decrease. Pushing the throttle stick forward will cause
the engine’s speed to increase.

RUDDER (CH4)

Controls the sideways movement of the airplane’s tail and will rotate the airplane
about the “yaw axis” (an imaginary line from the top of the airplane’s fuselage to
the bottom of the fuselage, located near the center-point of the fuselage). Position
the rudder reversing switch so that moving the rudder stick to the right causes the
rudder to defl ect to the right, thus causing the nose of the airplane to point to the
right. Moving the rudder stick to the left will cause the nose of the airplane to turn

3

left. When using the rudder in conjunction with the ailerons, the airplane’s nose can
point into a turn (instead of pointing up and “skidding” through the turn), allowing the
airplane to perform tighter, more coordinated turns.

TRIMS

A “trim” lever is included for each of the main controls, located adjacent to the
respective stick.

The aileron, elevator, and rudder trim levers are digital in function, and always rest
at center position. Briefl y defl ecting the lever to either direction away from center
will cause the respective servo output to fi nely rotate to one direction, and will be
accompanied by an audible tone. Pressing and holding the trim lever will cause
the servo output to move repeatedly. During a fl ight, when the main sticks are
released and spring back to center position, the aircraft should ideally not veer in
any direction. If the aircraft does veer in a particular direction, click the respective
trim lever until the aircraft maintains a straight attitude on its own.

The throttle trim lever is analog in function, and can move mechanically up or down
and rest at any point in the range. Moving the throttle trim lever slightly up or down
will fi nely adjust the engine or motor at low speeds. For safety reasons, it’s a good
idea to use throttle trim when controlling the engine/motor at very low speed while
on the ground. For aircraft with glow engines, the precise position of the trim lever is
helpful when determining the engine’s preferred idle point. The throttle trim lever is
not active when the main throttle stick is above the center point.

REVERSING SWITCHES

Four reversing switches are built into the Tx, one for each control. Each switch
can reverse the rotational direction of the servo that is connected to the respective
channel. This is often a much easier method for changing the direction of a servo’s
movement as opposed to altering the mechanical connections between the model’s
surface and the servo. Refer to the model’s instructions for specifi c details.

ADJUSTABLE STICKS

4

The length of both gimbal sticks
can be adjusted as desired.
Loosen the set screw inside
the center of the stick with a
2mm hex wrench. Rotate the
stick end counter-clockwise to
lengthen the stick, or clockwise
to shorten the stick. Once the
desired stick length is found,
tighten the set screw with the
hex wrench.

CHARGE JACK

WARNING!! Do NOT attempt to recharge alkaline batteries! The
charge jack should ONLY be used if rechargeable cells are used
in the transmitter.

The TTX404 includes a built-in charge jack for convenient recharging of NiCd or
NiMH batteries, and is compatible with charge leads designed for Futaba® brand
transmitters. (HCAP0101) This jack is NOT compatible with charge leads for Hitec®,
Airtronics®, JR® or Spektrum® radios. The dimensions for compatible charge plugs
are as shown in the picture below.

To use the charge jack with optional rechargeable batteries, fi rst remove the sticker
that covers the charge jack on the side of the Tx – making sure not to allow any
object to be inserted inside the jack itself. Next, insert the cells inside the Tx’s battery
compartment noting proper polarity. Make sure the transmitter’s power switch is in
the OFF position. Connect a compatible charge lead to the jack and follow the
instructions included with the charger for charging of NiCd or NiMH batteries that
are rated at 4.8V.

Tactic’s optional TACP1000 rechargeable battery and wall charger kit includes eight
“AA” size rechargeable NiMH cells and 110V AC wall charger, which is compatible
with this Tx and can be found at local retailers. Make sure to follow the instructions
included with the charge kit.

WARNING!! It’s not recommended to charge batteries at greater
than 1 amp through this charge jack. Fast charging of NiCd and
NiMH batteries should ONLY be done with chargers that are

specifi cally designed to include the peak-detection function
which can automatically stop charge when full charge is detected. Misuse,
improper charging, or over-charging of rechargeable cells can result in
damage to the cells that could include cell rupture, explosion, or fi re!!

TRAINER FUNCTION

The TTX404 Tx includes a built-in wireless trainer function – no trainer cable

required! This trainer system connects a teacher’s Tactic Tx to a student’s Tactic Tx
by wireless connection. Tactic’s wireless trainer function is not compatible with
trainer systems in any other brand radios.

IMPORTANT! Before attempting to fl y the airplane, it’s very important

to make sure all reversing switches and trim lever adjustments on the

student’s Tx match the settings on the teacher’s Tx! Otherwise, the

airplane could suddenly veer off in an unwanted manner when the
teacher’s trainer switch is pressed. Proper matching of the student and teacher’s
Tx settings should ensure that no unexpected movements occur when the trainer
switch is pressed. This is especially true of the throttle control!

1. The Tx that was used to setup the controls on the aircraft must be used by
the TEACHER.

2. The student must use a separate Tactic Tx with wireless trainer function.

3. Place the teacher and student’s transmitters within 1 meter of each other,
and make sure the throttle stick for each Tx is set to idle.

4. Turn ON the power switch for the Tx being held by the student.

5. Pull and hold the trainer switch on the teacher’s Tx, and then turn ON the
teacher’s Tx power switch.

6. The LED on the teacher’s Tx will fl ash 3 times to indicate it has become
bound with the student’s Tx.

7. The teacher can then release his trainer switch.

8. Once both transmitters are bound together, power can be applied to the
receiver to prepare for fl ight.

When the training session has ended, with the model on the ground and all power
removed from the model, place both transmitters within 1 meter of each other and
simply turn the power switch for both transmitters to the OFF position. This will
terminate the wireless link between both transmitters. If additional training will be
performed again, return to step 1 above to re-establish the wireless link between
the teacher and student’s transmitters.

ELEVON & V-TAIL MIXING FUNCTIONS

The TTX404 includes elevon and V-tail mixing functions, which can be turned on or
off. “Elevon” control consists of a mixture between the elevator and aileron channels,
and is useful for certain types of aircraft (such as a fl ying wing). “V-tail” control consists
of a mixture between the elevator and rudder channels and is useful for aircraft which
have a V-tail. The default setting for all mixing will be “off”. To change the mix setting:
