TTX402 TRANSMITTER (Tx

)

The TTX402 4-Channel Micro airplane transmitter can be confi gured to operate
as a 3-channel or 4-channel Tx. When confi gured for 4-channel operation the
controls function like a normal Mode-2 transmitter with aileron + elevator on the
right stick, and throttle + rudder on the left stick.

Confi guring the Tx for 3-channel operation can help beginners concentrate on
throttle control with one hand and full airplane directional control with the other
hand. Here , the right stick operates ele vator + rudder while the left stick will control
the throttle. The aileron function will still be active, and now be on the left stick,
but aileron control is often not needed for 3ch aircraft. See the diagram above for
details.

To change the TTX402 transmitter between 3ch and 4ch confi gurations:

1. Turn off the Tx power switch.

2. Move the right stick to the top-right corner, and the left stick to the top-left
corner, and hold in these positions.

3. Move the Tx power switch to the On position. The power LED will fl ash,
accompanied by three short tones from the Tx which indicates the Tx
confi guration has been changed.

Note that each time the Tx pow er switch is turned on you will hear either one short
tone if the Tx is in the 3ch confi guration, or two short tones if the Tx is in the 4ch
confi guration.

TACJ2402 Mnl.indd 2TACJ2402 Mnl.indd 2 4/20/2011 9:51:26 AM4/20/2011 9:51:26 AM

INPUT POWER

Five “AA” batteries are required to power the Tx
(not included with individual radio systems). Non­rechargeable 1.5V alkaline, or 1.2V rechargeable
nickel-cadmium (NiCd) or nickel-metal hydride
(NiMH) cells can be used. Do not mix cell types,
old and new cells, etc. See the SERVOS AND
ACCESSORIES section on page 12 for optional
products available at local hobby retailers.

Slide the battery door down, and insert the cells. Make sure to note proper
polarity for each cell. Reinstall the battery door.

POWER LED, and LOW BATTERY ALARM

The power LED should light when the power switch is moved upwards to the on
position. The Tx should have adequate power for fl ight when the LED is on
constantly. Anytime the LED begins to fl ash, accompanied by 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 audible tones sound and the power LED starts to fl ash the Tx
batteries have become weak and the aircraft should be landed as soon as possib le!

AILERON (CH1)

Controls the moveable surfaces at the trailing edge of the 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 direction of movement for
the aileron channel may need to be reversed 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. When the Tx is set to the 3ch
confi guration the aileron channel will not be used.

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). The direction of mo vement f or the elev ator
channel may need to be rev ersed so that pulling the elev ator stick back (tow ards you) will
cause the elevator to defl ect up, thus causing the nose of the airplane to rise. Pushing
the elevator stick forward (a way from you) will cause the nose of the airplane to drop.

TACJ2402 Mnl.indd 3TACJ2402 Mnl.indd 3 4/20/2011 9:51:26 AM4/20/2011 9:51:26 AM

THROTTLE (CH3)

Controls the speed (R.P.M.) at which the motor operates. Pushing the throttle stick
forward will cause the motor’s speed to increase. Pulling the throttle stick back will
cause the motor’s speed to decrease. Always place the throttle stick at the low
position before switching on the transmitter.

RUDDER (CH4)

Controls the side-to-side movement of the airplane’s tail and will rotate the airplane
about the “ya w 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). The direction
of movement for the rudder channel may need to be reversed 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 left. When the Tx is set to the 3ch confi guration the
rudder will be controlled by the right stick. Otherwise, rudder is controlled with the
left stick.

TRIMS

All trims are digital in function. Two trim buttons are included for each of the main
controls, located adjacent to the respective stick. One trim button adjusts the
servo’s direction in one direction, and the other button to the opposite direction.
Briefl y pressing any trim button will adjust the center position of the respective servo
output in the appropriate direction and will be accompanied by an audible tone.
Pressing and holding any trim button will cause the servo output to move repeatedly.
A unique tone will sound when the servo reaches either end of the trim limit, and at
the channel’s center point.

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, press the respective trim button until the aircraft maintains a
straight attitude on its own.

REVERSING CHANNEL DIRECTION

The direction of movement f or any of the four channels can be reversed electronically .
To change the direction of movement for any channel:

1. Switch off the Tx power switch.

2. Press and hold either trim button for the channel to be reversed.

3. Switch the Tx power switch on. The LED should fl ash to indicate the movement
for that channel has been reversed.

4. Repeat steps 1-3 to reverse the direction of any other channel as needed.

5. Switch the Tx power switch off.

BUILT-IN 1S LIPO CHARGER

A 1S LiPo charger is b uilt into the TTX402 tr ansmitter itself. This charger is designed
specifi cally for charging a micro 1S 3.7V LiPo cell ha ving a micro connector . Charge
current is rated at 250mAh, with a maximum charge voltage of 4.20V. Charging will
begin automatically when the battery is connected, and automatically stop when full
charge is detected. It is not recommended to charge a 1S LiPo while fl ying.

1S LiPo Battery

ttery

1. Make sure the Tx power switch is in the off position.

2. Looking at the rear of the Tx, slide open the charger door b y moving it to the right.

3. Connect the 1S LiPo battery to the sock et inside the battery door . When a proper
connection has been made and the battery is being charged, the “CHARGE” LED
will illuminate.

4. When charge is complete the CHARGE LED will turn off.

.IMPORTANT WARNINGS REGARDING LIPO BATTERY USE!!

NEVER A TTEMPT TO CARE FOR LITHIUM-POLYMER (LiPo) CELLS
IN THE SAME WAY AS OTHER BATTERY TYPES! LiPo cells are much

more sensitive and volatile than NiCd or NiMH batteries. Misuse and

overcharge can quickly result in LiPo cells getting hot and/or swelling,
which could lead to VIOLENT EXPLOSION AND/OR FIRE and serious personal
injury and property damage.

● NEVER attempt to recharge other batter y types except 1S LiPo cells with this

built-in charger.

● NEVER continue to charge or use LiPo cells if they start to swell or become

overly warm to the touch. Failure to follow this guideline could cause the battery
to become hot and explode or ignite!!

● ALWAYS disconnect the battery from the charger immediately if the battery

becomes hot! Allow the battery to cool before use.

TACJ2402 Mnl.indd 5TACJ2402 Mnl.indd 5 4/20/2011 9:51:26 AM4/20/2011 9:51:26 AM

● NEVER allow water, moisture or foreign objects into the Tx/charger.

● NEVER leave the room where a battery is being charged.

● NEVER place the Tx/charger or battery on a fl ammable surface or near a

fl ammable object during the charge process. Keep away from carpets, cluttered
workbenches, etc.

● ALWAYS have a “class D” fi re extinguisher available when handling LiP o batteries.

● If a LiPo cell leaks fl uid, do not get fl uid on the skin, in the eyes or mouth, etc. If

you make contact with fl uid from a LiPo battery, rinse the affected area well with
water and seek immediate medical care.

The optional TR421 4-Channel Rx Control Board integr ates a T actic 2.4GHz receiver ,
two linear actuation servos, and a 3A brushed ESC onto one device. Sockets are
mounted on the board for connection of an optional servo actuator such as the
Tactic TSX21 Linear Servo Actuator (TACM0021), and an external brushless ESC.

BIND THE RECEIVER TO THE TRANSMITTER

If included with the TTX402, the TR421 Rx will auto-bind with the transmitter once
powered. This bind ensures sole communication between the two, and prevents
other transmitters from controlling your model. If it’s necessary to re-bind the board
to the transmitter:

1. Switch on the Tx.

2. Connect the battery to the Rx Control Board. Only use single cell, 3.7V LiPo

batteries with a micro connector with the TR421 Rx Control Board. See SER VOS
AND ACCESSORIES on page 12 for recommendations.

3. The Rx LED on the bottom side of the board will tur n on, indicating the Rx is

bound to the Tx.

4. Test for proper Tx / Rx functionality in the next section. If the system did not

become properly binded, repeat steps 1-3 above.

TACJ2402 Mnl.indd 6TACJ2402 Mnl.indd 6 4/20/2011 9:51:27 AM4/20/2011 9:51:27 AM

RECEIVER AND SERVOS

Mount the TR421 4-Channel Rx Control Board as specifi ed in the model’s
instructions. The built-in receiv er is compatible with Tactic brand 2.4GHz transmitters
only. Make sure the airplane’s control pushrods can easily reach the arms of the
actuators, and are completely unobstructed.

To connect the airplane’s control
pushrods to the servo levers, fi rst center
the trims on the transmitter. Make sure
the servo’s arm is moved to a position
that will allow for full control of the
airplane’s surface in both directions once
the control rods are connected. This can
be tested by moving the Tx sticks to
maximum positions several times while
observing the movement of the control
surfaces. If a servo is binding or sticks in fl ight, the pushrod must be re-adjusted so
as not to drain excessive current from the battery and thus shorten fl ight time.

EXTERNAL SERVO CONNECTION

A socket is provided on the Rx Control Board for the addition of a separate servo (see
picture on page 6). If the Tx is confi gured for 4ch operation, connecting a linear actuator
servo to this socket will allow for control of an airplane’s aileron surface (as well as
elevator, rudder, and throttle). See your local retailer f or Tactic’s TSX21 Linear Actuator
Servo (TACM0021), which connects directly to this slot.

BRUSHED ELECTRONIC SPEED CONTROL (ESC)

The integrated 3 amp ESC is designed for micro-size brushed motors only. Connect the
Rx Control Board’s two brushed motor leads to the brushed motor. To set up the ESC:

1. Turn on the TTX402 transmitter.

IMPORT ANT! Always make sure that power is applied to the transmitter

BEFORE applying power to the receiver and servos, and that the

throttle stick is at minimum (idle) position. Failure to do so could result

in the model becoming uncontrollable and cause a safety hazard.

2. Move the Tx throttle stick to the minimum position.

3. Set the Tx throttle trim to center.

4. Connect the battery to the Rx Control Board. Power will be confi rmed by the Rx

Control Board sounding one beep.

5. Arm the ESC by moving the throttle stick to full throttle, which will be accompanied

by a single tone. Return the stick to the minimum position, which will be
accompanied by two tones.

6. The ESC is now armed and ready for operation.

TACJ2402 Mnl.indd 7TACJ2402 Mnl.indd 7 4/20/2011 9:51:28 AM4/20/2011 9:51:28 AM

USING AN OPTIONAL BRUSHLESS ESC:

A socket is provided on the Rx Control Board for the connection of an external 1S
brushless electronic speed control. To use the Rx Control Board with a brushless
ESC instead of the on-board brushed ESC, simply connect the brushless ESC to
this socket. The on-board brushed ESC will automatically be de-activated.

SYSTEM CHECK AND OPERATION

WARNING! Dur ing all pre-fl ight preparations with the aircraft on the

ground, make sure the throttle stick remains at the minimum position

and do not stand the Tx upright on the ground. Carefully la y the Tx on its

back on the ground to prev ent it from falling o ver and possibly dislodging
the throttle stick from the low position which would create a safety hazard. Make
sure all devices are properly mounted inside the model, and all wiring connections
are secure to prevent them from easily becoming dislodged during fl ight. For safety
it’s best to check the system with the propeller removed from the aircraft.

1. Once all connections are made, check the general oper ation of the radio and
all other components before attempting a fl ight.

2. Move the Tx throttle stick to the minimum (idle) position.

3. Turn on the Tx, and then the Rx.

4. Make sure all controls are operating in the proper direction. If any servo is
turning in the wrong direction, change the reversing for that particular channel.

5. With both sticks at center position, move the trims for the aileron, ele v ator, and
rudder channels so each respective control surface is perf ectly aligned with the
main surface. For example: When the aileron trim is at center it’s best that the
trailing edge of the aileron is aligned with the trailing edge of the wing itself (not
above or below the wing’s trailing edge).

6. Make sure that mov ements of the throttle stick result in an equal adjustment
of the motor R.P.M. in the model.

7. Perform a “range check”. The “range” is the safe operating distance
from the Tx to the Rx, and should be 150 meters. With the assistance of
another person, place the aircraft on the ground and walk 100 feet (30m)
away from the model. With the Tx pointed directly at the model, operate
the transmitter’s controls, and ensure the movement of all surfaces is
according to the movement of the transmitter.

8. Anytime power is to be removed from the radio system, it’s important to
shut down power in the aircraft fi rst. Otherwise, the aircraft could become
out of control and cause a safety hazard! Move the throttle stick to minimum
position to shut down the ESC. Once the propeller has stopped rotating, shut
off the ON/OFF power switch in the model, and disconnect the po wer battery
from the ESC in electric airplanes. Then turn off the power switch in the Tx.

FLYING THE AIRCRAFT

1. Once all setup procedures have been confi rmed, and power has been
removed from the model and transmitter , re-attach the propeller to the model.

IMPORTANT: Be very careful to stay clear

from moving propellers!!

2. Make sure the airplane’s power batteries are fully charged.

3. Move the Tx throttle stick to minimum position, then switch on the Tx power
switch. Turn on the power switch in the model.

4. During the fi rst fl ight, it might be necessary to re-trim the aileron, elevator,
and rudder channels to allow the airplane to sustain level hands-off fl ight. If
further adjustments are required on the ground, beware that the on-board
brushed ESC will still be active (if used).

5. When the fl ight is completed, remove power from the system as described
before. Shut down power to the Rx Control Board fi rst, then the transmitter.

IMPORTANT WARNINGS AND PRECAUTIONS

● NEVER allow water or moisture to make contact with the electronic
components inside the transmitter, receiver, servos, etc.! This could
lead to failure or improper functionality of components and poor control
of aircraft which could pose a safety hazard.

● NEVER operate R/C model aircraft near power lines, r adio or cell phone tow ers ,

roads or automobiles, buildings, or pedestrians. Be very careful in locations
where many R/C aircraft are being used simultaneously.

● NEVER operate R/C equipment if you are physically impaired as it could pose a

safety hazard to yourself or others in the area.

● NEVER allow small children to operate/control model R/C equipment without the

supervision of an adult.

● NEVER allow the transmitter’s throttle stick to accidentally be moved away from

the “off” or minimum position while the model’s engine/motor is moving.

● ALWAYS range check the radio system before use.

● ALWAYS make sure that all transmitter stick movements operate all servos

properly in the model. Check the proper oper ation of control surf aces bef ore and
after starting the motor.

● Do not store your radio equipment in extremely hot or cold locations, in direct

sunlight, or in locations with high humidity. Store R/C equipment in cool and
dry locations.

TACJ2402 Mnl.indd 13TACJ2402 Mnl.indd 13 4/20/2011 9:51:29 AM4/20/2011 9:51:29 AM

● Do not allow chemicals to come in contact with any parts of the radio system.

Substances such as glow fuel, gasoline, CA glue, etc. could permanently
damage plastic parts of the radio system.

● If NiCd batteries were installed in the transmitter, remove the batteries before

placing the radio in long-term storage.

TROUBLESHOOTING

RANGE IS SHORT

Interference – check Rx antenna installation. Rx may need to be located to a
different position in the model for better reception. Low Tx or Rx battery – replace
the batteries or recharge if applicable. Crash damage – send the radio to Hobby
Services for repair.

RUN TIME IS SHORT

Low Tx or Rx batteries – replace or recharge the batteries. Obstructed servo
linkages causing excess battery drain – free the linkages / pushrods.

Tx POWER SWITCH ON BUT SERVOS DO NOT FUNCTION
