INPUT POWER: This transmitter (Tx) requires four “AA”

batteries. Non-rechargeable 1.5V alkaline or rechargeable

1.2V nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) cells can be used (not included). Do not mix old and new cells, or mix non-rechargeable alkaline cells with rechargeable NiCd or NiMH cells, etc. See the Accessories section at the end of this manual for optional batteries.

To install the batteries, slide open the battery door. Install the batteries as shown in the diagram. Make sure to note the proper polarities on each cell. Close the battery door.

Page 3

CHARGE JACK: A built-in charge jack is included for recharging of NiCd or NiMH

rechargeable batteries. This jack can accept charge leads designed for Tactic brand transmitters, with the center pin being positive polarity. This jack is NOT compatible with charge leads designed for other radio brands. If using rechargeable batteries, make sure to only use a charger which is compatible with those battery types. Make sure the Tx power switch is OFF to charge the batteries through the charge jack. Connect the charge lead to the charger ﬁ rst, then to the Tx charge jack. Follow the instructions included with the charger. Charge leads such as TACP0101 – Tx Rx Charge Leads from Tactic are recommended for use with this transmitter.

IMPORTANT: Do not operate an R/C model with weak batteries as it could result in reduced range and/or possible loss of control. Failure to

obey this warning could result in destruction of the model and possible bodily injury. Only use the charge jack to recharge rechargeable cells. Never attempt to recharge alkaline batteries. Do not accidentally short circuit the terminals inside the charge jack as permanent damage could result and void the warranty. Do not charge batteries at currents greater than 1 amp through this charge jack. 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!!

ON/OFF POWER CONTROL AND LED WITH LOW BATTERY ALARM:

Move the power switch to the “ON” position. The red LED should illuminate. If the LED stays on constantly the batteries have ample power for a ﬂ ight. If the LED is ﬂ ashing, and also accompanied by beeps, the transmitter’s batteries have become weak and require replacement or recharge prior to attempting a ﬂ ight. If this alarm activates during ﬂ ight land the aircraft immediately to avoid a possible loss of all control!

GIMBAL STICKS: The length of each control stick can be adjusted for preferred feel. With a 5/64" hex wrench, loosen the set screw inside the tip of the stick. Turn the tip of the stick counterclockwise to lengthen the stick. Turn the tip of the stick clockwise to shorten the stick. Tighten the set screw once the desired length is found.

AILERON: Channel 1 controls the airplane’s ailerons. These moveable surfaces at the end of the wings rotate the airplane about an imaginary line which extends from the airplane’s nose to the tail called the “roll axis”. Moving this stick to the

Page 4

right should cause the aileron on the right wing to move upwards, causing the right wing to dip and bank the plane to the right. Conversely, moving the stick to the left should cause the left wing to dip and bank the plane to the left. If movement of the stick causes the aileron surfaces to move in the opposite direction, move the reversing switch for aileron channel 1 to the opposite position.

ELEVATOR: Channel 2 controls the airplane’s elevator. These moveable surfaces on the tail rotate the airplane about an imaginary line which extends through the center of both wings from wing tip to wing tip, known as the “pitch axis”. Moving the elevator stick upwards should cause the plane’s elevators to move upwards, causing the nose of the airplane to rise. Moving the stick down should cause the plane’s elevators to move down, and cause the nose of the airplane to drop. If movement of the stick causes the elevator surface to move in the opposite direction, move the reversing switch for elevator channel 2 to the opposite position. To help maintain the airplane’s altitude while performing a bank turn, gently pull back on the elevator stick while deﬂ ecting the ailerons.

THROTTLE: Channel 3 controls the airplane’s throttle. Pushing the throttle stick forward should cause the R.P.M. of an electric motor or combustion engine to increase. Pulling the throttle stick down (away from the Tx handle) should cause the motor or engine’s R.P.M. to decrease. If movement of the stick causes the throttle to move in the opposite direction, move the reversing switch for throttle channel 3 to the opposite position.

RUDDER: Channel 4 controls the airplane’s rudder. This moveable surface on the tail moves sideways and rotates the airplane about an imaginary line from the bottom of the airplane’s fuselage upward through the center to the top of the fuselage, known as the “yaw axis”. Moving the rudder stick to the right should cause the rudder to move to the right, and cause the airplane’s nose to point to the right. Moving this stick to the left should cause the rudder to move to the left, and cause the airplane’s nose to point to the left. Using the rudder along with aileron controls can point the airplane’s nose into a turn without pitching up or sliding through the turn. If movement of the stick causes the rudder surface to move in the opposite direction, move the reversing switch for rudder channel 4 to the opposite position.

TRIMS: Each of the four channels includes a trim lever, located directly adjacent to the main control stick. Trim levers are used to ﬁ nely adjust the center position of the respective channel.

The trims for aileron, elevator, and rudder channels function digitally. The levers always rest at mechanical center position. Brieﬂ y pressing the spring-loaded lever to either side of center position will adjust the center position of the respective channel electronically, and can be observed on the servo. Holding the trim lever to either side of center will cause the servo output to rotate repeatedly. Finely trim each of these channels so that during ﬂ ight the model does not veer in an unwanted direction when the main sticks are released and back at center position.

The throttle channel includes a “mechanical” or analog trim lever. This trim lever can be physically moved up or down and rest at any point in the range of movement. The mechanical position of the lever will adjust the throttle channel’s electronic position, and can be observed on the servo. This can ﬁ nely adjust the engine/

Page 5

motor’s speed, and is especially useful at low speeds when the model is on the ground - and only functions when the main throttle stick is below 50% full throttle. When using a combustion engine use the throttle trim to precisely determine the engine’s preferred idle point.

REVERSING SWITCHES: A reverse switch is included for each channel. Changing the position of a reversing switch changes the direction of movement for that respective channel. Moving the position of the reversing switch can often be the easiest way to alter the direction of a servo’s movement aside from making mechanical changes in the model. Refer to the transmitter’s faceplate to properly identify the different reversing switches. See the model’s instructions for speciﬁ c details relating to operation of the model.

TRAINER FUNCTIONS

The Tower Hobbies 424 radio includes a wireless trainer function. This radio can also be connected by wireless means to another Tower Hobbies 424 transmitter or Tactic™ brand transmitter having the wireless trainer function for the purpose of teaching a student how to ﬂ y. It’s not possible to connect this radio to other brand radios for wireless training. This radio can be used either by the teacher or student.

IMPORTANT! Before operating a model in training situations make

sure the reverse settings and trim adjustments for all channels match

on both the teacher and student’s transmitters. Failure to do this could cause the model to suddenly veer in an unexpected manner when the teacher’s trainer switch is activated. Proper matching of settings is especially important for the throttle channel!

1. Link the radio being used by the teacher to the receiver inside the model. Then turn the receiver’s power switch off.

2. Move the throttle stick for both the teacher and student’s transmitter to the idle position. Locate both the teacher and student’s transmitter within 1 meter of each other.

3. Turn the student’s transmitter power switch ON.

4. Pull and hold the trainer switch on the teacher’s transmitter. Then, turn the teacher’s power switch ON.

5. Observe the LED on the teacher’s transmitter. If it ﬂ ashes three times the teacher’s transmitter has linked to the student’s transmitter.

6. Release the trainer switch on the teacher’s transmitter.

7. After the transmitters are linked, power can be applied to the receiver inside the model and conﬁ rm the teacher has full control of the aircraft. Make sure both transmitters are kept within 15 feet of each other at all times while training.

8. During ﬂ ight, pulling and holding the teacher’s trainer switch will transfer control of the model to the student. Control of the model can be returned immediately to the teacher by releasing the trainer switch.

9. After the model is back on the ground and the training session has ended and power is safely removed from the model, turn OFF the power switch of both transmitters. This will break the wireless link between the transmitters. Return to step 1 above to re-establish the wireless link for additional training.

V-TAIL AND ELEVON MIXING

This radio includes mixing functions for controlling models having elevons on the wings or a V-tail. Certain model types have a tail shaped like a “V”, instead of the normal “T” shape. Mixing the transmitter’s elevator and rudder channels can allow for independent and combined control of both the “pitch” and “yaw” axes. Other airplane types, such as ﬂ ying wings or “delta” wing models, do not include a traditional tail with elevator surfaces. Yet, control of the model’s “roll” and “pitch” axes is still required. Mixing the transmitter’s elevator and aileron (“elevon”) channels can allow for independent and combined control of both the “roll” and “pitch” axes.

To set or change the mix setting:

1. As shown, with the transmitter power switch in the OFF position hold the right stick in the bottomright corner, and hold the left stick in the bottom-left corner.

2. Turn the transmitter power switch ON.

3. The LED should ﬂ ash. If two beeps also sound the v-tail mix has been activated. Check for proper operation of these channels. If the elevator or rudder controls inside the model move backwards, it may be necessary to trade the servo connections to channel 2 and channel 4 at the receiver. If V-tail is the desired mix move to the next section.

4. To instead activate the elevon (delta wing) mix, turn the Tx power switch OFF and repeat steps 1-3 above. Three beeps accompanying the ﬂ ashing LED indicates the elevon mixer is activated. If the elevator and aileron surfaces appear to move backwards it may be necessary to trade the servo connections to channel 1 and channel 2 at the receiver.

SPECTRUM

SERVOS: Servos are not included with this radio and must be purchased separately. Follow the instructions included with the model for installation of the servos. Center all trims on the transmitter. Connect linkages properly, but do not over-tighten the mounting screws as servos should have slight movement to compensate for engine vibration. Pushrods should be snug and not bind during movement, and allow the servo to have full range of movement by moving the Tx sticks to maximum rotational positions several times while observing the movement of the control surfaces. Adjust linkages as necessary to prevent unwanted battery drain due to linkage/pushrod obstructions. Connect the servos to the receiver as shown in the diagram. Make sure to install wires to not interfere with other moving parts inside the model.

ELECTRIC MODELS: For models using electric power for ﬂ ight, an optional

ESC (electronic speed control) is needed to control speed of the motor. Most ESCs also supply power to the receiver. Refer to the ESCs instructions to determine the

Page 8

proper way to connect the ESC to receiver output slot 3 (throttle). Make sure the transmitter’s throttle trim is at center, and follow the ESC instructions for connecting the battery and setup for operation. Most ESCs also include an ON/OFF power

switch to control power to the ESC/ﬂ ight system.

COMBUSTION MODELS: If using a glow or gasoline motor to power the model, a battery must be installed to supply power to the receiver and servos. “AA” NiCd or NiMH rechargeable batteries can be installed in the included battery holder (never use alkalines inside the model), or an optional assembled battery pack can be used. See the Accessories section on page 11 for battery options. The included switch harness can be connected between the battery and receiver, to conveniently turn power ON/OFF to the ﬂ ight electronics. Connect one end of the switch to the receiver’s battery socket, and the opposite end to the battery. The third lead on the switch harness is for connecting a battery charger for rechargeable batteries. Make sure the switch harness is in the OFF position to recharge batteries through the harness. Refer to the model’s instructions for installation recommendations for the receiver, battery, and switch harness.

LINK THE RECEIVER TO THE TRANSMITTER

Linking the 424 transmitter to the included receiver allows for direct communication between the two, and ensures no other radio equipment can interfere with operation.

Move the transmitter throttle stick to minimum. Turn the transmitter power switch ON

IMPORTANT! Always turn the transmitter on before the receiver, and move the transmitter’s throttle stick to minimum (idle) position. Otherwise the model could power out of control and possibly result

in personal injury and damage to the surroundings.

2. Turn the receiver switch harness or ESC switch to ON.

3. Link the receiver to the transmitter. Insert a small diameter screwdriver through the hole marked “LINK” on the receiver, and press and hold the button inside the hole. The receiver’s red LED will illuminate through the plastic case. Then, it will turn off after approximately one second. Release the pushbutton. The red LED will ﬂ ash once and then stay on if linking was successful.

NOTE: After the initial linking, when power is again applied to the system, if the receiver’s Rx LED ﬂ ashes once and then stays on, the Rx is already linked. There will be no need to re-link the receiver to the transmitter.

4. Test for proper operation of the transmitter and receiver system before use. If a link was not established, move the transmitter away from the receiver by a distance of approximately 3 feet. Then repeat steps 1-3 above to re-link.

Page 9

FAILSAFE FUNCTION

The failsafe function for this radio system is established in the receiver. If the control signal from the transmitter is suddenly lost, the receiver will automatically activate the failsafe. The aileron, elevator, and rudder channels (1,2, and 4) will hold the last positions as received. Throttle channel 3, however, can be set to move to a speciﬁ c position if desired. The factory default position for the throttle channel is minimum throttle (0%), and can be manually changed as follows:

1. Turn the transmitter power switch ON. Make sure all reversing switches are in the proper position for the application.

2. Turn the receiver’s power switch ON (switch harness, or ESC switch if used).

If an ESC will be used do NOT arm the ESC at this time. If the ESC has already been armed do not try to adjust the throttle’s failsafe position. If using a speed control which includes a safety feature for when radio signal is lost, the receiver’s failsafe function will instead control throttle operation. If using a combustion engine instead, do not adjust the throttle’s failsafe setting while the engine is running.

4. Move the Tx throttle stick to the position preferred for failsafe.

5. Press and hold the LINK button on the receiver. After the receiver’s red LED blinks twice, release the LINK button. The LED should then turn on and stay illuminated to indicate the failsafe position for the throttle channel is set.

PREFLIGHT CHECK

IMPORTANT! Remove the propeller from the aircraft before performing the ﬁ nal checks on the aircraft before a ﬂ ight. Always apply power to

the transmitter before applying power to the receiver. Make sure the transmitter’s throttle stick is at minimum position. Otherwise personal injury and damage to the surroundings could result if the model’s propeller begins to spin suddenly. If the transmitter must be set down, always lay it on its back so it cannot fall over and accidentally move the throttle stick away from minimum (idle) position. Check that all components inside the model are securely in place, including wires, connections, etc. so they cannot become separated during ﬂ ight.

1. Move the transmitter’s throttle to minimum position (idle).

2. Turn the transmitter’s power switch ON. Then apply power to the receiver.

3. Check for proper operation of all controls in the model by moving the controls on

the radio. Make sure servos are rotating in the proper direction and all linkages are moving properly.

4. With both transmitter sticks at center, check to make sure the transmitter’s

aileron, elevator, and rudder trim levers properly move their respective control surfaces, and align each control with the main surface on the model. Make sure the rudder is perfectly aligned with the tail’s vertical stabilizer, the elevator is perfectly aligned with the horizontal stabilizer on the tail, etc.

Page 10

Carefully check for proper control of the throttle. For electric powered models, when the throttle stick is at maximum the ESC should give the proper indications to identify full forward motion is active. When throttle is at minimum, the ESC should give the proper indications to identify power is off or zero throttle. For models with a combustion engine, conﬁ rm when the throttle stick is at maximum all connections on the engine allow it to reach maximum throttle. Conversely, conﬁ rm the engine stops entirely when the transmitter throttle stick is at minimum position.

6. Make sure the radio system passes a “range check” to conﬁ rm the safe operating

distance from the Tx to the Rx. With the aircraft on the ground, make sure full control of all surfaces exists at a distance of at least 100 feet (30 meters) away from the model. Point the transmitter directly at the model and conﬁ rm constant control exists.

7. When removing power from the airplane / radio gear, always turn off power

inside the model FIRST! Turn the transmitter power switch OFF second. Failure to follow this order could result in bodily injury and damage to the surroundings as the model could suddenly veer out of control. Move the throttle stick and trim positions to minimum to entirely stop movement of the propeller. Only after the prop has stopped moving completely, turn the receivers power switch (switch harness or ESC switch) to the OFF position. For electric models, then disconnect the battery from the ESC. Lastly, turn the transmitter power switch OFF.

FLYING A MODEL

1. Only after all setup and pre-ﬂ ight checks are complete, with power removed from

the model and transmitter, attach the propeller back onto the model.

WARNING! Always be mindful to stay clear of propellers after

power has been applied to the model!

2. If the model uses a combustion engine, make sure an ample amount of fuel is

in the tank. For electric powered models, make sure the battery is fully charged.

3. Carefully follow all instructions explained previously for applying power to the

transmitter and receiver.

4. Trim the aileron, elevator, and rudder channels as necessary during ﬂ ight so

the model can maintain a steady forward ﬂ ight without veering in an unwanted direction.

5. After the model is safely landed and the throttle stick and trim are moved to

minimum (idle), remove power from the model ﬁ rst, then lastly to the transmitter.
