SLT TECHNOLOGY, Tx-R,
AND COMPATIBLE RECEIVERS
Tactic’s custom SLT technology ensures that transmitters emit a strong, clear, frequencyhopping 2.4GHz signal, and that your compatible receiver accepts no signal except yours.
Binding Tactic brand receivers is as simple as pushing a button,
™which creates a locked-in, interference free link. The TTX650 radio can store up to 20 models in memory, making it perfect
to control a full fleet of models with the super-affordable Tactic brand 2.4GHz receivers.The TTX650 is also compatible with non-Tactic brand receivers which use the *SLT protocol, for the ultimate in convenience and fl exibility.
* Make sure optional receivers have the genuine SLT protocol before use with the TTX650.
|
TM |
The TTX650 is also compatible with all transmitter-ready |
|
|
|
|
|
aircraft bearing the “Tx-R” logo. Such aircraft include |
|
|
receivers having the SLT protocol. |
|
|
|
|

RECEIVER INSTALLATION
Always mount the optional receiver, servos, switch harness, battery, electronic speed control, etc. as explained in the manual included with such equipment and/or the model. Keep the Rx and its antenna(s) as far away from the engine/motor, servos, and ESC and other electronic items as much as possible. It may also be a good idea to mount the Rx inside certain models using Velcro,® and wrap it in foam rubber to prevent damage from strong vibrations or crash damage (except in extremely warm environments). It’s best to have as few items surrounding the receiver’s antenna tips as possible inside the model, to allow for the most obstruction-free signal path to the transmitter. Exposing the receiver’s antenna tip outside the model is recommended if possible. For receivers with two antennas, position the antennas at 90 degree angles with the tips resting at least 5 inches apart. If possible, allow one antenna to point vertically above the receiver itself.
TTX650 POWER SYSTEM
INPUT POWER
Four 1.5V “AA” alkaline cells (included) or 1.2V “AA” NiCd or NiMH cells supply power to the TTX650. Do not mix cell types, or old and new cells, etc. Slide open the battery door to fi nd the four “AA” cell battery holder. Insert all cells with the proper polarity as shown inside the battery holder. Carefully tuck the wires and battery holder inside the battery compartment so not to damage them when closing the battery door.
Alternatively, an assembled 4.8V NiCd or NiMH “AA” fl at pack can be installed. Remove |
5 |
the alkaline cell holder from the battery compartment and carefully observe the polarity |
|
|
of the wires before disconnecting the plug from the Tx. Install the NiCd or NiMH battery by fi rst inserting its connector into the jack in the battery compartment.
Battery voltage is shown on the LCD’s home screen for easy monitoring. A “LOW BATTERY” warning will show when battery power drops to the voltage value shown in the BATTERY ALARM screen as described on page 12.
WARNING! Never operate an R/C model with weakTx batteries! Reduced operational range and/or possible loss of control of the aircraft could result. Never mix used and new alkaline batteries. Replace weak alkaline batteries, or re-charge NiCd or NiMH batteries before attempting a flight!
A “Tx Batt.” timer in the TIMER menu described on page 28 can track the total amount of time the transmitter has been operational.
See the ACCESSORIES section on page 44 for optional batteries and chargers available at local hobby retailers.
CHARGE JACK AND CHARGING
RECHARGEABLE BATTERIES
The charge jack should only be used for recharging optional NiCd or NiMH batteries (charger not included). Do not try to recharge alkaline batteries.
Charge adapter leads for Futaba® brand transmitters are compatible, with the center pin being positive polarity. The Tx power switch must be in the OFF position to recharge batteries. Do not charge batteries at greater than 1 amp.
Cycling of the Tx batteries can be accomplished through this 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!!
WARNING! Do not accidentally short circuit the terminals inside the charge jack, as this can cause permanent damage to the radio’s charge circuitry and battery and void the warranty.
POWER LED
The blue LED illuminates when the power switch is turned on and ample voltage is supplied by the battery. This LED will fl ash if battery voltage drops to the voltage set in the BATTERY ALARM setting described on page 12.
FLIGHT CONTROLS
Channels 1– 6 are fully proportional. Channels 5 and 6 can be controlled by a nonproportional switch or mixed to channels 1– 4 for full proportional control.
Aircraft control is accomplished through various electro-mechanical devices which are manipulated by the pilot, such as the control sticks and toggle switches. In addition, the Tx can automatically manipulate the pilot’s control inputs electronically to alter the control
6 |
signals before they are delivered to the receiver (e.g. mixing two channels, applying |
|
differential reduction to a channel, etc.). Some electronic functions can be turned on/off by the pilot during fl ight such as a timer. Other functions should only be altered while the model is on the ground, such as changing travel limits or reversing for a particular channel.
GIMBAL STICKS
Ball-bearing construction allows both sticks to provide the ultimate in smooth, precise control. Stick length can be adjusted for optimum feel and control. Each stick consists of a base and a tip. To adjust, hold the base tightly, then loosen the tip by turning it counter-clockwise. Adjust the stick tip to the desired length. Tighten the stick by holding the tip in place and turning the base counter-clockwise until it’s tight against the tip.
STICK TENSION AND
THROTTLE RATCHET
Each control stick can be adjusted for softer or stiffer movement tension. A ratchet is also included for the throttle stick which can be adjusted for feel depending on personal preference. Adjustment of either feature requires removal of the rear of the Tx case as explained in the CASE SEPARATION AND ASSEMBLY section below.
CASE SEPARATION AND ASSEMBLY
WARNING! Failure to follow these instructions for separating and re-assembling the Tx case can result in permanent damage to the transmitter, and void the warranty. Contact Hobby Services if you do not feel comfortable that you can safely and accurately perform these steps.
ALWAYS disconnect and remove the batteries from the battery compartment FIRST. Failure to do so can result in permanent damage to the Tx.
Remove the six screws from the back of the Tx case. Carefully pull the case rear away from the case front and note exactly how all wires are routed inside the case.
After adjustments are made as described in other sections of this manual, close the case by fi rst carefully tucking all cables back inside as when the case was opened. Align the case rear back onto the case front, making sure that no wires are pinched between the case parts. Press the case halves together. Insert the screws back into their positions and carefully tighten them until snug - making sure not to cross the threads or over-tighten the screws. Re-connect the battery holder’s connector to the socket inside the Tx. Insert the battery into the compartment, and carefully tuck the wires inside the cavity so they do not become pinched when the door is closed. Close the battery door.

●StickTension: Silver screws on the back of each gimbal are used to adjust the stick tension, as shown at left. Turn the screw clockwise to make stick tension more fi rm. Turn the screw counter-clockwise to make stick tension more light.
●Throttle Ratchet: A silver ratchet bar is mounted across the throttle gimbal. For airplane use, a more firm ratchet feel might be desired for the throttle. In this case, turn the adjustment screw clockwise. For helicopter use, less of a ratchet feel might be desired. Turn this adjustment screw counter-clockwise to achieve the desired feel.
DIGITAL STICK TRIMS
The trim controls for the four main channels are digital. Holding the trim lever will cause the servo output to move repeatedly. Trim positions are visible on the LCD’s home screen, and stored into that respective memory. Changing the model memory will also cause trim settings to change accordingly.
For aircraft with glow engines, the precise position of the trim lever is helpful when determining the engine’s preferred idle point. When the main throttle stick is above 50% full throttle, it will not be possible to trim the throtle servo – even though the indicator on the LCD will move.
The amount of servo movement for each increment of a digital trim can be adjusted as desired, as explained in the TRIM SETTING section on page 18.
TOGGLE SWITCHES
Each switch can be assigned to control one of a variety of functions as desired and described throughout this manual. See page 4 for the location of all switches, which are also marked on the Tx by letter. The factory default switch assignments are as follows:

In addition to programming changes, stick mode changes require reversal of the throttle ratchet and elevator arm/spring. Refer to the CASE SEPARATION AND ASSEMBLY section on page 7 for opening and safely re-assembling the case after the mechanical adjustments are made. Failure to do this properly can cause permanent damage to the radio and void the warranty.
Throttle Ratchet: The long metal bar resting across the throttle gimbal must be moved to the other gimbal. Carefully remove the screws at each end of the bar. Re-locate the bar to the other gimbal and install across the ratcheted surface of the gimbal. Re-install both screws. Carefully install the screw at top until snug – do not over-tighten! The screw at bottom should be tightened until the vertical movement of this stick has the
desired amount of resistance. |

|
Elevator arm and spring: The black plastic arm and spring must be re-located from the elevator gimbal to the opposite gimbal. Using a pair of needle nose pliers or hemostats, carefully grip the end of the spring which is looped over the end of the black plastic arm and gently lift it off the arm. Then slide the spring towards the center of the gimbal to remove it from the gimbal. Set the spring aside.
Raise the plastic arm to a vertical position. Slide the arm towards the center of the gimbal to remove it from its mounting pin.
Rotate the arm 180 degrees to mount it to the opposite gimbal.While in the vertical position, slide the arm over the mounting pin on the opposite gimbal. Lay the arm down across the gimbal.
Gripping one loop on the end of the spring with pliers or hemostat, carefully lower the opposite loop of the spring into the gimbal to slide it over the appropriate mounting pin. With the spring holding onto the pin inside the gimbal, carefully stretch the spring and hook the loop over the end of the plastic arm. Confi rm the arm and spring are mounted properly by moving this stick and ensuring all movement is smooth but with resistance from the spring.
Close the transmitter as explained in the CASE SEPARATION AND ASSEMBLY section.
CONTRAST
Adjust the LCD’s contrast level for optimum viewing.
BEEP VOLUME
Adjust the loudness of the radio’s beeper as desired. This volume setting affects all tones that are emitted from the radio including while making adjustments such as trim adjustments, programming changes, etc. Beep volume for all alarms is not adjustable.
BATTERY ALARM
An alarm will sound and the display will show “LOW BATTERY” when the Tx battery’s voltage drops to the level shown in this setting. Do NOT set this value too low, as the radio could lose power very rapidly as the battery nears full discharge and cause a loss of control of the model. Land the model immediately once this alarm has sounded!

FLAP SETTINGS
The “FLAP” setting allows for confi guration of the ailerons and/or fl aps of the airplane. Move the cursor over “1AI” to select from the following options:
1AI: Use this “1 aileron” setting for normal wing types having one aileron on each wing, where by utilizing a Y-harness one servo input controls the movements of both servos simultaneously.
1AI1FL: This “1 aileron + 1 flap” setting is for wings having one servo that controls the ailerons on both wings, and another servo (or 2 servos on a Y-harness) that controls the fl aps on both wings (both servos moving in the same direction). Connect the aileron servo to Rx channel 1, and the flap servo to channel 5. (Not available for delta.)
2AI: This “2 ailerons” setting is for airplanes having one aileron servo for each wing. Connect one aileron servo to Rx channel 1, and the other to channel 6. This setting allows each aileron servo to function independently of the other.
2AI1FL: This “2 ailerons + 1 fl ap” setting is for airplanes having two separate aileron servos, requiring one servo to control each aileron, and also one servo (or 2 servos on a Y-harness) that will control fl aps for both wings simultaneously. (Not available for 2 elev tail settings.)
TAIL SETTINGS
“Normal” is the factory default setting for the “TAIL” type. Move the cursor over “Normal”, press ENTER then
