The ™ TTX660 radio can store up to 30 models in memory, making it perfect to control a full fleet of models with the super-affordable Tactic brand 2.4GHz receivers.
of the wires before disconnecting the plug from the Tx. Install the NiCd or NiMH battery by first 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.
channels, applying differential reduction to a channel, etc.). Some electronic functions can be turned on/off by the pilot during flight 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.
● Stick Tension: 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 firm. 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.

Two servos are used in the tail – one for each control surface, with connections as shown in the graphic above.
CHANNEL ASSIGNMENTS This function allows transmitter channels to be re-assigned to different channels before being sent to the receiver. This can be useful for models having unusual configurations or inaccessible receivers. Some small electric flight models use only elevator, throttle, and rudder channels (not aileron). Here, it’s often preferred that the rudder be controlled with the opposite stick (right stick for Mode 2 configurations). Such channel re-assignment can be done in this screen.
TRAINER TRAINER SLV MST 1 2 CTRL:SF 3 4 5 6 The process of linking transmitters for training purposes is explained on page 37. When in training mode with the TTX660 being used by the teacher, this radio can allow the teacher to transfer control of all or only certain channels to the student if desired. Enter this screen. Press or to select a channel to set. Press ENTER to toggle the setting. Repeat with other channels as desired.
Sub-trim: Finely adjusts a channel’s center position. Be aware that extreme adjustments of sub-trim could possibly result in servo binding if the servo’s output arm moves too far in the model. This is available for all channels. Travel limits: Sets the maximum travel limits for each channel. Limits can be set for each side of center. If two channels are mixed, adjusting the travel limits of each individual channel may be necessary to adjust the travel limits for the entire mix.
Moving the control stick for the channel shown on-screen will change the position of the vertical line in the graph. The point where the vertical line intersects the diagonal line is shown at the bottom-left on the screen. The “x” (horizontal) coordinate is on the left, and “y” (vertical) coordinate is on the right. Repeat the above steps for the aileron, elevator, and rudder channels as desired.
Travel: To adjust the travel limits for a selected channel, deflect the switch to one position and adjust the maximum travel limit for this switch position, and then repeat for the opposite switch position. Highlight either and press CLEAR to change back to the default setting. Press ENTER when finished. While the output channel is being operated normally, any movement of the input channel will be mixed to – and also affect the movement of – the output channel.

RF OUTPUT RF OUTPUT RF ON/OFF: ON The RF output signal can be turned on or off. If changing any programming parameters in the radio it’s recommended to turn the RF off to conserve radio power. Leave the RF output signal ON anytime the model is being controlled. Enter this screen to perform a range check on the radio system, as fully explained on page 39. RANGE TEST:99sec TIMER 01 > 5.
The “START/STOP” screen should show. Moving the stick up or down will show changes to the “THROTTLE” position value. The “START/STOP” value shows the trip point where starting and stopping the timer will occur. Move the stick to the desired position for the timer’s trip point and press ENTER. The position value for START/STOP should now match that for THROTTLE. Press ESC to return the timer setting screen. The throttle stick’s START/STOP position for the timer should show below the timer settings.
SWASH TYPE 1 Servo SWASH TYPE 2Sv(180) 1 Servo: Tilting of the swash plate is accomplished with one servo for control of the elevator axis and one servo for the aileron axis. Another servo directly controls collective pitch. Selecting this swash type means that no swash plate mixers are required or used. This is typically used for flybarless systems. 2Sv(180): For CCPM with servos (aileron and pitch) connected to the swash plate (180 degrees apart).
if using a helicopter which has CCPM mixing, read the SWASH TYPE section on the previous page before adjusting the reversing and travel limits settings. THROTTLE CUT Allows the throttle channel’s output to be quickly moved to a user-defined position by flipping a switch. This is to reduce engine / motor power for safety reasons. When setting up the model mechanically, make sure the carburetor is at full-open when the throttle stick is at full position. Use the trim to adjust the engine idle position.
To select a switch to turn throttle hold on or off during flight, set the Control field to ON. With the cursor next to CTRL, deflect the switch that will control throttle hold. In one position the control will be ON. Moving the switch to the opposition will turn the control OFF. Move the cursor next to “Position” and set a percent of full throttle that the throttle channel will deflect to automatically when the control switch is moved to the ON position.
To set points on the curve, start at the minimum throttle position which will be noted as point “L”. A point for “L” is not marked on the graph, but is the left-most end of the curve line. The vertical position of this point can be adjusted by moving the cursor to the RATE percentage, pressing ENTER and then or as desired. Press ENTER when finished. To set point 1 on the graph, advance the throttle stick until * shows next to “Point”. Find the desired throttle stick position and press ENTER.
GYRO MIXER This function is for setting and adjusting the sensitivity of an optional tail gyro. Enter this screen. Normal Switch Control GYRO MIXING NORM: 0% GYRO MIXING SP.0: 0% SP.1: 0% SP.2: 0% CTRL:----- CTRL:SE(2) To make the gyro mixing active at all times do NOT assign a switch at the CTRL line.

4. Release the “LINK” or “BIND” button. 5. If the linking is successful, the Rx LED will flash once and then remain ON. 6. Test for proper Tx/Rx functionality before use. If the radio doesn’t appear to have become properly linked, repeat steps 1–6 above and move the Tx at least three feet away from the Rx. FAILSAFE FUNCTION The failsafe function is not controlled by the TTX660 transmitter itself, but rather by the Tactic receiver. Tactic’s stand-alone 2.
IMPORTANT! Before flying the model in training situations it’s very important to make sure all channel reverse settings and trim adjustments on the teacher and student transmitters match! Otherwise, the model could suddenly veer in an unwanted manner when the teacher’s trainer switch is activated. Proper matching of the student and teacher’s Tx settings should ensure that no unexpected movements occur when the trainer switch is pressed.
3. Move the student’s transmitter to within 3 feet of the teacher’s transmitter, turn the power switch on and set the RF OUTPUT to ON. 4. The TTX410/610 LED should flash three times and then stay on to indicate the bind was complete. Release the trainer switch. 5. Once linked, move the throttle stick on both transmitters to minimum. Turn the Rx power on and make sure only those channels selected for transfer to the student are transferred when the TTX660 trainer switch is deflected.
3. Move the cursor over “99sec”. This time determines how long before the radio’s output power automatically returns to full power. 4. Place the Rx/model on the ground and apply power to the Rx/model. 5. Hold the Tx as it will be held during flight and press ENTER. The range test timer on-screen will start to count down. Tones will sound to identify that this function is active. 6. Move the Tx 100 feet away from the model and confirm all controls are transferred smoothly at all times.
easily becoming dislodged during normal flight. It’s best to check the system with the propeller removed from the aircraft. 1. Once all connections are made, check the general operation of the radio and all other components before attempting a flight. 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 reverse setting for that channel. 5.
4. During the first flight, it might be necessary to re-trim the main channels to allow the model to sustain smooth, even flight. If further adjustments are required on the ground, make sure to turn off the engine or ESC/motor beforehand. 5. When the flight is completed, remove power from the system as described before. Shut down power to the electronic speed control or glow engine first, then the receiver, and finally the transmitter.
