TTX440
2.4GHz
Radio Control System
I N S T R U C T I O N
The Tactic TTX440 radio system uses 2.4GHz spread
spectrum technology. While you're fl ying, spread spectrum
automatically, rapidly and seamlessly changes between "open"
frequencies in the 2.4GHz band, so it never operates on the
same frequency long enough to receive interference. This
assures that your receiver will always be reading commands
from your transmitter only, eliminating errant signals which
can cause unwanted servo movement or loss of control. Tactic
2.4GHz transmitters and receivers are not compatible with other
brands of 2.4GHz equipment.
The Tactic TTX440 radio system replaces the
radio system originally included with your airplane.
Replace any instructions in the airplane manual
that refer to the radio control system with these
instructions.

Summary of Contents for Tactic TTX440

  • Page 1 Tactic 2.4GHz transmitters and receivers are not compatible with other brands of 2.4GHz equipment.
  • Page 2: Identification Of Controls

    IDENTIFICATION OF CONTROLS Take a minute to familiarize yourself with the transmitter’s controls. The transmitters in the illustrations for both 3 and 4-channel are the same, but the servos are connected to the receiver differently depending on whether or not your model has ailerons.
  • Page 3 Trim Levers – The trim levers are used to make small, in-fl ight adjustments to the assigned control surface’s neutral position. When fl ying, adjust the levers as necessary to “fi ne-tune” the model’s fl ight path so it will fl y straight- and-level when the control sticks are neutral (“hands-off”).
  • Page 4 ADUSTMENTS/FUNCTIONS Antenna Neck Strap Hook & channel On/Off Switch Servo Reversing Switches Power Indicator Antenna – The antenna pivots at the base and may be rotated downward for storage and transport. When fl ying, be certain the antenna is in the upright position for the strongest signal.
  • Page 5: Install The Batteries

    SET UP AND CHECK THE CONTROLS INSTALL THE BATTERIES 1. Remove the battery cover from the transmitter by pressing on the cover and sliding it downward. Install four new AA batteries. Then replace the cover. 2. Turn on the transmitter. All three LEDs (light-emitting diodes) should light. If any of the lights do not illuminate, battery power is low.

    2. Connect the battery to the ESC (or turn on the receiver switch if your model has one). With the throttle stick all the way down, move the control sticks (but don’t move the throttle stick, otherwise the propeller may turn). If the controls respond, the receiver is already bound and nothing else needs to be done.

    TROUBLESHOOTING The transmitter is on and the motor battery is connected, but the servos do not respond ● Be certain the motor battery and transmitter batteries are suffi ciently charged. ● The receiver may not be reading signals from the transmitter. Perform the binding operation as described on page 5.
