TACTIC TTX404 2.4GHZ
4-CHANNEL SPREAD SPECTRUM 
RADIO INSTRUCTIONS
The Tactic TTX404 airplane radio system uses an advanced 
2.4GHz spread spectrum technology to prevent unwanted 
outside interference from interrupting control of the model, 
ensuring error-free fl ying and eliminating the need to pull 
frequency pins before every fl ight. Tactic 2.4GHz transmitters 
and receivers are not compatible with other brands of 
2.4GHz equipment.
For safe operation and best results, it’s strongly 
recommended to read this manual in its entirety 
before use! Also read and understand the 
instructions included with the model. Damage resulting 
from misuse or modifi cation will void your warranty.

TTX404 TRANSMITTER (Tx)
The TTX404 airplane transmitter is available in either a “Mode 
2” confi guration with throttle on the left and elevator on the 
right, or “Mode 1” confi guration with throttle on the right and 
elevator on the left. Mode 2 radios are most commonly used 
in the U.S., whereas Mode 1 radios are popular in other 
countries. Be sure the radio purchased is of the correct mode.
Four “AA” batteries are required to power the Tx (not included). 
Non-rechargeable 1.5V alkaline, or 1.2V rechargeable nickel-
cadmium (NiCd) or nickel-metal hydride (NiMH) cells, can be 
used. Do not mix cell types, or old and new cells, etc. See 
the SERVOS AND ACCESSORIES section on page 16 for 
optional batteries available at local hobby retailers.
To install the batteries, slide the battery door down. Insert the 
cells as shown in the diagram, making sure to note proper 
polarity for each cell. Close the battery door.
POWER SWITCH, LED, and LOW BATTERY ALARM
The red 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.
