2.4GHz 6-CHANNEL COMPUTER RADIO 
INSTRUCTION MANUAL 

 
Tactic's TTX650 computer transmitter uses the advanced 2.4GHz spread spectrum SLT "Secure Link Technology" 
protocol for solid, interference-free control of R/C models.  Ball-bearing gimbals, a wireless trainer system, 20 
model memories, and advanced programming options are just a few of the benefits which can be used on models 
of all sizes.  Tactic 2.4GHz transmitters are compatible only with Tactic brand receivers and those utilizing the SLT 
protocol. 

 

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 modification will void your warranty.
