The TTX403 offers more versatility than you'd expect from a transmitter this small. It's ideal for flying all Flyzone and Great Planes micros and has the range to make it reliable for use with bigger birds too. That's in addition to exclusive Secure Link Technology, in which an unbreakable link is created between the transmitter and the companion SLT receiver – a link that virtually eliminates outside interference. You get all this and more in a compact transmitter that's packed with features at an affordable price.
