The T4B is made of strong plastic. It doesn't feel cheap. It has only the controls you need for a basic 4 channel transmitter. Servo reversal is an issue, sometimes, and there is a dedicated switch for each servo. There is a receiver sync button, and a "trainer" socket. There is an on-off switch. That's it. No software, not other buttons or knobs. This is your basic 4 channel receiver.
I'm a lefty, and switching to left hand operation was easy, as long as reasonable caution, and a good pair of needlenose pliers is used. A lever and a spring.
The one drawback to this system is poor documentation. It is not a real problem, if you have some experience, but I could see how a newbie could come to grief over it. The manufacturer's website was translated from Chinese by a high school student, and requires real patience to decipher. Filling out a "Support Request" for each question is cumbersome, too. But, you get past all that.
Back in the seventies, I had a Futaba 4 channel beginner's outfit. This is better. The Futaba transmitter back then was fragile.
I coupled this with the FS-R6B receiver and ES-3001 servos. This will control a 69" powered glider.
Range check started glitching at about 600 ft. This was with 4 nicads in a battery pack on the receiver. At 600 ft, you really need to start bringing your plane back toward you, anyway, to keep oriented, unless you are flying in New Mexico in the desert. (grin) 600 ft range will do just fine for me.
I'll be ordering a second receiver and set of servos as soon as they become available here. VH's prices rock!
I purchased the transmitter and receiver thinking that it would fly my delta plane as it said in the advertisement but it has no "V" tail mixing. Otherwise this is a great transmitter for the cost . Range tests show it to be responsive, binding is instantaneous unlike some of the other transmitters with DSM technology (I've had a throttle turn on by itself with other club members verifying the problem was the receiver). If finances are a grave concern, buy this transmitter for 4 channel operation if you need just a basic transmitter without any frills. (Posted on 4/12/2013)
This is a very easy to use radio. Unlike the 6 channel radios by FlySky, this one does not require a computer to program it. Only dislike is it does not have a V-Tail mixing switch but is advertised with one. It will not work with flying wings. Please change the description. (Posted on 2/10/2013)
