There's a lot to be said for the simple things in life, and with RC equipment becoming ever more flexible it's a refreshing change to find a simple, 4 channel radio that dispenses with the need for programming before you can use it.
The Turnigy TGY-i4X AFHDS/2A does exactly that and is a great entry level 4-channel telemetry 2.4ghz transmitter that can be switched between 1st and 2nd generation Automatic Frequency Hopping Digital System (AFHDS 2A) spread spectrum technology. The Turnigy TGY-i4X has a nice quality look and feel, while the programming is limited to one-switch V-tail/elevon mixing and servo reversing only. The transmitter is capable of being upgraded to up to 10 channels, see manual for details.
An ergonomically designed, ultra slim case design fits comfortably in your hands, an advantage during long flights. Digital trims and easy to read battery indicator LEDs give the TGY-i4X a modern feel with all the essential features you need. With a low profile antenna, the TGY-i4X is easy to transport and store. Adjustable length sticks, and a loop for attaching a neck strap round out the list of comfort features this radio offers.
The TGY-i4X comes with the TGY-i4X 4-channel receiver and is a superb budget radio for both new and experienced pilots alike!

I am pleasantly pleased and surprised by the quality and functionality of this radio. The quality of the soldering, components, wiring, mainboard, gimbles, sticks, digital trim taps, and even the case ( which is the same size as the TGY-i6 ) are surprisingly good. I really didn't expect it for such a low price radio system but in all reality it is a very fine radio for the money. It's very similar in its specifications to the Turnigy TGY-i6 system except that this TGY-i4X is a non-computerized system, but expandable to 10-channels using switches and dial knobs. The TGY-i4X even has a good audible sound alarm warning which turns on if and when battery power drops below 4.2V.
I purchased the mode-1 version during the summer madness sale, since it was about 1 USD cheaper, but it was very easy to make the change to mode-2. I wanted a non-computerized radio so that I could make it 10-channels and have a retro-style system to fly once in awhile, for a change.
The package includes a 6-channel receive with bind connector plug, various extra face-plate stickers if you plan to upgrade the transmitter to 10-channels, and a well written user's manual booklet. This was definitely a good purchase for the money and even a better bargain during the summer madness sale event. I'm happy - thank you Hobby King !
