I'll start by saying that I just scrolled through the classifieds here, and saw several JR, Futaba, Airtronics, and Spektrum radios for sale. Not one single ad for a Turnigy 9x. That speaks volumes to me. When I was early into r/c, I purchased an old FM Futaba 6EXA. But I quickly found it wouldn't fill my needs with only 3 model memories in it. So I did some research, and bought the best radio I could afford. It had to have certain attributes. It had to be 2.4 Ghz, so I wouldn't interfere with any others at the field, nor would they interfere with me. It also would have to be a radio I could grow with. More channels, more model memories. It would have to be well built. And it had to use rx's that were inexpensive, yet perform well. The Turnigy 9x filled all those requirements, and more. Range checked to slightly over 1-1/2 miles, on the ground, with trees, hills, and buildings in the way. I used a philips screwdriver, installed my own smartieparts board and backlight, which also gave me a usb connector, and now I have access to other firmware for free. Now my Tx has unlimited mixes, 16  model memories, assignable switches and pots. I can use it for any aircraft. Airplanes, Heli's, and Gliders. I can store programs on my pc, and upload them just before going to the field, or, take my laptop and do it there, if I should exeed 16 models. My Rx's cost average 12bucks for8 ch, 11 bucks for 6ch. My total cost? About $150.00. I don't see any need for any other radios in my hangar...Oh, if I should find a need to fly someone else's plane that has one of those "other" rx's in it, I can simply switch to that brand of Module, and fly it.
