I've had my Turnigy radio for over 3 years. It wasn't easy to get one, because they were having problems keeping enough in stock. I don't know if that was due to slow manufacturing, or what ever the reason for that.  I have had absolutely no problems with it. The gimbals are not sloppy, the servo respone is not jittery, I have never experienced a "BROWNOUT", nor have any of my rx's ever required re-binding. No switches have broken off. <div> As far as I am concerned, there is no "upgrade" radio for me. Only other radios that cost more, and will not give me more than I already have. Just because it cost me less to purchase, doesn't make it less capable, or not as good as a "Name Brand" radio. I'm going to go way out on a limb here, and suggest that some of the detractors may be jealous, or feeling a bit put out because they spent so much on their radios, and got so little for their dollars. Would I fly a $3,000.00 airplane with this radio? YOU BET!!!! My $100.00 airplanes mean just as much to me as a more expensive one would. </div>
