Here is my 2 cents worth. Go ahaead and buy it. I would think about ending the reciever in to be checked. Just checking it shouldn't cost more than 20 bucks. Or just go ahaead and buy a new Hitec reciever. The new one will cost about 60 bucks with chrystal and S&H. If you finally end up with a computer radio you will already have at least one spare reciever. Anyhow a test can be done with an electric engraver with a pencil eraser attatched. Use the engraver to vibrate the case of the reciever. And check the servo's (which are hooked up and powered up) for jitters or random movements. These are sighns of reciever damage. You should also check the switch. They can be damaged as well. Bottom line ya pays your money and ya takes your chances. I feel you should be ok with this used radio.
