Hi Soaring High
what field are you at? I see you are in Abingdon. I fly at Swan Harbor. I still have a DX6i which is fine. The DX7S came out a few years ago and half my planes are on it. The original DX7 was JR based, but a few people still have them. If the TX has not been sitting in high heat, it should be ok. I would just change the battery. Come on out to Swan Harbor
