Thanks for the help guys I appreciate it. I assume I must be using an AM radio, it's at least 15 years old. I do have two of them and both do the same thing. So if I switch between Lipo and NiMh then I will need to connect to a computer to make the change in settings? Can you guys recommend me an inexpensive radio and would I need to replace my reciever as well for it to work with a newer FM style radio?
