Sorry to be asking so many questions Peter. A fool can ask more questions than a wise man can answer. Have you tried storing your model setup in your computer and can you read the files to see what you have? For example I'd like to know what each switch is programmed to do. On a Futaba you can put more than one function on a switch and it is difficult to figure out what does what if you haven't used that model in a long time. Then the next question is, can you change the program on the computer and up/down load it to the transmitter? These would be great features to have.
