This is just an idea. Don't modify any of the programs that are already in the radio. That way you always have a good program stored in the radio. Start with a new model. Make your own program. Because some day you will need that skill. If the new program is bad, you can always delete it. Do a search in YouTube an look for Edge TX. Look for a guy name Painless 360. He has some good videos. I'll see if I can find something on my end. Good luck.
