Was at the flying field and could not switch transmitter from one model to another. I would get the Model Select screen but when I tried to change models it would jump back to the main screen (the screen with the trim tabs/timer on it) Must have tried it 10 times then it worked. Flew and tried to change it back to the original model and it would not change. Came home now it's working fine. Transmitter is five or more years old, never had any problems until this. Battery was fully charged. Been flying OK with it for the last couple of weeks. Until today.
Anybody heard of this? And better yet, found a fix?

Thanks
Bob
