I don't know what it is about my transmitter, but when I go to progam say program mix 2 and I do an Aux 3 to Aux 3 mix and then I go and set it to activate by snap roll button and then I make sure I'm on master/norm and then I go to the percentage travel page of the mix and hit the snap roll button, the "pos" shown as 0 / 1 when I hit the snap roll button does not change.

But if I set it to work of the flap switch, it does change the "pos" from 0 to 1 back and forth just fine.

From the information above can anyone tell me why this does not work? When I do the aux 3 mix deal am I supposed to activate or inhibit the snap roll function? I activated it and set the snap roll percentages all to 0 and I did the opposite as well.

I have had this problem for years and have no idea how to make it to where it works right.

Thanks in advance for any assistance.

Tom: I have followed your instructions to a T that you gave me last year and it's just not working. I even put a servo on Aux three so I could see things happening instead of an electronic valve and I'm having no luck with this switch position change when hitting the button.
