I have a new 7C 2.4 radio and would like to know how to change the snaps,ECT,right pos,
right neg, left neg, left pos,The radio is set with + for all 3 ch,How do you get it to minus,
Thanks Bob

You actually want four snap roll mixes. The Futaba 7C has the capability to set only one. You cannot set up snap roll mixes for left and right, positive and negative snaps. Pick only one. Other types of snaps will have to be done in the conventional manner: move the sticks as necessary to get the snap in the desired direction.

To change the numbers from positive to negative, you will just rotate the dial to set the number you desire.

If you want more snap roll mixes, you need "more" transmitter. The Futaba 10C is the "smallest" transmitter that will have the four snap roll options. Of course, the 12 FG, 12 Z, and 14 MZ also can do this.

Thanks for your reply but this dosen't answer my question.I know I can only have one set at a time, On page 47 of the manual it shows the settings for 4 types of snaps,My question was meant to be how do I get the TX in to the minus position,Rotating the Dial as you suggested
dosen't get you in to the minus setting,
Thanks again
Bob
