setting up a 7 ch airplane with dual aileron,flap

You should read the manual first and try to understand how deviation works. If you have worked through the manual most aspects will be clear.
To control two output channels with one stick you simply choose the same stick as input for both channels (or one inverted or scaled or with offset... the possibilities are great).
