Devo 7e Tank Control

hi i have a devo 7e with deviation firmware i have been playing with mixer setting for a twin motor tank style control for a robot with no luck just need a push in the right direction
i need to be able to control 2 motors on one stick to control forward back left and right what mixer config should i use?

thanks in advance

Can you talk about how the default Tx does stuff ? Maybe that will help.
To control 2 motors on a stick you could use 2 channels and set the input to the same thing
So for example if channel 1 controlled one motor and channel 2 the other
you could go into the mixer and set the source for channel 1 as say throttle and the same for channel 2
Hope this helps.

most rc tanks use 2 sticks, one for each track

ok i have a robot to compete in ant weight robot wars it is driven by 2 wheels both with independent motors and controllers i would like it to be in mode 2 with throttle controlling forward and rudder controlling left and right motion leaving the other stick for weapons

I think a mix similar to elevon mixing for delta wing would work. Search the model config for some examples.

Edit. Attached combat wing config file
