I'm thinking of making a RC tank that should be simple as possible. But I'm not sure how to make proper steering for the tank. I googled about tank steering and found (for me) complex solutions as dual differential steering.
Now, my question is - Is it possible to steere the tank with momentum?
Idea for project is - Left motor will power left Wheele(tracks are too complicated to design), right motor will power right Wheele. Powered Wheele are at the back. So if I want to steere the tank to the left side, right motor will be on, left will be off. Does this method Works? Should right motor go forward but left go backward?

Here is the sketch. This is sketch for rotating/steering from place.
I guess it will work fine, but what if tank moves forward/backward and wants to steere?
