I think you will need to upgrade to something more powerful very soon, specially if you are designing the drive train to use brakes for steering. I am intrigued by your design but worried at the same time. In any cases, we will see what will happen and that makes your build interesting.
Yeah, I looked at the mount and the motor and thought the same thing. When I scratch build tanks, there tends to be a lot of re-engineering since things don't tend to work out the way I see them in my head as I am not a mechanical engineer. I do end up getting them to work though one way or another...
Having broken motor mounts in my tanks due to the torsional stresses of the motors, I have learned to overbuild everything as the forces of motion in tanks tend to be quite large.
All of my scratch built tanks have ended up with a dual motor setup as it is the simplest method of control of the two tracks. I do understand that you are trying to make this tank act like the real thing which is why you chose the "breaking one track" method. I have found that it can be done with electronic methods, but it doesn't 100% percent replicate the motion of using a brake on one track. I do hope you can get it worked out as it will be a cool build.
