| It depends...
The battery, ESC and motor all need to be rated for the power need to make the model fly in the style you fly. If you have a motor that can stand (say) 30A, but you use it in a small heli where even at maximum pitch you only draw 25A then all you'll need is a 25A ESC (even though you have a 30A motor).
If your motor is over rated for the model, then you'll probably be running at below optimum efficiency (specifically the "iron losses" or "no load current" of the motor is probably going to be higher than it needs to be, and probably the weight too). This will show up as reduced run times.
12 amps is quite a low figure. If you're talking about a Hornet or Hummingbird (or their clones) you're probably OK if you dont want a "hot" 3D setup, but even my Shogun can draw over 25A at times.
The most likely consequence of pushing an ESC too hard is a burned out ESC (and this can be quite literal in the "burned" part).
