The problem comes from how the motors are constructed(not sure specifically, someone fill me in). Also, lower KV motors (17.5, etc) are harder to get rolling, and this is compounded by the super-tall gearing required for these motors.
There is no firmware that allowed sensored motors to work specifically work, just the newer firmware is a lot better, and so happens that mod - sensored motors work. the solution is that they are working on a new esc, and it will have a sensor port. No idea when it will be ready.
