: Yes, we hooked both drill motors to the same voltage source and used an oscilliscope to count the RPMs. So, we know it is not the speed controllers.

I'm intrigued... How do you measure the motor RPMs with an oscilloscope?

As for using software to compensate: the only way I can think of doing
this is using te yaw rate sensor. Between the resolution of the sensor
and the limitations of the control system, I'm not sure if you'll be able
to achieve an acceptable level of control, though.
