Let me guess; does the adder-subtractor design produce slow changes in direction while the motor-for-each-track design only makes quick (...) (20 years ago, 14-Apr-05, to lugnet.technic)

| | | | (...) Well sort of. The application of torque is reversed - when steering a "1 motor per track" model, you only get 1 motor driving, when going straight you get 2. This is simply reversed in the adder/subtractor system. It's a small price to pay for (...) (20 years ago, 15-Apr-05, to lugnet.technic)
