I think you are drawing entirely the wrong conclusions. As others have
said, your mechanical connection is at fault, not the differences between
motors. Two motors are better than one. Period. (assuming they are going
in the same direction ;-) They do not interfere with each other.
The scientific test is to tach each motor separately, then tach them
together, driving the same load in all cases.

| After the good suggestions from folks (see the Balancing Bots thread) I did some experiments with using 2 motors to drive one axle (to double the power to the axle) and thought the results might be of interest to others. I first tried having the (...) (25 years ago, 7-Jan-00, to lugnet.robotics)
