I have been experimenting with Sariel's Studless Transverse Subtractor from pages 291 and 292 of his book. It went together really easily, very straight forward design. I am using two (2) M motors like in his design. My observations: 1. When I turn on the motor connected to the differential connected to the 6 l axels (the normal output of the Subtractor) I can make the outputs go forward or reverse. 2. When I turn on the other motor the outputs are reverse of each other. 3. When I turn on both motors (both forward or both reverse) only one output is driven. 4. When I turn on both motors and select one forward and the other reverse, the other output is driven. I have changed the motors to account for one motor being stronger tha the other and I get the same results. I just want to make sure that this behavior is normal before I continue. If it is, great! I can use this, if not I want to correct it before I continue. Overall I really like it, it is a compact and useful design! Thanks, Andy D
