Reply to "Electrical question on the Menard 3.5 Beta and the fast start- could wiring the motors in series fix this?"

With the parallel to series conversion originally discussed here and demonstrated by @hokie71 (thank you for the proof of concept and great job!), the electrical load of the motors on the motor driver board has been divided by 4 from the original configuration.

Now I have a question ? do you think A second unit can be linked  via a tether  so both units 4 motors can be run off of  1 receiver board?

In theory this new proposed arrangement should work with each pair of motors wired in series and each series pair wired together in parallel across the driver outputs.

In this dual loco MU arrangement, the combined electrical motor load on a single motor driver board's output would be half that of the factory motor wiring configuration.

I would speculate that with this alternate series/parallel arrangement, that the relative speed of the consist may increase somewhat over the first series wiring modification discussed above, but still be slower than stock.
