I was at the DelTang site again and found the answer about speed steps, at least for DelTang.

They do use speed steps (which makes sense since it is PWM),
but it is 256 steps in each direction.

So twice as fine a control as the best you can get with DCC,
and about nine times finer than the 28 steps offered with S-Cab.

This is all theoretical as I have never had a problem controlling the speed with DCC.
But it is nice to know that using BPRC with an ESC can give equal or better speed control.



Some more information about DelTang speed steps, there are 256 but you can't select an individual step.

In effect the throttle approximates a smooth DC throttle.

In addition you can change the low and high voltages expressed as a percentage.

Some programming is needed for this, but straightforward once you master the art!
