Rick,

Thank you.
I really like everything I read about DelTang and DavidT's input in the forums has been very enlightening.

Since I plan to cab mount the gear in the Porter there isn't much room,
but I figure that with the All-Season Banta cab I should be able to fit it all in.
It seems the DelTang equipment is smaller which is also a big plus for it.

I didn't realize it when I wrote my first post but I guess I have a pretty basic question on ESC versus DCC-connected.
With S-Cab, the receiver connects to a small set of standard DCC receivers and operates in 28 speed step mode.
You can also adjust the min/max voltage percentage as a poor-man's speed curve.

One thing I do like about the DCC connected approach, if I understand it correctly,
is that the transmitter talks to all receivers but the command includes a 2-digit DCC address so only the specified engine responds.
That implies that the S-Cab is actually encoding a sub-set of regular DCC commands in its signal.
Not sure if that is a good thing or not as DCC was really developed to solve a different problem
(encoding digital commands on a power signal). 

With a standard proportional ESC I know it is still using PWM,
but is it using something equivalent to speed steps or is it approximating linear control?
I'm pretty sure I've read that, at least with DelTang, you can also adjust starting voltage.
