I won’t keep y’all wondering this time.
How about this for a small ESC?
Combined DSM2 RX and 3 amp ESC.
Works with any DSM2 TX.
Centre off control.
Directional lights.
One sound trigger.
3 - 18 volts.
Just finished testing one and it works just fine.
Going to be great for the Thomas and L’il Big Hauler locos and any small Large Scale locos where lack of space is a problem.
Battery powered 0n-30" anyone?
Smaller ESC’s available, down to N scale.
24 volt 6 amp version coming. (Hopefully)
Amazing!
All thanks to the robotics hobby.
R2D2 did this? Cool.
I Know that this is a battery thingie, and I’m track powered.
So, I can’t decipher even upside down, “Combined DSM2 RX and 3 amp ESC.”
Somebody help out this old fool… I’m guessing that this is a battery powered systems equilivent of a decoder for a DCC system on radio throttles. ??
Lets see if C3PO can translate this for you…
DSM2 - A common method of Radio Communication in the model industry Digital Spread spectruM Version2. Explaining DSM technology is a little too complicated for this forum - Google it if you are interested in more.
RX is shorthand for Receiver
ESC is an Electronic Speed Control
This unit combines a Receiver using Digital Spread Spectrum technology with an Electronic Speed Control that will handle up to 3 Amps.
Clear as mud now?
Mock all you like boyos.
Google hobby robotics and open your minds.
I presume y’all know how to Google. Well, maybe not Rooster.
The innovations coming out of that hobby are mind boggling.
Thanks for the explanation Jon. It is spot on.
Sooooooo If I have the right TX unit to match, then I could put one of these units in a track powered engine drawing less then 3 Amps, and control it with the remote TX unit. Correct?
If so. wow the possibilities !

And Tony’s new TX-20 handheld is just perfect for controlling it. But note the track power will have to be full-on at all times, so the RX/ESC can decide how much power to give the motor. It precludes anything else being on the track unless it also has an ESC.
But batteries onboard the engine make lots and lots of sense. You can run it anywhere, without worrying about the dirt or other people on the track - they can even use track power control as you will be isolated. (Back in the old days, before RGSEast switched entirely to battery, I had the only battery-r/c loco around. I could go anywhere on the track, ignoring the other users. They were restricted to one engine on the track at a time.)
OK… Would this handle the track voltage of a G- DCC system? Ie: using this instead of a standard decoder? Like to run some mine equipment off of spurs or in the mine area, and not use the DCC throttle? Or just wire the mine with a constant 12VDC supply with out a controller on the power?
This new ESC was designed by Deltang specifically for battery power only.
By adding a suitable bridge rectifier with filtering caps it can be used with constant track power.
You would need to limit the track voltage to a maximum of 18 volts after the bridge rectifier and any filtering capacitors.
They are not as sophisticated as DCC decoders, but they have no need to be.
Battery power on board ESC’s are not new. I have been making them since 1988 and have sold thousands of them.
I don’t want to start a battery - v - track powered war but those track powered users who switch to the “Dark Side”, as some wags put it, almost never go back to track power.
What is different about this one is the small size with the volts and amp power handling characteristics.
Together with modern Li-xx based batteries other models of this ESC are made small enough for battery powered “N” scale.
One myth about RCS battery R/C has been that you had to have one TX for each loco. That was definitely not true and remains not true. You can bind as many RX’s (locos) as you wish to one TX and you can swap the RX’s (locos) between TX’s.
There will likely be another variation of the TX20 that can control up to 12 locos independently at the same time and swap between locos at will.

I know Tony…I’m currently working on two of me!
If you are successful at duplication that at least gives us two targets to ridicule. 
LOL…

Dammit Tony… Like I need more bad ideas???
Heheheheh!!!
Just send money.
