The last one (still partly in the paint shop) I have only recently opened again and discovered wiring for a BPRC system as well as the ESC left by the previous owner.
It's a Tamya esc TEU unit? I think it's a 2.4Ghz. Still need to get to mr fixer upper for a matching remote.
I also removed the original motor and replaced it with one that fits exactly in the original mounting (after removing the magnets). I remember running the chassis by coupling it directly to 4 AA batteries and it was a decent speed but certainly not fast. I can dig up the detail if anybody is interested.
To utilize channel 2 I'am experimenting with a buzzer system.
It uses a servo's innards as shown and works well.
But I need to replace the buzzer with a hooter sounding like a train and grandson can flick the second stick every now and then when approaching danger op peeping toms (grandmother or his mother etc).
This is my charging setup - and remember I am a noobie.
All bought in China via ebay and very cheap.
The LH top gadget shows the voltage after a session as well as after charging and works a treat.
It can also be used as an alarm which I assume one sets to a minimum voltage and the buzzer will go off.
At this stage I simply use it as a volt meter and so far after a day's running and charging it seems to be sufficient.
At plugging in the charger shows 2 red lights for my 2S batteries and turns to green individually as the cells are charged.
Every running session starts with batteries fully charged at 8.38 volts.
The left side cable is an extension cable. The idea is to place (glue?) the battery's charging plug somewhere accessible on the engine unit and to use the extension cable for charging. The battery can then remain permanently in the train.
And lastly I hope to master an Arduino system.
I started off with the Arduino and bluetooth board only to discover I also needed a motor circuit to connect it all.
I got the software sorted and the motor circuit (all on Youtube) and discovered the HC-05 Bluetooth board is without the signalling circuit - so I'am waiting for the postman.
The phone app is Roboremo and free from the play store.
I think it will be cool to run the train, lights, sound etc from my phone and I suspect in time the grandson will take to it - at least for the indoors sessions.
All the parts are small and will easily fit in the O scale units and I suspect it may be the cheapest RC system of all.
Thanks for all the photos! Sometimes pictures can tell someone a lot more than pages of instructions. My first couple of conversions to BPRC look like rats nests of wires on the inside. But, as long as it works that's what really matters.
Got another conversion on the workbench that should tirn out better than my first two.
Keep up the good work!

I also have this sound unit from China for about $3.
Copy train sounds onto the SD card or memory stick and fit it all into a wagon.
I've copied and converted my grandson's favourite Youtube train cartoon music https://www.youtube.com/watch?v=Qt7ZRVaMhm8
into MP3 and onto the memory stick.
The sound is tinny but I suspect it's because of the speaker salvaged from my neighbour's garage (he's a radio ham with hundreds of bits and pieces) and I'll soon get a decent speaker.
I would love to tie it into the second channel to switch it on and off but at this stage we operate it separately from the remote.
Do remember that for a 3 1/2 yr old kid the magic lies in things happening when he operates the stick.
Anybody that can point me in the right direction?
