I am a new novice member who needs help getting started with radio controlled loco

[Brain]

 

I have become curious about radio controlled. The idea of starting with digital doesn't appeal to me. Was advised by a friend who is on this forum and has just become a member himself. Radio controlled is not yet that common in Sweden, more than with a group that runs a live team in 1/18.
 
I a assembled Loco n Stuff, Peckett Cranmore 0-4-0 0ST in 1/35 scale.  see picture below. My first question is what kind of motor should I change to?
Preferably links to what I can find engine.
In the process of building a facility that measures 600 x 3000mm and will run 3-4 carts at most. Rise is at most 35-40mm at 1000mm

I've read through the thread and found this exemplary help from 2019. (see below)
But maybe something has happened and there are now other better components?
Would greatly appreciate help with a revised list of links if there are other smaller and better components.
I understand radio control has come the furthest in England so I understand that may be where I will get to shop.
If you have any tips on places to buy within the EU, I would be overjoyed as I live in Sweden. Namely, I have some bad experiences with postage, customs and delivery time after Brexit on car parts I bought for my old Morgan from 1967.

 

Sincerely
Michael Brane

This was shopping list from another thread.
 
Single cell 3.7v battery with UM connectors - you can probably fit quite a large one in a Lima body

Rx41d-x-v5 DSM2/DSMX Micro Receiver with Bi-Directional ESC (pre-wired version)

UM battery extension lead chopped in half to give me a charging port - get another one for the charger

Micro slide switch to turn it off/on (always better to charge it when it's off)

My controller is a Tx22

Voltage step-up if more power is needed (you may need an Rx6x receiver to handle more voltage)

The wiring is (obviously) the important thing to get right.
 
-Charging port and battery need to be permanently connected
-Battery and Rx need to have on/off switch in between them
-Rx and motor need to be connected the right way around

You may find components in EU-land by searching for 1:87 scale radio controlled road vehicles.  There is a lot of activity, primarily in Germany, in that area(*),  far more than goes on in the UK.  

 

The things you need are:

Transmitter, to select the loco and send speed/direction instructions.  

Receiver, with a reversable H-bridge output to drive the motor (in two directions).

Battery, to power the receiver and motor. 

Switch, to disconnect battery from circuit when not in use.   A change-over switch which can swap from "powering receiver" to "charging contact connected" is very efficient, and only needs to be a single pole change over switch.   

Charger for battery, which needs to match your choice of battery. 

Connectors/contacts to enable charging.  

 

If really stuck for space, then omit the switch, and just disconnect the battery when not in use (and thus with battery disconnected, it is possible to attach charger to battery).  

 

Road vehicle receivers would be fine for a loco, as you just ignore any servo outputs for steering !    Transmitter will depend on your end-goals - if it is only one loco running at a time, then any transmitter compatible with the receiving device is fine,  but if wanting to switch between locos, then something which can switch is required (but that also applies to road vehicles, so there's likely stuff available).

 

Charging single cell Lipo batteries (typically around 4volts) is a lot simpler than charging multiple cells.  So there is some sense in trying to design around a single cell.    Cells are typically quoted as a capacity in "miliAmp hours", more capacity runs longer, but takes up more space.  

 

As a single Lipo is around 4volts, ideally a motor in a model needs to match that.  Or, alternatively, there are voltage increasing circuits which can be fitted (increase the volts, though that will deplete the battery quicker).  

 

 

(* I've recently imported some parts from SolExpert in Germany for a very small 4mm scale loco).

I’d look at Giles’ topics on radio control ;)

In the UK. You already have them in you list. But http://www.micronradiocontrol.co.uk/ 

have a really good reputation for their knowledge and helpfulness particularly with respect to the deltang receivers and transmitters
