As proposed by Si the following pics show my trains and remotes.

Thks to this forum and Woodie, Si and Helmut and many others I managed to enter the trainset world for my grandson without the hassle of putting power to the rails:bow:.

I bought a used and battered O scale set with Lima coaches. At the same time my son-in-law made a visit to NY and bought 2 Lionel units on ebay.

I approached a local fixer upper of RC toys and he smiled and sold me a used remote and receiver for $20 not explaining that I also needed an ESC - oh well but I stumbled on.



Grandson just loved the Rock Island loco and that was our first production.

The loco came with a caboose and after some juggling we got the receiver and ESC in.
Stuck down with funny putty.
Also see the link-and-pin coupling as the Lima type slipped too often which frustrated us all.
The ESC (on left) plugs into the receivers channel 1 or 2 depending on which stick one prefers.
The blue and yellow leads from the ESC attaches to the motor and the blue is negative. The power cable black and red ends in a Deans plug to a Lipo battery (in our case).
The piece of wooden bracket (due to 3 lugs snapping off )(I suspect from old age) holds the cabin to the chassis with a screw - works well so far.

The antenna (thin black wire) is simply squeezed in and I am not sure whether that is right or not.
The loco runs well (actually too powerful with the result that when grandson pushes the stick too hard (lacks finesse) the loco immediately derails itself - ouch and I have to go down to ground level (inconvenient at age 69) to get it back on the rails.

The battery fits nicely but the wires need lots of finger squeezing to get the shell to the chassis.

When it's all together it is the best of the 4.
The gears are solid and wide (Lima's are thin slices) and the motor and body is solid and well built.
It performs best with 5 wagons behind as the speed is lower but strangely enough my grandson prefers to only run the loco and caboose combination.
See the screw driver tip - a magnet to hold the screws:old dude:.

The next one is the Santa Fe which Helmut helped with getting the motor going. The green piece on top of the motor houses the bridge rectifier.
This time we got a remote with a knob and by plugging into channel 2 on the receiver the knob is used for forward/reverse/acceleration.
I intend to use the other available channels on all 4 remotes to sound a hooter or light a bright LED - next year:P.
Wiring exactly as for the first loco.

I decided to funny putty the 3 parts to the ceiling of the unit which allows free movement of the motor to stay on course.
The wiring certainly needs cleaning up.
I remove the Lipo's after every day session for recharging (pics to follow).
The coupling has also been changed to link-n-pin.

The receiver.
The plug always has the black wire to the outside.
In this case we've used channel 2 to enable the wheel control and not the trigger.
The antenna is fitted in a non twisted way but I still don't know if it changes anything.

It all fits together very nicely.
The Santa Fe runs far slower than the Rock Island loco and therefore NEVER derails - there's a lesson in that:P.
There are still tiny sparks between brush and rotor and some hesitation every now and then that needs attention - or a new modern motor?

The Lima diesels are also spacious and easy to fit the components.
The wiring is as before and the receiver and remote is a match.
The ESC is the same and supplied by a local RC buggy shop which seems to have taken off over here in parallel to the quad copters or drones.
The DC motor was not working and replaced with a series of brushed motors (next pic).

I started with a 6V low rpm motor (2000 rpm) with a replacement gear from the buggy shop.
The original was 11 teeth and the replacement 10 teeth.
It is working seamlessly but I do expect a shorter life.
With the thin slivers of plastic gears on the Lima's I suppose it is not intended for a long life in any case.
The diesel was too slow to our liking - I could see my grandson was without his happy face:).

Then I fitted a 3000rpm motor - still too slow - and all that was available in 4000rpm from the local dealer was a 3V unit which I fitted willy nilly and now it goes like the clappers (from a 7.4V Lipo) - but for how long?
It needed an accurately carved spacer to get the output gear to mesh nicely onto the reduction set and the sides are simply stuffed with funny putty.
And a strap to hold it in.
