|It's been suggested to me that these:
can be used as a simple on/off, forward/reverse, with no speed control,
in 16mm scale I.C. narrow gauge locos.
Not too sure about how to wire it.
But does anyone have any experience of these?
And if so, how did you wire it?
as has been pointed out to me already in another query I posted,
the 'instructions' are a tad vague .....

If it doesn't have speed control (proportional) then it probably isn't what you want.
With that stated, I started off into r/c with little cheap r/c car boards which had no speed control,
but when I installed one in a 1:48 railcar I built with a Grandt 80:1 gearhead motor,
it worked quite well.
The geared motor would "spool up" and then go top speed, about 10 SMPH,
and when stopped, it slowed down OK. All because of the gearing.
If this isn't much money and the board is small enough,
I'd say get one and mess with it.
I usually use Deltang stuff which suits me well,
but someone I know (whom I've now directed to this forum!)
tells me he uses it as a simple 'basic' control.
I've ordered 3 from ebay China.
I plug everything with JST 1.25 connectors,
so swapping in and out Rx's is easy.
At the price I can afford to blow a couple,
says the man who's score at throwing flaming Li-Pos out into the garden,
recently went up to 2 !

Yep, I have had that happen over the years.
I threw mine down the alley so they could explode behind the neighbor's house.
The little r/c cars that I used long ago were "Zip-Zap" 1:64 scale cars.
The boards were tiny, but I could run them with a 1 cell Li-Po or even a 2 cell job.
Those little cars cost about $7 USD, but after Christmas I could find them for $3 or even less.
I have looked but haven't seen any in years.
I guess I should have bought a case lot so I could have a few to mess with.
|Well, they've arrived in only 10 days.
Maybe they were the last items into the container!
I've asked the chap who suggested it,
and has used it successfully in a 16mm loco of his own,
for wiring info.
Once I've got one up and running,
I'll be in a better position to add to this post.
Hopefully without my Li-Po-flinging score going up!
|Happily the guy who put me on to this, came back quickly with info and pics.
Managed to hook it all up and after an ok bench test swapped it into a Saltford Ruston.
Even managed to reprogramme the Rx to latch.
Also found that if you go straight into reverse it changes the output polarity,
not really a problem in a loco but could be if powering a garage door!
Also if battery voltage starts to drop it can become stuttery.
Inadvertently I also found I had inching before latching,
but can't replicate that now, maybe just as well.
Range test was fine at 40ft.
Tx takes a CR2032 cell.
Yes, limitations, but ideal for test, and my grandsons should be able to use it ok,
even the 2 1/2 year old one can use a Deltang Tx22!
I'm finding this RC lark quite good fun.
