" Another aspect that interests me is the switch provided with the ESC's."





Hi George :wave:



I believe that the ON/OFF switch, connected to the 'flying-leads' emerging from the E.S.C ...

... is pretty much directly wired-out again, to the battery connector, as I recall.





The fact is, that the E.S.C.s microchips & those in the 'FlySky' receiver, both use MINIMAL power to operate.

Compared to a motor, particularly a BIG one, the battery drain is pretty small.



Having said that ...

... leave it switched on for a week & the chances are you may have a flat battery ! :f:

I would think turning it on & off DURING a days operations, would make little difference to battery life.

I'd just switch ON at breakfast & OFF at dinner ! ;)





George, go on ! ... Start a Thread on your 'FlySky'ed  R.C. loco ! :thumb:

There are O-scale R.C. fans out there, that need to see this kinda stuff !! :2t:



:!:



Si.



Of course you could go for the :brill: Einstein approach George ! ;)

I'm sure you've got a regular electrical multimeter.


So, probes connected 'in-line' with the batteries & the loco at a standstill ...

... BINGO ! there's your standby power consumption in milli-Amps. :cool:


I'd do it myself, but I'm still messing with my components ! :shocked:



:slow: :slow: :slow: :slow: :slow:

Ok Si.

I allow about 20mA for a Rx/booster combo idling in a siding, say 25 hours for a 500mAh battery

Local fixer upper of RC stuff has standardised on 'FlySky' 2.4 GHz.
He is my source of cheap 27 MHz transmitters and receivers - which helps (pensioner).
BUT now that I've lernt how easy and convenient it is after setting-up the tracks to whip in the batteries and away we go.
I wouldn't mind going for the 'FlySky' stuff when we get outdoors.


George


NO not smoking pot (yet) :)

I seem to have a few potential candidates for the 'FlySky' R.C. install at the moment. L:

I'm not sure if I want to R.C. all of my locos though ?

The idea of using BOTH track-power and R.C. together is appealing.



But I am considering how I could install R.C. on all my loco projects, just in case ! :P





My trusty ol' topless Porter, sans cab, and now sans rear wheels & fuel bunker ... :shocked:

... is getting a new tender, inspired by my favorite Porter with a tender photo !





Somehow or other both my Porters new cab & tender are taking shape from this inspiration. :thumb:





The new tender is based on a heavily modded & re-wheeled 'Tri-ang' Transcontinental passenger truck.

The trucks end-beams have been removed, which I don't do on car builds, to allow for the San Juan Car Co. 'Evolution' couplers.



The woodwork has been made from some of my favorite 'obechi' stripwood.

I may use the tender at the length in the photo.

But have given myself the option to shorten it by 1 or perhaps 2 planks worth, if I decide on a bit more of a 'shortie' look ! :cool:



:!:



Si.



As for the Plymouth at the moment, I'll probably come back to that in a while.

The Porter is def. the R.C. priority at M.M.M. for now at least. :)

I was uncertain about the size tender I wanted. ???

So as a pointer the vintage prototype photo gave me a few basic scaled measurements to work with.

Basic length in relation to the loco & height were derived from a 'measured sketch' on graph paper. :)



The Porter in the vintage photo, is of course a larger 3' gauge engine. :shocked:

But the proportions in overall length still look OK for my 2' gauge 1:35n2 version.

Perhaps a board or two shorter in the tender, as considered. :P








My mahogany front-beam is yet to be trimmed to the correct width by the way. :old dude:

It was an experiment in creating a square 'mortice' in the timber ...

... for directly fitting a San Juan Car Co. 'Evolution' coupler. :cool:



The even keener eyed out there, might notice as well, that the coupler is also upside-down ! :P

The M2.5 coupler pivot fixing would normally be underneath the locos end-beams.



:mex:



Si.



I don't think I'll use Joseph Stalin as the fireman in the final model either ! ;)
