That may reduce some when you RC it, but still probably enough for a days running for you.

Yes indeed Jon. However the normal running day on the CFR is from 10am to 4pm so it won't be a problem. My Roundhouse Harlech and Criccieth Castle class locomotives only run for four hours on a full charge.
 
Are those bevel gears the same size? They look as if they are, in which case the loco has no reduction gearing. Not bad statistics for a direct geared loco on batteries!

Yes indeed they are Andrew. Yesterday she again ran at a steady 8mph for eight hours hauling seven wagons.
 
The gears are built inside the motor casing on these types of motors which were probably developed for power tools.. Several ratios are available.

Yep, and the motors have very low current draw. Generally referred to as Como Drill motors, there's more than one manufacturer and, in the smaller scales, there are motors with exposed gear heads so you can see how it all works >:)>:)>:)

Looking at the last picture again I am trying to wonder what the bit in front of the Fuse is that is wrapped in Heat Shrink. A speed reduction device perhaps?
 
The black 'blob' is the Electronic Speed Controller (ESC)..

This is controlled by turning the 'exhaust'. - I just wish the potentiometer nut was concealed in some way. The only poor detail on the loco, IMHO.

Yeah, on my blue and yellow dismal, which currently languishes with a dismembered chassis, I mounted the potentiometer on a sub-frame and soldered a length of brass tube for the exhaust pipe. The drawback with my arrangement is that the brass tube is really too small diameter. OK, I could solder a larger one outside..........

Pass me my round tuit.......................:emo::emo::emo:

Aha I get it now, re reading Pauls initial post it does say about the esc. Just not apparent in the dismantled picture as the Exhaust will have been taken off to undo the nut and get the body off presumably. Just a thought a dab of black paint on the unpainted parts would make all the difference.

The body and cab lifts off in one piece. No need to remove the exhaust. I considered painting the nut and fittings, however a rubber grommet will cover the same area. I'm also planning on fitting a lamp, horn and cab steps. Weathering will also be applied.

I will be interested to see how you go about that, Paul..
 
PhilP said:
Quite like that..
Think it needs an 'oily rag' wiping over the 'plates, and possibly the front windows?
:clap::clap:

Yes indeed. More light weathering and a little bit of buffing required. It is intended that the locomotive represents a hard working but not neglected life.
 
Nicely done. i see tag Gorton has been doing similar in Garden Rail magazine.
 
I think the old knees are catching up with him - like the rest of us. Steam rescue loco.

Yes indeed. Great minds think alike Alan. The next step is to convert the locomotive to radio control. I have a Timpdon GX system to install. This will be done sometime this week.
