Re: Mitchell Castle battery/radio control

I'd have used a slightly different switch arrangement - a SPDT (aka "changeover! switch), so that in one position it would connect the charging +ve to the battery, and in the other position connect the battery to the receiver(and rest of loco). Thus the loco must be turned off in order for the...

Re: Mitchell Castle battery/radio control

David Catton very kindly took my badly hand-drawn sketch and turned it into a nice circuit diagram showing the components and connectors, that anyone can understand (hopefully). So the above RC connections I've put together for the Castle are like this: Wiring-Diagram.jpg And were you using a 12v mo...

Re: Mitchell Castle battery/radio control

Hi folks, A quick update, as things are progressing slowly but steadily on my Castle project. As I mentioned on one of the other R/C threads, I wanted to tidy up how the various components connect together. So far I have been using small stripboard pieces with components either soldered to them, or ...

Re: Brassmasters Duchess test build

Looks awesome. Really nice clean job. Presumably the holes in the back of the axlebox castings allow for the movement of the axles? Or you had to grind them out?

Cheers, Nick

Re: Mitchell Castle battery/radio control

A little bit of progress. The main Castle chassis has gone together with no drama. CSB as usual with High Level horn blocks and carriers. Some minor modifications needed to the spacers but nothing too drastic. As I'm driving the centre axle I needed to move the centre spacer forward a bit. I will so...

Mitchell Castle battery/radio control

I'm going to build 4094 Dynevor Castle from a Mitchell kit that I bought from eBay about 18 months ago. The box included a 4000 gallon tender. I've never actually built a tender locomotive, although I have a couple half-built. So this is going to be a voyage of discovery... It will carry the battery...

Re: Components for RC

Discussed with David and recreated the Excel as a Google Sheet:

Components for Radio Control

Works the same as Excel but is online and shareable, and other people can add/edit.

Thanks, Nick

Re: Questions

Hi David, I've not tried this, but I think Ted can confirm, you can bind multiple receivers to the same slot on the TX, but I don't know what happens if more than one are switched on at the same time. So you could have a set of 12 locos bound to the 12 slots on a TX, and then another set of 12 locos...

David is it possible that we can change this to a Google sheet? They work exactly like Excel but shareable and accessible and there'll only be one version. We can make open via link and it means that everyone can see it and add to it. I only have Excel on my work laptop. This could be a very useful ...

This is great David, thank you. When I get some time over the weekend I'll add some of my own stuff. I will also start a thread about batteries as this is an area that deserves it's own topic.

I agree with Keith, lets start a new thread. There's already one for motors, maybe start one for batteries?

Re: MItchell 45xx battery/radio control

So I just wanted to close this thread out before I do a post about my next project. I took 4556 to Mr Scannell's house yesterday so we could measure the traction pull on his test track. If any of you have seen this you'll know how it works, but basically it has a little pulley and a weight and some ...

4556 with it crankpin nut fixed, buffers, coupling hooks and coal. I've somehow managed to get the weight up to 232gm. It runs nicely on my tiny test track, but on Saturday we'll hopefully see what it'll pull using Ted's traction testing thingy. I've also figured out that the videos look better if y...

4556 is basically finished now, with a bit of light weathering using oils and powders. I just need to fit the buffers, coupling hooks and add some coal which I'll do over the next couple of days. It runs nicely, and I was going to make a video to demonstrate, however it seems to have lost a crankpin...

Re: MItchell 45xx battery/radio control

Thanks Alan. The next time I'm in Halfords I'll pick one up to try. I've had problems before with masking tape lifting off paint and primer back to the brass, which is really annoying! Maybe this will help. Cheers, Nick
