Vintage Gentleman’s Cruiser

[Bob Abell 2Participant @bobabell2]

Thank you, Ashley

I`ve forgotten to mention that it was only a trial run!……I could have made toast on them at one point!

Will be getting the real Mcoy from the Ellesmere show tomorrow

What Amp ESC do you recommend?

Thanks for posting

Bob,

I am puzzled why your motors are getting so hot on no load (ie running with props out of the water). I cannot imagine that the toothed belt drive is inefficient so something else is loading the motors. The only thing that I can think of is that there is a significant variation in parameters (No load rpm, rpm/volt) between the paired motors – so that you have in effect a motor-generator setup.

Hello Ian

You are nearly correct there, Shippie!

Had the other two motors been connected up, it would be a generator system, sort of?

As it was, only one motor on each set was wired up, so the other motor was just idling

The Bobs boards got hot when the motors were not running, because with the BB's, it's difficult to find the Off position

This now leads on to a radical decision

I'm using a tranny with two throttle stix…..F14

One stick for each set of motors….or……One stick for Port and one stick for Starboard

Any sensible reason for choosing which option?

Fascinating?

Bob

Bob. dont get carried away with the theory. the motors will run ok when the paiurs are powered up.

Ii would think that you may get to draw a max of 25A per ABELL unit, so an ESC of 30A per unit will be reqd. As this is quite a bit, I would reccomend two 30A ESC off a Y lead unless you want to have prop steering. This will ensure that the ESc do not get too hot, esp if there is some free-air movement through the boat.

This is a situation that calls for a bit of current measurement I think, boat static in water at full throttle (worse case scenario for max current draw) just to see whats what. i can thoughrougly reccomend one of those little in-line gadgets to measure this, dead easy. i did have a thread 30Wott meter or something a while back.

We used my little unit on trevors project on sunday and it was very enlightening.. Very cheap and as DM found, you can get 100A ones (just in case!!!!)

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you Ashley

Your suggestion is a bit hard to follow…..Sorry

Are you suggesting one ESC of 30 amps per pair of motors, with a Y lead?

Or one 30amp ESC per motor

I'm thinking now…….One Tranny stick per Abell drive set……That would avoid the regen involvement…ie…No tank steering

Do we need Tank steering?

All very interesting

Bob

[ashley needhamParticipant @ashleyneedham69188]

yes, one 30A ESc per pair of motors. Put them on a Y lead and they will both respond to the one stick.

It is much easier to have the normal throttle and rudder set up, unless you will be doing steering competitions, and without a rudder it is tricky to keep a straight line

Ashley

[Bob Abell 2Participant @bobabell2]

Ashley

Something not making sense here?

One 30 amp ESC running two motors

What does the Y lead do?………You don't mean the Rc Y lead………Do you mean a power cable Y lead?

Sorry for being a bit thick

Bob

[ashley needhamParticipant @ashleyneedham69188]

The y lead i mean would be an Rx Y lead…so instead of a single lead from Rx to ESC, it is split…so TWO ESC can be controlled off the one port. Hope that clears things up.

An ESC can run ANY NUMBER of brushed (I thought I would add that) motors as long at the combined current of all those motors does not exceed the ESC rating. My Sunderland has all 4 wing motors off one esc (only draws about 10A max).

[Bob Abell 2Participant @bobabell2]

Thanks Ashley

All is explained…….Apart from the actual amperage for two MFA850 motors?

I will ask questions tomorrow

[Bob Abell 2Participant @bobabell2]

Thank you, Dave

How much and will they be at Ellesmere tomorrow?

Bob

[Bob Abell 2Participant @bobabell2]

Is there no end to fun filled thread?

Well chaps……I just couldn`t wait to show you this!

You must like this scenario?

My Great Eastern mags too!………Will reprint on glossy shortly

Bob

[BanjomanParticipant @banjoman]

Of course! That is what any discerning skipper would read!

Seriously, though, this is looking really nice, Bob: both neat and fun to look at!

/Mattias, who is currently looking into how to reproduce at 1:24 a copy of the June 2nd, 1951 issue of The Evening Times (**LINK**), preferable open to the sports pages …

[Bob Abell 2Participant @bobabell2]

Hello Banjo

I can reproduce it for you

What do you need, exactly?

I can print it and send it to you?

Bob

[BanjomanParticipant @banjoman]

Hello Bob!

Thank you ever so much for your kind offer of help, but I can print it myself, no problem — I have both a colour laser and an inkjet printer, so that is not the issue; my concerns are more on what kind of and how thin a paper (or other material) I will be able to feed through a printer, or even to get hold off, that would at least ressemble newsprint, not be hugely out of scale and which would take the right kind and size of crinkle.

I rather fear that I have just given myself an order on the tallish side, but one option I'm going to look into is to try to sculpt a folded-up newspaper from Milliput, paint it to a newspaperish colour and then apply the visible part of whatever page(s) I select as a slide-on decal. I have bought a couple of sheets of print-your-own decal stock in view of an attempt to print out and apply an Aitkens' 90/ Ale-label to the bottle in the Eilean Mòr skipper's hand, and was thinking that I might have a go at using the same sheet for newspaper reproduction …

Bye-the-by, would anyone on the forum happen to know whether the 1950s The Evening Times was standard tabloid format, i.e. +/- 17 x 11 inches?

/Mattias

PS. Apologies for hi-jacking your thread! If you'd prefer, let's continue the discussion in the Eilean Mòr build thread.

[Bob Abell 2Participant @bobabell2]

That's ok then, Banjo

The right thickness of paper?……….I should have realised that!

Have fun!

Bob

[BanjomanParticipant @banjoman]

Well, the righest possible thickness of paper — I think it would be neigh on impossible to get paper that were really to scale! I'm not currently within reach of my micrometer, but if we assume that 1:1 newsprint is maybe a quarter of a millimeter thick, one would need to find paper that were 0.01 of a millimeter thick but still was sufficiantly opaque … I very much doubt that that could be done, so I 'm not aiming for anything even close to that.

That said, I'm not too keen on regular 80 gramme printer paper either, as I think (again without having measured) that such paper is even in real life thicker than newsprint.

What I'm primarily trying to avoid is what I like to call the doll's house dilemma (from often having seen it in doll's house furniture and accessories), i.e. the phenomenon where an obsession with staying true to the original material makes even a reasonable realism with regard to dimensions difficult.

But we'll see what I can (or cannot) manage; in the meanwhile, I shall step down from this particular soap box in this particular thread, and move discussion back to Bob's lovely cruiser build by asking whether the lounge suite has been made specifically for this project, or if it was something you happened to have to hand already? In either case, I very much like the look of it, and am inclined to think that its slightly non-nautical appearance rather fits in with a pleasure cruiser like the one being built!

Thank you, Dave

How much and will they be at Ellesmere tomorrow?

Bob

I have absolutely no idea whether or not Mike will be at Ellesmere. You could telephone and ask (he prefers that to E-Mails).

The last known price for the FR40 was £25. IMHO this is too little for a unit of this quality.

DM

[CookieOldParticipant @cookieold]

Hi Bob , I picked Mike up from Wigan last year when his bus broke down to take him to Haydock show and i got the last FR40 he had . He said he was not making any more due to the very low margin in them . I asked why he just could not raise the price to accomadate a better margin but he said a higher price would put people off , instead he was going to design a new ESC which would not cost as much to produce . I dont were he is at with that project.

Best Regards Dave

[Bob Abell 2Participant @bobabell2]

Hello Banjo

Sorry, got to admit, my furniture is actually Doll`s House stuff…….£12.00 the lot!

The furniture is not nautical, but it suits the type of craft……..Retired gentleman?

I realise, the quality of build is nowhere near your standard of excellence, but is fit for purpose?

Bob

[Bob Abell 2Participant @bobabell2]

Thank you, Dave M and Dave C

I`m sure to find something suitabell tomorrow

£25.00 was a good price indeed!

Bob

[Paul TParticipant @pault84577]

Hello Captain Bob

The interior look superb and I think this project is the best that you have ever built.

Paul

I hope everyone has a great time at Ellesmere this weekend (and the weather looks fine)

[Bob Abell 2Participant @bobabell2]

Thank you, Paul

We always said there would be plenty of scope for extra's…….Like the magazines and postcard from Russia?

The Dolls house potential is very attractive…….In the engine room, we could have a nice work bench with all manner of tools, lighting, Sink etc ad infinitum?

Ran the motors for Duckie today, and they ran lovely……The multi belts and pulley's are nice to watch, as there's plenty going on!

I take it, you can't make it tomorrow then?

Will take plenty of pictures at the show

Bob

[Bob Abell 2Participant @bobabell2]

Getting ready for Ellesmere show in the Spring sunshine

The Lady Joyce went in the car quite easily……Zafira…….With room for SloMo and Ellie

Bob, Duckie and Pepe

[Paul TParticipant @pault84577]

Hello Bob

No I wont be there but I will be looking at all of your photos.

Lady Joyce looks grand but was it difficult to get down stairs.
