If you don't want to use a brushless motor then a standard 540/1 will do, with a 7.2v NiMH pack and a 15-20A ESC. https://www.componentshop.co.uk/540-standard-dc-motor-mounting-bracket.html

I have no confidence attempting this so would like to see this done, from start to finish, any videos anywhere... anyone?   :-)

hi there


I believe this is the type of rudder I used in the build of my original of the Fairey Swordsman but - I can guarantee that I didn't pay the price they want on here (see link) - I believe mine actually came from a model shop - but - that is when there were more model shops around.  If it were me I would do as suggested - put doublers either side of the keel & use the rudder that you have.  I didn't realise this build was still around - it must have had a few views now :-) .     This was a nice model to build - and - I do have the plans for the Fairey Huntsman (the one with the brushless motor) the owld "xxxxx" Milbourn drew that to do sometime in the future.

Just wondering which five-letter word was XXX'd out there, John....
I think this would be nearest to the rudder I used - subject to checking the dimensions.  https://www.modelboatbits.com/MINI-RUDDER   It was a long time ago now (>20 years).
Are you still as young and lovely as you were when first we met?   :kiss:
Nah - me neither!

'XXXXX' should actually 6 x's hahaha Dave - so why put 5 I have no idea.  But, it has the same meaning as our friend with the laptop programmable speed controller  :} after he has shoved too many amps through it - aye - he has never let us know the result has he?

Hello Dave / Chris / John / all


Thanks very much indeed for your various replies. I hadn't realised that there were new replies. I used to get emails telling me when this happens, but apparently not any more, oh well, i shall try and check more often. Mind you i have been so busy at work, and then with my studies outside of work, and then the wife has had me at decorating as well, there has hardly been any time anyway.


It's interesting that none of the articles / videos etc seem to talk about combining ezekote and tissue - presumably people just don't do that, but what i am wondering is, is there any intrinsic reason why you couldn't do that ? (seems unlikely, but i suppose glass fibres are ultimately silicon, so pretty much inert, and conversely i suppose the tissue may just have some kind of volatility against the ezekote or vice-versa ?)


It seems that brushed motors need / may need supressors (due to the brushes i think), so i guess that's an additional complication over the brushless, on the other hand the 540 motors in general are somewhat cheaper (I see that there is one for 5 at action electronics at present). Do brushed and brushless require different types of speed controllers ? Then i guess i need a "BEC". Ultimately I'm trying to get to the bottom of a rough total cost of either installation.


It it helps/ I have a couple of turnigy 2200 3-cell batteries, 11.1 V, 25c - 35c , that i bought last year during a brief foray into model planes, and i have a charger / discharger that supposedly does ac/dc ,  lipos /  lihv / life / liion / nimh / nicd / pb .  Last year I did the research to understand what the battery specs etc meant, but it's gone from memory now, so have to start on that quest again when i get  the time (I should be attending to my studies even as i write !).


Thanks again.


Best regards

Hi Nick

You're not alone, I haven't done anything on my boats for weeks due to having to do other things, mainly decorating! For email notifications see the Notify/Unnotify tab at the bottom of the page.

I'm guessing that tissue is not mentioned as you usually use something like dope to shrink it and it needs to be thin to penetrate it whereas resins are quite thick. The lightweight cloth works well.


Yes, you do need different ESCs for brushless and the motors are more expensive but for boats like the Swordsman they really are a better choice and unless you've got a lot of boats (I'm building a few!) then the overall cost isn't that great.

Concentrating in the main, on the fine Fairey Marine boats, which is plenty for me to be getting on with!

There has been a lot of information on this Forum already about brushless motors etc. https://www.modelboatmayhem.co.uk/forum/index.php/topic,13538.0.html

In brief, yes they do and no, you probably don't - because most speed controllers have BEC built-in already.

I've tried using Eze-Kote resin with modelling tissue and it really needs something thinner to soak through and make it stick properly, like dope. 34gsm glass cloth is the proper stuff to use, following either my article or the Deluxe Materials video.

Hello all

I like the look of the decking that has been used on the Swordsman that John built, which appears to be the same model in Dave's article https://www.modelboats.co.uk/news/article/finishing-and-sealing-of-wooden-hulls/18771 . Would anyone like to suggest what that is, i.e., is it a veneer, or a ply, and where can it or something similar be obtained etc. Alternately, if that is a very expensive option etc, what might be a good choice of colour of paint, to paint the deck with, to produce something similar looking (I'm not thinking of trying to paint on a grain effect, so just a uniform covering (I'm also not interested in trying to create a teak-planked look)) ?


Also, with the temporary triangle of ply that is used to help with the alignment of the prop tube, I have come to find that I rather like the look of it, in that I prefer the outline of the hull with it, over without it, so I was wondering if it might be ok to keep it as a permanent feature ? I suppose it might make the boat harder to turn, through its effect on directional stability, but on the other hand, perhaps it might actually help in "repairing" the torn / turbulent water behind the tube, as the boat goes through the water, due to assisting with the reestablishment of a "laminar flow" type of situation, so the top part of the rudder might encounter smoother water, perhaps ?


Any advice will be gratefully received.


Thanks
