      As just mentioned in another thread (**LINK**), I'm about to begin my next model boat build, which will be a 1/16 scale Fairey Huntsman 31 from Dave Milbourn's set of plans that were first presented in the January and February 2016 issues of Model Boats.

      fhbygg1.jpg

      When I decide on what to build, there are usually two main considerations.

      The first one is of course quite simply that the subject is one that I find attractive. I am on the whole not a major fan of motor or speed boats – de gustibus, and all that – but the Fairey family are certainly an exception to this rule: I find them very pretty indeed!

      The second consideration is what challenges I want the build to provide, and with this one that is going to be the use of a brushless motor and up-to-date (read: LiPo) battery technology, neither of which I've any experience with.

      So. The other day I got out the plans and the relevant MB issues, both to re-familiarise myself with the project, and to figure out what building materials I would need to get started …

      fhbygg2.jpg

      An order was subsequently put in with Slec for i.a. lite-ply and some balsa blocks, and I am now waiting for them to have time (surprise, surprise: with all UK model builders in lockdown, mail order suppliers are very busy right now) to fulfill said order.

      In the meantime, I'll keep re-reading Dave's two articles and also some of the other documentation that I have collected over the last couple of years.

      Oh, and I should perhaps explain the choice of name for the boat, too?! Well, Sweet Sue (Just You) is of course a jazz classic, written in 1928 by Victor Young and Will Harris, but also, as my wife's name is Susanne, a song with a certain personal resonance (f'rinstance, my wife's mobile phone ring tone is me playing and singing Sweet Sue …). And as I believe it to be not uncommon for vessels of this kind to be named with reference to an owner's significant other, well, Sweet Sue II seemed appropriate enough to me …

      To be continued …

          Ah-HA! I shall sit back, crack my knuckles, pour myself a large JD and watch this unfold….. I have been looking forward to having a Banjoman-build of one of mine for a long time!

              Dave,

              In which case I think I'd better refrain from pouring any JD (or other amber liquid of equivalent effect), at least pre-any building session …

              Paul,

              Is this where I say "I have a cunning plan"?

                  It will have to be a plan so cunning that you could put a tail on it and call it a fox.

                    Hi Mattias,

                    Welcome back, we have missed your boat building, "nobody does it better" to coin a phrase

                    All references to Allo Allo more than welcome, I just love that series and have the DVD box set, and your in the right place !

                    Regards Ray

                        Hi Mattias,

                        Its good to see you back on the forum and about to start another project. I am sure your model will put even Dave Milbourn's Fairey in the shade when its finished to your usual high standard.

                        Seeing the clock on the wall of your apartment reminded me of the one I made some years ago. As a small boy my favorite toy was Meccano and I was fascinated by gears and gearboxes, In my final year at university I designed a transfer gearbox for a lorry as my design project. However it was not very good as I was never very happy starting anything from a clean sheet of paper.

                        One day thirty odd years ago, I told my wife I fancied building a clock from a kit. What I envisioned was assembling lots of brass gears into a working mechanism. However, what she bought me for Christmas 1989 was a complete clock mechanism and chimes plus the plans for a Vienna regulator case. Progress was quite slow as I did not have a lathe to make the columns and finials but eventually, after some improvisation the clock was completed 10 years later.

                        clock1.jpg

                        For Christmas 1999 she bought me an engraved brass plate to fit inside the case.

                        The clock is still on our dining room wall but very rarely gets wound up these days.

                            Gemplemorums all,

                            Warmest thanks for all your kind words of encouragement – I can but try my cunningest plannest, eh wot wot …

                            Apologies, too, for slowness of reply – I've been pretty busy these last two days with setting up a new computer.

                            Dave M.,

                            I'm afraid I've learned the hard way not to combine these two pastimes, as my patience (already in short supply under the best of circs) tends to go out where the Ardbeg goes in. Just as these days I prefer not to drink (very much) beer during a gig, as opposed to what was often the case in my well-spent youth …

                            youngmanwithabanjo.jpg

                            Paul T.,

                            Hmm … Boom, Boom?!

                            Ray,

                            I never really went away, but I will admit to mainly lurking for a goodish while, now.

                            And I, too, very much love 'Allo, 'Allo, not least because the original BBC drama series of which it was a spoof, Secret Army, was a huge hit on Swedish television where it was broadcast during the summers of 1981–1983, i.e. when I was in my teens, and I still have very vivid memories of the whole family gathering of an evening to catch the latest episode. The original was not set in France, though, but in Brussels and Belgium, but I dare say that the comedy makers' box of cliches was rather more well filled when it came to poking fun at the French than at the Belgians … ?!

                            That said, my "cunning plan" refrence was rather intended to call up Baldrick of Blackadder fame …

                            Ashley,

                            No, no – those are jigs for making hot air balloons, dontcherknow!

                            Gareth,

                            That is a beautiful clock! A very impressive build, and the plaque is a really nice touch!

                            Mine is more of a family heirloom, although not at all in the "valuable antique" sense of the term. It is one of those mass-produced eight day clocks from around the turn of the previous century, in Sweden often called America Clocks, because (a) many were made over there, and (b) they were not uncommonly sent as gifts to remaining family by sufficiently successful Swedish immigrants to the US. They are very common, and in monetary terms more or less worthless.

                            klocka1.jpg

                            However, when it comes to sentimental value, it is a different story.

                            In rough numbers, about a million Swedes emigrated to the US between 1850 and 1920, at a time when the country had a population of between three and four millions. My paternal grandfather, whio was a Master Blacksmith, was one of those emigrants (as was his sister), and he spent the years circa 1895–1905 in Chicago. He then came back to Sweden to help take care of things at the death of his father, and, what with one thing and another, never went back. However, it was only in 1927, two years after my uncle was born, that he finally disposed of the plot of land he'd up until then had had in Chicago and where he'd intended to build a house. He died in 1954, so alas, I never knew him.

                            In any case, whether it came with him from America, or was acquired some other way, the clock initially belonged to my great grandmother. After her death, it came to my paternal grand parents, where it remained until my grandmother died in 1968. It then went to to my father, but as in 1968 he already had two young children, one of whom was I, with two more arriving in the next few years, my parents wisely decided not to hang it in the house. Instead it sat, unwound, on the wall in what, when the apartment block was built, was intended to be the maid's bedroom, but which my father used as a sort of box room to store his paintings and painting paraphernalia.

                            Then, around the time that the above photo of me was taken, i.e. around 1986 or 1987, I asked myfather if he wouyld min if I were to hang the clock in my room, and set it going again? He of course said "no worries", so I put up a hook, and hung it on the wall of my room (I was still living with my parents at the time), roughly three feet from where I'd put my head on the pillow of a night! For the first three weeks, I had to hang a dressing gown over it at night, to stop the chimes from waking me up, but after that I'd gotten used to the sound of the ticking and the chimes, and to this day, I hardly ever hear it. In any case, I have kept it running ever since, and so far it has just kept ticking along. I dare say I should have it cleaned and serviced one of these days, but as long as it keeps going, I'm sort of disinclined to bother it with too much TLC. It slows down a bit towards the end of the week (I usually wind it on Sundays), and then speeds ahead when newly wound, so while not accurate to anything within 10 minutes or, it is more or less right on average, and good enough for an o'clockish approximation of the time …

                              Anyway, delightful asides aside, today I took delivery of a nice, hefty parcel from Slec, with a goodish bundle of ply, liteply and some block balsa wood …

                              fhbygg3.jpg

                              I hope it goes without saying that it is not all intended for this build – it's just that I though I might as well replenish my stock of of these materials while I was at it.

                              I already have most of the drive train, in the form of a brushless motor with corresponding ESC, a motor mount, a bronze propeller from Protean Designs, a propshaft and an SHG flexible coupling, all of which I bought at the IMBS back in November 2017 …

                              fhbygg4.jpg

                              Before I actually start doing all that much in the way of building, I shall want to complete this with some LiPo:s, a r/x for my radio and a steering servo and rudder linkage. I will also need to check my stock of silicon wire, Dean type connectors, and other such stuff, although I think I'm good to go for most of those.

                              And if I'm going to use LiPo:s, I should probably get one of those low voltage alarms as well?!

                              Oh, and some glass fibre cloth and Z-Poxy resin, too!

                              So, still some thinking and buying to be done. A lucky thing that all this sort of stuff can be easily ordered online! Usually, I would get most of this kind opf stuff over the counter at one of several very well stocked model emporia within half an hour's drive from home, but right now, not so much opf that. So online I will go

                              To be continued …

                                At this stage of my pre-build collection of bits and bobs, I would very much like to ask for a spot of advice on a couple of LiPo-related matters, before I send an order off to Component-Shop.

                                As already mentioned, I picked up a motor (Leopard LC2826 1150 Kv) and corresponding ESC (Leopard Marine V3 30A) back in the autumn of 2017, specifically with this build in mind.

                                fhbygg5.jpg

                                Based on Dave Milbourns article in MB (January and february 2016), I am now planning to add the following:

                                • Giant Power 11.1V (3S) 2600mAh 35C/70C LiPo (**LINK**);
                                • In-line low voltage alarm w. Deans connectors (**LINK**);
                                • LiPo Battery Fireproof Bag (Large) (**LINK**);
                                • ACTion P106 In-Line Power Switch (**LINK**) and a small toggle switch;
                                • Leopard Program Card for RC Boats Brushless Speeed Controller (**LINK**)
                                • Some lengths of black and red silicon wire in various AWG (for use on this project but also to stock up).

                                My first question is thus if anyone has any comments on or suggestions for improving on this list?

                                As this is my very first brush (ha!) with brushless and even more the first time I even consider using a LiPo battery, I will admit to being slightly apprehensive, given all the dire warnings surrounding said LiPo:s. It is not so much that I fear being unable to understand how to handle them, but more that it seems that they are more likely to suffer from neglect, and should be charged/discharged/balanced about once a month?!

                                Now, I know from my experience with Pb and NiMh batteries that I'm not all that great when it comes to remembering to give them their TLC sessions, but with those chemistries at least the worst that'll happen is that they become tired enough of life that I lose my investment, and have to buy a new one.

                                The thing is that what with all my other hobbies and interests and work and life in general, I don't tend to get to the pond all that often, even during the season, so am unlikely to be reminded about cycling batteries through frequency of actual use.

                                My second question is thus how sensitive you have found LiPo:s to be to neglect? Will they just cease working properly if I forget to cycle them every month or so? Or will they become dangerous, either to continue to store or (even more so) to use again?

                                Finally, as far as I can figure out, my current charger (a SkyRC e6650) should be fully capable of handling all the necessary charging/discharging/balancing of the kind of LiPo pack mentioned above.

                                My third question is thus whether I'm right in thinking that I don't need to get another charger?

                                  Hi Banjoman

                                  In reverse order.

                                  Your battery charger is fine. I have the same one myself and find it great for all the battery chemistries and easy to use.

                                  I have some electric model aircraft and the batteries get little use or treat due to lack of time and opportunity. Recently I tested some and found they worked OK. I would anticipate some loss of capacity and I would be cautious about using them in a high value model or a precious one. I wouldn't have the same concern in a boat. And no, so far none of them have exploded!

                                  Your list looks fine but I have ditched my LiPo charging bags and used the material for other purposes having seen some Youtube footage of their effectiveness.

                                  I am not an expert – just my experiences.

                                  Following because I really like your work and I am a Fairey Fan. Born and bred on the Hamble River.

                                    Hi Mattias,

                                    I would back up Tim's comments about lipos they need respect, but I've been flying with them for about 10 years, my observation is leave them charged, and keep an eye on the cells venting the plastic casing starts to inflate slightly, they are still usable. I use the 11.1 volts 3 cell 2200mh, they don't have a long life compared to a nicad packs in my experience.

                                    My cheap and cheerful balanced charger has a separate light for each cell and you can see if one of them has failed which is useful 😀

                                    Regards Ray

                                      Hello Tim,

                                      Many thanks for your very helpful reply!

                                      I was not least very interested to read what you had to say about charge bags and their (lack of) effectiveness. I have also cast a beady eye on the Robbe RO-Safety LiPo Vault charging and storage box (**LINK**). As it is rather more expensive, it might, best case, also be more effective! Or, it might just be more effective at taking one's money from one?!

                                      Do you or does anyone else have any thoughts on that?

                                      I'm also glad to hear you say that LiPo:s should be able to survive at least normal levels of neglect – that is at least a small weight off my mind

                                      Again, warmest thanks!

                                      Cheers,

                                      Mattias

                                        Hi Ray,

                                        Thank you, too, for those reassuring words

                                        Kind regards,

                                        Mattias

                                          That LiPo pack looks to be just the ticket. I think it’s the same type and size that I used in the prototype Huntsman.

                                          The V3 Marine ESC you’ve bought has an automatic voltage cut-off which you can program if required. I left mine at the default value which is 3.2v/cell. That being the case I don’t use an inline voltage alarm with this type of ESC although I do have a separate voltage tester. Battery Status Checker

                                          The programming card isn’t vital but I bought one and find it much easier to use than relying on bleeps and flashes as you fiddle about with the throttle stick.

                                          The ESC has a small switch which turns the receiver on and off. I leave the LiPo disconnected until it comes to the point of sailing, at which time I plug it in and use the switch to activate the radio – after turning on the Tx, of course! I don’t think the P106 has been produced for a long time, although I have several and use them with my other choice of brushless ESC [Fusion Hawk]. If you decide that you really want one then let me know and I'll see what's in the magic toy-box.

                                          I’m also a bit of a lazy beggar and I don’t have a routine for maintaining my LiPo packs. To be honest none of them has been recharged since its last use, which was last year! I do store them in the fireproof bag and they all seem to maintain their nominal voltage. Maybe I'll check them again later today….

                                          The charger is specifically designed for several different Lithium battery chemistries SkyRC Charger and so you don't need a different type

                                          Hope that answers your questions.

                                            Dave,

                                            Yes indeed – that, together with the postings from Tim and Ray, very much answers my questions!

                                            As for the P106, I note, now, that it is indeed out of stock at the Component-Shop, and of course your suggestion of not bothering with a switch but just plugging in and unplugging at the pond side will work just as well. In other words, many kind thanks for you offer to look through the toy-box, but there's really no need.

                                            So! A-shopping I will go!

                                            Cheers,

                                              I quite forgot to say about the in-line voltage alarm that I was indeed aware from reading the ESC instructions sheet that there already is a cut-off included, but my thinking was that an added alarm, set at a slightly higher threshold, coukld be helpful if set to sound a warning before the actual cut-off threshold was reached?

                                              Or am I being too belt-and-braces here? Said instructions for the ESC to seem to say that cut-off doesn't mean that it stops dead, mid-pond, but rather that powert is reduced but with sufficient time to bring the boat back to shore?!

                                                I recently tried to program a similar Esc by the same manufacturer without the programming card. I thought that the card I had would be ok .

                                                After several hours counting bleepsI gave up and bought the appropriate card, it seemed I needed a car or ground card for this Esc.

                                                After 2 minutes it was programmed and working just as it should.

                                                So unless with your musical background your better at counting bleeps I would get a card.

                                                  Yes, that's pretty much what I figured, and I'm happy to report that I have now ordered the programming card in question, together with the LiPo and so on.

                                                    I've never got any of my LiPo packs down to the state of discharge where a cut-out might become active so I can't comment on what exactly happens with that one. That said, I wouldn't trust my own senses to detect either a warning beep or an LED so I have to trust to automatic gizmos.

                                                    Anyroad up, m'duck – it's not slim young folk like you who need either belts or braces; it's fat old b*****s like me!

                                                      Righty-ho. That does indeed sound as though a belt will be sufficient to keep the boat's trousers up, or in other words that I won't bother with the additional alarm.

                                                      And, alas!, even (relatively) svelte, (relatively) young'uns do need summat to keep their britches from flying at half-mast …
