    Hi Lew

    Unloaded refers to the rpm of the motor that it is designed to achieve when it is running in fresh air. The manufacturer for instance may state 10k. rpm on 12 volts.

    Loaded refers to when the motor is actually being used in a boat etc. The resistance of the water and to a lesser extent losses due to the coupling and bearings mean that less than 10k. rpm will be achieved. 80% is usually used, so that may drop to 8k. rpm.

    Obviously using a too big a diameter prop, or one that is very coarse will reduce this further. Hence why I'm thinking that a 40mm prop should be Ok. Better to have a motor spinning freely near its max. design speed than one labouring at a lower rpm and producing heat.

    As Boatshed says, trying different props is the way to choose the best one for this boat, but unlike for a race boat, a number of sizes, within reason should work.

    I still want to be convinced by the battery being used and until sufficient rpm is achieved you are never going to get decent performance. The basics of the battery and particularly the motor have got to be sorted.

    I see what you mean. I seem to remember reading somewhere that confusion arises because some prop manufacturers describe props using one convention but others state the opposite!

    From the Prop Shop web-site: "Please note that propeller rotation is based on theย British and American standard (viewing the boat from the stern) whichย is the opposite to that in Germany."

    As Graupner are German then that probably explains it?

    Rotation a droite is to the right, so as you say clockwise.

    CCW would be counter-clockwise.

    Yes, I was wondering if I should add all the plans as well as I have many of them including kit drawings. But apart from myself, and you previously Bob, I haven't heard of anyone building a Fairey from scratch for a long, long time. Most builds are from the current SLEC kits or refurbs of 1:11 and 1:8 scale Precedent kit builds.

    For interest, a chap on another forum wanted to build a 60" Huntsman 31 with an IC engine (he has access to a lake) and so I've modified my drawings by adding some additional frames and stringers etc. I think these would be of benefit even if building smaller, particularly for producing the distinctive flared bow. If I build another one I will use these drawings.

    Photos show relative sizes of the Huntsman 31 and Swordsman 33. The former is like a racehorse compared to the Swordsman 33.

    What battery are you using to give you 16.8v as that is pretty high and I reckon you should get on the plane with 11.1v/12v or even less as jbkiwi says.

    I think you should be alright with a 40mm prop and I think your problem is a lack of revs. 7000rpm is too low and how are you measuring? If unloaded then definitely too low. You don't want to go too big with the prop as you will probably have overheating problems.

    To plane you want around 9000 - 10000rpm loaded, so around 12000rpm unloaded.

    Can't find the rpm for your Traxxas motor but I did find one on 24v that only revved to 10000rpm so I'm thinking the 16.8v doesn't rev very high either being as it is a high torque motor for off-road vehicles. Nice motor but I don't think it's suitable for your use.

    I can't advise on a motor as I use brushless.

    As requested here is a list of all the kits that have been produced for Fairey Marine boats. Only SLEC and Sarik Hobbies currently produce models. I think I've listed them all.

    Chris

    Huntsman 28

    Kit produced by Veron for a 42โ€, scale 1:8 model. No longer available but may come up for sale rarely.

    Swordsman 33

    Kit produced by Aerokits for a 33 ยผโ€, scale 1:12 model. This is for the aft cabin version where the roof is around deck level. No longer available but do sometimes come up.

    SLEC now produce a kit at 25โ€ where the aft cabin roof is slightly higher but still within the coamings.

    Huntsman 31

    The first Huntsman 31 kit was produced by Modav (Model Avionics) in the 1970s and was for a 34โ€ long model at the rather odd scale of 1:11. The business then morphed into Precedent Kits (Balsacraft) and they continued with the all wood kits but also added fibreglass hulled ones in both 34โ€/scale 1:11 and 47 ยฝ โ€/scale 1:8. Iโ€™ve never actually seen a big fibreglass hulled one.

    The rights to manufacture the kits were then bought by Anglian Model Products but not many were sold and the company has ceased trading.

    Unbuilt kits and built models come up on EBay quite often and are usually the Precedent kits as more of those were sold, though I donโ€™t think the kit design changed much, if at all through itโ€™s various incarnations.

    SLEC now produce kits at 23 ยฝ " and 47โ€ with the latter being a development of the Precedent kit and incorporating some changes to the construction and laser printed planked deck etc.

    Huntress 23

    Sarik Hobbies do a plan and laser cut wood kit for a 23โ€, scale 1:12 model.

    SLEC do a kit for a 34โ€, scale 1:8 model.

    Miscellaneous

    There was also a range of kits for a number of Fairey models but they are too small for practical use and therefore were not popular.

    Thanks. There was a kit of the Huntsman 28 by Veron many years ago and drawings, but you rarely see the kits nowadays. Infact you rarely see Huntsman 28 models at all as they became overshadowed by the Huntsman 31 kits, originally by Modav/Precedent and now by SLEC in the UK.

    The Veron kit and the drawings was too big for me at 42", scale 1:8, and I'm on a mission to scratch build all my Faireys at a scale of 1:12 as I'd already got a Huntress at that scale built by Dave Milbourn. Five underway and two more planned!

    As well as being too big for what I wanted I also wanted the superstructure to lift off as one to gain access to the motor and RC installation etc. So, I did my own drawings as per my other builds. The superstructure was fiddly as I wanted to keep the coamings thin, but I managed it.

    I'll post a list of all the Fairey kits on a separate thread.

    I've got the book of the 1969 Round Britain Powerboat Race as it featured a number of Faireys. And the story of Peter Twiss's world record - it was amazing it ever happened given the problems.

    On YouTube there is a video of the race called Ride the white horses 1969 which is worth a watch along with a number of others featuring Faireys.

    One of my first Fairey builds was a Huntress 28 and whilst the stained deck looks quite nice I didn't plank it like my later builds so I think I'm going to finish it as a race boat - got to have one in the fleet! The decks on those were usually painted.

    Thanks for the information on the boat.

    It's a pity that the Kingston Flyer doesn't run anymore, especially where the track used to be from Queenstown towards Southland. But I suppose fire is an issue nowadays.

    Is there any need to install fuses in all three motor wires for a brushless motor? Given the speed at which power is switched between each, wouldn't one fuse be sufficient?

    Only one is used in a brushed motor circuit.

    Couldn't help myself, here's a few of the scenery to further whet the appetite!

    First three are from our first visit in 2017. The rest are from around Queenstown on the last one. During the last couple of days it rained overnight and we were were lucky enough to wake up to some snow on the mountains, lovely.

    I dont currently ๐Ÿ˜Š fit fuses in my builds but may well do so in the future. I've read a number of threads on different forums previously about the subject and as said some do fit fuses and others don't, including very experienced modellers.

    In my case the risks are very low as I use good quality ESCs and motors, I don't run my boats hard and our lake is on private land (no rubbish) and the weed is kept well under control, but again as said, why take any risk if for a few ยฃs protection can be easily added?

    My only real concern is fire and if I fit a fuse it will be to combat that. I'm glad the wiring has been mentioned as I also think that is the weak link and the fuse should be based on that rather than the motor or other component. The problem for me is sizing the fuse. I use silicone cable from Component Shop and err on the side of safety sizewise but it is the cable fitted by the motor manufacturer that concerns me. If fitted with bullet connecters already and braided as are my Overlander motors it isn't easy to determine the size of the cable but one would hope they are sufficient for the max. current draw of the motor!

    I will use car type blade fuses but one thought I do have is that the cable entries use chocolate box type connecters which goes against my use of good quality connectors i.e. XT60 and bullet and is a reason I only want to use the minimum number of fuses.

    Thanks JB.

    Another photo of the Shotover jet showing the launch tractors on the gentler part of the run i.e. not through the narrow canyon!

    Also the other major operator, KJet with the yellow boats that start from the lake in Queenstown. This is a gentler ride, though the lake can get very choppy and then goes down the river for some distance. The inlaws said going through the bridge supports and dropping down into the river was a bit hairy though! There is also a third operator, Realnz - I didn't see many of their boats so I think they are quite small.

    Lastly, a photo of a nice motor sailer moored on the lake, which would make a nice model.

    I won't bore you with any more! I've got hundreds of photos to go through now and sort out of the stunning scenery etc. to give copies to the inlaws.

    Unfortunately not Bob! Have another niece there but she got married in the UK before emigrating. Likewise with a nephew in Oz.

    To be honest I don't really fancy the long flights again, unless I went business class, which is unlikely. Especially as we had problems at Dubai, for the second time due to weather conditions, which had a knock on effect with other connections and an additional flight. We were shattered by the time we got there. No problems on the way back but very tired due to little sleep. It's a long old haul but probably one of the reasons it remains unspoiled.

    As mentioned on another thread we've recently returned from another trip to NZ for another family wedding and holiday, the last being 7 years ago. Those that have been there and are lucky enough to live there know what a lovely place it is with stunning scenery.

    We toured all around NZ the first time, including spending time in Queenstown, but this time spent all the time in the area in different places, so was able to do all the boat things I wasn't able to do last time.

    First was a ride on a Shotover Jet fitted with twin Mercruiser V8s providing 700hp and driving Hamilton water-jets which sounded great. I enjoyed it but it was a bit of a white knuckle ride in places! The drivers are very skilled and miss the rocks by inches in the canyons! Should have done it last time when I was a more spritely 63! Or done the other one my in-laws did as well that started on the lake at Queenstown which they said was less frenetic.

    At the other end of the scale and much more sedate we did a couple of lake cruises. One a smaller boat taking us to one end of the lake and the other TSS Earnslaw, a steamer built in 1912, which took us part way towards the other end of the lake for lunch, it's a big lake!

    We had a great time, including meeting up with younger family members who have made their home there.

    That photo from the born again Fairey Marine site is the the only Swordsman with aft cabin that I've seen with the traditional rounded air-intakes. The original Fairey Marine with aft cabin was called the Super Swordsman and had the much larger, squarer intakes.

    Said I'd got the anorak! ๐Ÿ˜€

    You're a braver man than me!

    Mine are relatively new but I was still anxious before going away on a recent 4 week holiday. But after a careful inspection, checking the internal resistance and recharging to the storage voltage I was happy.

    Do bear in mind that even if OK, over time and number of charges their performance does decrease.

    Just got back from a second trip to New Zealand having been there 7 years ago. It's like a breathe of fresh air with being a similar size to the UK but a tenth of the population!

    Driving is a joy with great roads and little traffic once away from the few towns and cities. Didn't tour this time but stayed in the stunning Queenstown area in various locations which we visited last time. Did some boat related things I will mention elsewhere later.

    Les Rowell was founder of Lesro Models and chief designer at Aerokits and died in 1992.

    A number of well known kits were produced by Lesro including the Stiletto/Rapier and Arrow/Javelin, Sprite and Sportsman with the latter reintroduced in Mk 2 form by SLEC.

    The business was sold and you could obtain copies of the kit plans but but you can't do that anymore.
