Too Powerful Brushless ? by ChrisF Sub-Lieutenant   Posted: 18 days ago
Graham - don't tell me you ran the boat at anything like full throttle. If so, it wouldn't just be the prop shaft that you'd have to worry about! If you did it must have been virtually uncontrollable! I take it you bought the boat with the motor already in it? Whatever, it couldn't really have been a worse choice! With such a high kv and being an inrunner (if I've got the right motor) it's really meant for a lighter, race type boat running on 2S to keep the revs down to a reasonable level. As you now know, for your type of boat you need a kv around 1000 or even a bit less as torque is what you need and also go for an outrunner. 3S or 4S is fine and if it is too fast limit the amount of throttle. Without seeing photos it's impossible to say if your existing prop shaft is up to the job but as you've removed it anyway and if you don't mind the expense I'd change it for one of the Raboesch maintenance free ones. I'm using these for my builds and my Fairey Swordsman at 33 inches is a similar size and weight. These are rated for 10k. and 15k. rpm, I've gone for the latter and in 5mm shaft size to be on the safe side. I doubt that a shorter prop shaft will be feasible as usually the motor is already pretty low in the boat and a shorter shaft will increase the angle and you don't want it too steep. Also you would have to redrill the hole for the different angle. What dia. is the existing prop shaft? The other thing you need to consider is the prop. What are you running at the moment? A photo of the boat would be good. Chris

Hi Richard Great looking boat and sits very well in the water. Good turn and turning. Well done!!! Hope you have many a good years with the Swordsman. Canabus

Richard That looks perfect to me - no mods necessary. Alan

Hi Richard - can't see how to find the video. Chris OK, found it now. Looks really good and the work is a credit to you. Not stupidly fast and turns well. Nice one. I see you are still calling it a Swordsman or is that how the link works?

Richards 48" Swordsman by RNinMunich Fleet Admiral!   Posted: 24 days ago
Null problemo😊 that's what we're all here for exchange of tips and tricks, no one knows it all 😉 Just saw your vid and must say the result looks really great, hats off. 👍👍👍 Hope my Sea Scout upgrade performs as well! Happy boating, cheers Doug 😎

Can I thank everyone who has contributed to my build. I could not have completed this project without the knowledge freely shared on this website. Thank you one and all. Richard

Richards 48" Swordsman by rmwall107 Lieutenant   Posted: 24 days ago
Hi, I have just posted a video of the boat in action (sorry about the thumbs in shot). See what you think. Richard

Old fairey swordsman i bought off a friend as a project, First time on the water after a 14 month refurbisment.

Richards 48" Swordsman by pmdevlin Fleet Admiral!   Posted: 25 days ago
Its pretty much impossible to say with pictures, but some video would tell the story as to is the plane due to speed, or imbalance, at the end of the day its your model so if you are happy that is enough!👍

Richards 48" Swordsman by RNinMunich Fleet Admiral!   Posted: 25 days ago
Agreed ads 👍 Richard, she looks good 👍 so 'if it ain't broke don't fix it' 😉 On no account move the batts forward. But if you're not 'appy then, if anything, a tick further back. Cheers Doug 😎

Richards 48" Swordsman by ads90 Commander   Posted: 25 days ago
It looks perfectly good to me - when going at full tilt the lift looks just right and you would expect the bow to dip as the speed is reduced. I wouldn't bother moving the batteries myself.

Richards 48" Swordsman by rmwall107 Lieutenant   Posted: 25 days ago
Hi I have finally put the boat on the water😁. i think it looks good and have uploaded three photos (sorry about the quality) the first shows the boat at rest (it had blown a fuse😭) the bow is slightly down, the second photo is the boat at full speed i think this is ok, the third is at about half throttle the boat seems flatter than at full speed. i remember a post earlier in this thread regarding putting the batteries further forward they are currently in the back. I think it is ok but do you think it is worth experimenting. Thanks Richard

Fairey Huntsman & Swordsman by pmdevlin Fleet Admiral!   Posted: 1 month ago
I dont uses mixes, but do use exponential and rates (spektrum dx6i) with my twin screw brushless 4 foot fireboat. When at speed rates on, then it turns nicer, no roll, when going slow rates off so turns are sharper, if that makes sense. Mixing the throttles.. interesting not thought of that, but it will lose power/speed. We use mixing on planes for taxiing, particularly on water, but once airborne its off. My avatar has this as the cheapo motors just wont balance so it compensates for this on the water. With the boat its easier to control with rudder input. I like the thinking though!😁

Hi Rowen, we're not splitting hairs! Together we are getting to the roots👍 I had also noticed the slight differences in superstructure; especially the aft part and the bridge top/screen. But I noticed these variations also in the Danish and other variants. Didn't want to overload the post with these as I thought it was long enough already😲 Seems some variations were introduced depending on the base variant it was ordered as MTB or MGB (most of which still had at least two torpedoes!). Since the Brave class were apparently very expensive to produce (which is why only two were built not the planned six?) the later variants were based on a cheaper export version, 'Felicity' type I think they were called. They were a little smaller but with similar performance and firepower to the Braves, some with two Perseus turbines instead of two but most with three as in the Braves, and cheaper to build with wood on alu frames instead of all metal. Usually classed as FPBs or FACs depending on armament. Summary; The Perkasa was not a generic class but a specific four ship class for the RMN. Basis for the hulls and superstructure design was the same as the Braves and Felicity but some 'poetic license' was taken with subsequent export order with variations even within classes. Comparing available (to me) pics again I now tend to agree with you that the rounded bridge of the model is more like the Perkasa class than the box-like bridge of Swordsman. 😲 BTW: In 1971 the RMN Perkasas were upgraded with SS12 missiles so there's another interesting variant for the aficionados 😉 Credentials: was not in the RAF (but Dad was!), but I worked with the RMN and the Surabaya shipyard (and various other bidders) on the design of the COMMS systems for the replacements for the Perkasa class and then their replacements, up to the current NGPV-2 (New Generation Patrol Vessel-Batch 2). Interesting work and people. Also did some work on their new frigates and an auxiliary in the nineties. One thing I always did before embarking on such projects was to research the background of the navy involved, operational area and requirements and also the potential shipyard partners. Part of establishing confidence and rapport. 😉 Anyway - whatever; model-wise - if it looks right it probably is right! Main thing is fun planning, building and above all sailing, exchanges like this help us all a lot I believe. All the best Doug 😎

Hi Doug, Hate to split hairs, but am researching a Brave Borderer for my next project. In doing so can advise that although the BB and the Brave Swordsman were sister ships, they had different superstructures. Have no idea why. The Perkasa was different again, it resembles the BB but it has an enclosed wheel house in front of what looks like a BB superstructure. This extended portion can be seen on the pictures. Sorry, as R.A.F in Canada, to disagree with you! Enjoyed the rest of your post though, it helped explain some of the export derivatives of the Brave class which I could not otherwise pin down. Rowen
