Too Powerful Brushless ? by BOATSHED Admiral   Posted: 16 days ago
I was also told about cutting away the front edge for the same reason, digging in on turn's. I have found on hulls like the Vosper RAF Crash Tenders and MTB hulls they sit on the water on a turn as if they are stuck on the water no roll at all. Also on the Huntsman style hull they also turn a lot better with minimal roll. It was told to me on her the other day that the rudders were meant to be the way they are and there was no need to cut away the leading edge. I have done this for many years now, since the mid 70's and had great results I even put a 10cc engine in a hull rated for 5 to 7.5cc and it was an amazing boat to run. I turned a couple of boats upside down until the rudders were trimmed and then good to turn. I'm glad I have found someone that thinks it's alright to do. 👍😊

Too Powerful Brushless ? by pmdevlin Fleet Admiral!   Posted: 16 days ago
sorry to bore everyone with repeated info, as a similar question was posed recently. I agree with the fact that shaft is too thin, it very much looks llike a fibreglass very light racing boat set up, now this doesnt mean you cant go fast with your boat, but you need components that are up to lugging a big heavy lump of wood around the pond, not a lightweight feather😊 I have 5mm shafts, less whipping. and I have oilers so they are lubricated with oil rather than grease, just my preference. You can get these shafts from shg marine, they will supply with push in aceteal (probably spelt wrong!) water lubricated bearings, real cheap, so you can change then every season if you want. The shaft has to be supported, where it exits the hull, just put it through another piece of ply, and fill the void with epoxy, and double up the former thingy it goes through in the same way. (pic) The prop you used is the wrong blade type, thats probaly why it fell apart, plus the soldered on blades are a weak design for higher speed, simon higging is one piece, but at this stage, still testing, you can get plastic "x" blade ("s" blade are less speed)_ props again from shg marine for a few quid each, then you can test a few different sizes. If you jump in for an expensive brass one, and its wrong, its wasted money. As a starting point, 35mm, 40mm and 45mm, if you dont have any way of testing with data logging etc, you are doing short runs, with the smallest first, and seeing if the motor gets hot etc, and what sort of speed you are doing. My brushless motors are generally 800 to 900kv, and achieve 25mph in four foot heavy hulls, you want lower kv for torque, not high kv high rev motors. I got into thsi 10 years ago, thwere was NO advice around then as it was new tech in boats so I learnt the hard way😭 When (if) you go to a brass prop, the "cleaver" blade design (pic) works well, I did extensive testing with my Huntsman and fireboat and was lucky enough to have Simon Higgins testing props with me on my boats, again because what I was doing, large scale boats, but going very fast, was unique, and the cleaver design was the best at the time. Forget the fear of lipo, and brushless, they go as slow as your throttle stick is pushed, 👍

Hi I use 4mm stainless steel shaft with a brass or roller bearing at the motor end and a Teflon bearing at the bottom. Grease I use Dow Coring Molykote Compound 111. A squirt in each bearing and install the shaft with a finger over the inner bearing( the air escapes via the oiler tube) and cap off the oiler. I the picture is the shaft support on my Huntsman which is a slide fix for the prop shaft tube. Canabus

I always use as smaller rudder as I can get away with. I had been running model boats for many years then one day when on Blackheath pond someone was watching my boat and remarked on how it turned. badly, and I replied that's how it had always turned. The guy had a boat the same as mine it was a MFA Spearfish, He asked if he could swap rudders on my boat and try his on my boat so that's what I done and it performed much better on the water. I then tried it on my Vosper RAF Crash Tender and it just stuck to the water on any turn tight or wide. So I have done this ever since. On my Huntsman I had turned it over several times before trying this so I done the same on this and once again it was a lot better turning and didn't turn over. I don't like using large rudders if I cannot get one small enough for what I wan't I will get one and then cut it down. We used to race 5 or 6 boats on the water at a time and always needed to turn tight turns to get round the pond. Even watching Power Boat racing on the telly in the past they make tight turns to get round. I have a Probaot Miss Geico tunnel hull and straight from the box brand new the rudder on that has no leading edge and I can turn that flat out on the water with no roll at all. I suppose I am a speed freak and it has worked fine for me. Even if it is the wrong thing to do. The small avatar picture on my posts is a boat I have in Norfolk. This has a 1960 Volvo Penta outdrive probably one of the earliest one's made and that doesn't like to turn on 3/4 throttle without the engine revs dropping and digging in on a turn. I have tried this when out on open water up there. Don't try it now as got a warning from the Norfolk River Constabulary. Don't want to loose my river licence.

Hi All I am using Hobbyking 3639-1100 and 3648-1450kv motors in that size boats(Sea Commander, Precedent Huntsman and SG&K Gentleman's Runabout). 60 Amp ESC with either 3 or 4S Lipo batteries. Props 2 blade 40mm 1.4 or 1.6 pitch. The motors are a straight change over and the only change to the ESC is the low voltage setting for the 3S and 4S batteries. Canabus

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!😁

Are you going to let DENIS the Menace skipper your boat ? Don't let him damage.😉

In my Huntsman I have a T600 brushless.👍

31" Precedent Huntsman by Novagsi0 Captain   Posted: 2 months ago
Few fittings added and new battery ordered for the new year.

Hunstman 31 fittings kit for Christmas from Slec by Novagsi0 Captain   Posted: 2 months ago
Yes they do. Their model is tiny ,this is the precedent 31" huntsman. The fittings look the perfect scale. In my opinion there too big for their model.

motors by pilot Petty Officer   Posted: 2 months ago
hi just looking at some off my electric motors from my rc gliders and found a dymond gtx-4356v2/600kv outrunner. could i use this on my huntsman 31 if i can how would i cool it need to get this sorted

motors by ChrisF Sub-Lieutenant   Posted: 2 months ago
No, that's less powerful than in Pilot's opening post and like his suggestion is an inrunner motor. The consensus is that a 50 mm diameter outrunner ( the first part of the model No.) is what is required for a big boat like the Huntsman. The second part of the No. is the length of the motor. That size plus a kv figure of around 700 to 1000 will provide plenty of torque to get it moving and high enough revs to get it on the plane. Once you start getting a kv figure well over 1000 you start to get into higher revs which is useful for smaller batteries (e.g. 1000kv x 7.4v = 7400 rpm) which as said is good for fairly small, light, sports and race type boats. Conversely if you have quite a big displacement boat then you want quite a big motor but with a low kv figure as you don't generally want to tear along but want torque! Chris

motors by ChrisF Sub-Lieutenant   Posted: 2 months ago
The 46" Huntsman is a big old beast and I'd be looking at something different. You want good speed but not manic. The one you mention is an inrunner brushless which doesn't have as much torque size for size as an outrunner. If it was me (and it will be at some stage as I have a 46" Huntsman with an MFA 850 brushed motor in it) I'd be looking for a 50 diameter outrunner around 700kv which will give plenty of torque. There is a Turnigy just under that which might do. I'm building a 33" Swordsman and am fitting an Overlander Tornado Thumper V3 4250/06 800kv outrunner. It is probably a little oversize but my thinking is that the motor will have an easy time, run cooler and the battery (4S) will last longer. If it is too fast I'll limit the throttle. Better to be too big than too small in my book. Overlander do a 5045/10 720kw which should be good on 4S which could always be increased to 6S if necessary. See what others say though. Chris
