Looks amazing, first class job 👌

Its correct in every respect and its the correct texture too.
Every single part of the kit was drawn in 3D cad (123D Design) and produced on a Forms2 3D printer. Then everything was scaled down to 1/16th scale and thse are now available from Tony Bakewell, the new owner of Speedline Models. See facebook👍

Very smart, nice clean lines, an excellent job so far Alan 👍👍👍
Looking forward to seeing her 'animated' 😀
Cheers, Doug 😎

Its a lovely kit to start with of course. That helps a bit.
Adrian Gosling
PS You can still get one if you know where to look.😊

Not sure if my painting of the anthracite section is correct though..🤔🤔

Yes so far so good, painted the white today👍

Very nice model Alan. You must be very pleased with the results so far.
Peter.

Is this your model or photos of the real boat!!??, Stunning detail, what a modeller.

Hi Alan, absolutely love that boat especially the quality of all the fittings and the realistic image it projects, right down to every single nut bolt and washer.

Awesome work Alan44.
You should put her in your Harbour.
We would like to know a little more about her.

And it would be nice to know what other projects you are or have been working on.

Martin555.

Only the very best from Alan 😎
Glad to have found you 👍

Andy

I seem to remember warning you about that Graham 😮
Same for Ben and the smoke for his pipe I suspect 😮😭
Whatever, good to see at least Bill in action again 👍
😎

Hi Gary,

You might have something there! I think his expression probably has more to do with the threaded rod glued into his nether regions which attaches him to the thwart! 😂🤣

Graham93

I really like this and the mechanics for the realistic rowing action, not forgetting the really nice planking and fine detail on the boat. Upon looking at the expression on the rower's face, I was wondering if he suffers from Piles?

Fantastic.
A real talking piece and show stopper.
Another one of Graham's masterpieces.

Martin555.

That planked hull is a work of art, and can be appreciated for what it is and the work that went into it. Painting is for hiding mistakes and filler. Regards.

That is lovely. I built mine recently but opted for clear coat to make it interesting at shows. A picture from the maiden voyage

https://photos.smugmug.com/Billing-Boats-Hoga-tug-708/i-Dk9cvRm/0/c5e18fbf/X3/F9

I should have mentioned it has a gas-fired steam engine, and in order to obtain access the super-structure and the fish hold lifts off along with a large piece of the decking. Regards, Gary.

I like your boat a lot you have made a really good job of putting it together and it sails rather well also. But I am afraid that I must correct your comment if the fact it is a North Sea Drifter, and has never pulled a trawl net in its life to date. The nets were paid out over the side and could be a mile long in length, the net hung like a curtain with floats on the top, and the herring were caught by the gills and unable to escape. I also have the Mountfleet Danny Boy and will enclose a photo. Regards, Gary

Nice video Phil Thank's.

Martin555.

Lucky you built a strong boat Roger😁👍 She's running much better now and looks good. 100c will give you a truckload of power !! You can never have too much power👍😁

JB

Hi Roger,
You are learning well! A similar road to the one I travelled a couple of years ago.
Hard to see the fuse block on my Brave now, but here is one am assembling for my next project. Got my fuse blocks off Banggood, they offer both 4 and 6 fuse ones.
Used a 6 on the Brave as wanted a fuse per motor, currently using 30 A capacity. Should protect the 50 A ESCs. Bigger fuses and even re-settable ones can be fitted into the block if warranted.
The home made buss bar and battery connector are visible.
Hope this helps.
Rowen
100C should be more that adequate, mine is 30C. You should be able to drive a welder with it too!

Hi Ronan
Thanks for your input.
Its starting to make sense now.
I bit the bullitt and bought a lipo battery and charger. I ended with a spectrum smart 2200mhz,3s, 11.1v,100c.i had a choice of a 30c but thought it may not be man enough for 3 motors so looked at the 50c, but was out of stock, so i ended with the 100c it was the same price as the 50c anyway. The charger was a spectrum smart type to. This monitors the battery and hopefully does everything automatically.
Once again thanks for your help and encouragement
Roger

Hi
Thanks for your input. Little by little everthing makes sense. Its a steep leaning curve but i feel im getting there.
Thanks once more
Roger

Hi there
Thanks for your reply
I have 2 esc 1 for the centre and the other on a y joint to the outer motors.both quikrun 1060,s i will now proceed to fit 3 seperate 30 amp fuses to each motors power feed.thanks for your input
Roger

Sorry Roger, 😌
When we were discussing your motors and ESCs I should have emphasised that my observations referred to EACH motor.
A single fuse will not be enough for all three, or even two motors.
At max efficiency each motor draws around 15A which explains why the 20A fuse blew as soon as you pushed the throttle through the gate on the two outers!
Since the stall current of each motor is apparently 21A (and the motors are brushed) put a 20A fuse in the positive wire to each motor.
Then if one motor stalls, due to weeds etc, or even two, then you can limp home on the (hopefully) remaining motor(s).
Sorry about the confusion.
Ref ESCs: do you have one for the centre motor and one on a Y cable for the two outer motors?
Doug 😎
PS I'll have some comments on your 2200mhz battery tomorrow (later today🙄).
Gettin' late here! G'night all 😴💤💤💤

Even using a 30amp fuse, that's only 15amps per motor, which isn't much.
Maybe as RHBaker suggests, individual circuits for each motor, then you should only blow one fuse and still retain propulsion from the other two motors to be able to return to the bank and check over, before replacing the fuse.
ideally, an amp meter needs to be used, to see what the motors are drawing, then you'll know if the motors, controllers and fuses are within spec or not.

Will

Hi Roger,
That looks better! A little higher out of the water and goes well.
Tried to see how you had the motors wired up and what type of motor, but cannot recall a blog.
Anyway, check mine, there are several remarks on this very issue.
Wired each motor and ESC individually and then ended up at 40A with a glass tube style fuse in each circuit. Could still blow the occasional fuse.
Used the individual wiring concept as wanted to retain as much redundancy as possible in the event of a fuse/ESC or motor failure. Lake Ontario is quite large!
Was recommended to use auto blade fuses and am currently using 30A on each circuit. Seems to have fixed the problem.
Want to test fully but cannot get back on the water yet as under a lockdown order.
If you are trying to use one fuse to control more that one motor would imagine to chances of a fuse failure would be high.
Whatever the motor/ESC combination it takes similar power for similar performance. The centre screw video shows a plane much as mine.
Good luck,
Rowen

ssshhhh...it's just the cover repainted...

Looks very good, heat shrink??

Excellent that looks a lot more realistic.
Great work.

Martin555.

I suspected it was on the 3s in the video.
Thanks for that Doug.

Will

Hi Will,
The videos were all taken at stage 3. 'Now we're getting somewhere' with the 3S LiPo.
As depicted in the report there wasn't anything worth filming on either the 7.2V NiMh or the 7.4V 2S LiPo. Plod plod boring! I wasn't really surprised. I just wanted to know 😉
Cheers, Doug 😎

Doug, in this video, which battery were you using, the 3s?

Sea Scout 'Jessica' First sea trial, Ostpark Munich 25.05.18. Pt. 3

Thanks.
Will

Hi Peter, see my PT109 Refit thread for the current status of my PTB.
I had to completely strip the hull.
Hope to get it primed and painted, Pacific green, and start refitting the shafts this week. I'll be starting a new Build Blog for it soon. 😉
Spent today sanding the hull of my Danish fish cutter 😡
Two parallel restorations / conversions and two hulls to prime and paint now! 😲 Good luck and much success with your various builds and renovations, great shame about the local pond🤔 I'm mostly alone as well, I avoid the weekend crowds! Cheers, Doug 😎

So, that is where the 50Cal guns are supposed to be😁
Looks like a similar project to mine.
I could sail close by but I would be alone. The local club closed years ago and the pond they used is now a no go zone for boats.
The river at my house has no flow as such. it is a tributory of the Danube which has a barrier at each end. The total length, about 15 miles, is a nature reserve and the water level is adjusted to keep it constant.The ripples are caused by the wind. The flip was caused by a bad Captain......probably.😊

Thanks Peter 👍 I was quite pleased with the results😊
Yep swans can get a bit 'sniffy' when they have the youngsters with them.
At one stage he tried to bite my leg😲
It's worth the effort to get a really smooth paint job on the hull. I'm sure it helps give that little extra speed, and the water and muck just pearls off so it's dead easy to dry and clean afterwards 😉
I've always been wary of sailing on rivers. I have a nightmare of something failing and the boat being swept away by a current😲
I'm sure we'll manage to find a setup to give your PTB the necessary Oomph 😁 I have a 28" PTB due for a clean up and refit / repaint as PT109. it has 2x28xx brushless fitted but I have no idea of their origin or power! I bought it last year from another guy on this site. Looks like being my next refit job😉
Re: 'flipping' you have to be very careful you don't broach (go broadside on to the waves) !! Especially at speed on the plane.
Don't you have any sailing possibility nearer to home???
Cheers, Doug 😎

She looks super Doug. The Swan didn`t look too impressed though. I hope my PTB performs like that. Hope I can do a paint job like that as well.
Really nice test lake. I am concerned that my river might be a little choppy at times. I managed to totally flip the Genesis during the trials.
Great first trial.😊

Interesting Canabus! Not quite what you recommended last year 😲 if you now think the Propdrive 1000kV has "no guts" why did you recommend it to me?? Thanks for spoiling my mood 🤔 As far as I'm concerned you just devalued your currency!
I'm happy with her as she is, balance and stability is OK and performance, endurance vs current drain is much more lively than she ever was in 55 years.😊
After all, she's supposed to be a Broads Cruiser and not an Offshore Power Boat.😉 I'm not into racing either.
From time to time I'll fiddle with fittings detail and cockpit on Jessica.
Time to get on with other projects now. Doug 😎

Hi All
Looking at the boat and the specs, a few things jump out at me.
The battery is far to big and heavy for the boat(a 3S 2000-2650 mah).
The motor no guts( a Prop Drive V2 2836-1800kv).
The prop 2 blade 30-32mm.

Hope this helps, sorry to upset your setup.

Canabus

Thanks Donnie, hope my results help others who are treading similar paths 😉 Forgot to mention: after each run I 'tested' the motor temp with my fingertips - very slightly warm to the touch but nothing to get excited about so no need for cooling arrangements 😊

'Jessica is running really good.Thanks for putting all the info in the post.I'm sure it will be a lot of help to other modellers.Especially me.Good job on the restoration.

That's like what my Dad always told me: 'Practice the hard parts'.
On the other hand: the fish cutter is a long term full restoration😱
and I would dearly love to finally see the Belfast and/or Graf Spee on the water. Both together would be great, they are both around 1.3m LoA!!
Then there's the Akula II and HMS Manxman new builds😲 I must be nuts 😉
I think I'll tackle it this way-
The fish cutter as a longish term project from time to time while I'm refitting the Belfast and Graf Spee which 'only' need internal work.
Akula and Manxman can wait to next winter!
We'll see, I will be updating my 'Harbour' and 'Build Blogs' as appropriate.
When do we get to see Sea Trials of the 'Brooklyn' ? 😉

I would start on the hardest project first! Then work my way to the easiest one! Maybe this will work! it does for me...

You're Sooo right Ed👍
Especially if yours is the only 'show' on the water, like today. You meet some nice people 👍 Since I retired I can avoid the weekends and holidays when the Biergarten lake is overrun and overcrowded😊
Re: finding the time! You should see the state of my maisonette!! Or maybe not 😲 No wonder no woman lives with me for long 😉
Photos attached of possible next projects - What should I do next???
Answers on a postcard please to ..... 😁
1 The Danish fish cutter? Full restoration,
2 The ELCO PTB? Renovation, repaint and refit as PT-109,
3 Or maybe the cruiser HMS Belfast? Needs new props and RX and ESCs fitted.
4 KMS Graf Spee, needs new shafts, props, RX and ESCs.
Help! 😲
it's all go folks! Happy boating all, cheers Doug 😎

You've got quite a few projects ahead of you!
Where do you find the time? Can't wait to see the other boats also!
I find you bring a model to the water. People are just mesmerized, especially the children!

Muchas gracias Ed 👍, was worth all the effort. During one run a nice American lady showed up with her grandchildren who were quite absorbed with the boat's antics. We had quite a nice long chat. Was a good afternoon.
Now considering what's next (apart from final fittings and cockpit outfit for the Sea Scout): the old fish cutter restoration with my modified Taycol motor or the upgrade / conversion to PT-109 of the 1:35 ELCO PTB I bought last year !? Cheers Doug 😎

Great job on the sea trials! She looks perfect on the water!👍

Thanks Ron, must say I was very happy with the performance.
Was a good afternoon out 😁
Now to finish off the fixtures and fittings! And fit SPRAY RAILS!!
Many thanks also once again to Canabus of Hobart, Tasmania for recommending that motor and prop combo to me👍👍
JFF I also bought a 3500kV motor. Reckon if I fit that and run on 3S it'll rip the shaft out 😲 Have to find another boat to fit that in 😁
BTW: the 'Daddy' swan in the last scene chased me out to the middle of the lake and also tried to bite my leg!!!

Nice one Doug 👍 she sits up on the plane nicely and no nose diving under slower speeds got the balance perfectly set.

Mia culpa JB 😔
😎

Hi JB,
That makes prefect sense to me especially with the medication i am on LOL!!
Book me a flight!

Re Dilithium crystals, quite simple Doug (description)-

Dilithium is depicted as an extremely hard crystalline mineral that occurs naturally on some planets. It is believed that this material exists in more than three dimensions at the same time and this is somehow related to its properties. When placed in a high-frequency electromagnetic field, eddy currents are induced in its structure which keep charged particles away from the crystal lattice. This prevents it from reacting with antimatter when so energized, because the antimatter particles never actually touch it. Therefore, it is used to contain and regulate the annihilation reaction of matter and antimatter in a starship's warp core, which otherwise would explode from the uncontrolled annihilation reaction. Though low-quality artificial crystals can be grown or replicated, they are limited in the power of the reaction they can regulate without fragmenting, and are therefore largely unsuitable for warp drive applications. Due to the need for natural dilithium crystals for interstellar travel, deposits of this material are, much like real-world equivalents such as oil, a highly contested resource, and as such, dilithium crystals have led to more interstellar conflict than all other reasons combined.

I've booked a flight on Starship One to pick some up next week LOL (sorry Roger, it's all Dougs fault !)😁

JB

"(although harnessing the space - time continuum and introducing a quantum geodesic reverse gamma discharge system might do the trick)"
But where are you gonna get the Dilithium crystals from 'Scotty'? 😁😂
😎

Re KVA , what KVA Doug😂?? comes from chopping trees all day and trying to type stuff at around 6AM without having been to bed😁 Duly noted and corrected sir (although harnessing the space - time continuum and introducing a quantum geodesic reverse gamma discharge system might do the trick) LOL

JB

hi there
great info
I`ll read and digest
roger

Sorry, JBKIWI suggested the charger.

Hi Roger,
Does look a little low, but grand nevertheless!
The bigger issue is a lack of power to lift her onto a plane.
There are a number of comments from our electrical gurus with some great suggestions on how to tackle this.
I would not hesitate to use LI-POs (suggest 3S as that is what is in mine).
If they are looked after and used per recommendations nothing compares for power/weight.
You will require a good balance charger and see Doug has suggested one. I bought one of those recently (with the integral mains adapter) and am very pleased with it.
Rowen

I agree with most of what you say JB👍
Especially re LiPos and chargers 👍👍

Rogal,
Seems I might have got mixed up with another query I was answering on a different (brushless) motor configuration ref the current consumption. Sorry 😔 That's where I musta got the 90A from.
How'd I get into that - must take more water with the whusky!
But I could have sworn you wrote 12V/12Amp! Have you been doing some sneaky editing? 😉
Attached is the Mtroniks spec of your M600 motor.
Theoretically the M600 should draw around 5.19A @ 12V for 12000rpm at maximum efficiency which is only 59%. Not the best 🤔
5.19A x 12V = 62.28W. 59% of which is 36.7W, where the ~40W spec comes from.
Stall current is given as 21A so fit a 20 Amp fuse.
No figures are published for running on 6V, but I suspect that they would be pretty ropey.

Nevertheless, try the two NiMh packs (Hi current variety), providing 12V and I believe you will be pleasantly surprised. Two 6000mAh packs should give you about 1 to 1 1/2 hours run time. And you won't need to buy a Quicrun 1080 😀
If you use two 2S LiPo packs in series (= 14.8V), for the weight / power density advantage, you may need to set your TX throttle control to Max 90% (probably 'End Travel' in the TX programming) to prevent overdriving the motor.
JB is spot on re LiPos and chargers👍 Follow the simple rules and you'll be OK Rogal.
I've been using them for four years or so without burning down the house, or incinerating a model😊. The days of exploding phones and burning Dream Liners are long gone.
The charger I use is the Graupner Polaron.

https://www.graupner.com/Polaron-PRO-1CH500W-14S-2CH30W-NiMh-NiCd-3-Color-and-To

Aha! Every 'picture' tells a story Rogal!
I'm sure I read 12V/12Amp in your earlier post!?
Your motors are rated for 7.2V to 18V, with optimum performance / efficiency at 12V.
So with a 6V battery your motors are underfed, in fact they are starving🤔 When you go pedal to the metal that battery will maybe dive to 5V or less. It just ain't man enough for the job.
Go for the pair of 6V NiMh in series and everything should be hunkydory 👍 Even a 6V 12Ah SLA is probably gonna be around 2.5+kg .
Cheers, Doug 😎

Hi Roger, boat looks good but sounds like it's wanting more power. I'd change to LiPos (say 3s 2200mAh) as they are much lighter and have much better starting power than most similar voltage batteries and hold their power well. Your motors are only about 1250 KV (revs per volt) so will need to be spinning at about 10-12000 and stay at that level to have decent lasting thrust and speed, and LiPos are really suited for this requirement. You could use a 2s 2200 mAh LiPo on your centre motor and a 3s for your outers (I'm assuming you have 2 ESCs)

Your motors should only draw about 3.3A at 12v each(according to Dougs' spec info) -free running,-(in the water, maybe 8A max,- you'll need a watt meter between your battery and ESC to check this properly so you can get an accurate figure- this will show you which way you need to go,-prop/voltage wise) anything else is a guess.

If the motors are pulling say 20A and the ESC is getting warm (no problem as long as you can hold you finger on it) you can screw a small 12v fan onto the cooling fins to help cool it, and join it into your battery feed at a convenient spot (I solder a JST plug just behind the ESC- battery plug) so it can be un-plugged. You can also run it to a switch, (manual or electronic)

As Doug said, you will need a LiPo charger if you change to LiPos, but once you get the hang of LiPos I'm sure you won't go back. The easiest and most common charger is an I-MAX B6 (only a genuine one not a copy) which is fine for smaller batteries. You can also buy chargers which require no setting, specially for 2-3s batteries, which have no fancy settings to confuse you, they do nothing but balance charge, (I've used one for about 10years no problems, -they will also stop if they detect a dud cell)


The advantage of the better chargers is that they can charge, discharge, balance charge or storage charge. They also have a display so you can monitor what's happening,- fail-safes such as incorrect connection, wrong battery selected, battery temp sensors etc which let you know during setting up and charging. They also can charge different battery types, (LiPos, NiMh, li-on, NiCads etc.

Set function and B6 multi function charger examples shown. Tons of info everywhere if you decide to go the LiPo way. Nothing to be worried about if you are careful (driving a car's more dangerous😁)

JB

i think i must have given wrong info somewhere my battery is only 6volt 12amp
Roger

"But its like my "Ferrari" the power is there if you want it."
What scale is the Ferrari Rogal? 😉
I still like the Dino 😋
But my all time favourite is still my Lamborghini Countach 😋😋😋
Bright Canary yellow ....
.

.
.
.
HO scale Corgi! 😁😂🤣 😭
But with suspension and steering - so there!! 😜

"I like it, that is the sort of speed that gives the onlooker chance to see it and it is not just a blur."
You'll just have to get a faster pair o specs Martin 🤓
😁😂🤣
OKOK Only just got in from shopping - but I'll get my coat, yet again 🤔
You out there Rob?
😎

My pleasure Rogal 😀
Just another case of 'bin there dun that' 🤔 'changed it'! 😀
Like so many other guys (and Nerys-ies 😉) on this site.
Good luck with the mods🤞
BTW "I thought at the time it was battery drain from giving it full power. "
You might be right, a combination of ESC and battery reaction.
A fully charged 12V SLA will read 13.6V. The sudden almost 90A demand of all three motors on full chat probably caused the SLA to dip to 11 to 12V! They don't like surge current.
(And before anyone asks; car batteries have many more plates per cell and much thicker plates to cope with the high starter current.😉)
Cheers, Doug 😎

Hi Martin
Yes I agree with you, I didn't want to, as most members, as have I, have tugs for towing comps and scale steering models. I don't think it would go down too well racing around at full chat. But its like my "Ferrari" the power is there if you want it. LOL. I wish.
Regards Roger

Hi Doug
Excellent feedback, thankyou so much it must have took a while to type that reply. I am so grateful.
A point you make about the 1060 running both outer motors, got me thinking. yesterday at the pond I was running on the centre motor and then gave it full power on the two outers, she picked her bow up momentarily and then dipped ever so slightly. thinking about it now this could have been the temperature protection kicking in, it felt as if something had checked the top speed slightly. I thought at the time it was battery drain from giving it full power.
The props by the way are 35mm x 3blades
I have also disconnected a red wire, this was a query the site resolved last year at the time of fitting the esc`s.
So one partial solution to start with is probably to upgrade to a"1080" esc and definitely change battery type.
things are looking good, thankyou for your comments, I will certainly be working on them in the coming weeks
Roger

Hi Roger,
I like it, that is the sort of speed that gives the onlooker chance to see it and it is not just a blur.

Martin555.

Hi Rogal,
It's not the 12V that is the problem - your motors are rated for best performance at 12V 👍
No, it's the 12Ah. That means a weight of nearly 4kg 😮 as I know from experience with my 1.35m 1/72 scale destroyer - big fat lead brick weighing things down🤔 Had to adjust and repaint the water line and raise the gunnels! That was 35 years ago - now she has a pair of 2S LiPos with two 6 cell NiMh in reserve.
Here's a typical 12Ah SLA, probably the same format and weight as yours-

https://www.battery-direct.com/Battery-BP12-12.html

hi Doug
Thanks for your comments
The battery is 6v /12Ah, Is this the problem. Should i be using 12V?
the esc is quicrun 1060 brushed, 60amp x2, 1 for the 2 outer motors and 1 for the centre.
their spec states Input: 2-3S LiPo/6-9 Cells NiMH
BEC Output: Linear Mode:6V/3A, sorry for being a novice, what does this mean,
I was also under the impression that you could not use lipo with brushed motor only brushless and then i would need another type of esp. this is why i have gone down my present route, it was easier to understand and not as expensive,(well so i thought), if i can use lipo or niMH this may be the simple solution, if my grasp of what you are suggesting is correct.
Roger

So far so good Rogal 👍
"she sits a little low in the water,"
" when power was added to the outer screws I would say she didn't plane well as she wasn't going fast enough. even with all props on full power, I think also she is to heavy and the battery too far forward."
Rogal, I think the first thing I would do is to relegate the SLA to powering a lakeside DC charger 😉 and replace it with NiMh (or even better LiPos if you are happy with them).
Apart from the weight SLAs don't much like delivering the high currents that NiMh and LiPos can so the voltage drops off faster. What voltage is the SLA, 12V? Capacity (Ah)?

If so I would fit two 5 cell NiMh packs, one each side of the hull to help with trimming and any roll damping necessary.
For similar volts and capacity the NiMh will be lighter, helping with top speed and lifting her backside up a bit 😮🙈
What make / model are those 600 motors? DON'T WORRY! I just found it - Mtroniks, 15000rpm @ 12V. But only about 40W!
Cheers, Doug 😎

Excellent work😁

Looking good

Sounds like you could be right Doug.

Martin555.

Top job Roger,👍👍 looking forward to the 'sea trials'

JB

I have always loved the look of the Braves. I built a plastic version back in the 70's. You have done a wonderful job. Now we need to see her in her element. Pictures Please!!!

"the shark ate it Martin!! "
Aha! The next 'Orca' ??? 👍
😎

Excellent job Rogal 👍👍👍
I especially like the details, such as the well stocked flag locker 😀
Can we have a look inside please? 😉
Cheers, Doug 😎

the shark ate it Martin!!

You have done a great job there Rogal.
I am looking forward to seeing her in the wet stuff.

Any hint as to the next project ?

Martin555.

Nice model, Tom 👍

Very nice looking model tamarack 👍
