BRAVO ZULU those men👍
FLEET// 😎

So far so very good Graham👍
Lovely work on the oars and associated fittings👍
"Having watched the video again, I think I need to add software to pulse stretch the output for the head turn servo so that it turns further left and right. "
After watching the vid I think you may need to do the same for the 'up / down' servos.
The maiden will be the 'proof of the pudding', but I'm not sure that Bill is dipping his oars in deep enough for the full thrust effect.😮
Cheers, Doug 😎

That was the second time it came loose within a year Nerys.
The dentist's assistant messed it up in the first place!
When I finally got to the dentist and he gave me a €30 bill I told him 'You must be joking!'
Cheers, Doug 😎

Go for it Pete👍
You know you'll regret it if you don't😉
And now you know you can build her in a variety of variants.
You could even build the different fittings for all the variants and have a 'New' model every time you sail her!😊
Cheers, Doug 😎

Hi Gerd,
Stimmt, aber-
Ich glaube wir haben dass ganz am Anfang diese Geschichte schon geklärt!

"yes I could have paralleled up the batteries but"
If I'm not very much mistaken, or the diagram is mislabelled, that is exactly what you have done Hillro!
Both positives are connected via the fuses and both negatives via your negative rail.
If you MUST do that then you have to make sure that both batteries are identical.
That doesn't mean just the lables!
It means that they both must have the same actual voltage and state of charge.
Otherwise the stronger will start to try and charge up the weakest, which can lead to some excessive current and associated heating 💥🔥😭
To prevent that Schottky power diodes should be inserted into the + leads of both batteries.
A simple and neat way to do that, if you don't want to do the soldering yourself, is the Parallel Connection Board from Action Electronics (Component Shop).

And yes, F3 and F4 are back to front😮

"the next time I loose a cap I'll just glue it back with ca glue....he panicked and said Nooooo!"
Don't see why Joe!
About six years ago I did just that, when a crown came loose on the very morning I was getting ready to drive to Strasbourg for the Christmas Fair and lights. Didn't kill me, and the crown didn't fall out😁 And yes, I did Dremel out some of the original cement.😉
The Strasbourg fair is said to be the world's original Christmas Fair. Well worth a visit.

Some sources say that CA glue was invented for / used by the military in Korea and Vietnam for closing wounds quickly after field surgery.
Don't remember seeing it on M.A.S.H. though.
I expect Klinger had flogged it🙄
Cheers, Doug 😎

Does depend a bit on which version you are modelling.
They were built to bolt on, practically overnight, whatever weapons etc she need for a particular role. MGB, MTB, Rescue Launch, Minelayer, Sub-Hunter, Harbour Defence.
The original Modular capability?
Good luck. Post a Build Blog, or at least some photos please👍

and here the originals...😉
JFK's boat from the 103 series and the restored 617.

Well done the Missus👍
I like a 'suggestive' lady with a sense of humour!😉😮

Looking forward to your controller detail - AND the vid of the trials.
Cheers, Doug 😎

Hi Cash,
I think Nerys may be right, either a Dory or a Wherry.
Although the Dory seems to be narrower at the stern than your boat.
See here, from a USN Ship's Boats publication.
https://maritime.org/doc/boatcat/cat-0008.htm
Boats of The US Navy.
https://maritime.org/doc/boatcat/index.htm#toc

Colour scheme seems to be generally white hull with mahogany cap rails and internal fittings.
See attached pic of a Maine Wherry.
https://cottrellboatbuilding.com/
As a small utility boat they have no mast and may not have had Jack Staffs, but with a little poetic license I think you should have a small staff at the stern for a Texas Navy Association flag. Or is that no longer politically correct in these crazy times?🙄
If not then a a USN flag.😐
Cheers, Doug😎

"She says I have too many and shudders when I bring in another into the house."
It could be worse Boatshed😮 See pic!
😎

So that's 'all white' then ED😉
How do you tell which wire is which?
Greetings to Jenny, your able third and fourth hand👍
Cheers, Doug😎

" Making my own is a learning exercise ...."
Back then it was a financial necessity SC!🤔
Nevertheless, it's good to see some younger folks these days following in our footsteps with the same kind of 'What if?' curiosity👍
More power to your soldering iron!
Cheers,
Doug 😎
Attached pics of one of my first attempts at an ESC, using the technology of the time some 35 years ago, adapted as as winch / crane driver for my destroyer.😎
Basic principles are still the same as back then, regardless of what frequency (27, 35, 40 Meg or 2.4Gig) or hopping protocol is used to in transmission:-
PWM/PPM decoder --> analogue/pulsed voltage output to servo / ESC.

Hi Kevin,
"I may have a go at removing and ordering a new one to solder in."
While you're at it order five!
You will probably need to replace all 4 in the ESC, they seldom go individually kaputt, and a fifth as reserve will not cost the earth😉
Depending on the design you may need two each of two types, check the type numbers printed on them😉
Cheers, Doug 😎

Hi Bill,
What may also be important is-
What else did you change / upgrade / rewire in the course of your refit?
Have you tried it on a simple Servo Tester?
Does it need to be 're-trained' from the TX for High / Neutral / Reverse?
Cheers, Doug😎

Hi Sc,
"What fun! One eason (sic) for a over current electronic protection is two fold."
Hmm! A two fold one 'eason'!
"A fuse will prevent a fire after the H bridge has overheated and blown up."
Hmm2!
The object of choosing the right fuse (or circuit breaker) in the first place is to prevent the 'H bridge' from overheating and blowing up. A quick blow fuse of suitable rating will accomplish that task very well. As you intimate, essentially a fuse is there (in domestic appliances at least) to prevent a fire in the power wiring, contrary to popular belief.
But for us boat modellers; insertion of a fuse below the max current rating of the motor and/or ESC (whichever is the lowest) also protects the motor and the ESC.
Have fun building your circuit though😊
I have built ESCs in the past, first using bipolar power transistors SN 3055s and a relay and then Darlingtons, and later FETs, N channel of course😉 due to the lower internal resisitance, but nowadays it's just not worth the time and effort. ESCs are much cheaper and versatile now than 30 - 40 years ago and I prefer now to invest the time in research of the original ship and the effort in the recreation as a scale model.

" Usually the ESC just cuts out and you are floating helplessly downstream. That is one reason I have just bought a tug.... "
When I purchase an ESC I look closely at the specs; max volts and amps OK, but then also I look at the Low volts function. I look for one that limits the motor current but does not stop dead!
Most of my ships are multi-screw anyway (with two exceptions), so with a bit of luck if one screw is jammed I can get home on the other, or in some case one or two of the remaining shafts.
With modern 2.4Gig sets with back channel telemetry you can also monitor the drive battery voltage on the TX.
Unfortunately not applicable to my 40Meg sets for submarines, but for such applications there are other Monitor and Fail Safe circuits available.
Please don't let me dampen your enthusiasm for re-inventing a wheel though.
Each to his own👍 Will be interesting to see your circuit design in a blog here.
Good luck🤞
Cheers, Doug 😎
PS. for unforeseen emergencies I also have a Southampton tug (and a large towel🙄) on hand😊
PPS I have recently tested a selection of ESCs for operation in a mini model using a central power supply of a single 3./V LiPo cell. The Graupner Micro Speed 4 performs very well. In fact down to 2.0V.

Hi SC,
"On my device I am adding a current limit/ cut out so a stalled motor or stuck propeller does not cause blowups. "
I use a similar device, it's called a fuse! 😉😁
I agree with Kevin, a blog of your ESC build would be of great interest and help to many members I'm sure👍
Cheers, Doug

Simply superb Mike ☀️☀️☀️
and a great inspiration ...

to send my miserable fleet on a last voyage with open sea cocks!!🤔
😁😎

" it has lasted a long time so I am happy with the boat, and the performance is stunning."
If that's the case Robert why risk burning her up with "a more beefy motor"?
Basic question is - Why does she need a new motor in the first place?
(Test/development engineer in me coming out again!🙄)
What's wrong with the original motor?
And would an identical replacement go the same way?
First find the cause and then consider the way forward!😉
Cheers, Doug 😎
PS: Some pics and dimensions of the boat would be helpful 👍

How the 'Other half' live(d) Nerys!🙄
Or the Forbes 500!?
😎

Many thanks Pete (Vielen Dank)👍
A3 in pdf format would be good, if it ain't tooo much trouble😉
If not A4 would do. PDF format is good cos it's easier to import into my CAD software for scaling and/or mods. I'll PM you if anything interesting pops up.
Looks like the 'next' issue of MB mag will be the one that they were planning for the June issue! Saw it in the Preview at the back end of the May issue, last one I received!
Cheers, Doug 😎

Very nice Nerys👍
But don't she have the wrong colour sails for a 'Green Dragon'?😉
"which I bought in Barcelona"
Natch! Doesn't EVERYONE go to Barcelona to buy their books on Round and Flat Bottom (😮) Dutch yachts?🙄
Hope you get to sail her very soon🤞
Cheers, Doug 😁😎
Pic shows Green Dragon in 1959 with Princess Beatrix aboard.

"De Groene Draeck (English: The Green Dragon) is a royal yacht of Beatrix of the Netherlands. It was named after the flagship of Piet Hein, a famous 17th century Dutch admiral.
De Groene Draeck is a traditional Dutch round bottomed sailing ship, built in 1957 in Amsterdam. She was offered by the Dutch people to the then Princess Beatrix for her 18th birthday.[1] Her sail number is therefore VA 18.
The ship is regularly used by the Royal Family for sailing. The ship is usually moored in Muiden. "

Good work Chris👍
I'm sure your Dad would approve and be proud of you.
Especially like the lighting, seldom seen or posted on these models👍
I guess the 'servo driven electro-mechanical speed controller' was something akin to the dear old Bob's Board?
Cheers, Doug 😎

FLEET SHORE TO SHIP BROADCAST/
SUBJECT: COMMAND STRUCTURE / PROMOTION BOARDS:
On reviewing my (🙄😁) command structure I note that we are now a bit light at the Lieutenant Commander level! Thus making it difficult to find suitable candidates for command appointments within our smaller units and assets.
I also note that we have several very promising looking Lieutenants.
So; Fingers out gentlemen. We know you have it in you and look forward to your contributions and favourable reports from your respective COs👍
BRAVO ZULU ladies and gentlemen for your exemplary conduct and service during the current crisis. Good Conduct medals all round👍
FLEET//😎

And hearty congratulations to Captain Mike on his fourth ring and a bit more egg on his hat👍
What took so long!? 😁
Cheers, FLEET// 😎

Then ...
Hope you have a good trip to Hungary without too many complications and
Üdvözlettel, hogy a jobbik fele Zsuzsa !
(Hope I haven't just insulted her Grandma or summat!!😮)
Maybe Zsuzsa will quarantine you in your new workshop? 😁😂🤣
Best wishes to you both.
Cheers, Doug 😎

Mornin' Pete, (It is here now - Just!)
Ref the MB free plans-
I would be most grateful👍
I'll let you know if one particularly interests me.
Do you have a scanner? A3? A4?

In essence I think that the MB platform that Stephen created here HAS evolved into a sort of Model Boats / Ships magazine.
The quality of many Build Blogs I see here, the thought that has obviously gone into presentation, photos and text, can hold it's own with anything I have seen in the UK and German model boats mags. Well done Shipmates☀️☀️☀️
We all tell out stories, solve problems and swap experiences and expertise, and many 'Guests/Recruits' hover on the sidelines and benefit from this.
Just like the commercial magazines we have a hardcore (if one can/dare use such a once harmless word these days😮) of contributors and bloggers.
But a HELLUVA LOTTA readers!! Possibly more than MB mag subscribers??
So we must be doing summat right, and I count you amongst the 'We'👍

All the best, stay safe.
Cheers, Doug 😎
