BRUTUS MK 11

[Bob Abell 2Participant @bobabell2]

Should have gone to SpecSavers?

This rule has caught me out yet again!

Bob

[Bob Abell 2Participant @bobabell2]

Having studied the problem for a few hours, have decided the cure is not worth the aggro

It helps to have a short memory at times

What`s 3mm between friends anyway?

Bob

[Paul TParticipant @pault84577]

Bob

I am a little confused about your missing 3mm, the oblique angle of the photograph and lack of reference hasn't helped me decipher your problem.

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

it's quite simple….

Look at the numbers 10….11….12

The actual inch line is between the numbers……10 and 11, but for 12 inches, the inch line comes comes before 12, losing 1/4"

Just to make room for the hole at the end!

It's my fault, but it is easily misread

Bob

[Paul TParticipant @pault84577]

Bob

You are talking about the ruler.

I thought you had a problem with the stern of the boat and that the ruler was to demonstrate an incorrect measurement

Paul

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob. I see what you mean, and you are right. With a stern of that width, a few mm makes no difference reallyl

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you, Ashley for your kind words of encouragement

Normally, I can put things right with a bit of wood and filler etc, but the kinky keel is only thin ply and there's not much meat to play about with!

Will give it more thought this morning, I was thinking about masking the sharp edge with a capping strip etc

But you are right, I think I'll turn a blind eye to it and do the Nelson Touch……..I see no ships etc

Bob

[ashley needhamParticipant @ashleyneedham69188]

If I worried about a couple of mm here and there I would never finish any of my boats!

Ashley

[Bob Abell 2Participant @bobabell2]

Hi Ashley, you will be pleased to read that I have gotten over my little 3 mm tiff and now ploughing on with the build!

The problem with this very excellent design is that there is not a straight line to use as a reference…..That`s to be expected of a 2050 warship, I suppose?……….Got to keep those missiles guessing, eh?

Interesting question……

The prop shafts look about 10 degrees off the horizontal

The motors look quite cumbersome at 10 degrees, but they look very nice if horizontal?

Any comments out there?

Bob

[ashley needhamParticipant @ashleyneedham69188]

Apparently the reduction in radar image for modern warships is not only to make them less detectable at long range, but also to make the radar countermeasures more effective. By making the size of the radar return from the ship match the countermeasure return more closely it helps to confuse missile radars.

Chunky powerful motors Bob, would be better if they were a bit more in line to put less strain on the u/j??. Are you using single, or twin u/j??

Ashley

[Bob Abell 2Participant @bobabell2]

Thanks Ashley

Just bolting them to a nice flat 6mm ply base right now

And large enough to fit the Control Gear too

Will try the level motor idea first, just to see the effect, they should look more authentic being level?

I`m using just one U/J at the moment

Bob

[ashley needhamParticipant @ashleyneedham69188]

To be honest, probably with such a shallow angle it would not make much difference.

As I have said before Bob, it’s your model, if you like the look of flat motors…go ahead!

Ashley

[Paul TParticipant @pault84577]

Bob

I've been looking at the original drawings from MK1 and it might help to install a support section running the full length between the underside of the prop tubes and the inside of the hull, this would help prevent the potential for whipping from any imbalance in the drive train.

Paul

[Bob Abell 2Participant @bobabell2]

Hi Paul and Ashley

The motors are now mounted on a small sheet of 6mm plywood and just pushed into the hull and it lined a treat with the shaft ends

I like the big chunky motors BTW chaps……They look just right for the job

The motors have also lined up with the incline of the propshafts too…….Another stroke of luck again

Back on the job with a smile once more

Bob

[Paul TParticipant @pault84577]

Hello Bob

You are ripping along nicely, I liked your comment.

The motors have also lined up with the incline of the propshafts too…….Another stroke of luck again

That is remarkable, its almost as though they were designed to fit so smoothly

When do you plan to sail it?

Paul

[Bob Abell 2Participant @bobabell2]

" When do i plan to sail it ?………..No idea at the moment, old boy

But it could get wet in the bath in a few weeks?

There`s a lot to be done yet

Thanks for your kind comments, and Ashley too

Bob

[Paul TParticipant @pault84577]

Bob

It might look good in silver, as the model is mainly large flat areas you could use aluminium foil, it would be very impressive on the water.

Paul

[Bob Abell 2Participant @bobabell2]

Not a bad idea, but how would I glue it on?

Can we still get……Silver wall paper?

Having a look at the wiring layout now and having to scratch my head!

Slowly slowly catchy Monkey….etc

Bob

[ashley needhamParticipant @ashleyneedham69188]

Halfords Aluminium spray is very silvery.

Foils a nice idea, v difficult to glue on without it looking all wrinkly ?

Ashley

[Bob Abell 2Participant @bobabell2]

Thanks chaps

There's plenty of time before we jump in with both feet

Bob

[Bob Abell 2Participant @bobabell2]

Laid out the wiring, to sort out where the wires go

Any comments chaps?

Bob

[Bob Abell 2Participant @bobabell2]

So far so good…..ie…..No comments

Now then, is the component spacing OK?

"I only arsked"……( Bernard Breslaw )

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob. Couple of things. Are you going to use a Y-lead and control both motors the same, or are you going to use proportional motor control?

7.2V is not much for the 850 and it won t go as well as it will on 12V.

Spacing. With such a big hull available, as long as the batteries are placed to get the weight even either side, all you need then is to be able to move them fore and aft to get the best running trim? As for the rest, stick them wherever you fancy!

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you, Ashley

I`m using a stick for each motor

I think I`m stuck with the stick batteries……..At the moment anyway

12V Hey?…..I didn`t notice that……Will have a look round

Just hoping that Duckie has still got his

I`m a little disappointed that the old Fan Club is not here anymore?

Many thanks my mate

Bob
