That`s some paint spec you chaps have concocted!……. Er……What is EzeKote and lightweight fibre glass ?

How about…….Solar film?

**LINK**

Solarfilm is for model aeroplanes only. It has been tried on boats and is not up to the job.

Suit yourself.

Thanks Dave

Very handy to have

Just had an idea!……..I know Solar film is for aircraft, and I didn't seriously suggest covering Brutus with it.

But……..For starters…..The superstructure and top deck could be!

Just think of the quality and intense colours that are available?

Worth a thought?

I wonder?…..Mmmmm

Bob

[Bob Abell 2Participant @bobabell2]

Further to my apparent crazy suggestion of using Solarfilm……

What if I built the superstructure……….Model aircraft style………Conventional Balsa structure?

Boy!…..Brutus would fly!

The same goes for the inserted deck section!

And get this!……..The waterline is only 40mm!………Yer like it now Dave….eh?….eh?…..eh?

I could cut out most of the hull sides, and Solar film the boat after all!……..WOWEE!

For a classy paint finish……You ain't seen nothin' yet!

Paul!……Paul!…..Gerrup and read this story with a WOW factor!!

Paul………….Snorrrrrrrrrrrrrrre

Sssshhhh…..Let him sleep…….Bob

For readers who've never heard of Solar film……It's a plastic film that shrink wraps to wooden surfaces, especially Balsa!. It shrinks as tight as a drum and the colours are breath taking!……Aren't they, Dave?

[Dave MilbournParticipant @davemilbourn48782]

I give up.

DM

[Bob Abell 2Participant @bobabell2]

You really disappoint me Dave!

You should have welcomed the idea with open arms!…..You wait till Mr Big wakes up!

I only hope you like Humble Pie?

I love eggs btw

Seriously…….I'm giving the idea some serious thought!

Will try a sample shortly…….What was it?………Deep glossy black with silver or chrome?

Hello Dave ,

It s the silly season ……………………Larry from a padded room,

[Bob Abell 2Participant @bobabell2]

That's enough lip from you, Whetton!

You are both wearing blinkers?

They laughed at the chap who thought up …..3D printers!

Anybody out there, who likes my suggestion?…………I do, Bob!………(Our Geoff)

Bob

[Bob Abell 2Participant @bobabell2]

I`m so pleased how things are shaping up, that I had to show Paul the latest of manufacture!

What do you reckon, Paul?

It would be very interesting, should one or two of you chaps out there, had a go at building this very unusual and exciting model

Bob

[Paul TParticipant @pault84577]

Good afternoon Captain

The build is looking very good with everything coming out as expected.

I have never used Solar Film but having read the technical specifications I doubt that the material is robust enough to withstand anything but the most gentle of handling.

Watching the build with baited breath.

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

I'll build the cabin out of balsa wood and decide later, the covering material

Covering the deck at the moment and is going on nicely

Capt B

[Paul TParticipant @pault84577]

Don't forget to fit the rudder support blocks and rudder shafts before you cover the rear deck

[Bob Abell 2Participant @bobabell2]

OK, Paul……….There`s a good chance of doing that!

Well, the motors have finally arrived and I`m looking at them in utter amazement……..495 Watts!

At the moment they are a complete mystery to me….Nicely made though!

Plus a picture of the decking, thus far

Bob

[Paul TParticipant @pault84577]

Dear all

It never ceases to amaze me how a slight change in camera angle can create an optical illusion, looking at Bobs photo above you can see the R/H side deck is nice and flat all the way back to midships but have a look at the L/H side deck….there is a distinct illusion of a curve.

I know that there isn't a curve but the illusion is very compelling

Paul

[Bob Abell 2Participant @bobabell2]

You had me worried there, Paul

The deck is flat up to Former 3

I want to build up the coaming from the inside of the designed deck opening. So that the coaming is 6mm high and the cabin straddles the coaming rail. The cabin then rests on the deck.

The cabin is still the same width as drawn

The loose front deck will be sunk in and rest on ledges inside the hull,

The cabin will rest on the deck along the sides, but will rest on the foredeck and rest on the rear roll top cover

Do you understand my proposal?

Bob

[Paul TParticipant @pault84577]

Bob

Yes I understand and I am all for it especially if it makes the build easier.

Paul

[Bob Abell 2Participant @bobabell2]

Made some progress today, developing the cabin structure……..What a picnic we`ve had!

The windscreen area follows the roof curve, but it is in fresh air at the moment

The deck top make be extended and go under the cabin…….Well that`s what I`ve come up with anyway!…..Paul is still scratching his head!

Bob

[Andy CParticipant @andyc56856]

I was talk to my local model shop the other week about paint boats, he mainly deals with planes, but he suggested a sort of two coat stuff (can't remember), that he uses on all his planes now. Looking at the finish you could see yourself in it, absolutely mirror like. Said it was very light, but also very tough.

I should go back and ask him what it was he uses. Will let you know, unless others might know what I am rambling about.

You cant beat a drop of Humbrol! it even wet`n`dry`s well after a period hardening. I would be in favour of Halfords spray paint to get a nice even finish to set off the slab sides …do they do a satin black?

I am concerned now looking at this build that when at rest or slow speed it will look just like A.N.Other slipper launch and the snazzy main feature (the wave-piercing bow) will be hidden and so lost.

An upturn or rise at the bow (on top of course) would make even more of an impact on the novel front design when viewed on the stand and also look that much different when on the water.A slight negative rake , even if only applied above the waterline would also add low speed impact (if you see what I mean..).?

If you are going to have a feature…have a feature and make it large.

Ashley

[Bob Abell 2Participant @bobabell2]

Hello Ashley

At the moment, it's almost a blank canvas, as you point out………Just crying out for something adding?

But you know Paul…….He's got his mind made up in concrete!

But, we can add anything we like……As long as it is easily removed!

For instance, you mentioned more AXE on the front?……We could easily add a Wave Breaker?…..In fact, I'll fit one this morning, for your approval……and if the Master likes it?….It can stay!

I would like a few large port holes somewhere…….Easy stick on feature

A pair of futuristic wing things at the back somewhere, might look nice?

A pair of aggressive looking air intakes will be useful on the front deck, as there is nothing to grip, when taking the deck off. Plus a pair of working exhaust pipes at the back, since we're talking 950 watts!

I like the idea, immensely!

Bob

PS…….How about a pair of SloMo working air rudders?

I'm Not worried about this.

I do see what you mean and my answer would be no.

 

Bob

No wave breaker the deck is intended to be completely flat and devoid of any structures.

I would like a few large port holes somewhere…….Easy stick on feature……….

No portholes its not a cabin cruiser, like the deck the hull is intended to be perfectly clean and devoid of any structures.

A pair of futuristic wing things at the back somewhere, might look nice?……….

Its not the batboat

Absolutely not as it would spoil the clean lines of the design

That`s ma boy!

What did I tell yer? Ashley……….He`s Adam Ant!

We`re only having a bit of fun, Paul

But when all the excitement has died down………?

Now then, Mr Designer………With 950 watts burning away inside……..What about cooling?

Bob on the shop, with fingers tapping

PS…..You`ve not commented on the cabin mockup?

PSS…How about a bank of louvres each side somewhere?

[Paul TParticipant @pault84577]

Bob

The cabin mock up looks just fine but the following detail will help the readers who might not know what we are talking about .

Regarding cooling the motors I don't know anything about these brushless thingies so you will have to tell me how much heat, if any, these motors generate.

I'm not a fan of louvers as they let more water in than warm air out but if those motors need fresh air then I will have to come up with something.

Paul

[ashley needhamParticipant @ashleyneedham69188]

Outrunners should not need cooling, but certainly there will need to be a free air movement (like ban the bomb) to assist. The ESC is likely to be watercooled and best put some waterscoops at the rear for this.

Bob does get carried away with the boat pimping but that`s youth for you.

I am older and thus more restrained..

Ashley

[Bob Abell 2Participant @bobabell2]

All those great ideas………Shot down in flames by Dr No!…………..Subtle name that…..Think about it

Paul, got a bit of an Enigma here!

The hull`s sweeping curve shape was obtained from the stringer slots in the formers, so the shape must be as drawn

The cabin profile was obtained from the side view, sheet 15 and yet the cabin roof line is nowhere near parallel to the fore deck………Why?

The cabin is already 8mm higher than it should be!

To bring the roof level, we need to cut the roof line, down at the back by 16mm!……eh?

Please look into this, please

How strange?…….Bob

 

PS……..Paul…..Got two prop shafts…..Only 230mm tube length……….Can we use them?

Not a problem if we can`t, they`ll probably be ok in the SloMo

Edited By Bob Abell on 07/02/2014 20:33:05

[ashley needhamParticipant @ashleyneedham69188]

Bob. REALLY need to think about water scoops behind the props before sticking that very low rear end on. I have small experience of high power craft, but this says that as soon as you start getting into the 20A+ current draw region, you start to need force cooling of the ESC`s.

Last picture,,,very swoopy! Dr No….like it. Just because he is designing it and you have agreed to follow the drawings he thinks he can call the shots…..
