masalai's model movie

That square bit above the "canoe stern" is not above w/l. W/L comes up 4 of its 6 inch height. The "step area will be turned into the vertical section like where your shaft comes out. On the current model that will be near the bottom edge of that square "step" - the stern face. Or else that whole section will be lowered to sit the whole lot lower.

Does that make sense? I am pencil or model myself. You still want some info on rotary wing pilot training?

 

As I have been told a hundred times Surface props are for planing hulls.

Yes thats true but semi displacement can use them but the rear end must be more like a planing hull. The water must come clean off the hull and should be stable.

Any one can design a hull but you will come up to brick wall when it comes to surface drives.

Every manufacturer will tell you their system will work and then when you ask them for help they will say it was'nt correct for the boat.

If it does'nt work you are out on your own. If that happens you had better know what you will do with that.

You are putting a system onto an unknown boat. No one knows any answers.

 

In the Chamberlin C10 - see my gallery but no pics of that action, the water does come out clean but showed turbulence from the screw underneath else should be OK? as is flat like after a planning hull transom over 9 or so knots.

I am aware it must be smooth but is a little turbulence allowed from the canoe shape ending vertically? or a small vertical trim tab for auto-pilot use?

Lots of more work on models else go as was, deep screw!

 

To be honest with you a surface drive is sexy, however most people just dont understand them. They are amazing in so much as they are vibration free, this has to be experienced to be believed.

However even if you can make them work the props are expensive and makes experimentation limited. Your more likely to sell it being conventional.

Mine is wonderfully economical at 17 she uses 35 liters per hour total.

But needs 2 engines all the time and under 15 drops off the plane, I have nothing between 7 and 17.

One engine can give me 5 knots at tick over 800 RPM.

Do you think the footprint of the levi will go on your transom.

 

Or something like yours or whatever. I want to look at all options before finally committing on build. Thanks again Frosty. Rotary wing?

 

If I were you and you wanted surface I would make the props like mine and then not do a big tunnel rudder I would make two small blade types inside of the drives infront of the prop, but to the side. The rudders are huge and to be honest do nothing in a marina. They are also very heavy. There is no way you can manouver with one engine, but can do what you want with 2.

Look at the back of the Atlantic Challenger if you can find anything. This was a Sony design too.

The Sony design is agricultural, heavy and sorry to say ugly unless you can conceal it under a swim platform etc. You also dont need that exhaust stuff.

 

Ok point heeded, I had thought of the rudder move already. Geniuses think alike? I was trying to be "diplomatic" in open thread. Yes the weight was a bit scary.

I have to get drawing & cooking. Thanks.

 

although small water rimples the model cuts them with ease in your movie posted in the gallery a while ago
i'm curious to see some more waves but make sure you helper isnt trowing that big rock to close to the model

by the way, everybody try'd "more" on google and checked books? many give a very good good read, here one for you ;-)

 

Thanks Yipster,
Read it in the local library some time ago, reading the waves & their ancient woven charts does not translate very well & misses a lot in the detail they used to be able to "read".

It has been raining here and therefore not suitable for further testing. I was going to wire up an amp-meter and place the gps next to it. These sets of data will be recorded with the digital camera also taped/affixed to the roofless test boat.

Another factor is my 1996 ford laser 4 door has had a major electronic heart attack. Starts sometimes as normal but quickly develops massive problems by missing and loss of all useable power. Bugger!! everyone (mechanics & service centres) seems to be away enjoying their Xmas break. Such is life?

The waves were created by an 6m model of a battleship weighing some 400kg

 

Mas check all the underbonnet engine management conections.

If a sensor is malfunctioning by a loose contact its possible the engine is choking thinking it is cold.

Just undo spray WD and then re do all plugs you can see several times.

May work!!! If not it has to be plugged in.

 

Its one of those abortions, covered in "human protective plastic", cant even get to the spark plugs & the distributor is BOLTED not spring clips any more???????

I suspected shorts but all wiring seemed connected OK, some (spark-plug) leads should be replaced as 11 years unchanged, but only 60,000km (mum's car), & look quite grotty.

Fckin modern crap, wires from everything, then disappear into looms & come out somewhere???? & do what, Yes I figered some smartass computer stuff as mandatory.


Image of model warship is on "random pictures", along with a view from my office at home.

 

bugger, had car computer problems too, many mechanics had a look, changed a lot, till one leaned over a little black box richt up front next to the latch that had a loose earth

 

Yipster, did I miss something? was that quote to me?

"...by the way, everybody try'd "more" on google and checked books?..."

To ******* & other friends,
"I want you gone" a song to "W" by Laura Love also would be pleased with the departure or that insult to human intelligence. She quotes him inferring he wants "...to interview all the Alligators who made all the allegations about him..."

We got rid of our idjit, now your turn fellows of USA....

Prosperous new year to you all

 

I have now installed both Delftship & freeship using wine & drinking some too. It remains to be seen if they work & I can upload a file from this net (lots of demos' included I will wait for something relevant to "masalais model".... No hurry as I am still in the spirit of merriment.

Linux can do almost everything, I can & enjoy doing most of the rest...

 

Success, They both work (DelftShip & FreeShip) - what is the difference?

I have uploaded "green lantern" which loads & is nice to play with (don't dare save changes on that), & thanks to Rick Willoughby, who sent me a base model of my project to play with and learn the ropes.

This windy and wet weather is the perfect opportunity to play on the computer & learn to use the ....Ship software.

Then with boldness and a better understanding should attempt to start from scratch. Time to RTFM. Thanks All, Seasons best wishes!

Is there any other manuals (apart from the included pdf) that will give a dummy like me step by step procedures to set up from scratch my cat design
1. . underwater hull lines as a separate item, finishing about 10cm (4") above loaded waterline and with a lip outwards by about 5cm (2")
2. . the bridgedeck will be another item
3. . the outer hulls another item.
4. . all can be brought together and "glued" in position not to be removed but can still be added to & manipulated??????

How do I start a new drawing (set up to do the above - if not in the pdf manual). Back to reading.......
