When is the special being issued?

Cheque? I thought I was paying you in 2nd class stamps…..

Colin

They're not useable when cut in half, are they?
Ref folk fearing embarrassment etc, I'm reminded of Steven Fry's acid comment "Thank the Lord for Sainsbury's – they keep the riff-raff out of Waitrose".

Getting back to the original subject of this thread and based upon the comments of those who took the time and effort to take part I have fixed the subject and size of my next design.

The design will be a 900mm long planing hull with three options of superstructure allowing the model builder greater flexibility without having to build three different models.

The three options are Cabin Cruiser, Harbour Boat / Sports Fishing Boat, MTB

The hull design is complete and the prototype frame has been built.

Thank you to everyone who participated and I hope that the outline sketches shown above meet with their approval.

[Bob Abell 2Participant @bobabell2]

Nice set of options there, Mr T

l like the top version best………. When will the plans be ready, please?

Hope you don`t mind me mentioning, that the rudder looks rather twee?

Bob

[Paul TParticipant @pault84577]

Good Morning Captain Bob

The plans will be complete by Saturday but building the test prototypes will take a little longer.

The rudder is 30 x 25mm and the theoretical programme shows it to be sufficient for the hull however the builder will have the option of a twin engine / rudder combination.

Paul

[Bob Abell 2Participant @bobabell2]

Thank you, Mr T

I should have known better

I'm often surprised at the amazingly small size of galleon rudders……… with the rate of progress being a snails pace

i'm impressed with your skilful boat designs Mtr T and will no doubt be the future classics in years to come

Bob

[Paul TParticipant @pault84577]

Thank you Bob

I'm not sure about the MTB version every being built by anyone else due to it being a smaller scale compared to the usual Perkasa. But I am pleased with the other two superstructure types and I'm looking forward to building the prototypes.

The problem with building prototypes is making sure that any error is picked up and the drawing altered to reflect the change, it's to easy to get carried away with the build and absorb minor alterations without recording them. But having said that my proof reader wouldn't let anything get past her without 'drawing it to my attention'

Paul

[Ian GardnerParticipant @iangardner62867]

Good idea, having alternative superstructures, Paul. The MTB might suit many folk being a bit smaller as I seem to remember having read posts in the past about how to get a Perkasa going well.

Ian

[Paul TParticipant @pault84577]

Ian

According to the calculations the smaller Perkasa will show a decent turn of speed from a couple of basic 500s. I hadn't considered the advantage of the smaller size model being easier to get speed out of…..I feel a lot happier now.

Thank you

I am about to launch myself into the murky world of brushless motors as my cohort in crime, Dr Tim Fawcett, has decided that he wants to design a brushless speed controller. A model of this size would be an excellent test bed for the smaller motors – that's if I can resist building yet another Fairey boat! A Turnigy 2836/1200 and a 3536/1450 are winging their way from ROC as I write.

[Paul TParticipant @pault84577]

Dave

I imagine they would make a suitable test bed for these new fangled motors but being a luddite I wouldn't know one end of a brushless from the other.

I am curious about quality….are the brushless motors from ROC any better than their speed controllers?

Paul

[Dave MilbournParticipant @davemilbourn48782]

The motors are reputed to be first class (the business end has the shaft sticking out of it, BTW). The speed controllers are typically Chinese – a triumph of price over quality.

Dave, I hope that the new brushless ESC is simple to set up! They all seem to come with a veritable forest of options and need a program card to set up easily. All this bleeping is not to be bothered with at the pond size when doing it manually.

I suppose that you would not need to maby options for a boat one, but of course a Lipo/Nimh option would have to be included i suppose.

I took project 2 out the other Sunday as stated and the craft started to cut out on me towards the end of the session, until I ralised that it must be the ESC dropping power to the motor because it thought the batteries were below cell min voltage (although I had it set for minimum) and I was using Nimh types. It came back ok on minimal throttle, obviously the currend draw was dropping voltage just sufficiently to cut off.

The ESc buzzes the motor to produce tones on the Ecranoplan.. most odd..

We've rather hijacked Paul's thread, so I've sent you a PM.
Dave M

[Paul TParticipant @pault84577]

Dave

I don't mind the hijack in fact I am looking forward to hearing whether or not the brackets arrive with the motors.

Paul

[Dave MilbournParticipant @davemilbourn48782]

Tee hee.

[Colin BishopModerator @colinbishop34627]

You are just too easily LED Dave….

[Dave MilbournParticipant @davemilbourn48782]

Nuts to both of you. The LED lights are up and working – no buzzing, no 50Hz flicker, daylight quality etc, so titter and chide all you like. I know it's just envy……………………

DM

(and the pictures of the motors do show brackets and screws. Fingers crossed for three weeks while the DHL donkey does its job).

[Paul TParticipant @pault84577]

Dave

Its nice to see how motorvated you are just be careful that you don't get led up the garden path.

Paul

[Dave MilbournParticipant @davemilbourn48782]

Wot garden path??

(Tee double hee!!)

DM

[Colin BishopModerator @colinbishop34627]

Well, I suppose that's one method of launching a model boat… Do you have a JCB lurking behind the workshop to fish them out again?

Colin

[Dave MilbournParticipant @davemilbourn48782]

Yep – it's on the extreme RHS of the picture, just beyond the far window of the garage (behind the gate that isn't). Unfortunately the fishpond has also been a victim of Liz's redesign, so no alfresco boat launchings in future.
Now behave yourselves and get back to model boats, will you?

Nice driveway just make sure they compact that stone properly as Liz's Huntsman and trailer combo will be heavy.

[Paul TParticipant @pault84577]

The protype build is going well and so far everything fits perfectly. (touching wood)

Paul

[Paul TParticipant @pault84577]

Had a great day on the canal testing the prototype hull, the water was flat calm and the sun was beating down so much I got sunburn on my baldy head.

The hull was fitted with a single Johnson 500 running on 12v pushing a 30mm prop, the hull was very well behaved and responded quickly to the radio commands.

Back to the drawing board now to detail the different superstructures.

All in all its been a great day.
