1/10 Spirit of australia.

[Richie the shipwright]

Im glad.. Hope you liked it. That batch has been matured for three years!! I even necked one myself the other night. WOO-HOO!!

Sorry for being a bit slow with the thread guys, been busy as with work. Have done a bit more on the spirit, flange for inner hatch is now done, and a bit more work on the main hatch. just need to make a windscreen, then ill start making a 1/10 ken! Im also considering a flood chamber in the rear of the boat, to get the bow up during launch. The bouyancy testing i did showed the back end is really bouyant. Everything will be further back in the hull than i expected. going to go with a jae rigger style drive setup, offset in driveline will only be abot half an inch, Better than no offset. More photos soon i promise! :-)

Sure it floats now, but once you install motor, batteries, esc, Ken etc etc ad nauseum it will not be so buoyant.
The flood chamber will remove much needed bouyancy, mate.
Trial without the flood chamber.
There are simpler ways to launch a wet nosed boat than filling it's bum with water.

When I return this pickaxe we can swap notes !

Sorry to poke a stick in your spokes doc... but in the photo i posted.... everything IS IN THE BOAT!! weight- 2.05 kgs. She is going to need a wet botty..... with cg set at 1 1/2- 2" behind sponson the bow is lower than i want.

[drwayne]

keep yer stick outa my spokes, ya daft wallaby .......

Ive had a few hydros that floated nose down bum up like a horse's hoof on brokeback mountain ...
A little trick to get their head above water before you give it all, is to offer a quick stab from the go finger to pop up the nose.
Then more go finger to keep it up once broken free
If balanced right, the ride will remain static under power.
Hydros in flight are more about aerodynamics than wetted areas, mate.

Buzz has/had a 7.5outboard PratherPirahna(?) that didnt float above , which performed super good.

[Richie the shipwright]

Yeah i hear what youre saying, Ive built a few that were nose heavy too. Theres a lot of boat forward of the sponsons with this one. The real boat was really messy until it got up on plane, so i kind of expect the model to be the same. At rest, the bow on the real boat sat higher, the sponson decks were slightly above the waterline. I want my model to sit the same way....and it does with the rear chamber almost full of water. This will drain out quickly, as soon as i hit the go button. Makes sense to me. Dont worry...the back end has PLENTY of bouyancy amigo!
Also for anyone interested, I got a response to an email i sent to ken and dave warby. Both impressed with the model, and kind enough to offer some advice, and answer a few questions. They confirmed the boats original cg location for me, and that the fastest she ever went was during tests using an afterburner. How does 402mph sound!!! He lit the burner at 200mph.... YEE HAAR!!! Also told me to keep them posted with the build, and offered further help if needed. Great guys!! Their new boat is having engine fitted this week and should be finished and ready for testing later this year. Bring it on!!! AUSSIEAUSSIEAUSSIE!!!!

That's showing the OZ spirit so close to Aussie Day :D
Well done on the build too mate!! Looking forward to seeing more of the build :)
402mph is crazy fast!! WOW!!

[Richie the shipwright]

HAPPY AUSTRALIA DAY TO ALL YOU PATRIOTIC AUSSIES!!! OI...OI...OI!!!!

A few pics of my yard ready for a good old aussie bbq. Sorry i cant invite you all... :-( :-(


Party safe everyone. :-)

[drwayne]

Noice !

[Richie the shipwright]

Few photos of some progress ive made. Think i have the layout of everything sorted, the cg is now where it should be. The base of the tailplane is now also the cover of the rear "flood chamber". I can also access inside of transom from here. Rudder pushrod will pass through this conmpartment in a sealed tube, to servo mounted near motor. Will test boat without flood chamber first, if all goes well ill leave it sealed up. Motor is offset as much as it can be while still keeping the stuffing tube in the rear shoe. As i said before... better than no offset!! Ready now to start gluing in mounts etc, dryfit hardware then get into some painting. The green lump of plasticine in the photos is my temporary lipo pack. (dont own any yet!) :-)

Hi Richie ,

You're doing a great job in replicating Ken Warbys " Spirit of Australia " , I believe we have much to inspire us as R/C modellers in Australia . When you look at such raceboats as " Gods Gift " , " Top Gun " , " Plus One " which have still to be replicated in this form . Though they don't come as reverent as " Spirit Of Australia "

It would be great to see more Australian members on OSE.COM consider the wealth of spectacular raceboats in Oz , and create a build thread on this site , displaying our own home grown crop !!!

Hi brad... Its funny you say that, I have been recently researching Australias hydroplane racing history. And im really glad i did!! Much history... even a few Jones designs! Already found a few boats that I really want to build. One lovely roundnose in particular... But its a secret....shhhhhh!
There are quite a few of us here at ose, its just a shame in australia that we're all so spread out. Scratch builders are an endangered species it seems, Be really great to kick up some vintage 1/10 scale rooster tails....OZ STYLE!! Curse you yankies for hogging all the scale racing fun!! :-)

Hi Richie ,

Nothing against the U.S.A , though I'm Dinky Die Ozzy !! .

I grew up waterskiing at Wisemens Ferry on the Hawkesbury River in Sydney , and In my late teens drove , which I later owned a BB Chev powered Sanger Drag Boat , so i have no interest in hotted up cars " its all about H2-O " for me , and have seen the great raceboats of modern times blast through the Wisemens Ferry Valley , leaving awesome memories of them in my mind . That's why I feel a connection with history in this regard ." Plus One " as you might know is a Jones Hulled Bridge To Bridge record holder from around 1985 , and has an amazing colour scheme .


Due to my study commitments I have been missing for a while , though I am member , and have a build thread going on OSE.COM titled " Dumas Hotshot .45 Build In Progress "

Currently my wife and I are in the last throws of renovating our rental property here in Broken Hill ( NSW ) , then after moving back to Western Sydney , I will race my build with the Model Boat Club of NSW .

I take it you live in Adelaide ?? , i have elderly cousins that live in a few suburbs down there including " Paradise " . Good luck with the build , it's a beautiful replica !!! . Let's hope it inspires more Ozzy replicas !!!

Mad max country! Not much water in broken hill... ya poor bugger! Yep windor gardens, 5 mins drive from paradise.

Not down on our american model boat brothers at all man, just jealous as hell of the standard of racing they have! Lucky buggers! I also owe a lot to joerg aka "Jfromjags" for some killer advice and imput he has given me for this build. (on rrr).

Sounds like you had an awsome place to grow up, I bet you miss those good old days mate.

Hope you get back near the water soon bud. Being away it for too long is just bad for the soul... :-)

[rcboatmanwithkids2880]

Hi Richie ,

Being in the last throws of renovating , I do feel the waterways of Sydney calling me back , though my interest in real boating have changed ( matured ?? Lol ) somewhat , in that I am ambitious to buy a Sailboat for my young family to enjoy the waterways of Sydney Harbour including Broken Bay . With my new career blossoming as I write this , due to my study into Workplace Health and Safety , I may have picked up a position with a National Organisation as a " Safety Officer " , so hopefully it comes to fruition , so I can get back to one of my passions in life , foremost being my beautiful wife Natasha and our young family ....

When it comes to F/E Racing appeal , It may be due to population of the U.S.A being over tenfold , so therefore personal pursuits seem to be more represented in society . Kind of like when our NZ brothers and sisters land , and see whole bunch more life here , as we are over tenfold of them. ( I Love NZ )


Back to what matters though Richie , your build of " Spirit Of Australia " is such a nice replica , I just wish as Australians Modellers we could buy an F/ E of it . About ten years ago , I emailed Ken Warbys son , regarding my admiration for his Father Ken , which I received a nice reply .

Keep up the fine effort mate , we have much to celebrate in Oz regarding our Raceboat history , and I am glad that you are enlightening the rest of the world through this forum. !!!

Thanks a lot Brad. My early boating was all sailboats, (Holdies,herons,and the odd sharpie) which eventually led me to my current trade. Been envolved with many keelboats and ocean racers since, a few that even raced through bass strait in the sydney hobart bluewater classic. (with my crazy brother on board!!) So I understand fully the call of the wind...However motor racing and powerboats were always a big interest, And modelling has always been an obssession of mine as well as a way to learn about all types of boats.
You never know, I may yet do a mould for the spirit, till then... heres one of my own design 1/2m yachts for a bit of sailing inspiration. (yes i have moulds) and my 24" aussie themed shovelnose hydro i built a few years back.
All the best for your new career man. :-)
