Title: 1/4 scale Bluebird K7 for turbine power - new project started........
Post by: rapidrabbit on August 19, 2009, 09:32:32 pm
I though this may be of interest to someone and also the best place to post some details of my new project. It's a 1/4.3 scale Bluebird K7 hydroplane for gas turbine power.

Here are some pics of the build so far - These pictures are of the plug that I am constructing ready to make my moulds from. My actual boat will be constructed from composite materials.

Enlarged and printed out my plans.....................

Starting to take shape but now some serious sanding and finishing is required!  %

Going to need a larger table I think......... {-)

Be interested to hear some details on the gas turbine you intend to use.

Hi Rick,

The turbine I have at present puts out 20lbs of thrust, so as long as I can get the boat built at 20lbs or a little less then I will have 1-1 power to weight. This I believe is what Bluebird (Full size) had on tap.

The 1/6 scale turbine powered bluebird doing the rounds at the mo' is powered by a wren 54 turbine which puts out approx 14lbs of thrust - the boat weighs approx 14lbs from what I have read.

It all depends on the final weight of my build - which is some way off as yet but edging ever closer!  8)

Cheers,

Nigel  :-))

Wow that's nice i use the same technics to build my boats
It will look killer with carbon fiber 
I build fast electric

I use composites to cover it up
The removal of the foam the best way that works for me is acetone
 What is the way that you do?    :-)

That's a really great looking K-7, should be magnificent  on the water. Very keen to see the finished job. Does anyone know where I might find a set of plans for Malcolm Campbell's Bluebird K-4. Any help would be most appreciated.

Hi,


Long shot really but I think I have one of these completed 1:4.3 Bluebird K7 models and was hoping to get in touch with whoever constructed it


I am currently in the process of adding additional detail and setting up for RC and Jet power


Any information would be greatly appreciated

The post pre-dates Imageshack throwing a wobbly and changing everyone's pic references. I've had to spend AGES sorting all that lot out, and they never even said 'sorry'...........

So no way to recover the images then?  Would be really interested to see them as I am pretty sure the K7 I have was made from the same moulds


Also I notice the poster was guest so I presume no way to get in contact with them either  :((

Very doubtful. The original poster has to re-code the links in my experience.

There are as far as I am aware two gas turbine models in existence, one by Ernie Lazenby and one by the Walkinshaw brothers from South Shields, I belive there are clips on You Tube
