Bluebird K7

Hi all, my first post so please be gentle with me.
I'm Wayne from Colne in Lancashire, I'm very new to the hobby.
I started building a brushless prop driven 1/12 scale Bluebird K7 late on last year, I'd got the plans from Canada & they were at best very poor. At first it was 1 step forwards & 2 steps back but I've progressed to the point where it's "alive", just the canopy to vacuum form & fit & it will be ready to paint. During the backwards steps I've also built a 1/24 scale K7 for my grandson, just the sponsons to fit then it will be ready for paint also.
I've managed to lay my hands on the Nexus K7 plans at 8.4/1, I figured go big or go home so I had them doubled in size so they are now at 4.2/1, I just can't afford to put a turbine in is so I'm planning to put a couple of 27cc tiger king engines in it. it's going to be an expensive build so I'm collecting "stuff" for the build.
I've managed to get hold of an old Dumas short stuff fibreglass kit that I'm going to build for my grandson & ive just got a bigger hull off eBay for £30.
Can anyone identify this hull?
Sorry for the long post!!!
Cheers

Hi Dave,
The 1/12 Bluebird is brushless (all running gear from PMB), as it's made from balsa, I've waterproofed everything with sanding sealer inside & out. To be honest I was planning on taking it to quiet stretches of the Leeds/Liverpool canal as I didn't think any scale model boat clubs would want anything to do with my boat, but I will have a look at what clubs there are locally.

The 1/4.2 will be IC powered, I want it to reach a scale speed of 300mph so if I can hit 75mph in the real world with it I'll be very happy. I hope if I can keep it light enough a couple of Tiger King S27 Evo's will get me there. I've emailed PMB as they don't have any stock at the moment, to see when they are due some in, but I've not received a reply yet. Plan is to buy 1 engine initially so I can plan the layout & while I'm carrying on with the build I was going to drop it into this eBay hull to see how it performs.
I have a couple of Enya 40ss motors, I'm going to try one in the Short Stuff & see how it goes.
I can't cope sitting at home watching the telly, I like to keep busy😎

Hi Dave,
That looks like a really nice piece of water!
I have a massive appreciation for the work, skills & dedication involved in building & running accurate scale models.
My fascination is with fast boats, K7 in particular & although the design is over 60 years old now, it's still a bit of a hooligan. it just didn't occur to me that someone with a boat like mine would be welcome amongst the scale community, at first scan through list of clubs there isn't anything on my doorstep, I'll have to increase my radius.
My skill levels are limited but as they say every day is a school day & I'm picking up new knowledge & skills as I go along.
The concern for me between IC & Brushless is on one hand add fuel & run for hours vs add batteries & run for minutes. 240+ amp esc's can cost the same as a half decent 30cc IC engine but to be honest for me the sound of electric motors is far more preferable to IC. I guess I need to take on as much advice as possible before I start splashing the cash. I'm certainly not pigheaded enough to ignore advice given, that's for sure.
I've seen a video on YouTube of a guy building an aeroplane fuselage without a mold, by creating a blue foam plug & fibreglassing over it, once the fibreglass has been smoothed & filled it is split to remove the foam core, he ended up with a large lightweight fuselage that only needed minor bracing to make it strong enough to fly. This idea really appealed to me so I went out today and bought a load of blue foam, I'll have a go at building the sponsons first & see how I get on...

I couldn't resist any longer, here is my 1/12 scale K7 alongside a ply sponson template for my 1/4.2 scale next project. I'm feeling giddy, I might start going to the gym...

I'd been trying not to measure it to be honest, it will be 1.8m long from the tips of the sponsons the end of the jet pipe, gulp...
I've roughly cut out the sponsons now, lots of sanding to do now👍
