Bluebird k-7
Hello all! Before my two week sojourn out to California starting tomorrow...
Here she is, all 31 inches and 4.8 pounds of 3D printed 1/10th scale madness. And the questions are starting arise after more than a few hours spent in research. How to get her to plane even close to scale?
1) EDF? Probably not, actually I don't think even a 90mm fan, (which will, in fact, push a faomy jet) will ever get this boat to plane.
2) Prop? Maybe with dual 6s and a killer motor, monster cooling etc. But, nowhere near scale with a big prop hanging out the back.
3) Turbine? probably yes, but way out of my league in mechanicals and $$. There will be tons of head-scratching my quickly balding head on this experiment.
This is going to go on the shelf for the long haul as my freighter needs finishing and the big Sterling Chris Craft Corvette is screaming at me. But, off to Cali for now...I will drop some pix from time to time of our travels.
Best to all!

Half Hull side project.
To keep myself occupied while I gather the necessary equipment to jump into my Robbe Topkapi I had the great luck to win this half hull in an auction in Rhode Island and plan on restoring it. It's an old yacht showroom sales demo (note the hook eye), but with a nice history. It's a Pearson Triton 28 designed by legendary designer Carl Alberg in 1958 for the (now defunct) Pearson Yachts (Portsmouth, RI) and was one of the earliest (if not the first) commercially available mass produced fiberglass sailboats. Jouet in France licensed the design for European sales. Over 700 were built up until 1968.
I am going to clean it up, copy the lines, and mount it on a plaque. I have a fascination with half hulls. Down the road I am going to build a cutaway off the lines with an interior. Add it to the list!

Naxos Laser sheets
I am finally just getting going on the "short kit" of the Naxos fishing boat from China. I call it "short" because there are no instructions (posted somewhere on the web) and only a minimal amount of parts, but the fiberglass hull is beautiful. And the laser cut pilot house and deck parts (what there is of them) are really really sweet. However, a huge amount of kit-bashing is in the offing on this one!
As a side note, on a personal level. I am heading on a cross-country trip for a few weeks and it is always my habit to leave a project undone so I have something to look forward to when I get back. Call it habit or superstition...it's just me.

Running light colors?
Hey my Friends!
I have some running light questions for my Caltex Lumba-Lumba.
These I have covered....
Port = Red
Starboard =Green
But, I am not sure about these:
Aft Running Light = ?
Mast Running Light = ?
Mast Light = ?
Masthead Top Light = ?
As per usual your input is deeply appreciated.
Merry Christmas!!!!! -- Guy

Iโm with Roy. A 540 with a 6 cell Nicad is always a great reliable go-to method of propulsion. I never toss out my Nicads or any 540 that could be repurposed for good cruising in another build.

Thanks JB. These notes are a huge help! I will do my best to get the inlets to the fan as short as possible. I suspect that any sort of speed runs will be held to a minimum due to battery usage, not to mention the excessive heat. I recently saw a demonstration video of a guy bench testing a hi-speed LiPo brushless set up until it burned up. It didnโt take too long. Yikes!!!

Yessir Ed, thanks for forwarding this to me!
I have the 1:24 Speedline kit and was going to set-up for scale display, but then stumbled onto the large printed one and put it in mothballs...for now.
I will eventually experiment with a fan, but I am unsure that it will work. Much more research to do.

John!
What a beautiful build and incredibly helpful information on the inlets and fan area!
I truth be told I wish someone had come up with a traditional lightweight build kit of the K7, so I do appreciate your efforts to build from the ground up. This 3D print is light years away from what I normally do, but the printing was too much for me not to try after my Touchwood was destroyed.
I will hold onto the EDF fan plan for now in order to make proper intake tunnels. But first I wiLL endeavor to calculate the surface areas soon and report back.

Thank you John! This is a major help!
Oddly enough I almost bought a trashed Traxas Spartan just so could steal the brushless and all the related mechanicals. But stopped short, because I still feel that a 90mm 8-12 blade EDF could work if i fabricated the proper air tunnels on either side of Good Donald.
The research will continue! But, first I will take this trial fit and throw it in my bossโs pool to make sure this K7 floats. ๐
Thanks again for this link!

Just for the heck of it I would like to mention that I had the great Touchwood K-7 in 1:12th scale years back and lost it in the house fire. At the time and after some research I settled on Tamiya French Blue TS-10 as my color of choice.
But upon further review last week I made a paint chip of three colors that may also fit the bill based on archival photos and some sketchy history on the actual origins of Campbellโs โBluebird Blue.โ
Then more digging came up the possibility that Sir Donald chose Fordโs auto color โFjord Blueโ that is way different than any of my choices.
So any suggestions will be helpful when the time comes.
This will be a long journey in so many ways.
Ps: Mary is driving right now, we are almost to St Louis. ๐

On one of the rc blog sites from way back in 2009. They were a small outfit in British Columbia, now out of business? ๐ค They also made fiberglass tunnel hulls it seems.
I like it DW! If you can grab go for it. Certainly a curio and a nice addition to the collection. ๐

Drifting back on this subject.
Always wanted to have a go at the Nichimo 1:200 IJN Yamato with all the upgrades and also build another Sterling Emma C. Berry. Lost my first one in that damnable house fire in 2009.
Still hoping for a 1:12th scale Speedline Shannon Class Lifeboat someday.
