I built one of these as an Aurora kit, and I remember the little hatch at the top that showed the atomic reactor. How in the name of God, could you build an RC sub this small? What a glutton for punishment, but what a brilliant design. My hats off to you, David.

Will that 1.25" SD fit in the X-craft?
recommended receiver?

Yup.

Lipton-6 or the small Wfly receiver. Any number of small 75-72mHz receivers out there.

Just watched your latest youtube video about the 1/230 Skipjack.


what's her static trim?
How far up is sail submerged when stopped?

Only a quarter inch of sail projects into the air with proper trim established.

[Albacore 569]

Impressive. filé, Its astonishing these days. Imagine agents with hidden 3d scanners in submarine yards scanning a classified sensitive part of the sub under construction. If I thought of this, a dummy like me, the agencies that like to refer to themselves as 'the company' surely must have thought of it too.

Scan is accurate even down to the hull cuts for touring her so why did Howard them make his STL files to print then with wrong blade counts on both props? Proprietary? Whatever.

That's right! Forgot to mention that in my response to Steve. Don't get lofting better than that!

Thanks for the follow-up, Andy.

Here is a 3D photometric scan of USS Albacore which is very detailed, you can use your mouse to view from all angles. Perhaps this was used for making the model?

I understood these 3d files have been created from 3d scans of the original boat?

Thanks David. Howard the 3D Print gentleman must at some point seen photos of the museum sub. So I wonder if he has research information that Albacore tested the blade count in the above parts photo too at some point?

We know from your excellent accurate historical article you did decades ago and decades ago inspired me to join this 'clazy' hobby, you mention and I still remember Albacore tested several propellor combinations in Phase IV configuration.

Perhaps that involved different blade counts as well as separation between props too? The Portsmouth NSY foundry and milling machines in the Propellor department must have been a busy place then cranking out different hydrodynamic test propulsors. I know in the UK there was a 11-blade sickle blade shaped prop tested experimentally on one of the Valiant Class SSNs, but apparently it was at the very limits of the CNC technology then at that time and it lacked the robustness of a more usual 7 blade count. A one off,



In 1/48, at 210 feet in Phase IV, would be perfect size for the water internal space and the car truck transporting at 52.5 inches. Id love if available the STL files I can resin print one for myself.

"Now back to the regularly scheduled program"

To the best of what I could find, no reference to variances in blade numbers. Just distance between the discs was altered and propulsion perimeters measured and recorded. I'm sure David Taylor went through a slew of propeller types, distances, and geometry before sending the drawings to the NSY for creation of the actual castings we are now so familiar with.

My agreement with Howard is to produce tools and parts from the masters he is sending me (more to come). From that tooling I'm to get a 'kit' as does Howard -- his to be assembled and painted. Contact him, he might be agreeable to letting me produce a kit for you. It's going to be his product, not mine. I'm only the idiot tool-maker on this job.
