HMS X-Class Stickleback Midget Submarine

[Subculture]

The x-craft were essentially a smaller Holland class sub, with a simplified hull form to speed up construction, and some bow revisions for (slightly) better seakeeping on the surface. Like the Holland's, the skippers tended to trim them with a flooded or partly flooded rear tank when surfaced to get the stern low in the water, which is why photos of the boats in action tend to show them in a slanted trim when surfaced. Some modellers emulate this by incorporating a shiftable ballast trim e.g. move the main battery or suitable weight with a servo.

Romel,

Well after watching the great video you put up, what to my surprise was a YouTube video that came next.

1:12 Scale British X Craft RC Submarine (youtube.com)

It was a video that Bob Martin put up about 5 plus years ago of the X-Class submarine that he had. His video will be extremely helpful as I start the build up of my Stickleback.

So! Thank you again for providing me with all this great information. And thanks to Bob for doing the video on his X-Class.

Thanks Romel!

That video gives me an idea where I need to be as far as how it is set up for water operation underway.

I have been going through some of the accumulated parts from previous builds.



These are just a few of what I have that I could use on the Stickleback. At this point I am not sure if I will incorporate a simple low pressure ballast system for this boat, or go with just a partial submersible surface runner!? It's just going to be a fun boat for the pool! I have a lot of David M. photos and ideas as to how to install all this into a 2" cylinder.

Time will tell...

Making more progress on the Stickleback.






The photos show additional lower hull sections, and also the 2" cylinder that I will be using for the WTC.

I have started to print the main hull for the Stickleback!





The above two photos show the first two bottom bow sections.

Hi Bruce,

I got the files from CGTraders. STL files at 1:24 scale at 100% size. I increased the size to 110% and that is the max that I can go with my Dremel. With that in mind I will be going with a 2" cylinder. That means I will have to pull off a David M. cylinder build. Going to be interesting! But, I will make it work!

Rob

Yes you will!

[rwtdiver]

So around 673MM in length, what size cylinder are you employing? Where did you purchase the files?

Thank you for the files. I have used these type extenders on some of my boats. The majority of my boats are over 36" long, and in my pool even with the extender, all I can say is I am glad I have reverse. I see you use Autodesk Tinkercad. It's very simple to use and you do get great results.

Thanks Bruce.

Here are a few more photos of the HMS Stickleback.





My plane with this boat is to take it all the way to full diving capability (WTC/SD) and also do some weather on the final finish. The other good thing about this boat if I getit operational is, it will be a great boat for the pool. Every other boat I have built except for the 1:77 scale Nautilus were just to big for the pool.

Rob, nice addition. I also drive my subs in my pool, I I often print the rudders larger or add a rudder extender to increase the turning ability. Happy to share my STL files so you can see what I design.

Romel,

How did you know that I really like to have a bowl of popcorn on my work bench while I am building. Great site with some good recipes.
