I reverse engineered the sail in a solid modeler, split it...
Here's a video of the completed design prototype:

I ran across this hack and have been testing it out. If you take some aluminum foil and cover the end of the tube before you put the cap on, it will prevent the silicone from curing. I have just opened up a tube that I last used a couple of months ago and the silicone is perfectly fresh.

Start with a small square of aluminum foil



Push the edges down and then put on the cap.

This is a concept sub designed to replace the Walrus Class submarine (sniff, sniff) and I do love the Swedish designs. The fact that it showed up in Bob's catalogue of 3D subs was thrilling to me.
I upsized it to 1/66th scale or ~867mm or ~34" in length.

I made a modification to the bow. Split the bow so I could throw a screw up from underneath, but I have made another change to the aft end that (I will post later) I may not need to fasten the front down.

Using my 3D Walrus Propellor (I never used it because I had a brass prop made) and modified it for this sub. It has chunky blades and I do not mind. I am not sure of the performance as this was one of my first props I made in Fusion 360.

Good news for anyone interested: the French Navy ship plans database is back online!
However, I find the site isn't at all intuitive when it comes to downloading the plans. Too bad.

Its a 1/32 scale 32nd parallel type XXI uboat, I THINK i am the third owner, Its original internals have been removed, and a custom built OTW dive module put in it. Hopefully next year it will have working lights, periscopes/snorkel, and torpedoes, as well as a new more accurate paint job.

FWIW I am setting up a retractable mast system on my 1/72 ALFA sub.

At least an IP67 would do the job and I also need it to be small size if possible.
Amazon lists several quoted to be IP68 but I really have my suspicions about these being able to meet even IP67.
Hitec has a selection of IP67 models and I am inclined to try one of these, particularly since they are a reputable make.

My question is whether there are other manufacturer's servos out there that people have used with success.

Thanks

What is a good radio for controlling an RC sub nowadays?

I've got a Radiomaster TX16S for my other models (one TX + many RX and different model configs)

Is that a suitable model for subs as well, or should I get a dedicated Sub Radio? I'm thinking I should get a dedicated sub one...and I understand that lower freqs are better for signal propagation?

How many channels do I *need*?

Throttle, Rudder, dive planes, ballast fill/empty, Torpedo launch? (maybe?)

I found this one that's a Dual Band 2.4 GHz and 900 MHz:
