1/144 Revell Germany Type 214

[Outrider]

The clear Lexan was about .080" thick. The G-10 comes in at around .30" The inverse square law rules here (the magnets), so I went with the thinner, stronger lid, Jim. Sorry.

A reliable magnetic connection seems more important than an inspection window. I can live with that trade-off.

Extra photos appreciated. Looks like the twin screw configuration is headed to a tiny Gato. One thing missing, though... Anybody want to start a petition for 1:144 guided torpedoes?

Yeah, Jim ... I got just the place for it!

Thanks a bunch to all who have recently posted, with regard to
the micro servos. Much appreciated.

The reason I asked in the first place is, since Daves 1 1/4" SD is too big for my Revell 1/144 Type 206A u-boot, I thought I'd play around with the possibility of developing a 1" wtc. Yeah, I know!! Probably can't be done, which is why I'd like to give it a go!!

I'm not only crazy, I'm also a Virgo pain-in-the-a**! Being an old timer machinist, I, at least, have to give it my best shot!!

Am currently just researching really small components to see if I may actually be able to come up with something to fit the really small sub hulls!!

Any further information regarding the servos in your posts would be great!! The tube I'm looking to use is 1" diameter with a 1/16" wall thickness! Kinda hairy, but I'm thinking it's doable!!??

Will keep intouch with all of you if I should happen upon something viable! May, or may not, become something of interest to Mr. Merriman! Jury's still out on the outcome. Once I have something workable, I will, indeed, let you all know!

Any thoughts, or sympathies, will be graciously accepted!!

Doable. Keep us informed. And spout up when you get into a jam.

Gary,
It can be done. I am building a 1/96 Aluminaut that has a 1" tube. You are a machinist and that will help.

It won't be easy.
Peace,

As the 206 is largely cylindrical, you may want to consider making it a dry hull with a free flooding bow and stern. This will increase buoyancy (and this class needs all the help it can get stability wise) and will maximise room inside for the equipment. You could machine a bayonet ring from aluminium, this is much stiffer than plastic enabling you to make the ring very thin, and incorporate a small o-ring. It will also help stiffen up the plastic hull.

Good tip, Subculture!! Thanks alot!

I was considering making it a wet hull, but like your suggestion much better!

The interesting part will be where exactly to cut the hull, once assembled, so as not to
weaken anything structural!!

I found some really small sub-micro, and lightweight, linear srvos on the Hobby King website, and ordered 2 r.h. and 2 l.h., along with their smallest ESC! These will be, by no means, the definitive components, but will, at least, give me an idea as to fitting things within a 7/8" i.d. plastic tube!!

Am hoping to achieve a relatively high degree of success with this little R&D project. "Film at eleven!!" Hah!!

Would anyone be willing to pass along brand/model information with regard to the "microbe-sized-servos" that David referred to??

If not, I will completely understand!

Please rest assured that this little venture of mine is definitely not intended to "upstage" Davids SDs, but merely to find a smaller alternative for the "really small" sub community! I would be most pleased to pass along my findings to David, and SubDriver, et all, for the betterment of our little sub community!

Thanks again to all of you for your assistance as I embark on what may well become a "major brainf*rt"!!

Check out this 1/350 Ohio I found on a German RC site

You can make a radial split at the point I've highlighted in red. If you want to make the forward planes operational, then you could make a second split just behind the planes.



If you turn some aluminium bulkheads, you will strengthen the hull not weaken it. Modellers have been making these miniature subs for decades, but back then it required more specialist skills to make them work well- the radio tended to be bulkier, and the batteries gave very modest running times. Now you can make a miniature model perform as well as the bigger boats.

The biggest hurdle to overcome with a 206 is going to be your vertical CG. These boats are known for being tender in model form- that larger sail area makes them rock and roll, so i would make every effort to keep the weight low down. The 214 is a much easier beast to tame, a modeller in the UK has converted one, and it works extremely well.

No problem at all. My work is part of the whole; you're not up-staging anyone here -- you're contributing to the group-knowledge.

Here's the microbe-sized linear servo Caswell sells: HEY! It's not in the catalog!!!! MIKE!!!!!!!....... help!

No. I got it wrong, it's listed: http://www.sub-driver.com/linear-servo.html

Morning, all!!

Redboat-

Many thanks for the inspiration which is definitely a confidence builder. If only I could speak and understand German, however, the photos speak volumes of words!! Pretty universal "language" for model builders!!

Subculture-

I very much appreciate your valued input and drawing!! This will certainly give me some excellent guidelines upon which to make this venture successful! Any suggestions for weight material?? Bbs, buckshot,etc??

David-

Thanks so much for your "blessing"! Also, thanks for the link to those neat little servos! They may well be quite a bit smaller than the ones I mentioned ordering from Hobby King. Nice and compact is certainly a big plus here!! An actual case of where "less" is truly "more"!!

The support and assistance I'm receiving from all of you is immeasureable, and extremely appreciated!!

Now as soon as the caffeine kicks in, I'm off to cut up some acrylic tubing and see what I can see!! Am using acrylic now as I happen to have it on hand, but will go with polycarbonate when I'm ready to build the "real-deal"!

Thanks, again, gentlemen!!

Have a great weekend!

Didn't realize that was out there!!
Thanks, Subculture!!

Hi, Subculture!

Am thinking there will be a potential problem with the rudder movement of this little sub! There appears to be very little room within the upper and lower rudder pivot arms in which to provide for steering linkage!! Any ideas? Since she's a 1/144 scale, she'll certainly cause a few more brain cells to explode!! Hah!!

Was considering the possibility of "fabbing up" some sort of horizontal "gizmo" through the leading edge of the rudder and running the steering "rods" through the back end of the sub to connect with my steering servo in some oddball fashion!
Don't think a linear servo will be the ticket in this case, but....?

Would be extremely visable, but, I'm thinking that the end would justify the means.

Anyone have thoughts on this? Any suggestions would be most appreciated!

I think you've chosen a diffcult subject to convert. The 214 will be a lot easier. the 206 is feasible, but you're getting into watchmaking territory if you want internal linkages.

personally I think midget submarines are the best subjects for miniature subs. The scale still remains fairly coarse even at very small sizes, so arranging linkages, and ensuring effective control surfaces and prop size are all within reach.

[crazygary]

I, actually, have a 214 on the way to me that would have been my first choice for the 1" diameter cylinder, but while waiting for it to arrive, I thought I'd delve into the possibility of doing the 206! It will, more than likely, end up as an unexpected gift to my grandson to build, what with the clear uncertainty of being able to effectively steer her!

I also have a Lindberg 1/240 Gato, that interests me! Not really sure if a 1" tube will fit comfortably within the confines of the "oddly" shaped hull interior, but will likely look into it! Got this thing about burning out brain cells!! Hah!!

Meanwhile, my 1/144 Trumpeter Kilo continues to glare at me when I walk into my hobby room!! I'm very much looking forward to that build, as there are numerous threads on this, as well as other, sub websites!

Kind of regimented myself to finish my latest "target", though, before jumping into the deep end!! A feat which I am
very much anticipating!! My tug is probably 85% completed, and will "git er' done" asap!!
