Bronco Type XXIII in 1/35th scale

[alad61]

Oh please stop this!! I just can't take it anymore... How is a man supposed to keep on course for a Brodeen Nautilus when you keep taunting and teasing me so... It is just not fair I tell you...

Seriously though, I've been following both Manfreds and Davids threads out of curiosity with the thoughts of adding one of these to my fleet but talk about a kid in a candy shop with to many goodies to choose from He's on his favorite:biggrin:

Sam,

I'm delighted that you've found the discussion useful -- that's why I take the time to write this stuff up, for guys like you ... guy's who actually do stuff with the information put out here, you don't just skip it and move on to the next round of HALO-3 with fellow non-productive geekazoid's.

A couple of years back, as I was exploring the SAS concept -- a system perfected by Manfred Reusing decades ago -- that the key device within the sub-system would be a simple and reliable snorkel assembly. Knowing that the sub-system had to have utility in models of both long and short fairwaters, I developed two types of snorkel assemblies: the vertical, for modern boats with their long skinny sails; and the horizontal, for boats of short, squat sails. So, the two different designs of the snorkel assembly was the result.

As to your question about the snorkel assembly: No. The Type-23 fittings kit -- which I'm feverishly working to get to market -- will not have the snorkel assembly in it. The snorkel assembly will be provided with the 2.5 Type-23 SD.

And, no, there is no transverse play in the snorkel head-valve pivot.

The recommended battery is the ganging of two 1800mAh Lithium-polymer batteries together in parallel. Enough juice for at least three hours of play-time if you don't lead-foot the thing around.

David,
The fitting that you have in the photo that has a pivot for the snorkel; is that a fitting you created specifically for moving it to the diesel outlet on this model, or is that something that comes with the SD? Is there any play in it moving side to side that would cause it to hang up on the sides of the upper hull?
How long of a run time can you expect with the smaller batteries you've installed, if you include launching torpedoes?
This build thread has been very instructive; thanks for publishing your steps and the photos.

The Other guys talk about it. We do it!

Lol, Well sometimes it takes the whimpy guy sitting way back in the row to spot things people in the front seats miss.

Here's something else I noticed. Manfred and you are the only ones doing an RC conversion of the Type XXIII. Nothing on the other sites. Strange...

Nothing but cutting edge stuff here!

Am I to take it we have a new Sub-driver specific to this model?
Doe that mean the 1/96 Generic Sub-driver is no longer relevant? See here

Yes, this SD is specific to the 1/35 Type-23, Mike. It is short of length to make room for the practical weapon system. I would have preferred to keep it long so we could get the bigger 3.2Ahr battery in there, but to make room for the torpedo tubes I elected to design this to take two of the shorter 1.8Ahr batteries wired in parallel. And for the same reason, the ballast tank is optimized for the Type-23 -- it need not be as long as the 'standard' SD.

However, for those who will not install the weapon system, they can use the 'standard' 2.5 SD with no problems at all.

The 'standard' (you call it generic) 2.5" SD is the ideal product for most of the 1/96 and 1/72 single-screw model submarines out there. The 'standard' 2.5 SD is very relevant, Mike.

David, outstanding build, I really enjoy watching you take an idea and run with it.

So, deciding to make provision for a removable modified Up-Periscope camera-transmitter video system cylinder, I worked up a foundation.



Of course (as Romel pointed out earlier today ... or was it yesterday morning?) inclusion of the Up-Periscope in the sail meant relocation of the SAS snorkel assembly. This mean moving it from the sail proper and cramming it into the much lower diesel exhaust muffler fairing. And that drove me to make use of the horizontal type snorkel assembly instead of the original vertical type snorkel assembly. Done!



I tightened up the longitudinal and radial seams between upper and lower hull halves by first laying down some two-part filler and sanding that back, followed by some touch-up putty and another sand down, then primer. This is tonight's work:

No. Typical!

I would squash you like a bug, you're such a pain in the ass! However ... for a guy who has yet to get an r/c submarine in the water, you do have a very good grasp of the activity and on more than one occasion have spurred me on to do something I either overlooked, or never dreamed of. So, I let you live ... for the moment.

And your observation about the snorkel getting in the way: Absolutely right, and last night I did exactly like you suggested -- horizontal type snorkel assembly located under the desiel exhaust muffler fairing.

There! Smart guy! Take that!!!!!

that's some cool stuff, David.
way back in the late 90s, Nick Meis and I came up with a scenario where two Type XXIII's in a pool or small clear water pond would use an onboard camera and working torpedos to stalk each other, firing the torpedos when in range, and count a hit (counting coup, as it were) by some method (magnetic touch - front of torpedo to some metal sensors, or something in hull of the model...)
it looks like this rig could make that closer to reality.

Indeed, Sam. You keep score by smearing lip-stick on the tip of the torpedo after its loaded.

David

[He Who Shall Not Be Named]

That's great David.

But it seems that with either camera in place if you're going with a SAS you'll need to switch from a vertical snorkel head valve float to a horizontal type and relocate it in the diesel exhaust housing.
