    AlessandroSPQR,
    Thank you for your kind words. Please ignore my rumbles, I just turned 70 and with not much else to do, I build models. My body is not always in agreement with my intentions...nothing new.๐Ÿ˜ I do wish I was 20 years younger...sometimes, but then reality strikes and reminds me that I am better off where I am.
    So...back to the build๐Ÿ˜‚

    Toradog I realized that this is often hard work even though it is a hobby and we enjoy doing it.
    In some cases I was so stuck in uncomfortable positions just intent on making something of the ship models that in the end my back was in pieces.
    Sometimes after hours of assembling very small pieces my eyes hurt.
    But what a satisfaction in the end.

    My eyes are blurry, my hand(s) are shaking, my knees and back are killing me from standing. That said, the first coat of superstructure paint is in place. Lot's to fix, touch up and make better, but it gives me a starting point.
    Next up will be to remove the superstructure and paint the main deck. The superstructure decks will be last, after the touch up coats.
    Unfortunately the sun is washing out the colors somewhat. But the idea is there.

    Toradog I'm sorry you're making a lot of effort for this titanic job but it's worth it.
    This naval model is majestic.

    Chum,
    I am soo worried that I might have to have another Screech and tonic!๐Ÿคฃ
    I am not too concerned. Every design was unique and if there are no pictures, well then, who is going to prove me wrong. The only rivet counter I am concerned with is the one I see in the mirror(when my eyes open)๐Ÿ˜€

    I have decided to take the plunge and begin the camouflage on the superstructure. I am a bit more than 4 hours into it and you can see that it will be a bit more. My eyes go crossed after an hour and my back and knees begin to sag. A labor of love, or just plain stubborn. (yes Dear)
    While I really like MS 12 Modified as a scheme, the only documentation available is a few photographs. Most unfortunately they are all of the starboard side. Therefore, my portside will be entirely made up...๐Ÿ˜ญ One can also see why details, deck and bulkhead, have not been added, yet.
    That is all for now until my body recovers.๐Ÿ˜Š

    Wouldnโ€™t over worry about the port side. Just use whatever info you have or your considerable knowledge. There might be a few purists who notice deviation but just think of it as only counting every other rivet! ๐Ÿ‘

    Doug,
    The wing turrets only rotate outboard. I spared the Capt and crew from self destruction. The rotate about 115 degrees, I have not measured it exactly. if turrets 4-6 rotate across the stern, and the wing turrets are linked to follow them, then the one wing will stop at 180 degrees while other opposing turret rotates outboard. Does that make sense? I'll shoot another video to illustrate it.
    Meanwhile, suffice it to say that the wing turrets can not rotate inboard of 18o degrees relative to the keel.

    Thank you Allesandro. You are being too kind.
    Here is a link to a video of the turrets and gun directors functioning under local as well as director control. Sorry by the aft superstructure is off at the moment.

    Nice one TD๐Ÿ˜€๐Ÿ‘
    BUT! I'm not so sure that Cap'n and crew would appreciate the outboard turrets (7 & 8?) rotating inboard and shooting their own superstructure off๐Ÿ˜ฎ๐Ÿ˜ 
    Are they somehow mounted A about F (๐Ÿ˜)? I.e. out of sync with turrets 9 & 10.
    Or do they just need limiting to ca 170ยฐ outboard traverse?
    Cheers, Doug๐Ÿ˜Ž

    B,
    Yes the mixing is done in the transmitter. It is very similar to the mixing done in OTX, but is simpler as an entire step is combined with another.
    The mix is activated with one of the panel switches. Your Taranis should operate pretty much the same way.

    Hi Toradog, I'm slowly starting to read many messages that I hadn't seen for about two weeks or so.
    I must say that your work and your explanations are real lessons. He is a fantastic and admirable role model.
    Thanks for sharing.

    Remote directors also increase the rate of fire of the gun mount. The sighter and trainer, who use to be on the mount, can now keep their sites on target while the gun fires. In the "old" method, the concussion of the gun's blast thru the sites off so that the target had to be re-acquired. This was now no longer the case. As such the gun crew only had to load the gun. This is why good experienced crews on the 5"/38 could fire up to 10 rounds per minute, 20 round per minute for a twin mount.
    Juneau had 8 such mounts x 20rpm= 160 per minute.Not a CIWS, but I expect it was impressive.

    Chumm,
    Without getting too deep into the history of the world, remote gun directors were developed and adopted to remove to a remote location, one that is somewhat isolated from the vibration caused by the gun firing, the director. Guns still retained the ability to be trained and elevated by their crews, referred to as local control. Another added advantage is that the director could be located much higher up on the ship while the guns remained on the main deck, or there abouts. This, of course, greatly increase the visually sighting distance of the director. Remember that this was all done visually, until WW2 when radar stepped in. But early radars were susceptible to vibration so mounting them on or near guns was not an ideal solution. Heavy cruisers and battleships regularly knocked out their own radar systems while firing their main guns. Usually it was tube failure which could be quickly replaced. As well, radar has a horizon as does the MK1 eyeball. Again, higher is better. USN designs mounted the radar antenna on the gun director while remote mounting it's electronics and controls to a remote location.
    So... my directors can "search" for a target and upon acquiring one, command it's linked gun turrets to follow it's movements.

    Do you use a mix in the tx to simulate the target โ€œacquisitionโ€ & tracking as the targetโ€™s bearing changes? Those mix lines must be quite interesting.๐Ÿค”

    Chumm,
    There is a story about that. I had planned to be able to elevate, rotate and fire( LED flash) the guns. This was all based upon the barrel design that the 3D printer used on his previous 5"/38 single barrel turrets.
    When his twin turrets arrived, I found that there was not the room to do what I wanted. I could have sealed a miniature servo into the turret, but I did not like that idea, things break. That killed the elevation idea. I would have to do a whole post on just the turret build.
    I trashed the LED idea when I had brass barrels turned for the turrets. I had asked for thru bored, but did not get it. I may try to bore them yet.
    So the short answer to your question is that they rotate only, but they do so selectively. The forward three operate as a unit, but can also be mixed to respond as the gun director does.
    The aft center group is unit, similar to the forward group, and it too will link to the director. The aft wing turrets are independent, can be linked to the center aft group and also the center group and the gun director.
    All of the linking/mixing is done in the transmitter.

    As sung by The Rolling Stones, โ€œ You canโ€™t always get what you wantโ€ฆโ€ฆbut if you try sometimes, you get what you needโ€! ๐Ÿ˜‚
    In real life I understand the purpose of the gun director. But Iโ€™m completely ignorant regarding how one operates on a model & how it interacts with the turrets. I await enlightenment.
