    Actually, the same applies to Midway. Many attacks against the Japanese flew from there...that is why the Japanese wanted it so badly.๐Ÿ˜€
    The correct answer should be: None, they all involoved land based aircraft.

    LewZ,
    Yes it is. That said, one could Y harness the switch with the ESC for the SG. Because of different trip points, I would probably use a servo expander OR look for an electronic switch with an adjustable trip point. That way you could turn on the switch as you engage the ESC for the SG.
    The easiest option I have found is to use a computer radio and play with mix options.

    LewZ,
    In response to your question, YES. I usually hook up my SG thru an ESC which allows me to vary the smoke output. I also put the ESC thru an electronic switch so that I can turn the unit on/off, why? because I have found that with the ESCs I use that dead center(off) is hard to find. I have also put the fan on a switch. I mix the fan switch with the ESC switch, but I can run the fan alone if I so choose.

    Wolle,
    I think that you have the correct class of ship. The model in question looks quite a bit smaller and sounds like it was built as a static model.I found a n image of a very similar ship listed as a Type 143 missle boat( new construction) in Jane's Fighting Ships '71-'72.

    My approach to building requires that, except for shaft tubes, everything else in the build should be accessible and removable, if at all possible. I try to make my gun turrets removable so as to create more access to th e hull internals.
    A fully removable deck beckons a couple of issues. Water leakage in a sea being the worst case scenario. If at all possible, a deck fitting into a hull edge is a preferred method. It is more work, but makes a more stable connection and a potentially more watertight seal. With you very limited access thru the deck, I would aim to make the deck, or the vast majority of it, removable.
    Hopefully some more ideas along this line will pop up.

    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.

    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

    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.

    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.

    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.

    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.

    Do NOT apply polyester GelKote over epoxy. It will not adhere. Epoxy sticks to polyester, but not the other way around.
    If you already have epoxy on your hull, then I would just apply more coats and add colorant to the last two.

    GelKote should NOT be applied to a bare wood hull, for a couple of reasons. 1) it has not strength 20 it will not adhere very well, 30 it is soft and can be easily damaged.
    The hull should be fiber glassed or epoxy coated. In either case at least one layer of cloth should be applied as well. Many folks will apply multiple layers of glass cloth. The more applied, the stronger and more water proof the hull, but beware that the weight of glass and resin will build up quickly. After applying the FG to the hull, GelKote can be applied, brushed or sprayed. Gelkote, being quite a bit softer than FG resin, can be sanded very easily.
    If you are up to the sanding, than just FG resin and glass will work. You can always add colorant to the resin or simply paint the hull after it is cured and sanded.
    There are many ways to approach this and each individual has their own preference.
    If you are sensitive to chemicals, or your significant other will not let you stink up your residence, than epoxy may be a preferred option. While it is more expensive, it does allow you to work inside.
    Hope this helps

    The Krick system use two forms of clutch. The servo, in one direction engages the motor with the drum using two drive dogs that connect to the slip clutch at the opposite end of the drum. This causes the slip clutch to rotate the drum. At the same time, the servo depresses the micro switch to power the motor. This is all during during take up of the anchor. On the opposite end of the winch drum from the motor is the slip clutch which consists of three rubber buttons that press upon the winch drum. During take up the slip clutch, engaged with the drum, raises the anchor. If and when the anchor houses or becomes bottom stuck, the clutch slips and the gear motor and drive are protected.
    I will try to take some pictures this PM and post them. It is a nice system, expensive, but it works well.
    On my ARS, I lead the chain from the winch drum, up onto deck, over the "real" anchor winch and then down thru the hawse pipe. The system is still able to deploy and retrieve, most of the time.๐Ÿ˜‚

    Not quite sure what Lew is referring to as an auto stop on the Krick winch. What is does have is a clutch that will slip if too much drag is put upon it, such as when an anchor fetches up upon housing. This can be adjusted with a set screw.
    Otherwise it will gravity drop and retrieve.

    Yes, there is, rather, are.
    Search this site as well as modelmayhem.co.uk and you will find various homemade, some commercially available, anchor winches.
    As well, there is a commercially available unit from Krick, that I have used very successfully. I bought mine thru Cornwall Models. It is available as a single or twin drum unit. Be advised that the twin drum operates both drums at the same time.
    I hope this helps.

    Here are some pictures of the turret mechanisms. These are the #1 and #6 turrets. I have tried to keep weight as low as possible in this build. These ships, the model as well as the 1:1 versions, were quite tender and did not have a lot of stability. As such, whenever possible I lowered the servos to as low a spot as possible. These are the GoBilda servos I mentioned in my last post. They offer two types of servo clamp adapters. The brass ones shown here. These use a set screw and work well when using a solid rod. The other version, also shown, uses a clamp that works well on both rod and tubing. I would not suggest the set screw version for tubing. The adapter, both, accept .250" (1/4) rod or tube, as mentioned. I have used 3/32" tubing that I bushed up to fit the adapter in cases where long, high, runs were needed.The adapters are available with different spline counts to fit different brand servos. The aluminum stand-offs also came from GoBilda, but are available quite readily from supply houses.
    Unlike using stepper motors with a processor drive, the system I use does require some fiddling to get things aligned, but it is easy enough. Once all set, everything stays pretty much aligned.
    I will add that I have played with one of these servos as a potential radar drive. I mentioned this in my last post as well. I used a decent ESC and could easily dial in a speed of 2 rpm or less. Perfect for WW 2 radars. The maximum speed will depend upon the servo version one chooses. Speed version is obvious the fastest. The GB web site will give specs on each version of servo.
    That's all for now.๐Ÿ˜Œ
