Absolutely correct Sir Dave! There are statistics, lies and damned lies! Test gear calibration was a professional pain in the ... for me for many years. All comments re ambient temperature, internal resistance absolutely spot on👍 Goes back to my comment in the debate you mentioned, pay a bit more for the batteries and you'll get more out of 'em. But unfortunately 'what goes in does not (always) come out' 🤔 The capacities printed on the jacket should always be taken with the proverbial pinch! They are only an indication of perfect performance in 'this the most perfect of all possible worlds'! I remember matched cells too, much more expensive, and not critical for scale ships. Cheers Doug 😎
Hi Norm, Norm (!) Oughs drawing may well be 'as built'. During the war she received many mods. Depends on the time snapshot you want to recreate. I may be wrong about the island (photo perspective) but it seemed that way. I remember standing on the topmost island deck of a Colossus class carrier, at the foot of the antenna mast, looking down at ants crawling about on the deck, and the even smaller ones on the dockside! 😉 I was up there inspecting the COMMS antenna fit. That was my job the last 30 odd years. On existing ships I would survey the COMMS systems for upgrades and refits. For new build ships I would discuss the requirements and possibilities with the navies and then discuss with the shipyards how to achieve them! All good stuff, but the last 10 years I was getting a bit stiff for the climbing, so I sent a younger colleague up while I discussed the existing system and any problems with the crew in the Wardroom😉 Can't see your pic, the site only accepts jpgs etc🤔 An irritation that has often cost me time to do conversions 😡 We'll have to 'gang up' on Fireboat (Stephen) to get this improved. i often wanted to upload a pdf page, but had to convert to jpg etc first😭 Where is this mysterious platform? Maybe I can find it. A large searchlight would not surprise me. Could also be an early radar antenna, need to research the types mentioned above. If the launch has a cabin it may be an 'Admirals Barge', and Admirals had a lot of freedom to paint them how they wanted. So black and mahogany sounds very appropriate to me 👍 Often said on this site (and elsewhere) but: 'The only silly question is the one you don't ask'! Keep up the good work, Doug 😎
Hi, I made the bridge to my drawing. I think it's right. I would think that Noram Ough had his basic dimensions correct. If not I might as well start over! In the pic I am attaching, there is a platform with what looks like a very large searchlight, but it is not clear enough to be sure, Seems a bit unlikely. I am giving her a 36 foot launch. I assume it would have been grey, though I am tempted to paint it black, with varnished wood cabin and mahogany foredeck. I am beginning to feel a bit stupid asking so many questions. I hope you don't feel 'oh no not him again!😡 Never had anyone to consult before. Most of the time here it's me helping others in our little club. You got around a lot of ships all over the world I think. What were you doing, or shouldn't I ask? Regards Norm
Hi Dave, Yep, agree, to a certain extent. I have also had surprising results with 385 / 400 sizes; for instance with my 110cm heavy and cramped submarine. On the surface it outruns most boy racers 😁 Not exactly scale but all good fun. A little down angle on the forward planes and it throws up a beautiful handlebar moustache of water 😊 Not too much angle at speed or it sticks it's tail in the air 😲 No, the main question was that Fred already has the 700s so I simply suggested a decent match, 5mm shaft and so on. If he wants to spend on more motors fine. the the 3mm shaft would surely save weight, mostly through the smaller tube. Don't know the rest of the detail of the boat; beam, draft, safe waterline etc, but I would have thought a 3 footer would have a reasonable carrying capacity, like my 3 and 4 foot warships. Most of those run on multiple Speed 600s. And there I have the usual warship high length to beam ratio and associated stability problems! Like I said; he pays his money and takes his choice. Personally I would give it a whirl with the 700s since they are in the box! Maybe though with a 3 or 4mm shaft and appropriate coupling so he can adapt later if he wants to. Would still think a pair of 35 props would do the trick. Whatever, have fun Fred. Look forward to the Sea trials Report! (Wrote, read and commented enough of 'em in my old job!) Cheers Doug 😎 Oh no! Yet another thunderstorm just started, my terrace is already swamped 🤔
Some info. on radar, armament and wartime mods! 'Ya pays ya money and yer takes yer choice'! 😎 "Armament, electronics and protection The main armament of the Illustrious class consisted of sixteen quick-firing (QF) 4.5-inch (110 mm) dual-purpose guns in eight twin-gun turrets, four in sponsons on each side of the hull. The roofs of the gun turrets protruded above the level of the flight deck to allow them to fire across the deck at high elevations. The gun had a maximum range of 20,760 yards (18,980 m). Her light anti-aircraft defences included six octuple mounts for QF 2-pounder ("pom-pom") anti-aircraft (AA) guns, two each fore and aft of the island and two in sponsons on the port side of the hull. The 2-pounder gun had a maximum range of 6,800 yards (6,200 m). The completion of Illustrious was delayed two months to fit her with a Type 79Z early-warning radar; she was the first aircraft carrier in the world to be fitted with radar before completion. This version of the radar had separate transmitting and receiving antennas which required a new mainmast to be added to the aft end of the island to mount the transmitter. The Illustrious-class ships had a flight deck protected by 3 inches (76 mm) of armour and the internal sides and ends of the hangars were 4.5 inches (114 mm) thick. The hangar deck itself was 2.5 inches (64 mm) thick and extended the full width of the ship to meet the top of the 4.5-inch waterline armour belt. The belt was closed by 2.5-inch transverse bulkheads fore and aft. The underwater defence system was a layered system of liquid- and air-filled compartments backed by a 1.5-inch (38 mm) splinter bulkhead. Wartime modifications While under repair in 1941, Illustrious's rear "round-down" was flattened to increase the usable length of the flight deck to 670 feet (204.2 m). This increased her aircraft complement to 41 aircraft by use of a permanent deck park. Her light AA armament was also augmented by the addition of 10 Oerlikon 20 mm autocannon in single mounts with a maximum range of 4,800 yards (4,400 m). In addition the two steel fire curtains in the hangar were replaced by asbestos ones. After her return to the UK later that year, her Type 79Z radar was replaced by a Type 281 system and a Type 285 gunnery radar was mounted on one of the main fire-control directors. The additional crewmen, maintenance personnel and facilities needed to support these aircraft, weapons and sensors increased her complement to 1,326. During her 1943 refits, the flight deck was modified to extend its usable length to 740 feet (225.6 m), and "outriggers" were probably added at this time. These were 'U'-shaped beams that extended from the side of the flight deck into which aircraft tailwheels were placed. The aircraft were pushed back until the main wheels were near the edge of the flight deck to allow more aircraft to be stored on the deck. Twin Oerlikon mounts replaced most of the single mounts. Other twin mounts were added so that by May she had a total of eighteen twin and two single mounts. The Type 281 radar was replaced by an upgraded Type 281M, and a single-antenna Type 79M was added. Type 282 gunnery radars were added for each of the "pom-pom" directors, and the rest of the main directors were fitted with Type 285 radars. A Type 272 target-indicator radar was mounted above her bridge. These changes increased her aircraft capacity to 57 and caused her crew to grow to 1,831. A year later, in preparation for her service against the Japanese in the Pacific, one starboard octuple "pom-pom" mount, directly abaft the island, was replaced by two 40 mm Bofors AA guns; which had a maximum range of 10,750 yards (9,830 m). Two more twin Oerlikon mounts were added, and her boilers were retubed. At this time her complement was 1,997 officers and enlisted men. By 1945, accumulated wear-and-tear as well as undiagnosed shock damage to Illustrious's machinery caused severe vibrations in her centre propeller shaft at high speeds. In an effort to cure the problem, the propeller was removed, and the shaft was locked in place in February; these radical measures succeeded in reducing, but not eliminating, the vibrations and reduced the ship's speed to about 24 knots (44 km/h; 28 mph).["
Hi Norm, the GA I have, as on active service 1940, doesn't show any sponsons between the 2nd 4.5"AA and the director abaft the front of the island!? It also shows TWO 8 barrel pompoms starboard between the radio mast and the island! It also shows the 4.5 turrets much flatter, almost flush with the flight deck! What you have may have been later add ons. I suspect that the smaller square one was simply for access to the radio mast and the tuning unit which would be at the foot of it. Since the round one also has a door and bulwarks to stop people sliding overboard it would have been manned sometimes and I suspect that either a Quad Vickers 0.5" MG AA (see pics) or a 20mm Oerlikon AA might have been mounted there. Most carriers initially had up to 8 of these Vickers, but they were b.. useless against fast metal aircraft and were soon replaced with 20mm. So if I were you I would be tempted to put a twin 20mm on there. At some stage of the war it would be correct! The Vickers is impossible to find in a reasonable scale, only teeny weeny etch sets. I once went bonkers putting one together in 1/600 scale for my HMS Manxman, makes yer eyes go funny 😲 There are 8 at 1/350 on my Ark Royal 😡 I'm currently in contact with Adrian Smith of Battlecrafts to get some made up in 1/72. He's just done me some 4.7" guns for my 1/72 HMS Hotspur H class destroyer. Not cheap, but damn good 👍 If he ain't got it he'll make it if we can give him photos and drawing or reference sources. The original ship builder often has such an online archive; Vickers for instance. http://www.battlecrafts.co.uk/ What date are you depicting with your model? Can you post a pic of your plan? Where did it come from? I've also forgotten what Scale you are building! Aha just found it 1/192 ! Hope this helps more than confuses! Cheers Doug😎 Last pic, Illustrious, date unknown, is bit tiny but does show 'something' on sponsons aft of the 4.5s. look like twin 40mm to me, so maybe the sponsons were enlarged at this stage?
Hi Dave, you won't find a Conrad anything anywhere else but on the Conrad (or Amazon/Ebay) sites! But if you look for the Turnigy HT-6 you will find it on HobbyKing, it's the same damn thing for nearly half the Conrad price. See pics. Pure badge 'engineering'! Also just bought some Absima LiPos 2s 4000mAh from Conrad, €40 each. Today I found out that Absima is in Nürnberg (Nuremberg) just up the road from here, same batt €25 😡😭 Conrad will shortly be getting an appropriate mail from me! NO more Reely stuff for me!! I found the HT-6 very easy to set up, amazing what they pack into a $45 set these days. My Spektrum cost 12 times that a few years ago and doesn't do an awful lot more and is more complex to set up 🤔 Won't mess with mixer boards or two stick motor control just yet. Can use the mixer functions in the TX 😊 Have tested the HT-6 with various ESCs; e.g. Graupner Navy VR30 and Mtroniks Viper Micro10, no problems. When the new 2s LiPos are charged the next test will be with a Turnigy brushless ESCs and the BL I want to put in the Sea Scout. Progress is slow but sure. Why do I get on faster with electronics than with shipbuilding!!?? 😉 You're right; Mode 1 or 2 (3 and 4 are also available!) don't matter much. With this set you can assign any control element stick, switch, or pot to any channel (i.e. RX output) you want, and very simply - not like the Spektrum🤔. Like it.👍 I also like having the two pots available for proportional control; gun turrets, cranes, monitors .... 👍 And still switches left over for lights, sound .... Very versatile 👍👍 Only irritation is it won't go into operational mode until all switches are forward and the throttle (left stick) is pulled right back - motor off for an aircraft - safety feature. Minor irritation for a boater but pull the stick back and all is OK and you can then operate normally. Used the spring removal method on my old Graupner 40Meg MC-10. That box was a pain to set up as well🤔 I could programme the radio ATE for the old Home Office Type Approval lab faster, but then - I wrote the software 😉 Cheers Doug 😎
Brrrrrrrrilliant! 👍👍👍 Best 'tin bashing' I've ever seen. Would love to see video of them in action 😉 Type 21!? Navy or industry? I've seen the insides of many ships, from Colossus class carrier to Type 45, but never the 21. Keep up the good work. Cheers Doug 😎
Hi Krampus 😉 Even an Admiral asks permission to board the Captain's ship! Even if the 'Captain' is only a lieutenant jg! Won't be much sailing though when you come back in December 😲 Maybe my hovercraft on the ice !? 😲 Cheers Doug 😎
