  1. the tamiya is not a click fit either. Particularly the engine compartment with those xxxxing magnets the panel do not fit right easily I ended up gluing mine on. Same with the spit lX
  2. I typically use model master interior green and Tamiya yellow green ( one of the rare exceptions to not using acyralics) ymmv but I find both vg
  3. I know otoh I rarely pick my displayed planes and look in there. On the d 5 being historically accurate and ease of painting coincide. An important thing to me right now as I am finally finishing my F 16 which I had sitting on the shelf for the last 4 years or so.
  4. here is a picture of a d 20 under construction showing the painted wheel wells. I agree that the D 5 probably had nmf or silver painted wheels wells
  5. like many ww2 things there is a who knows I copied and pasted the discussion I sited above. Dana bell is well known in the modeling community. I think the p-51 d 5 na was early and thus the well bays were probably nmf with the spar being yellow zinc chromate but who really knows so not a criticism just part of the fun of discussion Dana Bell Mustang corrosion control... Fri Oct 1, 2004 08:33 160.111.69.104 You've got several options here, but unpainted "natural" aluminum with a yellow zinc chromate main spar is the most common for P-51Bs and Cs. The early Allison-engined Mustangs used the standard prewar corrosion control finishes for the wheel wells and struts: two coats of primer and one coat of aluminized lacquer. In 1942, before the Merlin-engined Mustangs entered production, North American was granted permission to build Mustangs without interior primers as a means of speeding production. The main wing spars were generally primed with a single coat of yellow zinc chromate to protect the alloy spar itself, to avoid dissimilar metal corrosion in the areas where the spar contacted the inner faces of the aluminum skin, and to reduce static electricity buildup on the aft face of the spar (where the main tanks were located). There is a chance that some early Bs and Cs were delivered with unpainted spars, but I've never found more than a slight possibility of that having occurred. As part of the cost- and time-savings measures, all other non-cockpit interior areas were left in unpainted aluminum finish. Since there were several grades of aluminum present, this led to corrosion issues on the Mustang, and at some point (I've not been able to pin down a date or place in production) wheel wells began to appear in overall yellow zinc chromate. I know for sure that this happened late in P-51D production. The problems had certainly been identified during B and C production, and fixes were ordered, I just can't find proof that these earlier models actually got the fix. If, for any reason, a second coat of primer was applied to the wheel well, it would have been green zinc chromate (by that time, the same as Interior Green). I haven't seen evidence of that during WWII, but it could have happened. As for aluminum lacquer with a yellow spar, that's the one option that didn't happen and actually makes the least sense. The object was to save money and time, so most corrosion control finishes were eliminated. If aluminized lacquer WAS used, it would have been used to overspray the entire well. (Leaving the main spar in yellow in a lacquered well was made more difficult by wartime shortages of both Magic Mask and Parafilm.) This may be splitting hairs on an OOOOO paint brush, but an aluminized lacquer finish just doesn't look the same as an unpainted aluminum finish, even in scale. Hope something here helps and makes sense... Cheers, Dana Dana Bell AM Mustang wells... Fri Oct 1, 2004 09:11 160.111.69.104 I plan to use an aluminum lacquer effect in my Accurate Miniatures P-51A wells - it's certainly the best documented option. The caution here is that later Allison-engined Mustangs MAY have had unpainted wells with a yellow zinc chromate spar - that documentation probably won't turn up until both of us have completed our models! Cheers, Dana Dana Bell Not so, sir... Fri Oct 1, 2004 07:50 160.111.69.104 I'm afraid "current thinking" is wrong on this one - there is no evidence of aluminum lacquered wheel wells with a yellow main spar, while there are plenty of photos of overall yellow P-51 wells. You've got to ask yourself how the manufacturer would have been able to paint the well aluminum without getting any overspray on the spar, or why anyone should even attempt such a thing. Dana Dana Bell Mustang subassys... Fri Oct 1, 2004 15:22 160.111.69.104 A good thought, but not backed by photos of the production line. The wheel wells were not actually subassemblies - they were just spaces for the wheels. The top of the well was the inside of the skin, as was the bottom. The back was the spar - everything else was gear-related or a rib. The spar was painted with yellow zinc chromate prior to construction of the wing. Any other finish was applied during construction. Cheers, Dana Dana Bell Mustang wells... Fri Oct 1, 2004 09:03 160.111.69.104 Sorry to leave that post without details - I've added an explanation above. You're right that the effect was the result of the production process. I was distinguishing between unpainted aluminum and aluminum lacquer - two different processes in manufacturing and two different effects in modeling. Many modelers probably don't care - after all, we all have to paint the plastic "silver" - but with the wide variety of aluminum finish paints now available there'll be a lot of folks looking for the most accurate effect in their painting. I seem to remember modeling as an easier hobby back in the days when everything got brushed with a coat of Pactra Flat Aluminum - the paint had a grain larger than a silver dollar, but I loved that stuff! Cheers, Dana Dana Bell Anticorrosive colors and P-51s... Tue Aug 27 10:19:29 2002 209.244.225.103 There are really three phases of wartime painting of Mustang wheel wells - all related to corrosion control. At first, the metal surfaces were to be painted with one coat of zinc chromate (yellow), one coat of tinted zinc chromate (green), and one coat of aluminized lacquer. This finish appears to have been limited to Allison-engined Mustangs. Two things happened in 1942. First, a shortage of aluminum ended the use of the aluminized lacquer and forced the reformulation of green zinc chromate. (This led to the use of other colors for wheel wells and struts - for example the Neutral Gray on Lightings and Bronze Green on some P-39s and B-29s.) Second, the AAF allowed North American to produce AT-6s, B-25s, and P-51s without primers to ease production. (Boeing got similar permission for its B-17s.) This is what led to the unpainted wheel well noted below. Throughout this period, the wing spar appears to have consistently carried zinc chromate (yellow) primer. (The primer reduced corrosion where the spar contacted the aluminum sheet and reduced the buildup of static electricity - an important issue with the fuel tanks mounted just aft of the spar.) This combination, as noted below, was common on Bs and Cs, and most Ds and Ks. By 1944, the AAF was receiving complaints about corrosion in a number of aircraft, including the Mustang. Some unspecified action was required, particularly to reduce dissimilar metal corrosion between structural members and skin panels. Some manufacturers gave the structure a coat of yellow zinc chromate before adding the skin. Some left the structure unprimed and gave the inner surface of the skin a coat of yellow zinc chromate. It's not clear how North American handled the problem, but there is one undated color shot of a P-51D (or K) production line showing the entire wheel well primed in yellow. This is just a general explanation - it won't help you know what color the wheel wells would be on any particular aircraft. But you can make your own informed decisions based on the date you suspect any particular aircraft (and not just a Mustang) was manufactured. Cheers, -Dana Dana Bell Green Zinc Chromate... Tue Aug 27 10:30:45 2002 209.244.225.103 Interior Green is the ANA color name for the zinc chromate green mixed from black and zinc chromate yellow. Up until 1942, the zinc chromate green formula also included aluminum paste or powder - this was dropped due to the wartime aluminum shortage. For about a year, each company did some experimentation trying to match zinc chromate green using different tints (though the Navy also used a red tint). In 1943 the ANA colors came along, and after that, Interior Green quickly became standard. -Dana
  6. Specifically what the hell was the color. from the post from dana bell and what i can recall from my tamiya build the spar was yellow zinc chromate and the wheel bay was nmf no anti corrosion was added this willl save a bunch of masking time http://forum.largescaleplanes.com/index.php?showtopic=41871
  7. here is a place to start https://en.wikipedia.org/wiki/Fairchild_Republic_A-10_Thunderbolt_II http://www.largescaleplanes.com/Marketplace/Tweaks/A-10.htm
  8. hey I found something else to consider for polishing powders https://www.uschivdr.com/shopping-categories/shop-colors-paints-pigments-primer/metallic-colors-pigments/ https://www.uschivdr.com/products-in-detail/polishing-powders-metallic-pigments/
  9. forgive my ignorence which metal color paint are you referring to? Mr metal color or one of the acrylics? I generally use alclad which is nice stuff but nasty stuff aha after a search you mean the vallejo line don't you. The search also revealed SNJ is OOB so sad I have a bit of their polishing powder left that is great stuff for NMF
  10. I was also wondering if the shrouded exhausts from the tamiya kit will fit. They are already drilled and I have left overs from my tamiya
  11. I was talking to a F 18 pilot once at an airshow. I asked him about his scariest time in the jet. he told me they had to launch in a gail to shoe off Russian bomber testing the fleet response. Getting it back on board was hard due to the lack of visibility and the fact the carrier was heaving so much it's propellers were out of the water as it dove into the waves.
  12. Thanks for the reply. I have used the RB sets and although they look great they are insanely hard to put together. I have fine motor control I am a retired general surgeon so no fimble fingers. I think I will the fine molds a try
  13. I had never seen the fine mold seat belts how many do you get in the box a bit pricey for one or two belts though
  14. I have the flying girl from pynups ( cutting edge) no insignia or placards. I did sweet Arlene would be willing to trade something for it if anybody wants. http://davidsdigitalvision.zenfolio.com/p319746148/e80a4fc8
  15. I am not telling them what to produce( like they would listen to me!) I do not do any WW1 and I was thinking about Rickenbacker and the Hat in the ring and had an aha moment only to find out it was not on his list of AC. not a biggie I just thought with the buying power of the CONUS it would be a natural. He can do what ever he wants it is his company. I will look around for the old hobby craft...
  16. well ya and I know he is a commenwealth kinda guy but still.....
  17. in the usa the hat in the ring and Eddie rickenbacker is biggly. You would think hat in the ring and the usa etc?
  18. are all the flaps deformed or just yours? confused
  19. dashotgun

    Ne Mask

    it would help if you gave a general idea of how much it would cost. Would you make piece masks? ie not a whole aircraft worth just say a two piece mask of say Cripes a mighty?
  20. thanks Tony most of these were old photos not intended for the purpose of composits. Ongoing I will re photograph these as above
  21. they are metal diecast I think they are 1:35
