  1. Hello Ray Bristol did developed two-stage supercharged engines, but these were experimental types only. Pre-war Pegasus PE.6S powered Bristol 138A, which set a new altitude world record in 1937. In his book British piston aero-engines and their aircraft (Airlife) Alec Lumsden describes it as a hybrid, with a fully supercharged single stage and an extra second-stage supercharger. It required quite a large intercooler. Both Hercules VIII and XVTM had a second-stage supercharger added more or less in the same vein as PE.6S. Again, Lumsden calls both two-stage Hercules types hybrids. These en
  2. Hello Steve, induced drag would increase a bit with a larger wing area, however due to a better pressure distribution on rounded wingtips this would be more than offset by decreased wingtip vortices and consequently decreased induced drag. Momentary I am away from my library, but IIRC Martin Middlebrook wrote in his book The Nurmberg raid about a brand new Halifax, which arrived to the unit just before the raid. Her crew found out she can cruise at 27.000 ft, and they flew the raid high above flak and night fighters in absolute safety. Needles to say, they were delighted. Cheers
  3. Hello, Warhawk I checked Revell kit's wing in my stash and the situation is not that bad. Yes, quite a number of panels is inaccurate, but only few of them are either missing or are invented. Cheers Jure
  4. Hello Warhawk I cannot inspect my Revell at the moment, but IIRC the main problem lays with leading edge panels. Still, nothing that a bit of a putty and light sanding could not correct. Cheers Jure
  5. Panels instead of rivet lines on the wings, engine radiators ... This question has already been discussed here on BM: And then there is the original thread on the HS that inspired that debate: http://www.hyperscale.com/2013/reviews/kits/airfixa09007reviewmd_1.htm Cheers Jure
  6. Hello Much in the aviation depends on circumstances. Had the WWII lasted longer, both Ho 229 and B-35 would have been deployed operationally due to war necessity. Various wrinkles, which would have inevitably surface, would have been ironed on the go. As I said, I believe conventional low wing, engines beneath the wings formula is a recipe for ever increasing efforts and costs resulting in diminishing returns. Canard brings inherited benefit of reduced induced drag, allows for mid-wing configuration (Piaggio P.180 Avanti). Also, it would allow for installation of engines in the tail,
  7. Eric, I think Calquin was also made of wood, although a high altitude escort fighter Namcu was all metal. This one, however, resembled de Havilland Hornet and not Mosquito. Black Knight, a Mosquito victory still counted as one aircraft destroyed. However, I believe the equations you refer to were part of Luftwaffe pilots' internal count of adding points towards a highly appreciated sore throat remedy, better known as Knight's Cross. Cheers Jure
  8. Hello Thanks for the correction, J-W, duly noted. Some time ago I toyed with the idea of such a conversion as I wanted to build a 'long range' Bf 110 B in service during Fall Weiss. I had already converted the wings of the old Monogram kit, which, given the kit's shortcomings like incorrect wing's leading edge angle between the fuselage and the engine, perhaps was not a particularly wise choice. On the other hand, conversion of the kit's undernourished engines would probably be less complicated. Cheers Jure
  9. One also has to replace three bladed propellers with two bladed ones. Cheers Jure
  10. Hello old_tonto I am not an expert, but fortunately some of the other BM members are. So take a look at these models: I have no idea if AM Martin-Baker IRQ-7A seats are available in 1/72. I would speculate there are AM ejection seats on the market, that are similar enough so they can be converted to IRQ-7A without too much trouble. Cheers Jure
  11. Hello Wellsprop, I have already seen this topic, but thanks anyway. It does not look very promising. Still, one never knows what future holds. Consider the following: the first flying wing flew, I believe, in 1911. By the end of the world war II this was a proven concept with flying prototypes in many countries and multi-prototype/pre-series production of B-35 and B-49 flying wing bombers in the USA. With the end of hostilities these projects were mostly canceled. Not much happened for the next forty or so years, than B-2 appeared, and more recently several flying wing UAVs. Ano
  12. Hello bentwaters81tfw Try the following link: http://airwar.ru/other/draw3/dhc7-100.html Drawings are in pdf vector graphic, with plenty of measurements included and even some stations marked, so scaling them up to 1/72 should not be a problem. Cheers Jure
  13. Hello Graham, I disagree. That kind of reasoning got aircraft industry where it is now, when large investments produce diminishing results. Also, pushing the logic of small advantages to the hilt can produce, to put it mildly, unpleasant results - just think about 737-MAX. Wellsprop, yes, many parts and components on different modern airliners only vary proportionally one from another and many others are exactly the same. I agree standardization saves both time and money but these days 1 % increase in airliner's overall efficiency is considered a good result. To me this is a clear sign th
  14. Hello Wellsprop, I agree, designing aircraft costs both time and money. But, speaking about airliners only, why do manufacturers sticks to the same design philosophy since Comet, Tu-104 and B707? Apart from Mach 2 Tu-144 and Concorde every major airliner type followed the same formula. Optimization is the word, yes, but if a company throws tens of billions and a decade or two into a development of a new airliner, why not aiming at something revolutionary? After determining the basic configuration, development would proceed as usual. Work of thousands of engineers would remain the same and
  15. Hello Off the top of my head some of the units would be SKG 10 and SG 4: The photo shows one of the 10/SKG 10 aircraft, and this particular Fw 190 G-3 W. Nr. 160022 was captured intact on Montecorvino airfield near Salerno, Sicily. I found the photo on Asbiz page here. It is a rather poor reproduction with distorted colours, and despite her appearance, this plane was painted in standard RLM 74/75/76 scheme. As you noted Gondor, photos of G version are difficult to find. Some of them (three or four, I think) can be found, along with a few colour profiles, in Fw 190 JaBos, s
